Simodrive 611 Error Code List with Fault/Warning Numbers

Reader’s note

  • In some instances, the space retainers (e.g. \%u) are specified for the texts of the individual faults and warnings. In online operation with SimoCom U instead of a space retainer, an appropriate value is displayed.

 

  • The complete list is updated corresponding to the Edition of this documentation (refer to the Edition in the header lines) and corresponds to the software release of ”SIMODRIVE 611 universal” documented here. The individual faults/warnings are not coded dependent on the software release.
000 Alarm diagnostics not possible
Cause — Communications to the drive have been interrupted.
— Different versions of the ”SimoCom U” start-up and
parameterizing tool and the drive.
Remedy — Check the communications to the drive (cable, interfaces, … )
— The V_611U<Version>.acc file on the hard disk of the PG/PC
should be adapted to the drive as follows:
— Exit ”SimoCom U”
— Delete the V_611U<Version>.acc file (search and delete the file)
— Restart ”SimoCom U” and go online
The V_611U<Version>.acc file is now re-generated and is
harmonized to the drive version.
Never delete the file V000000.acc!
001 The drive does not have firmware
Cause No drive firmware on the memory module.
Remedy — Load the drive firmware via SimoCom U

The actual rotor position and the position information read-out of the
encoder were compared with one another while booting and a deviation
of more than 45 Degrees was identified, P1011[10].
Operational:
The acceleration/velocity direction is different than the torque/force di-

— Operation may only be resumed after the fault has been removed
otherwise there is a danger of uncontrollable motion.
Ramp-up:
— The deviation is due to dirt on the encoder or incorrect mounting/
installation of the encoder or encoder cable.
Operational:
— If the load oscillates strongly increase the delay for the monitoring
(P1645).
— Caution : The value in P1645 influences the duration of the axis
motion, triggered by positive feedback until the fault responds.

on the heatsink. The drive is immediately shut down 20 seconds after
the heatsink temperature alarm in order to prevent the power section
being thermally destroyed (regenerative stop).
Remedy Improve the drive module cooling, e.g. using:
— Higher airflow in the switching cabinet, possibly cool the ambient air
of the drive modules
— Avoid many acceleration and braking operations which follow
quickly one after the other
— Check that the power section for the axis/spindle is adequate,
otherwise use a higher-rating module
— Ambient temperature too high (refer to the Planning Guide)
— Permissible installation altitude exceeded (refer to the
Planning Guide)
— Pulse frequency too high (refer to the Planning Guide)
— Check fan, if required, replace
— Maintain the minimum clearance above and below the power section
(refer to the Planning Guide)

591 Pos.contr.clock cycle not equal to DP clock cycle/mas-
ter applic. clock cycle
Cause For a 2-axis module, one axis is in the n-set mode and one axis in the
positioning mode. For the axis in the n-set mode, a position controller
clock cycle (of the master) is entered via the clock-cycle synchronous
PROFIBUS or the bus interface. This position controller clock cycle
differs from the parameterized position controller clock cycle (P1009) of
the axis in the positioning mode. The position controller clock cycle of
the master is obtained, in the n-set mode, from the DP clock cycle
(Tdp) or the clock cycle of the bus interface multiplied by the time grid
Tmapc.
Remedy For a clock cycle synchronous PROFIBUS (isochronous) or the bus
interface, the clock cycles configured for the bus (parameterization) are
aligned with the position controller clock cycle P1009 from the position-
ing axis and n-set axis.

592 Spindle positioning: Pos. contr. not equal to master
application clock cycle
Cause The function ”spindle positioning” requires, for a clock-cycle synchron-
ous PROFIBUS or the bus interface, that the position controller clock
cycle of the master matches the parameterized position controller clock
cycle (P1009). The position controller clock cycle of the master is ob-
tained from the DP clock cycle (Tdp) multiplied by the time grid Tmapc.
Remedy For the clock-cycle synchronous PROFIBUS or the bus interface, the
clock cycles configured for the bus (parameterization) are aligned with
the position controller clock cycle P1009.

Remedy 1FN3 linear motors (if P1075=1):
Measure the rotor position offset to the EMF of the U_R phase and add
to P1016 as the commutation angle offset. Then set P1017 to –1 in
order to save the serial number of the EnDat encoder.
otherwise:
To determine commutation angle offset in P1016, initiate the rotor posi-

606 Flux controller output limited
Cause The specified flux setpoint cannot be realized, although maximum cur-

— Motor data are incorrect
— Motor data and motor connection type (star/delta) do not match
— Motor has stalled because motor data are extremely inaccurate
— Current limit is too low for the motor (0.9 * P1238 * P1103 < P1136)

607 Current controller output limited
Cause The entered setpoint cannot be impressed in the motor, although the
maximum voltage has been entered. The cause could be that the motor
is not connected, or a phase is missing.
Remedy — Check the connecting cable, motor/drive converter (phase missing)
— Check the motor contactor
— DC link voltage present?
— Check the DC link busbar (check that the screws are tight)
— Uce monitoring function in the power section has responded
(RESET by powering off/powering on)

608 Speed controller output limited
Cause The speed controller is at its limit for an inadmissibly long time (torque
and current limit). The permissible duration is defined in P1605, the
speed upper limit up to when the monitoring responds is defined in
P1606.
Synchronous motor:
In normal operation, the correct, optimized axis drive should never
reach its current limit — not even for extremely large speed changes
(changeover sequences from rapid traverse in the positive direction to
rapid traverse in the negative direction).
P1605 = 200 ms
P1606 = 8000 rev/min
Induction motor:
Acceleration and braking with the maximum torque/current are usual in
operation, only a stalled drive (0 speed) is monitored.
P1605 = 200 ms
P1606 = 30 rev/min
1. At the first commissioning, after the software has been replaced or
the software has been upgraded, after the parameters have been en-
tered the ”calculate motor data” or ”calculate controller data” function
was not executed. The drive then keeps the default values (for the val-
ues to be calculated this is zero) which can, under certain circum –
stances, result in this fault (P1605 and P1606 should be adapted to the
mechanical and dynamic capabilities of the axis).
2. An undesirable input of a high torque reduction via the analog inputs
or via PROFIBUS and the bus interface. For PROFIBUS and the bus
interface, this effect especially occurs when changing from the position-
ing mode to the speed setpoint input mode (check as to whether a
torque reduction is entered. Diagnostics using P1717, 0%: No torque,
100%: Full torque).
Remedy — Check connecting cable motor/converter (phase missing, exchanged)
— Check the motor contactor
— Check the torque reduction (P1717)
— DC link voltage present?
— Check the DC link voltage (check that the screws are tight)
— Unblock the motor
— Is the motor encoder connected?
— Check the motor encoder cable screen
— Is the motor grounded (PE connection)?
— Check the encoder pulse number (P1005)
— Does the encoder cable fit to the encoder type?
— Check the direction of rotation of the encoder tracks (e.g. toothed-
wheel encoder, P1011)
Adapt parameters P1605 and P1606 to the mechanical and dynamic
capabilities of the axis. Check whether a torque reduction has been
entered (diagnostics via P1717, 0%: no torque, 100%: full torque).
For linear motors:
— Check actual value inversion
— Check the reduction in the maximum motor current (P1105) and if
required increase the value
— Check the power cable connection
— For the parallel circuit configuration, are the motors correctly as-
signed and electrically connected?

Cause if P1075=1 (technique based on saturation)
A rotor position could not be determined from the measurement signals
(motor current), as no significant saturation effects occurred.
Also refer to parameter P1734 for detailed diagnostics.
if P1075=3 (motion-based technique)
1. Current increase too low.
2. Maximum permissible duration exceeded.
3. No clear rotor position found.

— Increase current via P1019
— Check armature inductance (P1116) and if required, increase
— Check the connecting cable, motor/drive converter (phase missing)
— Check the motor contactor
— DC link voltage present?
— Check the DC link busbar (check that the screws are tight)
— Uce monitoring function in the power section has responded
(RESET by powering off/powering on)
— Replace the power section or control module
if P1075=3
To 1.
— The motor is not correctly connected
— The motor power connection must be checked
To 2.
— Remove disturbing external forces (e.g. axis couplings which are not
released)
— Identification technique must remain stable (P1076 must be reduced)
— Use an encoder with higher resolution
— Improve the encoder mounting (it is not stiff enough)
To 3.
— Remove disturbing external forces (e.g. axis couplings which are not
released)
— The axis must be able to freely move (e.g. the motor rotor may not be
locked)
— Reduce the high axis friction (increase P1019)

611 Illegal motion during rotor position identification
Cause During the rotor position identification (motor current measurement),
the motor rotated more than the value entered in P1020. The rotation
could be caused by having powered on with the motor already rotating,
or caused by the identification routine itself.
Remedy if P1075=1
— If the interchange was caused by the identification itself and if the
error occurs again, then reduce P1019 or increase P1020.
— Lock the motor rotor during the identification routine.
if P1075=3
— Increase the parameterized load mass (P1076)
— Check the maximum permissible motion (P1020) and if required,
increase
— Reduce the current, rotor position identification (P1019)
If the current and speed controller clock cycle have low values (62.5

A resolver has been selected the pole pair number (P1018) of which is

760 Pole pair width/scale graduations cannot be repre-
sented internally
Cause For linear motors, the equivalent (internal) pole pair number and (inter-
nal) encoder pulse number are calculated from the pole pair width and
grid division. In this case, the encoder pulse number must be an integer
multiple of one or x pole pair widths. This error message is output if the
pole pair width/grid division * x (up to x=4096) is not an integer multiple
or if an internal encoder pulse number which was calculated is too high.
A result with a tolerance of +/– 0.001 absolute is interpreted to be an
integer.
Remedy Long travel paths:
A linear measuring system with an encoder mark number that is an in-
tegral divisor of x* pole pair widths should be used.
Short travel paths:
For short travel, only a low error can accumulate which has hardly any
effect on the maximum achievable force and on the temperature rise, if
the encoder pulse number fits with a deviation of more than +/–0.001 in
the pole pair width. We then recommend that the pole pair width is
slightly changed.

motor temperature reaches the alarm threshold, motor overtemperature
(P1602 for KTY or the PTC-specific switching temperature for PTC).
2. The thermal motor model has reached the thermal motor utilization
alarm threshold P1269.
Remedy — Avoid many acceleration and braking operations which follow one
another quickly.
— Check whether the motor output is sufficient for the drive, otherwise
use a more powerful motor, possibly together with a higher-rating
power section.
— Check the motor data. It is possible that the motor current is too high

master
Cause The bus interface is in the data exchange state and was selected using
the parameterizing telegram of the clock-cycle synchronous operation.
It was not possible to synchronize to the clock cycle specified by the
master and to the master sign of life.
Causes:
— The master does not send an equidistant global control frame al-
though clock synchronism has been selected via the bus configuration.
— The master uses a different equidistant DP clock cycle as was com-
municated to the slave in the parameterizing telegram.
— The master does not increment its sign-of-life in the configured time
grid Tmapc.
Remedy Check master application and bus configuration
Check the consistency between the clock cycle input for the slave con-
figuring and the clock cycle setting at the master.

Prm_Structure (state 3, bit3) missing in the DPV1 header although
an isochron block (ID 0x04) is available.
21 = The time Tdx is greater than (To — 125us) or greater than
(Tdp — 250  s).
22 = The time Tpllw is greater than 1us.
23 = Slave- to-slave communication access target address and length
do not conform to word boundary.
24 = Maximum number (3 external + 1 internal) of slave-to-slave
communication links has been exceeded.
25 = Maximum number (8) of accesses per link has been exceeded.
26 = Unknown version ID in the slave-to-slave communications block.
27 = The maximum overall length of the filter table has been exceeded.
31 = The permitted maximum length of the parameterizing telegram for
the option module has been exceeded.
32 = The option module firmware does not support slave-to-slave
communications

present in the power module.
2 = The number of axes configured in the master is not equal to the
number axes for which the PROFIBUS-DP option module is
actively switched via P0875. Note: Even if axis B is de-activated
(passivated), communications with axis B are not automatically
de-activated.
3 = Configuration incomplete (too short) for one of the PPL types
(only for vor P875 = 2).
4 = No PPO type detected (only for P875 = 2).
5 = Length calculation different between firmware and option module.
6 = For active data exchange, a new configuration was received with
different length.
7 = Configuration contained unknown S7 ID.
19 = More PZD’s have been configured than the maximum permissible.
20 = The configurtion contains an unknown special character
(only axis separators are permitted).

number of accesses in the parameterizing telegram.
29 = Setpoint PZDs are not uniformly supplied by the master or slave
(drive) publisher.
30 = The permitted maximum length of the configuration telegram for
the option module has been exceeded.

to the master sign-of-life.
Causes:
— The master does not send an equidistant global control frame al-
though clock synchronism has been selected via the bus configuration.
— The master uses a different equidistant DP clock cycle as was com-
municated to the slave in the parameterizing telegram.
— The master increments its sign-of-life (STW2 Bits 12–15) not in the
configured time frame Tmapc.

Modicon Quantum System

Modicon Quantum Automation Platform

MRO Stock carries a number of popular Modicon Quantum Automation products. The Quantum system is a special purpose computing system which has digital processing capabilities. It was designed by Modicon to have real-time control in manufacture ring and other industrial applications while using a modular, expandable architecture.

It utilizes the following modules:
– Power Supply
– CPU
– I/O
– I/O Network Interface
– Intelligence / Special Purpose I/O
– Simulator
– Backplanes
– CableFast Cabling

Power supplies are crucial to the Quantum system, as they provide system power to all modules in the backplane, including the CPU, Interface, and I/O Modules. Depending on your system, there are 3 basic power supply modes. Standalone, which is for configurations that do not have fault tolerant or redundant capabilities. Standalone Summable, which is for systems using more than the rated current of one supply. With this mode, two summing power supplies can be installed on a single backplane. Redundant is the last mode, which is for configurations needing power for uninterrupted system functionality. Two redundant power supplies are needed for this mode.

The CPU is another critical component of the Quantum system. The CPU uses programmable memory to store user instructions and is a digitally operating electronic system. The CPU allows for various types of machines and processes to be controlled. It also serves as the Bus master controlling the distributed Inputs and Outputs of the configuration.

Quantum I/O’s are software configurable electrical signal converters that take signals from field devices and allow them to be processed by the CPU. All I/O modules are isolated from the Bus, keeping operation safe and hazard-free. It can process a number of field devices, including limit switches, proximity switches, temp sensors, solenoids, and valve actuators.

AS-BDAU-204 Analog Output Module

AS-BDAU-204 Wiring

For this module, use 60/75 copper (Cu) for the power connections and 4.5 in-lb. of torque for the set screws.
To prevent errors in field device operation, follow these guidelines:

  • Use shielded, twisted-pair cable (such as Belden 9418).
  • Ground the shield of each signal cable at the AS-BDAU-204 only. At the other end of each signal cable, peel back the shield and insulate it from contact with the signal-carrying wires.
  • Route each signal cable as far as possible from the sources of electrical noise (such as motors, transformers, contactors, and especially AC drives.
  • If the signal cables must corss AC or power cables, ensure that they cross at right angles.
  • When connecting field devices to the module, keep the unshielded portions of the signal-carrying wires as short as possible

After wiring the terminal blocks, use the supplied keys to prevent the blocks from being switched inadvertently.

DAU-204 Wiring Diagram: The following illustration is a wiring diagram and simplified schematic for the DAU-204 analog output module. 

AS-BDAU-204 Wiring Diagram
AS-BDAU-204 Wiring Diagram

We reccomend that you connect the AS-BDAU-204 to the same 24 Vdc power supply being used to power the PLC (even if the module is in the rack but not being used). If this is not possible, we recommend that you supply power to the PLC before the DAU 204 using a power supply similar to the P120 (quick startup voltage). Failture to observe this precaution can cause abnormal operation.

Ensure that the voltage loads driven by the module can tolerate transients during rack and module startup. During startup, transients as great as 2 V may appear on the voltage output terminals for as long as 5 ms due to the characteristics of semiconductor devices. This does not occur with the module’s current output terminals.

Terminals 3, 5, 9, and 11 (- current out, and – voltage out) are internally tied as a group. Terminals 14, 16, 20, and 22 (- current out, and – voltage out) are internally tied as a group. Be sure not to cross groups.

You should short all unused current output terminals to disable the red current loop LEDs and alarm bit.

MRO Stock stocks a large number of AS-BDAU-204’s. To order a replacement/spare, or for technical support, call 800-691-8511 or email sales@mrostock.com

Unidrive Sizing

Control Techniques UNI3405 Unidrive

The UNI3405 Unidrive has 4 essential Modes:

1. Open Loop mode (OL)

For use with standard AC induction motors. The UNI3405 applies power to the motor at frequencies varied by the user. The motor speed is a result of the output frequency of the drive and slip due to the mechanical load. The drive can improve the performance of the motor by applying slip compensation. The performance at low speed depends on whether V/f mode or open loop vector mode is selected.

V/f mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where a voltage boost is provided which is set by the user. This mode should used for multi-motor applications. Typically 100% torque at 4Hz.

Open loop vector mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where the drive uses motor parameters to apply the correct voltage to keep the flux constant under varying load conditions. Typically 100% torque at 1Hz.

2. Closed loop vector mode (VT)

For use with induction motors with a speed feedback device fitted. The UNI3405 directly controls the speed of the motor using the feedback device to ensure the rotor speed is exactly as demanded. Motor flux is accurately controlled at all times to provide full torque all the way down to zero speed. Typically 175% torque at 0rpm.

3. Servo (SV)

For use with permanent magnet brushless motors with a speed and position feedback device fitted. The Unidrive directly controls the speed of the motor using the feedback device to ensure the rotor speed is exactly as demanded. Flux control is not required because the motor is self excited by the permanent magnets which form part of the rotor. Absolute position information is required from the feedback device to ensure the output voltage is accurately matched to the back EMF of the motor. Typically 175% torque at 0rpm

4. Regen

For use as a regenerative front end for four quadrant operation. Regen operation allows bi-directional power flow to and from the AC supply. This provides far greater efficiency levels in applications which would otherwise dissipate large amounts of energy in the form of heat in a braking resistor. The harmonic content of the input current is negligible due to the sinusoidal nature of the waveform when compared to a conventional bridge rectifier or thyristor front end.

Control Techniques Unidrive UNI1405

Visit our UNI1405 Product Page for Purchasing Information

The incredibly versatile UNI1405 was one of the first universal AC drive capable of providing V/Hz, open and closed loop vector, servo and regenerative control in every unit. It combines all five AC drive technologies so you only have to learn one drive, support one drive and inventory one drive. For quick setup of basic applications, the Unidrive’s most common parameters are arranged in one concise menu. Hundreds of user-configurable functions separated into 20 logical menus provide quick setup for advanced application. For positioning, ratio control, camming and multi-axis systems, plug-in option modules easily extend the UNI1405’s capabilities. High horsepower Unidrives cover the range from 200 to 1600 HP. The 300 amp power module and control pod (the “brain”) are available as components. They are also available as a packaged drive solution that includes fusing and a disconnect. (See our Packaged Drive Section, pages 120-123 and 128-133.) With the Unidrive’s extensive selection of communication, application, feedback and I/O modules, you can easily upgrade the performance of your drive. Yet, it is simple to configure by using the drive keypad, a remote keypad (CTKP), or UniSoft, our Windows based drive set-up tool. You can tailor each Unidrive to be the drive you want when you want it.

Motion Control & Regen Applications

The UNI1405 is suited for use with AC brushless servo motors. Servo control is ideal for applications requiring load transfer to and from any position, at any speed. The Unidrive is designed for both stand-alone and multi-axis system applications.

In regen mode, two standard Unidrives operate together to provide full four-quadrant control of an AC motor. The system consists of two basic sub-systems, one being a Unidrive operating in any of its standard operating modes (open loop, vector or servo), and the other is a Unidrive operating in its regenerative mode. The link between the two sub-systems is simply the DC bus connections. In this mode, the Unidrive is capable of either supplying power to the DC bus of the Unidrive controlling the motor or removing power from the DC bus of the Unidrive controlling the motor and returning it back to the power line.

Please call 1-800-691-8511 or e-mail sales@mrostock.com for a UNI1405 price quote or for more information on Control Techniques products.

There exists some important design differences between various models of Quantum power supplies that require careful consideration by the system designer in order to achieve maximum system performance. The principal difference lies in the generation within the power supply of important backplane signals related to the health of the power supply and the status of the input power. All Quantum power supplies include on-board early power fail detection logic which is used to signal all other modules on the backplane that input power has failed. This signal is called POK (power OK) and is active high (i.e., when the signal is high, power is OK). There is both an internal (to the power supply) and an external (as seen by the backplane and all other modules) version of the POK signal. The internal POK signal is represented by the Pwr ok LED (light emitting diode) on the front panel of all power supplies. The system POK signal is generated so that there is sufficient time between the negative going edge of system POK (power has failed) and the actual interruption of power to the backplane. This early warning of power failure is necessary for the Quantum executive to perform an orderly system shutdown.

The 140CPS11420 is a Summable Power Supply. A summable power supply may be used as a standalone power supply without reservation in any Quantum system.
