Additional Information

The 6SN1118-0DH23-0AA1 is a Digital, Closed-Loop, 2-Axis Simodrive Control Unit. The basic version of the Simodrive 2-axis control units comes standard with sinusoidal voltage signals and it is possible to connect the absolute encoders with the EnDat interface. The evaluation of the two measuring systems with the sinusoidal voltage signals and the connection with the absolute encodes witht eh EnDat interface and SSi interface is possible.

Although being a 2-Axis Control Unit, the Siemens 6SN1118-0DH23-0AA1 can also be operated in a single axis power module for single axis applications. It is engineered as a 1-axis board. For motor encoders without any adjustment to the EMF of the synchronous motor, an automation ID technique can be used to find the electrical rotor position. The ID routine is performed after each power up operation, and the mechanical motion is typically less than 5 degrees difference. Be sure when using non-PELV circuits at terminals AS1 and AS2 on the module that the connected are coded to prevent connectors from being inserted correctly. At terminals 19, P24, and M24 only PELV circuits should be connected. If this is not done, then electrical shock and personal injury can occur. When using the encoder, the inputs on the 6SN1118-0DH23-0AA1 should not be assigned any signals other than what it is intended for. If this is not done, then sporadic or continued malfunctioning could occur and the unit could be damaged. It is very important with spindle applications that available signals from additional temperature sensors are not connected to the CP-, CN-, DP-, and DN inputs when using an induction motor. When the “parking axis” is chose, the encoder can then be withdrawn and inserted under voltage. When handling the operating unit or interface, be sure to take protective measures such as workings with a grounded ESD wristband or wearing ESD shoes in connection with ESD flooring.
