Additional Information

The UD51 Second Encode Small Option Module has inputs that allow for a secondary encoder to be connected to a Control Techniques Unidrive. It has standard quadrature encoders which have up to 16384 lines per revolution. This allows for a maximum operating frequency of 210 kHz or F/D signals up to 420kHz. If a Unidrive is operating in Closed-Loop Vector Mode or Closed-Loop Servo Mode, the UD 51 can give speed and position feedback for position control or digital locks, as well as accept frequency and directional reference input signals. The simulated encoder outputs on the UD51 normally uses the second encoder as its source, but can modified to use the main encoder as the source. These outputs can be configured for frequency and directional signals.

The Control Techniques UD51 must be installed in the small option module bay of the Emerson Unidrive. Connections to the drive are made by a multi-way connector and connections to external equipment must be made by a plug-in 16 way screw-terminal block. It is important to note that the STOP function of the drive does not remove dangerous voltages from any external option unit. Please be careful when operating or making adjustments to the drive.

The following list the terminal connections on the UD51 and their function.
