Logic Wiring
All logic and control connections are made at the control terminal strip located on the motor control board. Screw type terminals are provided for easy connection to your external control station and meters. The control terminal strip can be divided into four major categories as follows:
1)Analog command inputs.
2)Analog outputs.
3)Opto Isolated inputs.
4)Relay outputs.
Analog Command Inputs
An external 5kohm potentiometer can be connected at terminals CM, VIN, and REF. The potentiometer should be connected so that full resistance is connected from CM and REF. REF is a 5VDC potentiometer reference output. The wiper of the potentiometer should be connected at terminal VIN. The speed command input will be recognized at terminals CM and VIN. When using a potentiometer as the speed command, the Analog Command Select parameter will need to be programmed to 0 or 1 and jumper J19 will need to be set properly.
