The potentiometer should be connected sothat full resistance is connected from CM and REF. REF is a5VDC potentiometer reference output. The wiper of thepotentiometer should be connected at terminal VIN. The speedcommand input will be recognized at terminals CM and VIN.When using a potentiometer as the speed command, the AnalogCommand Select parameter will need to be programmed to 0 or1 and jumper J19 will need to be set properly.An external speed command of 0-5VDC, 0-10VDC, 0-20 mA, or4- 20mA can be used instead of a potentiometer at terminals CMand VIN.
