OPTO Opto-Isolator Supply
User supplied power for the opto-isolators.
PULSE Pulse Input
A low to high transition on this pin advances the motor one step. The step size is
determined by the Step Resolution switch setting.
DIR Direction Input
When this signal is high, motor rotation is clockwise. Motor rotation is counter-
clockwise
when this signal is low.
Clockwise and counter-clockwise directions are properly oriented when viewing the
motor from the end opposite the mounting flange.
AWO All Windings Off Input
When this signal is low, AC and DC current to the motor will be zero. There is no
holding torque when the AWO signal is low.
If you are using the drive with an MX2000, SS2000I or SS2000I-V
control, the READY input and the OPTO input on the control must be
jumpered together.
