A motor with a single ended optical encoder
must be used in order for the encoder
feedback function to work. Connect the 5
wires from the encoder into P2 using a 5-Pin to
5-Pin connector which is provided with the
Designer’s Kit (purchased separately).

P3 – Motor/Controls/Power Interface
A 12-pin pluggable terminal strip connector P3 provides power and the step and direction control functions for
the module. All of these signals are optically isolated. Open-collector drives are required to provide pulses for
Step, levels for Direction, and Disable. The common +ve supply ranges from 5 VDC to 30 VDC with respect to the
signal input; however if the supply is greater than 5 VDC then a resistor must be inserted in series with each
signal line to limit the current to 10 mA.
