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).

Table 5.2

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.
