Stepper Output Wiring

NOTE: Do not use Vcc Out to power your encoder because:

• This output’s voltage is not regulated.

• 50 mA is not adequate current to power the encoder. Each of the encoder

outputs (A, B, and Z) requires 20 to 25 mA in addition to the current used by

the encoder’s internal circuit.

• Using this output to power the encoder would violate the isolation that exists

between the inputs and outputs.

NOTE: The Step and Dir outputs are generated by a differential driver, but the

Enable output is a relay. Therefore, power must be provided through the Enable

output, as shown in the diagrams below.

Drive with bipolar inputs:

Drive with common anode inputs:
