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.
