Application Notes:
1.When wiring TTL signals to other manufacturer’s indexers, the Step TTL command signals from
the controller should be wired to Step + , the Direction signal to Dir + , and the Shutdown signal
to SD + ( Step - , Dir -, and SD - should not be connected). Remember to connect commons.
2.Activating the Shutdown input (logic low) disables the drive amplifier and de-energizes the motor.
When this input is off (logic high) the drive is enabled and the motor is energized.
