4 – CONNECT A CONTROLLER – INPUTS & OUTPUTS
Connect your controller cable to the DRIVE I/O connector, a 25 pin D-
connector on the front of the drive. The cable that comes with Compu-
motor controllers is prewired for compatibility with the E-AC Drive—you
can plug the cable directly into the E-AC Drive’s DRIVE I/O connector.

Drive I/O Connector
Descriptions of each function on the 25 pin D-connector follow.
STEP INPUT
For every step pulse it receives on its step input, the drive will commutate
the motor to increment rotor position. To send a step pulse to the drive,
apply a positive voltage to STEP+ with respect to STEP–. The drive regis-
ters the pulse on the rising edge.
