Reverse Operation

Terminal P4–REV is the forward/reverse control. You can reverse motor direction by connecting P4–REV to P4–COM. Use a jumper wire, switch, relay, or an open collector NPN transistor.

Caution: Before reversing directions, make sure the motor is stopped. This control is not designed for plug reversing.

Sometimes it may be necessary to reverse motor direction without using terminal P4–REV. This is done by stopping the motor and exchanging terminals P1–Φ1 with P1–Φ2 on the lower board, and terminals P4–S1 with P4–S3 on the upper board.
