Always use a shielded cable when connecting to the inhibit terminal. The shield of the cable
should connect to the Common terminal of the DC Drive.
Speed pots can be replaced by 0–10V analog signals (PLC, etc.). For 0–10 VDC input signal,
please refer to “Operational Description: 0 to 10 VDC Analog Reference Signal to GSD1” on

Inhibit via speedpot
provides starting and stopping through accel parameters
Using inhibit input
provides fast start-stop by bypassing accel circuit
** Use shielded cable when connecting to the Inhibit terminal. Connect the cable shield to the Common terminal of P2.
