Hello,

in your case I think that the only possibility is the jogging mode. Commands "Jog 1" or "Jog 2" switch the motor on and off automatically and as soon as the motor is on, the motor accelerates to the setpoint, jog 1 or setpoint, jog 2. The two different setpoints can, for example, be assigned to motor clockwise and counter-clockwise rotation.

Parameter Description

p1055 = 722.0 Jogging bit 0: Select jogging 1 via digital input 0

p1056 = 722.1 Jogging bit 1: Select jogging 2 via digital input 1

p1058[D] Jogging 1 speed setpoint

p1059[D] Jogging 2 speed setpoint 

Have a look at chapter 6.3.8 of the following manual:
