Switching the motor on and off
The inverter is set in the factory as follows:
● After the ON command, the motor accelerates within the ramp-up time (referred to
1500 rpm) to its speed setpoint.
● After the OFF1 command, the motor brakes down to standstill with the ramp-down time.
● The negative direction of rotation is inhibited

Traverse the motor in the jog mode
For an inverter with PROFIBUS or PROFINET interface, operation can be switched over
using digital input DI 3. The motor is either switched on and off via the fieldbus – or operated
in the jog mode via its digital inputs.
For a control command at the respective digital input, the motor rotates with ±150 rpm. The
same ramp-up and ramp-down times as described above apply.
