Commissioning
5.2 Preparing for commissioning
Switching the motor on and off in the jog mode
In the case of inverters with a PROFIBUS or PROFINET interface, operation can be
switched via digital input DI 3. The motor is either switched on and off via PROFIBUS – or
operated in jog mode via its digital inputs.
When a control command is received at the respective digital input, the motor rotates at
±150 rpm. The same ramp-up and ramp-down times as described above apply.

Minimum and maximum speed
● Minimum speed - factory setting 0 [rpm]
The minimum speed is the lowest speed of the motor independent of the speed setpoint.
A minimum speed is, for example, useful for fans or pumps.
● Maximum speed - factory setting 1500 [rpm]
The inverter limits the motor speed to this value.
Operate the inverter with the factory setting
For basic applications, you can try to operate the drive with a rated power < 18.5 kW without
any other commissioning steps. Check whether the control quality of the drive without
commissioning is adequate for the requirements of the application.
We recommend that you configure the drive with the precise motor data.
