Commissioning
5.2 Preparing for commissioning
Switching the motor on and off
The inverters are set in the factory in such a way that, after switching on, the motor will
accelerate up to its speed setpoint in 10 seconds (referred to 1500 rpm). After it has been
switched off, the motor also brakes with a ramp-down time of 10 seconds.
Figure 5-1 Switching on and switching off the motor and reversing in the factory setting
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 ramp-up and ramp-down times are also 10 seconds, referred to 1500 rpm.

Operating the motor with the factory settings
In simple applications, you can attempt to operate the drive with a power rating < 18.5 kW
without having commissioned it. Check that the control quality of the drive is good enough for
the requirements of the application without commissioning.
We recommend configuring the drive with the precise motor data.
