Commissioning
4.2 Commissioning with BOP-2 operator panel
Preconditions
● In the basic commissioning, you have selected the motor identification (MOT ID). In this
case, after the basic commissioning has been completed, the inverter issues the alarm
A07991.
● The motor has cooled down to the ambient temperature.
If the motor is too hot, the motor data identification will provide incorrect values and the
vector control can become unstable.
Procedure
To initiate motor data identification and optimization of the vector control, proceed as follows:
1.
2.
3.
4.
5.
6.
7.
8.
You have now completed motor data identification and the vector control has been
optimized.

You can recognize an active alarm from the corresponding symbol on the
BOP-2.
Press the HAND/AUTO key. The BOP-2 displays the HAND
⇒ symbol.
Switch on the motor.
Wait until the inverter switches off the motor after completion of the
motor data identification. The measurement takes several seconds.
Save the measurements so that they are protected against power
failure.
If you have also selected a rotating measurement in addition to the
motor data identification, then the inverter again issues the alarm
A07991.
Switch the motor on again in order to optimize the vector control.
Wait until the inverter switches off the motor after completion of the
optimization. The optimization can take up to one minute.
Switch the inverter control from HAND to AUTO.
Save the measurements so that they are protected against power
failure.
