Commissioning
5.4 Basic commissioning using a PC
● You selected a method of motor data identification during basic commissioning, e.g.
measurement of the motor data while the motor is stationary.
When basic commissioning is complete, the inverter issues alarm A07991.
● The motor has cooled down to the ambient temperature.
An excessively high motor temperature distorts the results of motor data identification.
To initiate motor data identification and optimize the motor control, proceed as follows:
1. Open the control panel.
Figure 5-7 Control panel
2. Assume master control for the inverter.
3. Set the "Enable signals"
4. Switch on the motor.
The inverter starts the motor data identification. This measurement can take several
minutes. After the measurement, the inverter switches off the motor.
5. Relinquish the master control after the motor data identification.
6. Press button
(RAM to ROM).
You have completed the motor data identification.
