You have completed the inverter's basic commissioning.
Identifying the motor data and optimizing the closed-loop control
Following basic commissioning, the inverter generally has to measure other motor data and
optimize its current and speed controllers.
To start motor data identification, you must switch on the motor.
Risk of fatal injury as a result of machine movements when switching on the motor
Switching on the motor for identification purposes may result in hazardous machine
movements.
Secure dangerous machine parts before starting motor data identification:
• Before switching on, check that no parts are loose on the machine or can be spun out.
• Before switching on, ensure that nobody is working on the machine or located within its
• Secure the machine's work area against unintended access.
• Lower hanging/suspended loads to the floor.
Preconditions
● In the basic commissioning, you have selected the motor data 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
closed-loop speed control can become unstable.
