Basic commissioning: Motor identification
Note
When motor identification has been completed, press the OFF key to cancel the power-on
inhibit.
When the rotating measurement is selected, the drive triggers movements in the motor that
can reach the maximum motor speed. The EMERGENCY OFF functions must be fully
operational during commissioning. To protect the machines and personnel, the relevant
safety regulations must be observed.

Selecting motor identification
To navigate through the selection fields,
choose <F2> or <F3>.
To activate a selection, choose <F5>.
Stationary measurement increases the
control performance, as this minimizes
deviations in the electrical characteristic
values due to variations in material
properties and manufacturing tolerances.
Rotary measurement determines the data
required (e.g., moment of inertia) for setting
the speed controller. It also measures the
magnetization characteristic and rated
magnetization current of the motor.
Number of phases to be identified:
• For identification with one phase, the
measurement time is significantly
reduced.
• For identification with several phases, the
measurement results are averaged.
To activate this function, press the LOCAL
key (wait until the LED in the LOCAL key
lights up) and then ON.
If motor identification is not carried out, the
motor control uses the motor characteristic
values calculated from the type plate data
rather than the measured values.
