If problems occur during the identification run, e.g. the current controller oscillates,
then the rating plate data should be re-checked and an approximately correct
magnetizing current P0320 entered. The motor data identification routine should
then be re-started by calling P0340 = 1 (refer to Section 3.5.3).

Factory setting: Bold
Ambient motor temperature (entered in °C)
The motor ambient temperature is entered at the instant that motor data is
being determined (factory setting: 20 °C).
The difference between the motor temperature and the motor ambient
temperature P0625 must lie in the tolerance range of approx. ± 5 °C. If this
is not the case, then the motor data identification routine can only be
carried-out after the motor has cooled down.
Select motor data identification
0 Disabled
1 Identification of all parameters with parameter change.
These changes are made and applied to the controller.
3 Identification of saturation curve with parameter change
NOTE:
For P1910 = 1 → P0340 is internally set to 3 and the appropriate data
calculated (refer to parameter list P0340)
Power-up the motor
The
ON command initiates the measuring operation. In so doing the motor aligns
itself and conducts current. Diagnostics via r0069 (CO: phase currents) is
possible. Alarm message A0541 (motor data identification routine active) is
output.
After the motor data identification routine has been completed:
1. P1910 is reset (P1910 = 0)
2. A0541 is withdrawn
