Description (Factory setting: Bold)
Action
P0625 = ?
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.
Is the motor temperature (P0625) within the tolerance described above. If not the motor must be allowed to cool down.
P1910 = 1
Select motor data identification
0: Disabled
1: Identification of all parameters that have change. These changes are 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)
ON
Power-up the motor
The measuring operation must be started with a continuous ON command. If 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.
A0541
After the motor data identification routine has been completed:
1. P1910 is reset (P1910 = 0)
2. A0541 is withdrawn
OFF1
In order to set the inverter into a defined state, an OFF1 command must be issued before the next step.
P1910 = 3
Select motor data identification
0: Disabled
1: Identification of all parameters that have change. These changes are applied to the controller.
3: Identification of saturation curve with parameter change
Note: For P1910 = 3 → P0340 is internally set to 2 and the appropriate data calculated (refer to parameter list P0340)
ON
Power-up the motor
The measuring operation must be started with a continuous ON command.

After the motor data identification routine has been completed:
1. P1910 is reset (P1910 = 0)
2. A0541 is withdrawn
