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 3.5.4).

Select motor data identification with P1910 = 1
p1910 = 1: Identifies the motor parameter with parameter change.
These are accepted and applied to the controller.
When p1910 = 1 is selected, Alarm A0541 (motor data identification active)
is output, and internally p0340 is set to 3.
Starts the motor data identification run with p1910 = 1
The measuring operation is initiated with the continuous (steady-state) ON
command. The motor aligns itself and current flows through it. Diagnostics is
possible using r0069 (CO: Phase current).
After the motor data identification routine has been completed, p1910 is reset
(p1910 = 0, motor data identification routine inhibited) and Alarm A0541 is
cleared (deleted).
In order to set the frequency converter into a defined state, an OFF1 command
must be issued before the next step.
Select motor data identification with P1910 = 3
p1910 = 3: Identifies the saturation characteristic with parameter change.
When p1910 = 3 is selected, Alarm A0541 (motor data identification active)
is output and internally, p0340 is set to 2.
Starts the motor data identification run with P1910 = 3
The measuring operation must be started with a continuous ON command.
After the motor identification routine has been completed, p1910 is reset
(p1910 = 0, motor data identification routine inhibited) and Alarm A0541 is
cleared (deleted).
In order to set the frequency converter into a defined state, an OFF1 command
must be issued before the next step.
