Note
To set the new controller setting permanently, the data must be saved in a non
-volatile
memory.
Note
At the end of the motor data identification, all
dependent control parameters are calculated
automatically (p0340
= 3)
Motor data identification procedure
1. Activate motor data identification with p1900 = 2 (or p1910 = 1).
Alarm A07991 is displayed.
2. Motor data identification starts the next time that the motor is switched on.
3. After a successful motor data identification, parameter p1900 (or p1910) is reset to "0".
If the identification was not successful, then instead, fault F07990 is output.
4. Parameter r0047 indicates the actual status of the measurement or identification.
Measurement without automatic adaptation of the control parameters (p1909.17)
p1909.17 = 1 can be used, for example, to measure the motor parameters after a motor
replacement, without automatically adapting the control parameters via p0340.
