Cautiont:
After the motor data identification (p1910 > 0) has been selected, alarm A07991 is output and a motor data identifi-
cation routine is carried-out as follows at the next power-on command:
- current flows through the motor and a voltage is present at the drive converter output terminals.
- during the identification routine, the motor shaft can rotate through a maximum of half a revolution.
- however, no torque torque is generated.
Notice:
In order to permanently accept the determined settings they must be saved in a non-volatile fashion (p0971,
p0977).
Note:
When setting p1910, the following should be observed:
1. "With transfer" means:
The parameters specified in the description are overwritten with the identified values and therefore have an influ-
ence on the controller setting.
2. "Without transfer" means:
The identified parameters are only displayed in the range r1912 ... r1926. The controller settings remain
unchanged.
Description:
Selects the number of phases to be identified.
The accuracy of the identification routine is higher if several phases are identified - however, the time required to
make the measurements also increases.
Values:
1:
1 phase U
2:
2 phases U, V
3:
3 phases U, V, W
Description:
Displays the identified stator resistance.
Index:
[0] = Phase U
[1] = Phase V
[2] = Phase W
Description:
Displays the identified rotor time constant.
Index:
[0] = Phase U
[1] = Phase V
[2] = Phase W
