Cause:
A fault has occurred during the identification routine.
Fault value (r0949, interpret decimal):
1: Current limit value reached.
2: Identified stator resistance lies outside the expected range 0.1 ... 100% of Zn.
3: Identified rotor resistance lies outside the expected range 0.1 ... 100% of Zn.
4: identified stator reactance lies outside the expected range 50 ... 500 % of Zn.
5: identified magnetizing reactance lies outside the expected range 50 ... 500 % of Zn.
6: Identified rotor time constant lies outside the expected range 10 ms ... 5 s.
7: identified total leakage reactance lies outside the expected range 4 ... 50 % of Zn.
8: Identified stator leakage reactance lies outside the expected range 2 ... 50% of Zn.
9: Identified rotor leakage reactance lies outside the expected range 2 ... 50% of Zn.
10: Motor has been incorrectly connected.
11: Motor shaft rotates.
12: Ground fault detected.
15: Pulse inhibit occurred during motor data identification.
20: Identified threshold voltage of the semiconductor devices lies outside the expected range 0 ... 10 V.
30: Current controller in voltage limiting.
40: At least one identification contains errors. The identified parameters are not saved to prevent inconsistencies.
60: Incorrect power stack data for the calibration of the converter output voltage
61: Incorrect measured values for the calibration of the converter output voltage
Note:
Percentage values are referred to the rated motor impedance:
Zn = Vmot.nom / sqrt(3) / Imot,nom
Remedy:
For fault value = 1 ... 40:
- check whether motor data have been correctly entered in p0300, p0304 ... p0311.
- is there an appropriate relationship between the motor power rating and that of the power unit? The ratio of the power unit
to the rated motor current should not be less than 0.5 and not be greater than 4.
- check connection type (star-delta).
For fault value = 4, 7:
- check whether the inductance in p0233 is correctly set.
- check whether motor has been correctly connected (star-delta).
For fault value = 11 in addition:
- deactivate oscillation monitoring (p1909.7 = 1).
For fault value = 12:
- check the power cable connections.
- check the motor.
- check the CT.
A07991 (N)
Drive: Motor data identification activated
Reaction:
NONE
Acknowledge:
NONE
Cause:
The motor data identification routine is activated.
The motor data identification routine is carried out at the next switch-on command.
If rotating measurement is selected (see p1900, p1960), it will not be possible to save the parameter assignment. Once
motor data identification has been completed or deactivated, the option to save the parameter assignment will be made
available again.
See also: p1910 (Motor data identification selection)
Remedy:
Not necessary.
The alarm automatically disappears after the motor data identification routine has been successfully completed or for the
setting p1900 = 0.
