4 Faults and alarms
4.2 List of faults and alarms
F07990 Drive: Incorrect motor data identification
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
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. Separately excited synchronous
motors: damping resistance outside 1.0 ...15 % of Zn.
4: Identified stator reactance lies outside the expected range 50 ... 900 % of Zn. Separately excited synchronous
motors: stator reactance outside 20 ...500 % of Zn.
5: Identified magnetizing reactance lies outside the expected range 50 ... 900 % of Zn. Separately excited
synchronous motors: magnetizing reactance outside 20 ...500 % of Zn.
6: Identified rotor time constant lies outside the expected range 10 ms ... 5 s. Separately-excited synchronous
motors: damping time constant outside of 5 ms ... 1 s.
7: Identified total leakage reactance lies outside the expected range 4 ... 100 % of Zn.
8: Identified stator leakage reactance lies outside the expected range 2 ... 50% of Zn. Separately excited
synchronous motors: stator leakage reactance outside 2 ...40 % of Zn.
9: Identified rotor leakage reactance lies outside the expected range 2 ... 50% of Zn. Separately excited synchronous
motors: damping leakage reactance outside 1.5 ...20 % 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.
50: The selected sampling time is too low for the motor identification (p0115[0]).
Note:
Percentage values are referred to the rated motor impedance:
Zn = Vmot.nom / sqrt(3) / Imot,nom
Remedy: Re 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 Motor Module? The ratio of the
Motor Module to the rated motor current should not be less than 0.5 and not be greater than 4.
- check configuration (star-delta).
Re fault value = 11 in addition:
- Deactivate oscillation monitoring (p1909.7 = 1).
For fault value = 2:
- for parallel circuits, check the motor winding system in p7003. If, for power units connected in parallel, a motor is
specified with a single-winding system (p7003 = 0), although a multi-winding system is being used, then a large
proportion of the stator resistance is interpreted as feeder cable resistance and entered in p0352.
Re fault value = 4, 7:
- check whether inductances are correctly set in p0233 and p0353.
- check whether motor has been correctly connected (star-delta).
- Set p1909.0 = 1.
For fault value = 12:
- check the power cable connections.
- check the motor.
- check the CT.
For fault value = 50:
- Perform a motor data identification with a higher sampling time, and after this, change to the required higher
sampling time (p0115[0]).
