Drive: Motor data identification
Reaction: OFF2
Cause: An error has occurred during the identification run.
Fault value 1: Current limit reached.
(r0949): 2: Identified stator resistance outside range 0.1% to 100% of Zn.
3: Identified rotor resistance outside range 0.1% to 100% of Zn.
4: Identified stator reactance outside range 50% to 500% of Zn.
5: Identified main reactance outside range 50% to 500% of Zn.
6: Identified rotor time constant outside range 10ms to 5s.
7: Identified total leakage reactance outside range 5% to 50% of Zn.
8: Identified stator leakage reactance outside range 25% to 250% of Zn.
9: Identified rotor leakage reactance outside range 25% to 250% of Zn.
10: Motor is defective or not connected.
20: Identified threshold voltage outside range 0.5V to 10V.
30: Current controller in voltage limitation.
40: At least one identification contains errors. The identified parameters are not saved to
prevent inconsistencies.
50: Pulse frequency cannot be implemented with the set current controller sampling rate.
The percentages are referred to the rated impedance of the motors:
Zn = Vmot.nom / sqrt(3) / Imot,nom
Remedy: Fault value 0: Check whether the motor is connected correctly. Check connection type (star-
delta).
Fault value 1-40: Check whether motor data are entered correctly in P0300, P0304 - P0311.
Is the ratio between the power of the motor and the converter appropriate? The ratio
between converter current and motor current should not be less than 0.5 and not greater
than 4. Check connection type (star/delta).
Fault value 50: Reduce current controller sampling rate.
Acknowl.: Immediate
A7991
Drive: Motor data identification activated
Cause: Motor data identification activated. Motor identification is performed with the next ON
command.
See also: p1910
Remedy: Warning disappears after motor identification has been successfully completed.

F30001
Power section: Overcurrent
Reaction: OFF2
Cause: Power section has detected an overcurrent.
- Control incorrectly parameterized.
- Motor short-circuit or ground fault.
- V/f mode: Ramp-up set too low.
- V/f mode: Rated current of motor much higher that that of motor module
- Power line not properly connected.
- Power lines exceed maximum permissible length.
- Power section defective.
Fault value Bit 0: Phase R
(r0949): Bit 1: Phase S
Bit 2: Phase T
