F07990 Drive: Incorrect motor data identification
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.
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.
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.
Remedy: Re fault value = 0:
- check whether the motor is correctly connected. Observe configuration (star-delta).
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 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 configuration (star-delta).
Re fault value = 4, 7:
- check whether inductances are correctly entered in p0233.
- check whether motor has been correctly connected (star-delta).
A07991 (N) Drive: Motor data identification activated
Reaction: NONE
Acknowledge: NONE
Cause: The motor data ident. routine is activated.
The motor data identification routine is carried out at the next power-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: None necessary.
The alarm automatically disappears after the motor data identification routine has been successfully completed or
for the setting p1900 = 0.
A07994 (N) Drive: motor data identification not performed
Reaction: NONE
Acknowledge: NONE
Cause: Motor data identification has not yet been performed with the actual data set.
The alarm is only triggered if the selection of the data set changes (see r0051) and vector control is parameterized
(p1300 >= 20) in the new data set selected and motor data identification has not yet been performed (see r3925).
Remedy: - Perform motor data identification (see p1900).
- Return data set.
- Parameterize V/f control (p1300 < 20).
