4 Faults and alarms
4.2 List of faults and alarms
Remedy: Fulfill the conditions for the friction characteristic.
For alarm value = 1538:
Check the upper effective torque limit (e.g. in the field weakening range).
For alarm value = 1539:
Check the lower effective torque limit (e.g. in the field weakening range).
For alarm value = 3820 ... 3839:
Fulfill the conditions to set the parameters of the friction characteristic.
If the motor data (e.g. the maximum speed p0322) are changed during commissioning (p0010 = 1, 3), then the
technological limits and threshold values, dependent on this, must be re-calculated by selecting p0340= 5).
A07961 Drive: Friction characteristic record activated
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The automatic friction characteristic record is activated.
The friction characteristic is recorded at the next switch-on command.
When plotting the friction characteristic, it is not possible to save the parameters (p0971, p0977).
Remedy: Not necessary.
The alarm disappears automatically after the friction characteristic record has been successfully completed or the
record is de-activated (p3845 = 0).
F07963 Drive: Friction characteristic record interrupted
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF1
Acknowledge: IMMEDIATELY
Cause: The conditions to record the friction characteristic are not fulfilled.
Fault value (r0949, interpret decimal):
0046: Missing enable signals (r0046).
1082: The highest speed value to be approached (p3829) is greater than the maximum speed (p1082).
1084: The highest speed value to be approached (p3829) is greater than the maximum speed (r1084, p1083, p1085).
1087: The highest speed value to be approached (p3829) is greater than the maximum speed (r1087, p1086, p1088).
1110: Friction characteristic record, negative direction selected (p3845) and negative direction inhibited (p1110).
1111: Friction characteristic record, positive direction selected (p3845) and positive direction inhibited (p1111).
1198: Friction characteristic record selected (p3845 > 0) and negative (p1110) and positive directions (p1111)
inhibited (r1198).
1300: The control mode (p1300) has not been set to closed-loop speed control.
1755: For encoderless closed-loop control (p1300 = 20), the lowest speed value to be approached (p3820) is less
than or equal to the changeover speed, open-loop controlled operation (p1755).
1910: Motor data identification activated.
1960: Speed controller optimization activated.
3820 ... 3829: speed (p382x) cannot be approached.
3840: Friction characteristic incorrect.
3845: Friction characteristic record de-selected.
Remedy: Fulfill the conditions to record the friction characteristic.
For fault value = 0046:
- establish missing enable signals.
For fault value = 1082, 1084, 1087:
- Select the highest speed value to be approached (p3829) less than or equal to the maximum speed (p1082, r1084,
r1087).
- Re-calculate the speed points along the friction characteristic (p0340 = 5).
For fault value = 1110:
- Select the friction characteristic record, positive direction (p3845).
For fault value = 1111:
- Select the friction characteristic record, negative direction (p3845).
For fault value = 1198:
- Enable the permitted direction (p1110, p1111, r1198).
