Deactivate technique (p1982).
For fault value = 17:
Repeat technique.
A07971 (N) Drive: Angular commutation offset determination activated
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The automatic determination of the angular commutation offset (encoder adjustment) is activated (p1990 = 1, 3).
Note:
The automatic determination is carried out at the next switch-on command.
See also: p1990 (Encoder adjustment determine angular commutation offset)
Remedy: Not necessary.
The alarm automatically disappears after determination or for the setting p1990 = 0.
Reaction upon N: NONE
Acknowl. upon N: NONE
A07975 (N) Drive: Travel to the zero mark - setpoint input expected
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The zero mark must be evaluated in order to adjust the encoder.
It is expected that a speed or torque setpoint is entered.
See also: p1990 (Encoder adjustment determine angular commutation offset)
Remedy: Not necessary.
The alarm disappears once the zero mark has been detected.
Reaction upon N: NONE
Acknowl. upon N: NONE
A07976 Drive: Fine encoder calibration activated
Message value: Parameter: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The alarm indicates the phases of the fine encoder calibration using the alarm value.
Alarm value (interpret decimal):
1: Fine encoder calibration active.
2: Rotating measurement started (set the setpoint speed > 40 % rated motor speed).
3: Rotating measurement lies within the speed and torque range.
4: Rotating measurement successful: pulse inhibit can be initiated to accept the values.
5: Fine encoder calibration is calculated.
10: Speed too low, rotating measurement interrupted.
12: Torque too high, rotating measurement interrupted.
