4.2 List of faults and alarms
F07986 Drive: Rotating measurement ramp-function generator
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: During the rotating measurements, problems with the ramp-function generator occurred.
Fault value (r0949, interpret decimal):
1: The positive and negative directions are inhibited.
Remedy: For fault value = 1:
Enable the direction (p1110 or p1111).
A07987 Drive: Rotating measurement, no encoder available
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: No encoder available. The rotating measurement was carried out without encoder.
Remedy: Connect encoder or select p1960 = 1, 3.
F07988 Drive: Rotating measurement, no configuration selected
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: When configuring the rotating measurement (p1959), no function was selected.
Remedy: Select at least one function for automatic optimization of the speed controller (p1959).

F07989 Drive: Rotating measurement leakage inductance (q-axis)
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: An error has occurred while measuring the dynamic leakage inductance.
Fault value (r0949, interpret decimal):
1: The speed did not reach a steady-state condition.
2: The speed setpoint was not able to be approached as the minimum limiting is active.
3: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
4: The speed setpoint was not able to be approached as the maximum limiting is active.
5: The 100% flux setpoint was not reached.
6: No Lq measurement possible because field weakening is active.
7: Speed actual value exceeds the maximum speed p1082 or 75% of the rated motor speed.
8: Speed actual value is below 2 % of the rated motor speed.
Remedy: For fault value = 1:
- check the motor parameters.
- carry out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 25 %).
