4 Faults and alarms
4.2 List of faults and alarms
Remedy: - track C or D not connected.
- correct the direction of rotation of the Hall sensor possibly connected as equivalent for track C/D.
- check that the encoder cables are routed in compliance with EMC.
- check the adjustment of the Hall sensor.

F31130 (N, A) Encoder 1: Zero mark and position error from the coarse synchronization
Message value: Angular deviation, electrical: %1, angle, mechanical: %2
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: Encoder 1
Reaction: Vector: ENCODER (IASC/DCBRK, NONE, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE
Acknowledge: PULSE INHIBIT
Cause: After initializing the pole position using track C/D, Hall signals or pole position identification routine, the zero mark
was detected outside the permissible range. For distance-coded encoders, the test is carried out after passing 2 zero
marks. Fine synchronization was not carried out.
When initializing via track C/D (p0404) then it is checked whether the zero mark occurs in an angular range of +/-18 °
mechanical.
When initializing via Hall sensors (p0404) or pole position identification (p1982) it is checked whether the zero mark
occurs in an angular range of +/-60 ° electrical.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex
yyyy: Determined mechanical zero mark position (can only be used for track C/D).
xxxx: Deviation of the zero mark from the expected position as electrical angle.
Scaling: 32768 dec = 180 °

Remedy: - check p0431 and, if necessary, correct (trigger via p1990 = 1 if necessary).
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- if the Hall sensor is used as an equivalent for track C/D, check the connection.
- check the connection of track C or D.
- replace the encoder or encoder cable.

F31131 (N, A) Encoder 1: Deviation position incremental/absolute too large
Message value: %1
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: Encoder 1
Reaction: Vector: ENCODER (IASC/DCBRK, NONE, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE
Acknowledge: PULSE INHIBIT
Cause: Absolute encoder:
When cyclically reading the absolute position, an excessively high difference to the incremental position was
detected. The absolute position that was read is rejected.
Limit value for the deviation:
- EnDat encoder: Is supplied from the encoder and is a minimum of 2 quadrants (e.g. EQI 1325 > 2 quadrants, EQN
1325 > 50 quadrants).
- other encoders: 15 pulses = 60 quadrants.
