F33130 (N, A)
Encoder 3: Zero mark and position error from the coarse synchronization
Drive object:
All objects
Reaction:
A_INFEED: NONE
SERVO: OFF1 (IASC / DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
VECTOR: OFF1 (IASC / DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
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 as to 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.
Normalization: 32768 dec = 180 °
Remedy:
- 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.

F33131 (N, A)
Encoder 3: Deviation, position incremental/absolute too large
Drive object:
All objects
Reaction:
A_INFEED: NONE
SERVO: OFF1 (IASC / DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
VECTOR: OFF1 (IASC / DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
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.
Fault value (r0949, interpret decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
Incremental encoder: When the zero pulse is passed, a deviation in the incremental position was detected.
Remedy:
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder or encoder cable.
- check whether the coding disk is dirty or there are strong ambient magnetic fields.
