F33130 (N, A) Encoder 3: Zero mark and position error from the coarse synchronization
Message value:
Angular deviation, electrical: %1, angle, mechanical: %2
Drive object:
All objects
Reaction:
Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, 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 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 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: Position deviation incremental/absolute too high
Message value:
%1
Drive object:
All objects
Reaction:
Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3, 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.
Incremental encoder:
When the zero pulse is passed, a deviation in the incremental position was detected.
For equidistant zero marks, the following applies:
- the first zero mark passed supplies the reference point for all subsequent checks. The other zero marks must have n
times the distance referred to the first zero mark.
For distance-coded zero marks, the following applies:
- the first zero mark pair supplies the reference point for all subsequent checks. The other zero mark pairs must have the
expected distance to the first zero mark pair.
Fault value (r0949, interpret decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
