4.2 List of faults and alarms
F32129 (N, A)
Encoder 2: Position difference hall sensor/track C/D and A/B too large
Message class:
Actual position/speed value incorrect or not available (11)
Reaction:
OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
Acknowledge:
PULSE INHIBIT
Cause:
The error for track C/D is greater than +/-15 ° mechanical or +/-60 ° electrical or the error for the Hall signals is
greater than +/-60 ° electrical.
One period of track C/D corresponds to 360 ° mechanical.
One period of the Hall signal corresponds to 360 ° electrical.
The monitoring responds if, for example, Hall sensors are connected as equivalent for the C/D tracks with the
incorrect rotational sense or supply values that are not accurate enough.
After the fine synchronization using one reference mark or 2 reference marks for distance-coded encoders, this fault
is no longer initiated, but instead, Alarm A32429.
Fault value (r0949, interpret decimal):
For track C/D, the following applies:
Measured deviation as mechanical angle (16 bits with sign, 182 dec corresponds to 1 °).
For Hall signals, the following applies:
Measured deviation as electrical angle (16 bits with sign, 182 dec corresponds to 1 °).
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.
F32130 (N, A)
Encoder 2: Zero mark and position error from the coarse synchronization
Message class:
Actual position/speed value incorrect or not available (11)
Reaction:
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.
F32131 (N, A)
Encoder 2: Deviation position incremental/absolute too large
Message class:
Actual position/speed value incorrect or not available (11)
Reaction:
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.
