SMC10:
A signal level of 2900 mV peak value corresponds to the numerical value 6666 hex = 26214 dec.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: - check that the encoder cables are routed in compliance with EMC.
- replace the encoder or encoder cable.
- with measuring systems without their own bearing system: Adjust the scanning head and check the bearing system
of the measuring wheel.

F32129 (N, A) Encoder 2: Position difference, hall sensor/track C/D and A/B too large
Drive object: All objects
Reaction: A_INFEED: NONE
SERVO: OFF1 (IASC / DCBRAKE, NONE, OFF2, OFF3)
VECTOR: OFF1 (IASC / DCBRAKE, 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 incor-
rect 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
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 °
