232501 <location>Encoder 2: Position tracking encoder position outside tolerance window
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: When powered down, the drive/encoder was moved through a distance greater than was parameterized in the toler-
ance window. It is possible that there is no longer any reference between the mechanical system and encoder.
Fault value (r0949, decimal):
Deviation (difference) to the last encoder position in increments of the absolute value.
The sign designates the traversing direction.
Note:
The deviation (difference) found is also displayed in r0477.
See also: p0413 (Measuring gear, position tracking tolerance window), r0477 (Measuring gear, position difference)
Remedy: Reset the position tracking as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and, if necessary, the absolute encoder adjusted (p2507).

232502 <location>Encoder 2: Encoder with measuring gear, without valid signals
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The encoder with measuring gear no longer provides any valid signals.
Remedy: It must be ensured that all of the encoders, with mounted measuring gear, provide valid actual values in operation.
232503 <location>Encoder 2: Position tracking cannot be reset
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The position tracking for the measuring gear cannot be reset.
Remedy: The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
