SINAMICS-Alarms
233150 <location>Encoder 3: Initialization error
Message %1
value:
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: Encoder functionality selected in p0404 is not operating correctly.
Fault value (r0949, interpret hexadecimal):
The fault value is a bit field. Every set bit indicates functionality that is faulted.
The bit assignment corresponds to that of p0404 (e.g. bit 5 set: Error track C/D).
Remedy: - Check that p0404 is correctly set.
- check the encoder type used (incremental/absolute value) and for SMCxx, the encoder cable.
- if relevant, note additional fault/error messages that describe the fault in detail.
233151 <location>Encoder 3: Encoder speed for initialization AB too high
Message %1
value:
Drive object: All objects
Reaction: A_INFEED: NONE
SERVO: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: PULSE INHIBIT
Cause: The encoder speed is too high during while initializing the sensor.
Remedy: Reduce the speed of the encoder accordingly during initialization.
If necessary, deactivate monitoring (p0437.29).

233400 <location>Encoder 3: Alarm threshold zero mark distance error
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The measured zero mark distance does not correspond to the parameterized zero mark distance.
For distance-coded encoders, the zero mark distance is determined from zero marks detected pairs.
This means that if a zero mark is missing, depending on the pair generation, this cannot result in a
fault and also has no effect in the system.
The zero mark distance for the zero mark monitoring is set in p0425 (rotary encoder) or p0424 (linear
encoder).
Alarm value (r2124, interpret decimal):
Last measured zero mark distance in increments (4 increments = 1 encoder pulse).
The sign designates the direction of motion when detecting the zero mark distance.
Remedy: - check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
. check the encoder type (encoder with equidistant zero marks).
- adapt the parameter for the distance between zero marks (p0424, p0425).
- replace the encoder or encoder cable.
233401 <location>Encoder 3: Alarm threshold zero marked failed
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
