F33150 (N, A) Encoder 3: Initialization error
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.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A33400 (F, N) Encoder 3: Alarm threshold zero mark distance error
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.
Reaction upon F: A_INFEED: NONE (OFF1, OFF2)
SERVO: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: NONE (IASC / DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
A33401 (F, N) Encoder 3: Alarm threshold zero marked failed
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The 1.5 x parameterized zero mark distance was exceeded.
The zero mark distance for the zero mark monitoring is set in p0425 (rotary encoder) or p0424 (linear encoder).
Alarm value (r2124, interpret decimal):
Number of increments after POWER ON or since the last zero mark that was detected (4 increments = 1 encoder
pulse).
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 clearance between zero marks (p0425).
- replace the encoder or encoder cable.
