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.
Reaction upon F: Vector: NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
F31405 (N, A) Encoder 1: Temperature in the encoder evaluation inadmissible
Message value: %1
Message class: Overtemperature of the electronic components (6)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: ENCODER (IASC/DCBRK, NONE, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The encoder evaluation for a motor with DRIVE-CLiQ has detected an inadmissible temperature.
The fault threshold is 125 ° C.
Alarm value (r2124, interpret decimal):
Measured board/module temperature in 0.1 °C.
Remedy: Reduce the ambient temperature for the DRIVE-CLiQ connection of the motor.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A31407 (F, N) Encoder 1: Function limit reached
Message value: %1
Message class: Position/speed actual value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The encoder has reached one of its function limits. A service is recommended.
Alarm value (r2124, interpret decimal):
1 : Incremental signals
3 : Absolute track
4 : Code connection
Remedy: Perform service. Replace the encoder if necessary.
Note:
The actual functional reserve of an encoder can be displayed via r4651.

Reaction upon F: Vector: NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
