SINAMICS G130/G150
1734 List Manual (LH2), 07/2016, A5E03263479A
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
Component: Sensor Module Encoder 1 Propagation: LOCAL
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.
Fault value (r0949, 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: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: Encoder 1 Propagation: LOCAL
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
A31410 (F, N) Encoder 1: Serial communications
Message value: Fault cause: %1 bin
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: Encoder 1 Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: Serial communication protocol transfer error between the encoder and evaluation module.
Alarm value (r2124, interpret binary):
Bit 0: Alarm bit in the position protocol.
Bit 1: Incorrect quiescent level on the data line.
Bit 2: Encoder does not respond (does not supply a start bit within 50 ms).
Bit 3: CRC error: The checksum in the protocol from the encoder does not match the data.
Bit 4: Encoder acknowledgment error: The encoder incorrectly understood the task (request) or cannot execute it.
Bit 5: Internal error in the serial driver: An illegal mode command was requested.
