Bit 17: Fault in the multiturn.
Bit 23: Temperature outside the limit values.
Note:
For an encoder version that is not described here, please contact the encoder manufacturer for more detailed
information on the bit coding.
Remedy: - determine the detailed cause of the fault using the fault value.
- if required, replace the DRIVE-CLiQ encoder.
F31138 Encoder 1: Internal error when determining multiturn information
Message value: Fault cause: %1 bin
Message class: Hardware / software error (1)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: ENCODER (IASC/DCBRK, NONE)
Infeed: NONE
Acknowledge: PULSE INHIBIT
Cause: A position determination fault has occurred in the DRIVE-CLiQ encoder.
Fault value (r0949, interpret binary):
yyxxxxxx hex: yy = encoder version, xxxxxx = bit coding of the fault cause
For yy = 08 hex (bit 27 = 1), the following bit definition applies:
Bit 1: Signal monitoring (sin/cos).
Bit 8: F1 (safety status display) fault position word 1.
Bit 9: F2 (safety status display) fault position word 2.
Bit 16: LED monitoring iC-LG (opto ASIC).
Bit 17: Fault in the multiturn.
Bit 23: Temperature outside the limit values.
Note:
For an encoder version that is not described here, please contact the encoder manufacturer for more detailed
information on the bit coding.
Remedy: - determine the detailed cause of the fault using the fault value.
- if required, replace the DRIVE-CLiQ encoder.
F31142 (N, A) Encoder 1: Battery voltage fault
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: ENCODER (IASC/DCBRK, NONE, OFF1, OFF2, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: When switched-off, the encoder uses a battery to back up the multiturn information. The battery voltage is no longer
sufficient to check the multiturn information.
Remedy: Replace battery.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F31150 (N, A) Encoder 1: Initialization error
Message value: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: ENCODER (IASC/DCBRK, NONE, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE
Acknowledge: PULSE INHIBIT
Cause: Encoder functionality selected in p0404 is not operating correctly.
