4 Faults and alarms
4.2 List of faults and alarms
Remedy: - determine the detailed cause of the fault using the fault value.
- replace the encoder if necessary.
Note:
An EnDat 2.2 encoder may only be removed and inserted in the "Park" state.
If an EnDat 2.2 encoder was removed when not in the "Park" state, then after inserting the encoder, a POWER ON
(switch-off/switch-on) is necessary to acknowledge the fault.
F32137 Encoder 2: Internal fault when determining the position
Message class: Hardware/software error (1)
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
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) error position word 1.
Bit 9: F2 (safety status display) error 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.
F32138 Encoder 2: Internal error when determining multiturn information
Message class: Hardware/software error (1)
Reaction: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3)
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) error position word 1.
Bit 9: F2 (safety status display) error 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.
F32142 (N, A) Encoder 2: Battery voltage fault
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF1 (IASC/DCBRK, NONE, 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.
