27110 Axis %1 fault during data transmission index%2.
Parameters: %1 = Axis number
%2 = Index in data cross-check.
Definitions: Faulty communication between NCK and drive caused that data cross-check
of data and indicated index could not be executed three times in a row.
Reaction: Alarm display.
In addition, a Stop F is triggered that may cause follow-up alarm 27001 with error code 0 as well as
alarms 27023 and 27024.
Alarm 27001 with error code 0 can be avoided by alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL higher or equal to 1).
Remedy: Verification of compliance with the EMC regulations.
Replace the hardware.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27111 Axis %1 fault during encoder evaluation of the safe actual value.
Parameters: %1 = Axis number
Definitions: The redundantly determined safe actual value does not match
the fine resolution actual value of the same encoder.
Reaction: Alarm display.
In addition, a Stop F is triggered that may cause follow-up alarm 27001 with error code 0 as well as
alarms 27023 and 27024.
Alarm 27001 with error code 0 can be avoided by alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL higher or equal to 1).
Remedy: Verification of compliance with the EMC regulations.
Replace the hardware.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27112 Axis %1 CRC error of the safe actual value.
Parameters: %1 = Axis number
Definitions: An error has been detected on verifying data consistency of the safe actual value (CRC).
Reaction: Alarm display.
In addition, a Stop F is triggered that may cause follow-up alarm 27001 with error code 0 as well as
alarms 27023 and 27024.
Alarm 27001 with error code 0 can be avoided by alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL higher or equal to 1).
Remedy: Possible causes of the continual presence of this alarm:
- The NCK monitoring channel for safe motion monitoring is not communicating with the monitoring
channel of the assigned drive but with that of another axis. Check the correctness of the assignment
of the drive in the hardware configuration, $MA_SAFE_CTRLOUT_MODULE_NR,
$MN_SAFE_DRIVE_LOGIC_ADDRESS, and p0978.
- Interference in the communication between NCK and drive. Check compliance with the EMC
guidelines. Exchange hardware.
Program Clear alarm with the RESET key. Restart part program
