For further diagnostics, the drive machine data 1391, 1392 and the servo trace signals
"Result list 2, NCK" and "Result list 2, drive" can be used.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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.
Reactions: - 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
($MA_SAFE_ALARM_SUPPRESS_LEVEL higher or equal to 1).
Remedy: Verification of compliance with the EMC regulations.
Replace the hardware.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27111
Axis %1 fault during encoder evaluation of the safe actual value.
Parameters: %1 = Axis number
Definitions: The redundantly determined safe actual value does not match
the fine resolution actual value of the same encoder.
Reactions: - Alarm display.
In addition, a Stop F is triggered that may cause follow-up alarm 27001 with error code 0
as well as
alarms 27023 and 27024.
Alarm 27001 with error code 0 can be avoided by alarm reduction
($MA_SAFE_ALARM_SUPPRESS_LEVEL higher or equal to 1).
Remedy: Verification of compliance with the EMC regulations.
Replace the hardware.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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).
Reactions: - 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.
