Programm Clear alarm with the RESET key. Restart part program
continuation:
25201 Axis %1 drive fault
Parameters: %1 = Axis name, spindle number
Explanation: For PROFIdrive:
The drive signals a serious fault which prevents the drive from being ready. The exact cause of the fault can be found by
evaluating the additionally output drive alarms (It may be necessary to activate these diagnostic alarms by parameterizing
the MDs DRIVE_FUNCTION_MASK, PROFIBUS_ALARM_ACCESS etc):
Alarms 380500 and 380501 (or the corresponding alarm numbers implemented on the HMI side).
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group not ready.
The NC switches to follow-up mode.
Channel not ready.
NC Start disable in this channel.

NC Stop on alarm.
Channel not ready.
Remedy: Evaluation of the drive alarms listed above.
Programm Restart part program.
continuation:
25202 Axis %1 waiting for drive
Parameters: %1 = Axis name, spindle number
Explanation: Drive group error (self-clearing).
Reaction: Interface signals are set.
Alarm display.
Remedy: For PROFIdrive only:
Wait for the drive. This alarm reveals similar problems to alarm 25201 (see that alarm). It is continuously active during
power-up if the drive does not communicate (e.g. if the PROFIBUS connector has fallen out). Otherwise, the alarm is active
only briefly and is replaced by alarm 25201 after an internal timeout in the event of a permanent problem.
Programm Alarm display showing cause of alarm disappears. No further operator action necessary.
continuation:
25220 Axis %1 gear ratio changed with ESR enabled
