Axis %1 drive fault
%1 = Axis name, spindle number
The drive signals a serious fault of status class 1 (ZK1). The exact cause of the fault can
be recognized by evaluating the following drive alarms which are output in addition:
Alarm 300 500, alarms 300 502 - 300 505, alarm 300 508, alarm 300 515, alarm 300 608,
alarm 300 612, alarm 300 614, alarms 300 701 - 300 761, alarm 300 799.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
Evaluation of the drive alarms listed above.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 waiting for drive
%1 = Axis name, spindle number
Drive group error (self-clearing).
- Alarm display.
- Interface signals are set.
Wait for the drive. 25202 reveals similar problems to alarm 25201 (see this alarm). The
alarm is active continuously during power-up if the drive does not communicate (e.g.
Profibus connector removed). Otherwise, the alarm is active only briefly and is replaced
by alarm 25201 after an internal timeout in the event of a permanent problem.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 clamping monitoring
%1 = Axis name, spindle number
The clamped axis is to be pushed out of its setpoint position. The permissible difference is
defined in the axis-specific machine data 36050 CLAMP_POS_TOL.
Clamping of an axis is activated with the axis-specific interface signal DB 31 - 48, DBX
2.3: "Clamping process active".
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
- Channel not ready.
- NC Start disable in this channel.
- NC Stop on alarm.
- The NC switches to follow-up mode.
- Alarm display.
- Interface signals are set.
