Overview of Alarms
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Evaluation of the drive alarms listed above.
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
25202
Axis %1 waiting for drive
Parameters: %1 = Axis name, spindle number
Definitions: Drive group error (self-clearing).
Reactions: - Interface signals are set.
- Alarm display.
Remedy: 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.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
26000
Axis %1 clamping monitoring
Parameters: %1 = Axis name, spindle number
Definitions: 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).
Reactions: - Mode group not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Determine the position deviation to the setpoint position and, depending on the results,
either increase the permissible tolerance in the MD or mechanically improve the clamping
(e.g. increase clamping pressure).
Program Con- Clear alarm with the RESET key in all channels of this mode group. Restart part program.
tinuation:
26001
Axis %1 parameterization error: friction compensation
Parameters: %1 = Axis name, spindle number
Definitions: The parameterization of the adaptation characteristic in the quadrant error compensation
is not allowed because acceleration value 2 (MD 32560 FRICT_COMP_ACCEL2 is not
between acceleration value 1 (MD 32550 FRICT_COMP_ACCEL1) and acceleration
value 3 (MD 32570 FRICT_COMP_ACCEL3).
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
Reactions: - Mode group not ready.
- The NC switches to follow-up mode.
