Overview of Alarms
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22150
Channel %1 block %3 spindle %2 maximum speed for position control exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The maximum encoder speed was exceeded with SPCON. Position control is no longer
possible. The NC reduces the setpoint speed with the above functions until the active
encoder is able to measure again. The alarm is issued if the encoder still reports the fault.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Program speed limit with G26.
• Reduce the maximum speed in the appropriate machine data.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22200
Channel %1 spindle %2 axis stopped during tapping
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: When tapping with compensating chuck (G63) the drilling axis was stopped via the
NC/PLC interface and the spindle continues to rotate. The thread and possibly also the
tap were damaged as a result.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Please inform the authorized personnel/service department. Provide an interlock in the
PLC user program so that no axis stop can be initiated when tapping is active. If the tap-
ping operation is to be terminated under critical machine conditions, the spindle and the
axis should be stopped simultaneously if at all possible. Slight differences are then
accommodated by the compensating chuck.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22250
Channel %1 spindle %2 axis stopped during thread cutting
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The thread cutting axis has been stopped while a thread block was active.
The stop can be caused by VDI signals that cause the feed to be interrupted.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Please inform the authorized personnel/service department. Check the axis-specific/spin-
dle-specific stop signals (DB 31 - 48, DBX 4.3).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22260
Channel %1 spindle %2 thread might be damaged
Parameters: %1 = Channel number
%2 = Axis name
