Overview of Alarms
NCK alarms
22100 Channel %1 block %3 spindle %2 chuck speed exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The actual spindle speed is higher than the maximum speed configured in machine data 35100
$MA_SPIND_VELO_LIMIT plus a tolerance of 10 percent (fixed setting).
The alarm should not occur after correct optimization of the drive actuator and gear configuration.
This alarm can be reconfigured with MD 11412 $MN_ALARM_REACTION_CHAN_NOREADY
(channel not ready to operate) to 'BAG not ready'.
Note: Reconfiguring affects all alarms with alarm response 'Chan not ready'.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check the setup and optimization data of
the drive actuator in accordance with the Installation and Start-up Guide and make corrections.
Increase the tolerance window in machine data 35150 SPIND_DES_VELO_TOL.
Program Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
22101 Channel %1 block %3 spindle %2 maximum speed for encoder
resynchronization exceeded
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: The maximum encoder speed was exceeded with G33, G95, G96 or G97. Reference to actual speed
and actual position 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.
Reaction: 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 Clear alarm with the RESET key. Restart part program
Continuation:
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.
Reaction: 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 Clear alarm with the RESET key. Restart part program
