Block %3 Spindle %2 Chuck Speed Exceeded; Spindle %2 Axis Stopped During Tapping; Spindle %2 Axis Stopped During Thread Cutting - Siemens Sinamics S120 Diagnostic Manual

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 MD35100 $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 MD11412 $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 actu-
ator in accordance with the Installation and Start-up Guide and make corrections.
Increase the tolerance window in MD35150 $MA_SPIND_DES_VELO_TOL.

Continuation:
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.
Reaction: 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 tapping 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 Clear alarm with the RESET key. Restart part program
Continuation:
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.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Check the axis-specific/spindle-specific stop DB380x
DBX0004.3 (Spindle stop).
Program Clear alarm with the RESET key. Restart part program
