Channel %1 block %3 spindle %2 maximum speed for encoder resyn-
chronization exceeded
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
The limit frequency of the active encoder (axis-specific MD 36 300
ENC_FREQ_LIMIT) has been exceeded for one of the functions G33
(thread cutting with encoder), G95 (revolution feedrate) or G96 (constant
cutting speed). The spindle synchronization got lost as a result of this.
Alarm display.
Interface signals are set.
NC Stop at alarm.
NC Start inhibited.
Check the limit frequency default data specified for this encoder in MD 36 300
ENC_FREQ_LIMIT.
Check the maximum spindle speed in the axis-specific MD 35 130
GREAR_STEP_MAX_VELO_LIMIT and correct (reduce) it if necessary.
Program an upper spindle speed limitation with G26 S.. in the preceding NC
block which must be below the maximum encoder limit frequency.
Press the RESET key to clear the alarm. Restart part program.
Channel %1 block %3 spindle %2 axis stop during tapping
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
The drilling axis has been stopped via the NC/PLC interface during tapping
with compensation chuck (G63) - the spindle continues rotating. The thread
and (in some cases) also the tapping drill have been damaged as a result of this.
Alarm display.
Interface signals are set.
NC Stop at alarm.
NC Start inhibited.
Provide for interlock in NC user program so that no axis stop can be initiated
when tapping is active. If the tapping operation is to be aborted in critical ma-
chine conditions, spindle and axis must be stopped at the same time if possible.
Slight deviations will be compensated by the compensation chuck.
Press the RESET key to clear the alarm. Restart part program.
Channel %1 spindle %2 axis stopped during thread cutting
%1 = Channel number
%2 = Axis name, spindle number
The thread cutting axis has been stopped during an active thread block.
The stop can be caused by VDI signals resulting in feed interruption.
