Program Clear alarm with the Delete key or NC START.
Continuation:
22024 [Channel %1: ] Block %2 Spindle %3 tapping: PLC signal 'invert M3/M4' changed after
%4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle
%4 = Value
Definitions: When loading a G331 block it was detected that the NC/PLC interface signal <M3M4_invertieren/> (invert M3/M4) had
changed during part program execution. An alarm was output to prevent a tool break. The current value of the NC/
PLC interface signal is displayed as parameter 4.
Reaction: Channel not ready.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: A change in the NC/PLC interface signal <M3M4_invertieren/> (invert M3/M4) during part program execution should
be avoided.
If MD35035 SPIND_FUNCTION_MASK bit 22 is set, the NC/PLC interface signal <M3M4_invertieren/> (invert M3/
M4) is then no longer evaluated during tapping with G331, G332. The alarm is no longer output. Notice! Setting bit 22
means a change in function.
Program Clear alarm with the RESET key. Restart part program
Continuation:
22025 [Channel %1: ] Block %2 Following axis/spindle %3 synchronism (2): Fine tolerance
overshot
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following axis/spindle number
Definitions: Synchronism is monitored once the 'FINE' block-change criterion has been met. The 'fine' threshold value defined with
MD37212 $MA_COUPLE_POS_TOL_FINE_2 has been exceeded by the synchronism difference on the actual value
side. The alarm can be suppressed with MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 12 = 1 or with CP pro-
gramming by setting CPMALARM[FAx] bit 8 = 1.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department.
The following axis/spindle was not able to follow the leading axis(axes)/spindle(s).
Program Clear alarm with the Delete key or NC START.
Continuation:
22026 [Channel %1: ] Block %2 Following axis/spindle %3 synchronism(2): Coarse tolerance
overshot
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Following axis/spindle number
Definitions: Synchronism is monitored once the 'COARSE' block-change criterion has been met. The 'coarse' threshold value
defined with MMD37202 $MA_COUPLE_POS_TOL_COARSE_2 has been exceeded by the synchronism difference
on the actual value side. The alarm can be suppressed with MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 12 =
1 or with CP programming by setting CPMALARM[FAx] bit 9 = 1.
Reaction: Alarm display.
