Alarm display.
Remedy: Please inform the authorized personnel/service department. Check and correct the characteristic data in the
compensation table ($AN_CEC_OUTPUT_AXIS and $AN_CEC_MULT_BY_TABLE).
If the error cannot be found, the alarm can be suppressed by switching off the compensation in the axis
($MA_CEC_ENABLE) or the tables, ($SN_CEC_TABLE_ENABLE).
Program Clear alarm with the RESET key. Restart part program
Continuation:
20124 Axis %1: sum of compensation values too large
Parameters: %1 = Axis name, spindle number
Definitions: The sum of the compensation values from all tables assigned to the axis had exceeded the limit value MD32720
$MA_CEC_MAX_SUM and had to be limited. Contour errors could have occurred as a result.
Reaction: Interface signals are set.
Alarm display.
Remedy: Check characteristic data of the compensation tables assigned to the axis.
Check characteristic curves in the tables ($AN_CEC).
Program Clear alarm with the RESET key. Restart part program
Continuation:
20125 Axis %1: change of compensation value is too rapid
Parameters: %1 = Axis name, spindle number
Definitions: The compensation value has changed more rapidly than has been allowed for in MD32730 $MA_CEC_MAX_VELO.
It had to be limited temporarily. The missing section is repeated later but contour errors might have occurred.
Reaction: Interface signals are set.
Alarm display.
Remedy: Check characteristic data of the compensation tables assigned to the axis.
Check characteristic curves in the tables ($AN_CEC). Possibly one of the input axes has moved more rapidly than
provided for.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20138 [Channel %1: ] Block %2 motion synchronous action %3 command axis %4 cannot be
traversed
Parameters: %1 = Channel number
%2 = Block number, line number
%3 = Synact ID
%4 = Axis name
Definitions: An NC alarm was detected for a command axis which is to be traversed from a synchronous action.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20139 [Channel %1: ] Block %2 motion synchronous action: %3 invalid marker
Parameters: %1 = Channel number
%2 = Block number, line number
%3 = Synact ID
Definitions: Setting or deleting of a marker in the motion-synchronous action is not possible.
Possible causes:
SETM(): Maximum number of markers exceeded; marker has already been set.
CLEARM(): Specified marker is not within permissible value range.
Reaction: NC Start disable in this channel.
