Retraction While Thread Cutting; Rapid Lift Using Asub And Fast Input - Siemens SINUMERIK 840D sl Function Manual

R3: Extended stop and retract
9.5 Examples
Trigger conditions and static synchronized actions
Example 1:
Trigger condition is the occurrence of alarms, which activate the follow-up (tracking) mode:
Program code
IDS=02 WHENEVER ($AC_ALARM_STAT B_AND 'H2000') > 0 DO $AC_ESR_TRIGGER=1
Example 2
Trigger condition is when the ELG synchronous monitoring responds, if, e.g. Y is defined as
ELG following axis and the max. permissible synchronism difference is 100 mm:
Program code
IDS=03 WHENEVER $VA_EG_SYNCDIFF[Y] > 0.1 DO $AC_ESR_TRIGGER=1

Retraction while thread cutting

During thread cutting, for a fault/interruption, axis X should be retracted to the position specified
under POLF as response. Axis Z continues to traverse until it is stopped as normal.
