*) Explanation: i.e. the axis is within the tolerance range of the control window par.
32-71 REGWMAX / par. 32-72 REGWMIN. As soon as the control window is set, the
axis controller is switched on again.
The instruction ON STATBIT is used to call up a subprogram when bit n of FC 300
status is set. These 32 bits of the FC 300 status consist of the FC 300 status word,
the byte 2 of the internal status (e.g. MOVING) and the bit n of SYNCSTAT.
NB!:
– The subroutine to be called up must be defined within the SUBMAINPROG and
ENDPROG identified program.
– During the execution of a subroutine called by an interrupt NOWAIT is
automatically set to ON.
If a number of interrupts occur simultaneously, the subprogram assigned to the
lowest bit is worked through first. The other interrupts will be processed after-
wards. If, during an interrupt subroutine, the same interrupt occurs (exception:
error interrupt), then it will be ignored and thus lost.
