3.2.1

General information

Measuring cycle user programs CYCLE198 and CYCLE199 are called in the measuring
cycles and can be used to program necessary adjustments before or after a measurement
(e.g. activate probe, position spindle).
3.2.2

CYCLE198: User program before undertaking measurement

Function
CYCLE198 is called at the beginning of each measuring cycle.
It can be used to program actions necessary before starting a measurement (e.g. activate
probe).
In the as-delivered state, this cycle only contains one CASE statement that executes a jump
to a label with subsequent M17 (end of subroutine) for each measuring cycle.
Example
_M977:
M17
From this label all actions to be executed on each CYCLE977 call must be programmed.
3.2.3

CYCLE199: User program after undertaking measurement

Function
CYCLE199 is called in each measuring cycle when measurement is complete. It can be
used to program actions necessary following completion of a measurement
(e.g. deactivate probe).
The internal structure of the cycle is the same as that of CYCLE198, i.e. the program lines
must be inserted between the label for a particular cycle and M17 (end of subroutine).
