3 Calling OEM Cycles

9-9

3.2 Calls in an ISO program

In an ISO program, OEM cycles are not called via a G- function but via key "D" and the cycle number
(e.g. D88).

The individual parameters are input via the numeric keyboard and entered with ENT.

In the case of a "DEF-active" OEM-cycle, the cycle is effective immediately after definition. Once
defined, a "CALL-active" OEM-cycle can be called and hence activated either via G79 or M99.
