Explanation
Lock synchronized action with ID or stop technology cycle
One or more IDs can be programmed
Unlock synchronized action with ID or continue technology
cycle
One or more IDs can be programmed
Reset technology cycle
One or more IDs can be programmed
Each block of a technology cycle is processed in a separate
interpolation cycle following ICYCON
All blocks of a technology cycle are processed in one inter‐
polation cycle following ICYCOF

Explanation
If the condition in the motion-
synchronous action is fulfilled,
the polynomial determined by
the first expression is evaluated
at the input variable. The upper
and lower range of the value is
limited and the result variable is
assigned.
Change of fine tool compensa‐
tion depending on a function de‐
fined with FCTDEF (max. 3rd
degree polynomial).
The number used here must be
specified in FCTDEF.
