2.4 Actions in synchronized actions
Boundary condition
The synchronized action FTOC is available in Software-version 3.2 and later.
An online offset allows an overlaid movement to be implemented for a geometry axis
according to a polynomial programmed with FCTDEF (see Subsection "FCTDEF") as a
function of a reference value (e.g. actual value of an axis).
The coefficient a

All main variables of the type REAL listed in the chapter "List of
system variables relevant for synchronized actions" are
permitted.
Wear parameter into which the tool offset value is added.
Target channel in which the offset must be applied. This
enables simultaneous dressing from a parallel channel. If the
channel number is missing, the offset is effective in the active
channel. Online offset with FTOCON must be activated in the
target channel.
The spindle number is programmed if a non-active grinding
wheel needs to be dressed. "Constant peripheral speed" or
"tool monitoring" must be active for this purpose. If no spindle
number is programmed, then the active tool is compensated.
