2.3 Acceleration matching (ACC) (axis-specific)
2.3.1 Detailed Description
2.3.1.1 General Information
Function
A part-program instruction (ACC) can be used to match the acceleration of specific axes to
the current machining situation. The range used for this purpose is anywhere between
greater than 0% and less than or equal to 200% of the maximum value programmed in the
machine data.

Acceleration matching is effective for all types of interpolation in AUTOMATIC and
MDA operating modes as well as with dry-run feed.
Acceleration matching is ineffective in JOG and JOG/REF (reference point
approach) operating modes.
Acceleration matching is also ineffective if the machine axes have been brought to a
standstill via a quick stop due to the detection of a fault (setpoint = 0).
