Acceleration matching (ACC) (axis-specific)

4.2.4.1

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.
Effective
Effective Acceleration matching is effective for all types of interpolation in AUTOMATIC and
MDA operating modes as well as with dry-run feed.
Ineffective 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).

Functionality
The ACC part-program instruction is used to adjust the maximum acceleration value of a machine axis.
Axis:
• Value range: Axis identifier for the channel's machine axes
Adjustment factor:
• Value range: 0 < adjustment factor ≤ 200
• Unit: Per cent

Reset response
The behavior during channel RESET or M30 can be controlled via MD32320 $MA_DYN_LIMIT_RESET_MASK :
Bit 0: 0 The programmed ACC value is reduced to 100 % with channel RESET/M30 .
Bit 0: 1 The programmed ACC value is retained beyond channel RESET/M30.
