Adaptive Feed & Depth Parameters
Chapter 32

Function
The feedrate Acc/Dec Enable parameter is used to enable Acc/Dec for an
axis that is in adaptive feed mode. Adaptive feed mode is used to cause the
servo to maintain a constant torque while cutting by varying the axis
feedrate. Refer to your 9/Series Mill Operation and Programming Manual
for details on this feature. This parameter is only available on mill control
types.
Acc/Dec on an adaptive feed axis is used to smooth out the shock that
could occur to an axis from the rapid application of increasing/decreasing
torque by the servo.
If you select: it:
enable causes the programmed torque to be ramped as the control ramps the feedrate
using linear Acc/Dec. On shorter moves, that do not extend beyond the Acc/Dec
ramps, the programmed torque may never be reached by the servo. This
Acc/Dec ramping is applied over top of the control’s already modified feedrate
command being used to obtain the programmed torque.
disable causes the control to issue non-accelerate/decelerated feedrate commands and
may in some cases cause rough or choppy machine motion as sudden
acceleration or deceleration occurs.
