Set speed difference for the speed difference–based automatic corner
deceleration function when linear acceleration/deceleration after
interpolation used.

Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotation axis 0.1 deg/min 6 to 15000 6 to 12000
A separate allowable feedrate difference can be set for each axis. The
allowable feedrate difference is set for each axis with this parameter.
Among the axes that exeed the specified allowable feedrate difference, the
axis with the greatest ratio of the actual feedrate difference to the
allowable feedrate difference is used as the reference to calculate the
reduced feedrate at the corner.

before interpolation

Deceleration is started beforehand to reach the feedrate set in the
parameter when an overtravel alarm is issued (when a limit is reached)
during linear acceleration/deceleration before interpolation. By using
this parameter, the overrun distance that occurs when an overtravel alarm
is output can be reduced.
