Time constant for linear acceleration/deceleration after cutting feed interpolation
during advanced preview control mode.
[Data type] Word
[Unit of data] ms
[Valid data range] 8 to 512
This parameter sets a time constant for linear acceleration/deceleration
after cutting feed interpolation in the advanced preview control mode.
Use parameter LS2 (No.1602#6) to select the acceleration/deceleration
type.
1770 Parameter 1 (for advanced preview control) for setting an acceleration for lin-
ear acceleration/deceleration before interpolation (maximum machining speed
during linear acceleration/deceleration before interpolation)

Inch machine 0.1 inch/min 6 to 96000 6 to 48000
This parameter is used to set an acceleration for linear acceleration/
deceleration before interpolation in the advanced preview control mode.
In this parameter, set the maximum machining speed during linear
acceleration/ deceleration before interpolation. Set the time used to reach
the maximummachining speed in parameter No.1771.
