FS 16i/18i-MA/MB, Improvement of acc./dec. time constant setting before interpolation (AI contour control, AI nano contour control, Advanced preview control) Supplement to Manual Page 4

Supplement to Manual
1787
Time constant for bell-shaped acceleration/deceleration of acceleration time fixed type before
look-ahead interpolation (For rotary axis)
[Data type] Byte
[Data unit] 1 ms
[Data range] 0 to 255
This parameter is used to set a time constant for bell-shaped acceleration/deceleration
before look-ahead interpolation during AI contour control and AI nano contour
control mode. (For rotary axis)
The time constant, which is set in this parameter, is available to the command
including the rotary axis. (The time constant, which is set in the parameter No.1772,
is available to the command excluding the rotary axis.)
Note
1. The option of “bell-type acceleration/deceleration before look ahead
interpolation” is necessary.
2. This parameter is effective only when the value excluding ‘0’ is set to the
parameter No.1786.
