For an axis with 0 set in this parameter, the maximum allowable
acceleration change rate set in parameter No. 1788 is valid.
Feedrate control based on acceleration change is disabled for an axis
with 0 set in parameter No. 1788, so that the setting of this parameter
for such an axis is ignored.

Ratio of change time of the rate of change of acceleration in smooth
bell-shaped acceleration/deceleration before interpolation
[Input type] Parameter input
[Data type] Byte path
[Unit of data] %
[Valid data range] 0 to 50
Set the ratio of the change time of the rate of change of acceleration to
the change time of acceleration(*1) by percentage (%) in smooth
bell-shaped acceleration/deceleration before look-ahead interpolation.
If 0 is set in this parameter or a value not within the valid data range is
specified in this parameter, smooth bell-shaped acceleration/
deceleration before look-ahead interpolation is not performed.
(*1)
Parameter No. 1772 for acceleration/deceleration before look-ahead
interpolation (cutting feed).
Parameter No. 1672 for acceleration/deceleration before interpolation
in linear rapid traverse, or for optimum torque acceleration/
deceleration.

# 1 DC4x When the reference position is established on the linear scale with
reference marks:
0: An absolute position is established by detecting three reference
marks.
1: An absolute position is established by detecting four reference
marks.
# 2 DC2x Reference position establishment operation for a linear scale with
reference marks is performed as follows:
0: The setting of bit 1 (DC4) of parameter No. 1802 is followed.
1: An absolute position is established by detecting two
reference marks.
