ii) Constant-acceleration-time (parameter No. 1603#4 RPTCT = 1):
In the case that the time constants(parameter No.1620) for X and Y axes are the same.
Deviation of actual positioning path from the programmed path is smaller than that by
constant-acceleration-rate acceleration/deceleration after interpolation.
As a result, positioning is performed more exactly along the programmed path by
constant-acceleration-time acceleration/deceleration (parameter No. 1603#4 RPTCT = 1).

RPTCT
Acceleration/deceleration for Linear-type Positioning is performed in:
0: Constant-acceleration-rate manner
1: Constant-acceleration-time manner.
[Note]
In constant-acceleration-time setting, the data range of the parameter No.1620(Time
constant of linear acceleration/deceleration in rapid traverse for each axis) is from 0 to
4096 in total for all axes.
