* The setting range for acceleration/deceleration times depends on the setting of C1-10 (Acceleration/deceleration Time Setting Unit). If C1-10 is set to 0,
the setting range is 0.00 to 600.00 (s).
S-curve Acceleration/Deceleration: C2
User constants for S-curve characteristics are shown in the following table.

S-curve
characteris-

accelera-
tion start
All sections of the S-curve characteris-
tic time are set in seconds units.
When the S-curve characteristic time is
set, the accel/decel times will increase
by only half of the S-curve characteris-
tic times at start and end.
