User Constant Tables
5-21
* 1. The setting range for acceleration/deceleration times will depends on the setting for C1-10. When C1-10 is set to 0, the setting range for acceleration/
deceleration times becomes 0.00 to 600.00 seconds.
* 2. When C6-01=0, the upper limit is 150.0.
* 3. When C6-01=1, the upper limit is 400.0.

S-curve
character-

at accel-
eration
start
All sections of the S-curve character-
istic 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
characteristic times at start and end.
