Soft Start
S-curve characteristic time C2-01 to 04
Accel/decel by S-curve pattern can be accomplished to
prevent shock at start, or stop of the machine.
Setting the S-curve characteristic time, the acceleration or deceleration
time will be longer by 1/2 of the S-curve characteristic time at start or end.
