Linear acceleration/deceleration
A general acceleration/ deceleration pat-
tern. This pattern can usually be used.
S-pattern acceleration/deceleration 1
Select this pattern to accelerate/decelerate
the motor rapidly to a high-speed region
with an output frequency of 60Hz or more
or to minimize the shocks applied during
acceleration/deceleration. This pattern is
suitable for pneumatic transport machines.
S-pattern acceleration/deceleration 2
Select this pattern to obtain slow accelera-
tion in a demagnetizing region with a small
motor acceleration torque. This pattern is
suitable for high-speed spindle operation.
