■Acceleration/deceleration patterns

1)Linear acceleration/deceleration

Ageneral acceleration/ deceleration pat- tern. This pattern can usually be used.

2)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.

3)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.
