0: Linear, This pattern can usually be used.
1: S-pattern 1, Select this pattern to accelerate/decelerate the motor rapidly to a high-
speed region with an output frequency of 50Hz or more or to minimize the shocks
applied during acceleration/deceleration. This pattern is suitable for pneumatic
transport machines.
2: S-pattern 2, Select this pattern to obtain slow acceleration in a demagnetizing region
with a small motor acceleration torque. This pattern is suitable for high-speed spindle
operation.
