3) S-pattern acceleration/deceleration 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.

• Function

These parameters allow you to combine a maximum of 30 operation frequencies, operation time and acceleration/deceleration time (15 combinations of parameters x 2 patterns) for automatic pattern operation by means of the terminal board.

Note:When the function of auto-restart is active, the time spent for speed search is added to the operation time set for pattern operation. Consequently, the effective operation time sometimes becomes shorter than the settled operation time.
