6-7-3 Switching of Acceleration or Deceleration Time with Multi-Speed Step
Example (1) If the multi-speed 3rd speed is engaged and the revolution is accelerating, the enabled
acceleration time is the acceleration time setting for Multispeed-3 [AC-38].
Example (2) If the multi-speed 1st speed is engaged and the revolution is decelerating, the enabled
deceleration time is the deceleration time setting for Multispeed-3 [AC-40] for the multi-speed 3rd
speed that has been engaged until the multi-speed 1st speed is engaged.
Exemplar Operation
If the set frequency is the same, only the acceleration or
deceleration time can be changed.
