Acceleration or deceleration time table
• The following table shows the multi-speed commands and their corresponding acceleration or deceleration
times.
Setting state Multi-speed command
The frequency after a speed is ON
will be higher than the speed before
that.
To the accelerating state
Mth
speed
Acceleration time for
multi-speed Mth speed
The frequency after a speed is OFF
will be lower than the speed before
that.
To the decelerating state
Nth speed
Deceleration time for
multi-speed Nth speed
!
• The switching timing of frequency command by
multi-speed terminal command is different from
that of the deceleration time.
