Name Description
Sets the acceleration time to accel-
erate from 0 Hz to the
maximum output frequency.
Sets the deceleration time to decel-
erate from the maximum output fre-
quency to 0 Hz.
Sets the acceleration time when the
multi-function input "accel/decel
time 1" is set to ON.
Sets the deceleration time when the
multi-function input "accel/decel
time 1" is set to ON.
Sets the deceleration time when the
multi-function input "Emergency
(fast) stop" is set to ON.
Sets the frequency for automatic
acceleration/deceleration switching.
If the output frequency is below the
set frequency: Accel/decel time 2
If the output freuquency is above
the set frequency: Accel/decel
time 1
The multi-function input "accel/
decel time 1" or "accel/decel time
2" has priority.
Name Description
When the S-curve characteristic time is
set, the accel time will increase by only
half of the S-curve characteristic times
at start and end.
