Accel/Decel Time Switching
Frequency
Sets the frequency for automatic acceleration/deceleration
switching.
Below set frequency: Accel/Decel Time 4
Above set frequency: Accel/Decel Time 1
The multi-function input “Accel/Decel Time 1” or “Accel/
Decel Time 2” take priority.

Accel/Decel Rate
Frequency
Sets the base frequency used to calculate acceleration and
deceleration times.
When set to 0.0 Hz, the drive calculates the time required
to accelerate from 0 Hz to E1-04, and decelerate from E1-04
down to 0 Hz (conventional setting).
When set to any other value above 0.0 Hz, the drive
calculates the time required to accelerate from 0 Hz to
C1-14, and to decelerate from C1-14 down to 0 Hz.
