Switching Frequency
Sets the frequency for automatic acceleration/
deceleration switching.

<3>
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.
