FUN-72: Accel/Decel Change Frequency
This function is used to change Accel/Decel ramps at a
certain frequency. The drive will ramp the speed to
FUN-72 using I/O-50 (Acceleration Time1). At that
point it will switch to DRV-01 (Acceleration Time).
Likewise, upon deceleration, the drive will use DRV-
02 (Deceleration Time) until the drive reaches FUN-72,
where it will switch to I/O-51 (Deceleration Time 1).
Note: If Accel/Decel change frequency is set and
‘XCEL-L’, XCEL-M’, and XCEL-H’ defined in
multi-function terminals are ON, Multi Accel/Decel
operation has the priority.

FUN-73: Reference Frequency for Accel/Decel
This parameter determines the reference for the Accel /
Decel times. For most applications, the Max freq.
setting is appropriate.
