00 Always ON This function is effective on acceleration, constant
speed, deceleration.
01 Always OFF This function is ineffective on acceleration, constant
speed, deceleration.

On decelerating
OFF
This increases a loss of motor and reduces the energy
regenerated to inverter on decelerating.
Maximum frequency
Set the maximum frequency value of the inverter.
This set value is the maximum frequncey that the inverter will achieve when
It receives top speed reference from the control terminals or the digital operator.

maximum frequency, set an intelligent input terminal to 08(SET)/17(SET3) and
switch the input ON.
The Inverter output voltage from the base frequencey to the maximum frequency is the same level as the
voltage selected on the motor voltage selection.

Carrier frequency
The carrier frequency of the PWM wave-form output from the inverter is adjustable
by changing b083.
If the carrier frequency is set higher, the audible noise from motor will be reduced
but the RFI noise and the leakage current may be increased.
This function may help to avoid the resonant frequency of the motor or the mechanical system.

(Note1) The maximum value of the carrier frequency in order to achieve full output current is different
depending on the capacity. When raising the carrier frequency, the rated output current will be reduced.
