Function of Each Parameter
18
Carrier Frequency Selection (n46)
Set the carrier frequency.
Value Description
1 2.5 kHz
2 5.0 kHz
3 7.5 kHz
4 10.0 kHz
7 2.5 kHz (12×): 12 times as high as output frequency (between 1.0
and 2.5 kHz)
8 2.5 kHz (24×): 24 times as high as output frequency (between 1.0
and 2.5 kHz)
9 2.5 kHz (36×): 36 times as high as output frequency (between 1.0
and 2.5 kHz)
Note: Normally, the factory setting need not be changed.
Momentary Power Interruption Compensation
(n47)
The parameter specifies the processing that will be performed
when a momentary power interruption occurs.
Value Description
0 Disabled.
1 The Inverter will continue operating if power is restored within 0.5
s.
2 The Inverter will restart when power is restored.
Fault Retry (n48)
Set the number of times the Inverter is to be automatically reset
and restarted when the Inverter has an overvoltage fault, over-
current fault, or ground fault.

Note: 1. Values will be set in 0.1-Hz increments if the frequency is less
than 100 Hz and 1 Hz-increments if the frequency is 100 Hz
or greater.

Stall Prevention during Deceleration (n55)
Select a function to change the deceleration time of the motor
automatically so that there will be no overvoltage imposed on the
motor during deceleration.
Value Description
0 Stall prevention during deceleration
1 No stall prevention during deceleration
