These parameters cannot be changed during operation.
Note The setting range and the factory default setting vary according to the Inverter capacity. The table
shows a value of 200-V class, 0.4 kW.
In the vector control modes, the carrier frequency is determined by the carrier frequency upper limit
(parameter C6-01).
In the V/f control modes (both with and without PG), the carrier frequency can be changed in response to
the output frequency by setting the carrier frequency lower limit (parameter C6-02) and the carrier fre-
quency proportional gain (parameter C6-03).
The coefficient “K” varies depending on the carrier
frequency upper limit, as described below:
Carrier frequency
Output frequency
x (C6-03) x K
Output frequency
(Maximum output frequency)
E1-04
C6-01
C6-02
To make the carrier frequency constant, either set the same value for parameters C6-01 and C6-02 or
set the carrier frequency proportional gain (parameter C6-03) to “0” (i.e., fix at upper limit value).
The following settings will generate a parameter setting fault (OPE11):
Carrier frequency upper limit (C6-01) > 5.0 kHz and carrier frequency lower limit (c6-02)
x
5.0 kHz
Carrier frequency proportional gain (C6-03) > 6 and (C6-01) < C6-02)
If the lower limit is set higher than the upper limit, the lower limit will be ignored and carrier frequency will
be fixed at the upper limit.
Note For a 400-V Inverter, if the carrier frequency is set to a value higher than the default setting, the
Inverter’s rated output current will decrease. If the Inverter’s overload is detected earlier than the
motor overload fault (OL2), set the carrier frequency to a lower value.
