* 1. The factory setting depends on the capacity of the Inverter.
* 2. The setting range depends on the capacity of the Inverter.
* 3. This constant can be monitored or set only when C6-02 is set to F.

Name Description
Selects the carrier frequency.
Select F to enable detailed settings
using constants C6-03 to C6-05.
Sets the carrier frequency upper limit
and lower limit in kHz units.
The carrier frequency gain is set as fol-
lows:
Carrier frequency
Output frequency x (C6-05) x K
(Max. output frequency)
K is a coefficient that depends on the setting
of C6-03.
C6-03 ≥ 10.0 kHz: K = 3
10.0 kHz > C6-03 ≥ 5.0 kHz: K = 2
5.0 kHz > C6-03: K = 1
