Carrier fre-

upper limit
Sets the carrier frequency upper limit
and lower limit in kHz units.
The carrier frequency gain is set as
follows:
In the Open Loop and Closed Loop
Vector control, the upper limit of the
carrier frequency is fixed with C6-
03.
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
