Set C6-01 (CT: Low carrier constant torque, VT: High carrier variable torque) depending on the application
for which the Inverter is used. The setting ranges for the Inverter carrier frequency, overload tolerance, and
maximum output frequency depend on the setting in C6-01. If using the Inverter with C6-01 set to the factory
setting (1: VT), use a load application in which load torque reduces with the speed, e.g., fans and pumps.
nRelated Parameters
*1.The factory settings depend on the Inverter capacity.
*2.The setting ranges depend on the Inverter capacity.
*3.Can be set and referenced only when C6-01 is set to 1, and C6-02 is set to F.

Set the carrier wave gain as shown below.
In vector control method, the carrier frequency is
fixed according to C6-03 (Carrier Frequency
Upper Limit).
K is the coefficient determined by the set value in
C6-03.
C6-03 ≥ 10.0 kHz: K = 3
