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.

Related 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.
