Application and Overload Selections

Select the Overload to Suit the Application

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.

* 1. Only 1(VT) can be set for 200 V Class 110 kW as well as 400 V Class 220 kW and 300 kW Inverters.
* 2. The factory settings depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.
* 3. The setting ranges depend on the capacity of the Inverter. The values for a 200 V Class Inverter of 0.4 kW are given.
* 4. This constant can be monitored or set only when F is set for C6-02.

Name Description
0: CT (low carrier, constant torque,
150% per minute)
1: VT (high carrier, variable torque,
120% per minute)
Select carrier wave fixed pattern.
0: Low-noise PWM
1: 2.0 kHz
2: 5.0 kHz
3: 8.0 kHz
4: 10.0 kHz
5: 12.5 kHz
6: 15.0 kHz
F: Enables detailed settings using
constants C6-03 to C6-05
Set the carrier frequency upper limit and
lower limit in kHz units.
The carrier frequency gain is set as fol-
lows:
With the vector control method, the
upper limit of the carrier frequency is
fixed in C6-03.
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
