YASKAWA varispeed G7 CIMR-G7B series - User Constants for Carrier Frequency: C6

5-26
Carrier Frequency: C6
User constants for the carrier frequency are shown in the following table.
* 1. The factory settings depend on the capacity of the Inverter. The values for a 200 V Class Inverter for 0.4 kW are given.
* 2. The setting ranges depend on the capacity of the Inverter. The values for a 200 V Class Inverter for 0.4 kW are given.
* 3. This constant can be monitored or set only when F is set for C6-02.
* 4. Displayed in Quick Programming Mode when motor 2 is set for a multi-function input.
* 5. The maximum output frequency depends on the setting for the carrier frequency (refer to page 6-43).
* 6. The factory setting for 400V 132kW and 220kW flax vector control (A1-02 = 3) is 1.5 kHz, for software version VSG123032 or later.

Carrier
frequency
upper limit
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.
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
