YASKAWA Varispeed G7 Series User Manual

User Constant Tables
5- 27
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 and the control method. 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 6-44).
* 6. This setting is for software versions PRG 1040 and later. The factory setting with software versions PRG 1039 and earlier depends on the Inverter
capacity.

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
