C6-09

(022B)

Carrier Freq at Rotational Tune

Sets the Auto-Tuning carrier frequency. Usually it is not necessary to change this setting.

0

(0, 1)

If you set C6-09 = 0 for a high-frequency or low-impedance motor, it can cause oC [Overcurrent]. To prevent oC, set the carrier frequency to a high value and set C6-09 = 1 before you do Auto-Tuning.

 

The procedure to set the carrier frequency when the A1-02 [Control Method Selection] setting changes.

  • When A1-02 = 2, 3 [OLV, CLV], set C6-02 = F [Carrier Frequency Selection = User Defined (C6-03 to C6-05)] and then increase the value set to C6-03 [Carrier Frequency Upper Limit].

  • When A1-02 = 4 to 7 [AOLV, OLV/PM, AOLV/PM, or CLV/PM], use C6-02 to increase the carrier frequency.

0
5kHz
Note:

When A1-02 = 5, 6, 7 [Control Method Selection = OLV/PM, AOLV/PM, CLV/PM], the carrier frequency is 2 kHz.

1
use C6-03
Note:

When A1-02 = 5, 6, 7 [Control Method Selection = OLV/PM, AOLV/PM, CLV/PM], the carrier frequency is as specified in C6-02.
