12.3 C: TUNING
SIEPCYEUOQ2V01A Q2V Technical Manual 507
Set C6-03 [Carrier Upper Frequency Limit], C6-04 [Carrier Lower Frequency Limit], and C6-05 to make the
carrier frequency change linearly with the output frequency.
■ C6-09: Carrier@Autotune Rotational
No.

C6-09
(022B)
Carrier@Autotune
Rotational
Sets the Auto-Tuning carrier frequency. Usually it is not necessary to change this setting.
0
(0, 1)
If C6-09 = 0 and you do Auto-Tuning on a high frequency motor or low impedance motor, it can cause oC
[Overcurrent]. To prevent oC, increase the carrier frequency value, set C6-09 = 1, then do Auto-Tuning.
The procedure to set the carrier frequency when the A1-02 [Control Method] setting changes.
• When A1-02 = 2 [OLVector], set C6-02 = F [Carrier Frequency Selection = User (C6-03 to C6-05)] and then
increase the value set to C6-03 [Carrier Upper Frequency Limit].
• When A1-02 = 5 or 6 [PM OLVector or PM AOLVector], use C6-02 to increase the carrier frequency.
0 : 5 kHz
Note:
When A1-02 = 5 or 6, the carrier frequency is 2 kHz.
1 : use C6-03
Note:
When A1-02 = 5 or 6, the carrier frequency is the value set to C6-02.
