C6-09: Carrier Frequency @ RotateTuning

C6-09 Carrier Frequency @
RotateTuning
(022B)
When Auto-Tuning a high frequency motor or low impedance motor and the carrier frequency is set to a low
level, oC [Overcurrent] may occur. To prevent oC from occurring, it may be helpful to set the carrier frequency to
a high value before setting C6-09 = 1.
The procedure to set the carrier frequency varies depending on the setting of A1-02 [Control Method Selection].
• When A1-02 = 2 to 4 [IOLV, CLV, or AOLV], set C6-02 = F [Carrier Frequency Selection = User Defined] and
then increase the value set to C6-03 [Carrier Frequency Upper Limit].
• When A1-02 = 5 to 7 [OLV/PM, AOLV/PM, or CLV/PM], increase the setting value of the carrier frequency
using C6-02.
0 : 5 kHz
Note:
If A1-02 =5, 6, or 7, the carrier frequency is 2 kHz.
1 : use C6-03
Note:
If A1-02 = 5, 6, or 7 , the carrier frequency is the value set to C6-02.
