C6-03
(0225)
|
Carrier Frequency Upper Limit
|
    
Sets the upper limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User Defined (C6-03 to C6-05)] to set this parameter.

Determined by C6-02
(1.0 - 15.0 kHz)

Setting a Fixed User-Defined Carrier Frequency
When you cannot use C6-02 to set a carrier frequency between set selectable values, you can set the value in C6-03. The carrier frequency will be fixed to the value set to C6-03.
When A1-02 = 0 [Control Method Selection = V/f], set C6-03 = C6-04 [Carrier Frequency Lower Limit] to fix the carrier frequency.
Setting a Variable Carrier Frequency to Agree with the Output Frequency
When A1-02 = 0, set C6-03, C6-04, and C6-05 [Carrier Freq Proportional Gain] as shown in Figure 1 to make the carrier frequency change linearly with the output frequency.
Figure 1. Setting a Variable Carrier Frequency to Agree with the Output Frequency
Note:
-
When C6-05 ≤ 7, the drive disables C6-04. The carrier frequency is fixed to the value set to C6-03.
-
The drive detects oPE11 [Carrier Frequency Setting Error] when these conditions are correct at the same time:
-
When A1-02 = 0, 2, 5, 8 [Control Method Selection = v/f, OLV, OLV/PM, EZOLV], in the area where the output frequency is more than C6-03 and C6-12, the carrier frequency = output frequency × 12, and it will change with the output frequency.
