User Parameter Tables
5-27
!Carrier Frequency: C6
User parameters for the carrier frequency are shown in the following table.
* 1. The setting range depends on the control method of the Drive.
* 2. Initial values vary depending on drive capacity.
* 3. Setting range varies based on drive capacity.
* 4. This parameter can be monitored or set only when 1 is set for C6-01 and F is set for C6-02.
* 5. Quick Settings are used if Multi-Function Input is set for two motors.

Selection
Selects the number of pulses per second
of the output voltage waveform. Setting
range determined by C6-01 setting.
0: Low noise
1: Fc = 2.0 kHz
2: Fc = 5.0 kHz
3: Fc = 8.0 kHz
4: Fc = 10.0 kHz
5: Fc = 12.5 kHz
6: Fc = 15.0 kHz

Upper
Limit
Sets the relationship of output frequency
to carrier frequency when C6-02 = OF.
Note: Carrier frequency is set to C6-03
(upper limit) when operating in Vector
Control Mode.
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
