C6-03, C6-04, C6-05: Carrier Frequency Upper Limit, Lower Limit, Proportional Gain
Note:
C6-04 and C6-05 are available in V/f Control mode only.
These parameters set a user-defined or a variable carrier frequency. Set C6-02 to F to set the upper and lower limits and the
carrier frequency proportional gain.

Setting a Fixed User-Defined Carrier Frequency
A carrier frequency between the fixed selectable values can be entered in parameter C6-03 when C6-02 is set to F.
In V/f Control, adjust parameter C6-04 to the same value as C6-03.
Setting a Variable Carrier Frequency (V/f Control)
In V/f Control, the carrier frequency can be set up to change linearly with the output frequency by setting the upper and lower
limits for the carrier frequency and the carrier frequency proportional gain (C6-03, C6-04, C6-05) as shown in

d1-01 to d1-04, d1-16, and d1-17: Frequency References 1 to 4, 16, and Jog Frequency
Reference
The drive lets the user switch between up to 5 preset frequency references during run (including the Jog reference) through
the digital input terminals. The drive uses the acceleration and deceleration times that have been selected when switching
between each frequency reference.
The Jog frequency overrides all other frequency references and must be selected by a separate digital input.
The multi-speed references 1 and 2 can be provided by analog inputs.
