It is possible to configure the iQpump drive such that the carrier frequency will automatically increase as the output frequency is raised
(synchronous carrier). A synchronous carrier can be used by setting parameter C6-02=F: Program. The profile of the carrier frequency is
show below and can be configured to the users specification by setting the carrier frequency upper and lower limits (C6-03 and C6-04
respectively) and a carrier frequency proportional gain (C6-05).

Figure 27 Synchronous Carrier Frequency Characteristics
The frequencies that correspond to the breakpoints a and b will be determined by the value of K given in the table below and the
following formulas:
Important: If C6-05 > 6 and C6-04 > C6-03 the iQpump drive will fault and display and OPE11 error.
