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 1.27
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:
C6-03 > 10.0 kHz
10.0 kHz > C6-03 > 5.0 kHz
C6-03 < 5.0 kHz
Important: If C6-05 > 6 and C6-04 > C6-03 the iQpump drive will fault and display and OPE11 error.
