Setting the V/Hz Curve Jumpers (J9 through J12)
Jumpers J9 through J12 set the frequency break point for the V/Hz Curve . The
breakpoint is the frequency at which the output voltage reaches the maximum voltage.
Below this point the output voltage and frequency increase together. This feature is
required to allow the drive to work with motors rated at various frequencies. Figure 2.2
shows a general V/Hz curve.
