U7-02, Slave Absolute Frequency, (available as an output to the slave by setting parameter H4-01 to 702), has the same
amplitude of 9 Hz (calculated by P1-02
× Reference Frequency). U7-02 is anti-phase to the master waveform and is
centered around U7-04, the Slave Base Frequency. Since the Slave Base Frequency is 45 Hz, U7-02 varies from
36 to 54 Hz while in Traverse mode. Before entering Traverse mode, the Slave Absolute Frequency will rest at 48 Hz, as
represented by the equation in
Figure 2 .
U7-03, Slave Ripple Frequency, is the same as the U7-02 waveform without the Slave Base Frequency component. Slave
Ripple Frequency U7-03 is a bipolar waveform centered at 0 Hz. The output varies from 21 to 39 Hz during operation.
The Slave Ripple Frequency will rest at 3 Hz before entering Traverse mode as represented by the equation in
Figure 2 .
