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 rests at 48 Hz as represented by the equation in Figure 2 .
U7-03, Slave Ripple Frequency, is similar to U7-02, except that this anti-phase dither is
centered around 50% of the drive Maximum Output Frequency. With E1-04 set to 60.0 Hz,
U7-03 is centered around 30 Hz, and varies from 21 to 39 Hz during operation. Before
entering Traverse mode, the Slave Ripple Frequency rests at 33 Hz, as represented by the
equation in Figure 2 .
Situation 2: Traverse Operation Exceeds Maximum Output Frequency
Using the settings in Table 10 and a reference frequency of 52 Hz, the Traverse software
produces output waveforms similar to those in Figure 3 . With an amplitude of 10.4 Hz, the
traverse software produces a triangle output that varies from 41.6 to 62.4 Hz. Setting drive
parameter E1-04 to 60.0 Hz, caps the triangle waveform when the traverse frequency
exceeds the Maximum Output Frequency of 60 Hz.
