Master Parameter Changes
• H2-01 = 41h: Provide during disturb status output to slave.
• H4-01 = 703: Provide disturbed frequency ripple to slave.
• H4-07 = 1: Provide a bipolar analog output signal.
• P1-01 = 1: Enable Traverse functionality.
• P1-02 ~ P1-05 = application requirements: Define the characteristics of the disturbed frequency.
• P1-06 = application requirement: Define scan offset to account for system delays.
Slave Parameter Changes
• C1-03 = 0.0 sec: Set acceleration time 2 to 0.0 seconds.
• C1-04 = 0.0 sec: Set deceleration time 2 to 0.0 seconds.
• H1-08 = 7: Switch between accel/decel time 1/2 based on During Disturb output.
• P1-01 = 1: Enable Traverse functionality.
• DIP Switch S1 = V: Enable voltage input to A2.
• H3-09 = 1: Set A2 to a -10V to +10V bipolar input.
„ Implementation
Situation 1: Standard Operation
When programmed with the settings as shown in Table 10 , the Traverse software produces output waveforms similar to
the ones in Figure 2 . Using these settings and a reference frequency of 45 Hz, the master drive operates based on the
triangle waveform with 9 Hz (peak-peak) amplitude. Because the waveform is centered on the 45 Hz reference frequency,
the master waveform oscillates between 36 and 54 Hz while in Traverse mode.
