7.6 ADJUSTMENTS WHEN THE DRIVE ASSYS ARE REPLACED
TIME LAG ADJUSTMENT OF THE CONTROL SIGNAL (SUS-B)
1 Measure the time lag for the SUS-U signal to the SUS-B signal.
2 Check the time lag for the SUS-B GATE signal to the SUS-U GATE siganl.
Adjust the variable control so that the time lag of GATE becomes " time lag of input signal + α ± 5 nsec."
Note: For details on measuring points of waveform, see the figure below.

time lag of SUS-U gate and SUS-B gate : ∆ Tsus-gub
Adjust so that "∆ Tsus-gub = ∆ Tsus-iub + α ± 5 nsec," using the variable
controls shown in the table below:
SUS-U signal (input to the DRIVE Assy)
SUS-B signal (input to the DRIVE Assy)
SUS-U signal (input to the DK module)
SUS-B GATE signal
