DELAY ADJUSTMENT OF THE CONTROL SIGNAL (SUS-B)
A

1 Measure the delay time for the SUS-U signal. 2 Check the delay time for the SUS-B signal. Adjust the variable control so that the SUS-B delay time becomes "SUS-U delay time + α ± 5 nsec." Note: For details on measuring points of waveform, see the figure below.
1.5 V SUS-U signal (input to the DRIVE Assy) 5V SUS-U signal (input to the DK module)

B

SUS-U delay time � Tsus-u 1.5 V SUS-B signal (input to the DRIVE Assy) 5V SUS-B signal (input to the MSK module) SUS-B delay time � Tsus-b
C

Value of α

SUS-B delay time: � Tsus-b Adjust so that "� Tsus-b = � Tsus-u + α ± 5 nsec," using the variable controls shown in the table below:

DELAY ADJUSTMENT OF THE CONTROL SIGNAL (SUS-G)
1 Measure the delay time for the SUS-D signal. 2 Check the delay time for the SUS-G signal. Adjust the variable control so that the SUS-G delay time becomes "SUS-D delay time + β ± 5 nsec." Note: For details on measuring points of waveform, see the figure below.
