Timing adjustment of the pulse module control signal adjusts with the sustain pulse of eighth pulse (X DRIVE) and 
the ninth pulse (Y DRIVE) from the back of 6SF.

• Perform adjustment of waveform with a black mask screen.
• It is easy to adjust when turned field AB offset to OFF (RS-232C
  command: OCN) in adjustment.

Note:
• Sampling rate of oscilloscope sets it more than 500MS/s in order
  to perform ns order adjustment.
• Collecting calibration of probe before adjustment by all means.

• Connect GND of probe measuring waveform to SUSGND terminal
  by all means.
• Precise waveform is not displayed, and an adjustment gap may
  occur that does not collect GND properly.

When took waveform be each drive Assy unit, measure it at the 
fourth sustain pulse from the back except for a large width sustain 
pulse.
Therefore, when measured both waveform of the X and Y drives 
together, it becomes the sustain pulse of 8 and 9 pulses from the 
back.

When there is a gap with waveform of CH1 / CH2 of the part which 
enclosed in the following circle, adjust required VR to overlap the 
waveform.
