General Troubleshooting
Reports the static difference
between the average ya_fe
before and after the blade
disengages from the drum,
indicating the strength of the
blade/drum interaction while
pulling off the drum. (See R0).
Reports the time between the
disengagement of the stripper
sol and the point when the blade
begins to withdraw from the
drum (see R2).
Reports the time between the
disengagement of the stripper
sol and the point when the
reaction of the drum to the
withdrawal of the blade fades
back into the ripple (see R2).
Reports the magnitude of the
reaction of the drum to the blade
withdrawal (see R3).
Results Interpretation/Actions
Reports the distance the pm
motor was moved (raising the
dm unit), before a Y-axis
reaction was detected. Shows
that the dm is raising, provides
blade/drum gap information.
