Drum Maintenance Contact Test
This test exercises the Drum Maintenance Kit. The Drum is driven by a low amplitude vibration
and the Drum Maintenance Kit is advanced through its cycle. The reaction of the Drum servo
error signal indicates when the drum was contacted by the roller and blade.
Motors Menu
This menu contains a test for each of the system motors.
Y-Axis Motor Test
The Y-Axis motor is moved to the Home position, then turned On and run slowly for one revolu-
tion. The slow motion removes the effect of inertia from the test, and the one revolution avoids
a large system status change via any permanently connected loads. With the slow operating
speed used by the test, the motor may stall at a bad commutator segment. Unusual average
values might indicate a weak motor. The motor following error, drive voltage, and power ripple
values indicate how smoothly the motor is able to turn through one revolution. Depending on
the mechanical state of the drive when this test is run, both the ripple and average values may
vary significantly from run to run due to the variation in the external load.
X-Axis Motor Test
The X-Axis motor is turned On and run slowly for one revolution. The slow motion removes the
effect of inertia from the test, and the one revolution avoids a large system status change via
any permanently connected loads. With the slow operating speed used by the test, the motor
may stall at a bad commutator segment. The connected drive cone could modify the drive
power values if the threads were defective, dry, or if the guide notch was disengaged. The A
and B voltage measurements should remain constant if the drive is operating properly.
Process Motor Test
The Process Drive motor is moved to the Home position, then the motor is jogged CW until it
begins to engage the Drum Maintenance Kit. Next, the motor is run slowly CCW for one revolu-
tion. The slow motion removes the effect of inertia from the test, and the one revolution avoids
a large system status change via any permanently connected loads. With the slow operating
speed used by the test, the motor may stall at a bad commutator segment. Unusual average
values might indicate a weak motor. The motor following error, drive voltage, and power ripple
values indicate how smoothly the motor is able to turn through one revolution.
