XYZ Machine Tools Ltd
XYZ Bed Mill Safety, Installation, Maintenance, Service & Parts List Manual
Possible Cause
Check This
Wrong voltage
Check the voltage to the machine. Also, check the voltage to the
Spindle Drive (L1, L2, and L3).
Poor wiring connections
Check all the wiring connections to the Spindle Drive and Spindle
Motor. See Electrical Connection
Spindle Drive may be in "Local
Mode"
On the Spindle Drive, check the LED on the LO/RE button it
should be unlit. If lit, press the button once.
Spindle Motor is bad
Check the resistance of the Spindle Motor windings on the Spindle
Motor between L1 & L2, L2 & L3, and L1 & L3, using an
Ohmmeter. The resistance should be 3 Ohms or less and
approximately equal. If the Ohmmeter reads "0 Ohms" or "OL",
then replace Spindle Motor. Next, check the resistance between L1
& Ground, L2 & Ground, and L3 & Ground, using an Ohmmeter.
The resistance should read "OL". If not then replace Spindle Motor.
Spindle Drive incorrectly
configured.
Contact Customer Service for assistance.
Spindle enable signal not
reaching AC Drive
Verify LED on Spindle Control module is on.
Forward/Reverse Switch is bad or
Spindle Control Board
Verify Forward or Reverse LED on Spindle Control module is lit.
3.5.4 Spindle Runs Backwards
The spindle motor runs in the opposite direction. The spindle will run in opposite directions from high to
low gear.
Possible Cause
Check This
3-Phase sequence incorrect.
Swap any two wires leading to the spindle motor (U, V & W).
3.5.5 Head Noise
Head noise pertains to any unusual noises coming from the head under load and no load situations. Most
often head noise will only be noticeable under load situations. It is important to try to distinguish
between problems with components in the head versus problems caused by the setup or tooling being
used on a particular job.Use the table below to try to pinpoint the possible cause. Also try to isolate the
noise by seeing if it exists in high, low or neutral speed range. For example, if the noise is evident in
neutral then this eliminates the spindle bearings.
Possible Cause
Check This
Machine setup or tooling problem
If the noise is most evident under load (cutting situations) then it
is important to look at setup and tooling being used. Ask the
following questions:
Is the cutter dull? Is the tool loose in the holder? Am I taking a
bigger cut than is possible on this machine? Is the part moving in
the vice? Am I using realistic speeds and feeds?
Any one of these can have a significant impact.
Upper spindle bearing is worn.
Remove the upper bearing plate above the spindle. This will
unload the bearing. If the noise goes away then this bearing
should be replaced.
Verify nosepiece is tight on
bottom of spindle.
To check if the nosepiece is bottomed out try to insert a piece of
paper in between the nosepiece and the quill. If a piece of paper
does fit then this may be the problem. Before tightening or
loosening the nosepiece make sure to loosen the setscrew that
holds it in place.
