Servo Motor Errors (Move Time Out, Tracking, and Over Current Errors)
This error occurs when the machine takes too long to nd the home or index position when the software
is prompted to move. Typically, this is a break in continuity of home sensor circuit.
Troubleshoot motor timeout errors using the following procedures for the affected motor:
Step Action Result Next Step/Solution
1 Look for an obstruction to the
respective axis served by the
motor. Obstructions can in-
clude, but are not limited too:
fabric stuck in the machine,
corrosion to the shafts, lack of
lubrication, damaged bearings.
You might have to replace
both the shafts and bearings if
lack of lubrication is the cause.
Dry shafts or rails but no
corrosion
Lubricate the shafts
Dry shafts or rails, corrosion
present
Replace the shafts
Damaged Bearing Replace the bearing
Obstruction found Remove obstruction
No damage or corrosion Go to Step 2
2 Check the belt tensions and
condition of the belts for the
respective motor servicing the
axis.
Tensions loose or tight Retension belt
For x-axis errors, also check
the adjustment on the carriage
bearings.
Tensions in specication Go to Step 3
3 Inspect the main PCB for obvi-
ous damage around the area
where the motor harness con-
nects to, especially the frets.
Look for burned items.
Visible electrical burn or other
obvious PCB damage
Replace the main PCB
No obvious damage Go to Step 4
4 Look for loose optical sensors,
harness connections, or obvi-
ous damage to the harnesses
Damaged Replace it
Loose Tighten screw or connector
No loose connection or
damage
Go to Step 5
5 Conduct an optical sensor
test to verify that the optical
sensors servicing the affected
circuit are working
Sensors defective Replace the sensors
Sensors good Go to Step 6
6 Reboot the software and turn
the machine off and then back
on.
Problem does not recur Probably data corruption in the
rmware or software
Problem recurs Go to Step 7
