Maintenance and diagnostics
4-20 MicroEDGE Pro Instruction Manual 807290
Symptoms / Indications Corrective Action
Motion issues, continued
for a 2 axis Picopath interface without the test kit:
1. To prevent damage to the table and components, remove all motors from the rack or
couplers.
2. Go to Setups > Diagnostics > Drives and Motors > Enter Machine password.
3. Enter:
• A Pulse Type of “Single”
• A Pulse Direction “Alternating”
• A Pulse Magnitude of 1 V
• A Pulse Duration of 0.5 seconds
Choose the Test Transverse and Test Rail buttons, one at a time and verify that
motors move in both directions for each test. If there is no movement in any of the
axes, in any direction, check the table setup. If motion is observed properly in all
directions, proceed to step 4.
4. If there is no movement in one of the directions, take note of which motor it is.
Switch the two motors physically and re-run the test in step 2. If the problem stays
with the motor, replace the affected motor and/or drive amplifier. If the problem
changes motors, replace the following components, one at a time and re-run the
tests in steps 2 and 3 after each replacement:
• Servo board
• MCC
• Ribbon cable (223231)
5. Re-run step 3, taking care to observe the transverse and rail position indicators. If
these indicators are moving in a repeatable manner, all components are working
as expected and the table should be tuned. If one or more of the indicators are not
responding when the table is moving, take note of which indicator is not responding
properly and proceed to step 4.
