Maintenance and diagnostics
4-18 MicroEDGE Pro Instruction Manual 807290
Symptoms / Indications Corrective Action
Motion issues
• Erratic motion
• An axis “runs away”
• No motion is observed
• There is a high number of posi-
tion errors
• Parts may not be to tolerance
for HyPath interfaces with the test kit (228832):
See the Diagnostics tests section, earlier in this manual.
for HyPath interfaces 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.
In the back of the CNC, switch the Axis 1–2 and Axis 3–4 cables, and re-run
the test in step 2 (for 2 axis systems, you must switch the motors physically).
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.
