Troubleshooting Suggestions
Important Considerations
• Drive cooling is extremely important to the
overall service life of the product. Extreme care
should be used to keep cooling air paths clean.
Drive cabinet enclosures have been designed to
optimize cooling. Keep cabinet doors closed and
panels installed to maintain proper operation.
• Resetting a fault will not correct the cause of the
fault condition. Corrective action must be taken
prior to resetting a fault. Many drive error codes
are reset by cycling power to the drive. The fault
may not reappear until drive operation is
initiated.
• Drive to motor wiring is critical to proper drive
operation. Loose or bad connections can generate
heat and increase current output from drive.
These problems can manifest themselves in
operation by many fault codes indicating
overcurrent condition and maximum retries fault.
Problem/Corrective Action
Problem:
Wash basket does not rotate.
Corrective Action
1. Ensure computer control display on washer is
showing proper operation.
2. Check power circuit, supply voltage, fuses and
disconnects.
3. Verify drive to motor wires are damage free,
properly connected and torqued to specifications.
4. Check belt tension and condition.
5. Verify no mechanical problems exist (i.e.,
binding, motion restriction).
6. Check control input signals. Refer to applicable
table of inputs.
Problem:
Drive started but wash basket is not rotating.
Corrective Action
1. Verify drive to motor wires are damage-free,
properly connected and torqued to specifications.
2. Verify no mechanical problems exist (i.e.,
binding, motion restriction).
3. Check control input signals. Refer to applicable
table of inputs.
Problem:
Wash basket not accelerating properly.
Corrective Action
1. Verify drive to motor wires are damage-free,
properly connected and torqued to specifications.
2. Verify speed selection control wire connections.
Refer to applicable table.
Problem:
Drive gives Serial Fault (F10) when HIM is removed
from the drive.
Corrective Action
1. Cycle power to drive to clear the fault.
When a HIM is disconnected with the drive powered,
communication is lost and a fault results. Always
remove power from the drive prior to HIM or PKM
removal or installation.
Problem:
HIM displays “Pin ID Error” or “Network Error.”
Corrective Action
1. Place the HIM directly on the drive.
This communication error with the drive may be the
result of a bad cable or connector that establishes
communication with the HIM.
Problem:
HIM displays “Not Enabled.”
Corrective Action
1. Verify the jumper connecting the control terminal
“Enable” to “Common” is present and is not
loose.
This connection must be present to enable the drive.
