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
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
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.
