About VFD Troubleshooting

This section describes some troubleshooting tools for the VFDs.

Error Checking on the Variable Frequency Drives

VFDs (Variable Frequency Drives) interact with hinge and faceplate routers, width
adjust motors, and feed motors. If issues occur, error codes are displayed on the VFDs.
To help troubleshoot, refer to the VFD manuals located in the High Frequency Panel
for lists of the error codes.

Using the Reset Buttons

In some rare occasions an electrical spike may cause a VFD to shut down. The reset
buttons are located on the door of the VFD panels. The button contains the VFD func-
tion printed on the button. If a VFD is tripped to “OFF” the button will be lit. To reset
a VFD:

1.

Push lighted button to reset the indicated motor

b.If the button light turns off, continue with production.
c.If the button stays lit:

• identify the motor by way of the label on the button.
• turn off that function at the switch panel. Check the corresponding output

on the PLC output. If the output is on it will not let the motor reset. Dis-
connect the output wire and verify that the motor circuit is not causing
the issue.

d.If issue continues, read error code on the VFD

*

display and look up the error

code in the VFD manual. Follow the instructions in the VFD manual. If issues
continue, contact our Service Center.

FIGURE 4- 29.

VFD Reset Buttons

Note:

The number of reset buttons depends on the machine type and option. The fig-

ure above shows a machine with 11 VFDs

*

The VFD manuals are located in the Electrical Panels. On some machines, documentation can be found in the operation station in the documen-

tation folder.
