Diagnostic Displays

When a drive detects an error, it provides a diagnostic display. The display appears
using:
• The green and red LED on the body of the drive
• The status LED on the control panel (if a control panel is attached to the drive)
• The control panel display (if a control panel is attached to the drive)
The form of the display depends on the severity of the error.
Red – Faults
The drive signals that it has detected a severe error, or fault, by:
• Enabling the red LED on the drive (LED is either steady on or blinking).
• Overriding the control panel display with the display of a fault code.
• Stopping the motor (if it was on).
The fault code on the control panel display is temporary. Pressing any of the
following buttons removes the fault message: MENU, ENTER, UP button, or DOWN
button. The message reappears after a few seconds if the control panel is not
touched and the fault is still active.

Correcting Faults

The recommended corrective action for faults is:
• Use the "Fault Listing" table below to find and address the root cause of the
problem.
• Reset the drive. See "Fault Resetting" on page 123.
