VFD Diagnostics
The drive detects error situations and reports them using:
1. the green and red LEDs on the body of the drive (located
under the keypad)
2. the status LED on the control panel
3. the control panel display
4. the Fault Word and Alarm Word parameter bits (parame-
ters 0305 to 0309)
The form of the display depends on the severity of the error.
The user can specify the severity for many errors by directing
the drive to ignore the error situation, report the situation as an
alarm, or report the situation as a fault.
FAULTS (RED LED LIT)
The VFD signals that it has detected a severe error, or fault, by:
1. enabling the red LED on the drive (LED is either steady or
flashing)
2. setting an appropriate bit in a Fault Word parameter (0305
to 0307)
3. overriding the control panel display with the display of a
fault code
4. stopping the motor (if it was on)
The fault code on the control panel display is temporary. Press-
ing the MENU, ENTER, UP button or DOWN buttons re-
moves the fault message. The message reappears after a few
seconds if the control panel is not touched and the fault is still
active.
