VFD Diagnostics

The drive detects error situations and reports them using:

SGreen and red LEDs on the body of the drive (located under the

keypad)

SStatus LED on the control panel S Control panel display

S The Fault Word and Alarm Word parameter bits (parameters 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:

SEnabling the red LED on the drive (LED is either steady or flashing)

SSetting an appropriate bit in a Fault Word parameter (0305 to 0307)

SOverriding the control panel display with the display of a fault

code

SStopping the motor (if it was on)

SSets an appropriate bit in Fault Word parameter 0305- 0307.

The fault code on the control panel display is temporary. Pressing the MENU, ENTER, UP button or DOWN buttons removes the fault message. The message reappears after a few seconds if the control panel is not touched and the fault is still active.

Alarms (Green LED Flashing)

For less severe errors, called alarms, the diagnostic display is advisory. For these situations, the drive is simply reporting that it had detected something unusual. In these situations, the drive:

SFlashes the green LED on the drive (does not apply to alarms that arise from control panel operation errors)

SSets an appropriate bit in an Alarm Word parameter (0308 or 0309)

SOverrides the control panel display with the display of an alarm code and/or name

Alarm messages disappear from the control panel display after a few seconds. The message returns periodically as long as the alarm condition exists.

Correcting Faults

The recommended corrective action for faults is shown in the Fault Listing Table 41. The VFD can also be reset to remove the fault. If an external source for a start command is selected and is active, the VFD may start immediately after fault reset.

To reset a fault indicated by a flashing red LED, turn off the power for 5 minutes. To reset a fault indicated by a red LED (not flashing), press RESET from the control panel or turn off the power for 5 minutes. Depending on the value of parameter 1604 (FAULT RESET SELECT), digital input or serial communication could also be used to reset the drive. When the fault has been corrected, the motor can be started.
