ACH580 VFD Diagnostics
The drive detects error situations and reports them using:
• Status LED on the control panel
• Control panel display
• The Fault Word and Alarm Word parameter bits
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 re-
port the situation as a fault.
FAULTS (RED LED LIT)
The VFD signals that it has detected a severe error, or fault, by:
• Enabling the red LED on the drive (LED is either steady or
flashing)
• Setting an appropriate bit in a Fault Word parameter
• 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
the MENU, (Press ). 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. See Table 35 for a list of fault
codes.
ALARMS (GREEN LED FLASHING)
For less severe errors, called alarms, the diagnostic display is advi-
sory. For these situations, the drive is simply reporting that it had
detected something unusual. In these situations, the drive:
• Flashes the green LED on the drive (does not apply to
alarms that arise from control panel operation errors)
• Sets an appropriate bit in an Alarm Word parameter
• Overrides 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. See Table 35 for a list of alarm codes.
CORRECTING FAULTS
The recommended corrective action for faults is shown in
Table 35. 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 flash-
ing), press RESET from the control panel or turn off the power for
5 minutes. Depending on the value of parameter, digital input or
serial communication could also be used to reset the drive. When
the fault has been corrected, the motor can be started.
CORRECTING ALARMS
To correct alarms, first determine if the alarm requires any correc-
tive action (action is not always required). Use Table 35 to find
and address the root cause of the problem.
If diagnostics troubleshooting has determined that the drive is de-
fective during the warranty period, contact Carrier.
