ACH550/ACS320 VFD Diagnostics
The drive detects error situations and reports them using:
•
Green and red LEDs on the body of the drive (located un-
der the keypad)
•
Status LED on the control panel
•
Control panel display
•
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 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 (0305
to 0307)
•
Overriding the control panel display with the display of a
fault code
•
Stopping the motor (if it was on)
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 (0308
or 0309)
•
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 34 for a list of alarm codes.
Correcting Faults
The recommended corrective action for faults is shown in the
Fault Codes Table 33. 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 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.
History
For reference, the last three fault codes are stored into parameters
0401, 0412, 0413. For the most recent fault (identified by parame-
ter 0401), the drive stores additional data (in parameters 0402 -
0411) to aid in troubleshooting a problem. For example, a parame-
ter 0404 stores the motor speed at the time of the fault. To clear the
fault history (all of Group 04, Fault History parameters), follow
these steps:
1.
In the control panel, Parameters mode, select parameter 0401.
2.
Press EDIT.
3.
Press the UP and DOWN buttons simultaneously.
4.
Press SAVE.
