7-1 If You Think Defective
· After the inverter protective function was activated and you removed the cause, if you reset the alarm
while the operation command has been set to ON, the inverter restarts. Reset the alarm after you confirm
the operation command has been set to OFF.
You may be injured.
7-1-1 If You Think Defective
An inverter may not operate as instructed while you think you specified the operation command and the
speed reference properly or you may not reset the alarm to restart operation. Also an alarm may occur
frequently to obstruct the operation of a facility.
If this is the case, use the KEYPAD panel to identify the cause of the malfunction or the alarm. If you still
cannot identify the cause or you suspect an inverter fault or damaged parts, contact the shop you
purchased the inverter or the FUJI's sales representative.
7-1-2 What You Should Check First
This section describes how to use the KEYPAD panel to investigate causes though the protective function is
not activated, but an inverter does not operate as instructed. Then the flowcharts illustrate the procedures.
(1) Is the inverter ready for operation?
It takes about one minute before an inverter becomes ready for operation after you
turn on the main circuit. You can view the "CHARGE" lamp on the front of an
inverter with 18.5kW or more capacity to confirm this state. Also you should use
the "I/O check" screen of the KEYPAD panel to check if "
n
NUV" is displayed as
shown in the right figure. This status indicates that the inverter is ready for
operation.
If "
o
NUV" is displayed, the power may not be supplied to the inverter. Check the
input power line to the main circuit.
When you do not use a DCR, you should connect a jumper wire between P1 and
P(
+
) terminals. Check if the jumper wire is not disconnected.
(2) Have you instructed an operation command?
Following the procedure described above to confirm that the inverter is ready.
When you direct the operation command (FWD), "RUN" must be displayed as in the
right figure.
If the display remains "STOP", the inverter has not received your operation
command.
When you enter the operation command from the KEYPAD panel, a green
indicator RUN LED turns on.
You can see the indicator on the LCD monitor to check the available source of the operation command
(LOC: KEYPAD panel, REM: External signal, and COMM: link).
You should change the function code F02 "Operation method" and H30 "Serial link"
to change the source of the operation command.
If you have installed an option, you cannot use RS485 to enter the operation
command (the option has higher priority). When you have several options, the
priority may be fixed. See the description of applicable options.
When you use the UPAC, you should enter the operation command as well. See
the description of the UPAC for more details.
