Possible Causes What to Check and Suggested Measures
(3) The WE-KP command
("Enable editing of
function codes data from
keypad") is not input
though it has been
assigned to a digital input
terminal.
Check the data of function codes E01, E02, E03, E98 and E99
and the input signals with Menu #4 "I/O checking" using the
keypad.
Î Cancel data protection of the function codes or turn on the
"Enable editing of function codes data from keypad"
command.
(4) DC link circuit voltage was
below the undervoltage
detection level.
Check the DC link circuit voltage with Menu #5 "Maintenance
information" and measure the input voltage using the keypad.
Î Supply power to match the inverter’s input rating and
change the data of the function codes.
[ 2 ] The desired menu is not displayed.
Causes Check and Measures
(1) The limiting menus
function was not selected
appropriately.
Check the data of function code E52.
Î
Change the data of function code E52 to display the desired
menu.
[ 3 ] Nothing appears on the LED monitor.
Possible Causes What to Check and Suggested Measures
(1) No power supplied to the
inverter.
Check the input voltage, output voltage and interphase voltage
unbalance.
Î Connect a molded case circuit breaker, an earth leakage
circuit breaker (with the exception of those exclusivel
y
designed for protection from ground faults) or a magneti
c
contactor.
Î Check for voltage drop, phase loss, poor connections, o
r
poor contacts, and fix them if necessary.
(2) The power for the control
circuit did not reach a high
enough level.
Check if the jumper bar has been removed between terminals
P1 and P (+) or if there is poor contact between the jumper ba
r
and the terminals.
Î Connect the jumper bar to terminals P1 and P (+) or tighten
the screws. Or connect a DC reactor.
Î Replace the inverter if it is malfunctioning.
