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