13.5.2 Problems with inverter settings
[ 1 ] Nothing appears on the monitors.
Possible Causes What to Check and Suggested Measures
(1) No power (neither main
power nor auxiliary control
power) supplied to the
inverter.
Check the input voltage and interphase voltage unbalance.
Î Turn ON a molded case circuit breaker (MCCB), a residual-current-
operated protective device (RCD)/earth leakage circuit breaker (ELCB)
(with overcurrent protection) or a magnetic contactor (MC).
Î Check for voltage drop, phase loss, poor connections, or poor contacts
and fix them if necessary.
(2) The power for the control
PCB did not reach a
sufficiently high level.
Check if the jumper bar has been removed from terminals P1 and P(+) or if
there is a poor contact between the jumper bar and those terminals.
Î Mount a jumper bar or a DC reactor between terminals P1 and
P(+). For poor contact, tighten up the screws.
Check whether the keypad is properly connected to the inverter.
Î Remove the keypad, put it back, and see whether the problem recurs.
Î Replace the keypad with another one and check whether the problem
recurs.
(3) The keypad was not
properly connected to the
inverter.
When running the inverter remotely, ensure that the extension cable is
securely connected both to the keypad and to the inverter.
Î Disconnect the cable, reconnect it, and see whether the problem recurs.
Î Replace the keypad with another one and check whether the problem
per recurs.
[ 2 ] The desired function code does not appear.
Possible Causes Check and Measures
(1) The function code is not
located in the current
directory.
Check whether the function code is located in a different directory.
Î Display the function codes in the directory, referring to Chapter 3,
Section 3.4.4 "Programming Mode."
If o codes do not appear, check whether an option board is mounted.
Î Display the function codes in the directory, referring to Chapter 3,
Section 3.4.4 "Programming Mode."
Note: No o codes appear unless an option board is mounted.
