Displayed when the I/O board or external
communication card is not connected to the inverter or
there is a bad connection.
Displayed when the error code continues for
more than 5 sec.
(‘Errc’ -> ’-rrc’ -> E-rc’ -> ’Er-c’ -> ‘Err-‘ -> ’- -rc’ -> ‘Er- -‘ -
> ’- - - -‘
-> ’Errc’ -> …)
Displayed when communication fails during parameter
writing. Occurs when using an LCD keypad due to a
control cable fault or a bad connection.
Displayed when a communication error is detected
between the inverter and the communication board.
Occurs when the communication option card is installed.
Warning Messages
Displayed when the motor is overloaded. Operates when Pr.17 is
set to 1. To operate, select 5. Set the digital output terminal or relay
(OU.31 or OU.33) to 5 (Over Load) to receive overload warning
output signals.
Displayed when the motor is underloaded. Operates when Pr.25 is
set to 1. Set the digital output terminal or relay (OU.31 or OU.33) to
7 (Under Load) to receive underload warning output signals.
Displayed when the overload time equivalent to 60% of the inverter
overheat protection (inverter IOLT) level, is accumulated. Set the
digital output terminal or relay (OU.31 or OU.33) to 6 (IOL) to
receive inverter overload warning output signals.
Lost command warning alarm occurs even with Pr.12 set to 0. The
warning alarm occurs based on the condition set at Pr.13- 15. Set
the digital output terminal or relay (OU.31 or OU.33) to 13 (Lost
Command) to receive lost command warning output signals. If the
communication settings and status are not suitable for P2P, a Lost
Command alarm occurs.
Displayed when an error is detected from the cooling fan while
Pr.79 is set to 1. Set the digital output terminal or relay (OU.31 or
OU.33) to 8 (Fan Warning) to receive fan warning output signals
