Descriptions
Self-diagnostic
malfunction
Displayed when IGBT damage, output phase short, output phase
ground fault or output phase open occurs.
Parameter save
error
Displayed when user-setting parameters fails to be entered into
memory.
Inverter
hardware fault
Displayed when an error occurs in the control circuit of the
inverter.
Communication
Error
Displayed when the inverter cannot communicate with the
keypad.
Remote keypad
communication
error
Displayed when inverter and remote keypad does not
communicate each other. It does not stop Inverter operation.
Keypad error
Displayed after Inverter resets keypad when keypad error occurs
and this status is maintained for a certain time.

turns off the output when the EST terminal is turned on.
Caution:
The inverter starts to regular operation when turning off the EST
terminal while FX or RX terminal is ON.
External fault A
contact input
When multi-function input terminal (I17-I24) is set to 18 {External
fault signal input: A (Normal Open Contact)}, the inverter turns off
the output.
External fault B
contact input
When multi-function input terminal (I17-I24) is set to 19 {External
fault signal input: B (Normal Close Contact)}, the inverter turns off
the output.
Operating
method when the
frequency
command is lost
When inverter operation is set via Analog input (0-10V or 0-20mA
input) or (RS485) and no signal is applied, operation is done
according to the method set in I62 (Operating method when the
frequency reference is lost).
NTC open When NTC is not connected, outputs are cut off.
Brake control
error
When the External Brake control function is activated, if the rating
current flows below the set value during over 10 sec, the output is
cut off without opening the brake.
