Inverter

hardware fault

This fault message is displayed when an error occurs in the control circuitry of the

inverter.

Communication

Error

This fault message is displayed when the inverter cannot communicate with the keypad.

Cooling fan

fault

This fault message is displayed when a fault condition occurs in the inverter cooling fan.

Used for the emergency stop of the inverter. The inverter instantly turns off the output

when the EST terminal is turned on.

Instant cut off

☞

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 (I20-I24) is set to 19 {External fault signal input : A

(Normal Open Contact)}, the inverter turns off the output.

External fault B

contact input

When multi-function input terminal (I20-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 option

(RS485) and no signal is applied, operation is done according to the method set in I62

(Operating method when the frequency reference is lost).
