CHAPTER 7   COUNTERMEASURE FOR ABNORMALITY

21

7.1 Trip display

When the inverter is in a tripped state, the inverter displays an error code (See table below). The trip history

monitor (d081 to d086) also displays the same error code as the inverter.

7.2 Protection function list

The table below describes an error code for protecting the inverter and the motor.
Error Display in the table below, X is 6 (Error for option slot 1) or 7 (Error for option slot 2).

No.

Function

Error

Display

Action

1

Lonworks
communication error

EX0

This error is displayed, when disconnection occured, while
the inverter is operating with Lonworks.

2

Inverter communication
error

EX9

This error is displayed, when communication timeout occurs
between the inverter and the option board.

With regard to the other errors except table above, refer to Inverter instruction manual chapter 4 Explanation

of function.

7.3 Countermeasure for a trip state

The table below only corresponds to additional trip codes, with regard to the other countermeasures refer to

Inverter instruction manual chapter 4 Explanation of function.

Trip code

Name of trip

Cause

Conformation

Countermeasure

Defective connector
for signal cable
causes connection
fail.

Check the area of
Connection.

Improve the connection and then
reset the power supply.

Terminating resistor
is not connected.

Check the
Connection

Connect the terminating Resistor
and then reset the power supply

EX0

Lonworks
Communication
error

Wiring distance does
not much with
baudrate.

Check the wiring
Distance

Adjust the setting to the matching
Baudrate
Adjust wiring distance

EX9

Inverter

error

Option board is
removed.

Check as
Mentioned left

Mount the option board again
and then secure it with screws.
