Chapter7 Countermeasure For Abnormality - Hitachi SJ-DN Instruction Manual

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
1 DeviceNet
communication error
2 Duplicate MACID
3 External trip
4 Inverter communication
error
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

Trip code
Error Action
Display
EX0 This error is displayed, disconnection occurs when BusOff or
timeout is occurred, while the inverter is operating with
DeviceNet. (Trip is caused by P045 and P048 setting)
EX1 This error indicates that component have the same MADID,
which exist on the same network.
EX2 This error is displayed, when Fault / Trip is set to 1 toward
control supervisor object data: Instance 1, Attribute 17.
EX9 This error is displayed, when communication timeout occurs
between the inverter and the option board.
Cause
Baud rate is different.
Wiring distance does not
match with Baud rate
Defective connector for
signal cable causes
connection fail.
Terminating resistor is
not connected.
Network power supply is
not connected. Network
power supply is out of
regulation.
Exceeding maximum
Node.
Components have the
same MACID, which are
connected on the same
network.
Class: 29Hex
Instance: 1
Attribute: 17
Option board is
removed.
COUNTERMEASURE FOR ABNORMALITY
Inverter's running condition of trip detected
Conformation
Check Baud
rate
Check the wiring
distance
Check the area of
connection.
Check the
Connection
Check the
Network power
Supply voltage
(DC11 to 24V)
Check the Node.
Check the all MACID
and also check the
component which has
the same MACID
Check as mentioned left. Set Fault/ trip to 0 toward class:
Check as mentioned left
21
Countermeasure
Install correct Baud rate and then
reset the power supply.
Adjust the setting to the matching
Baud rate.
Adjust Wiring distance.
Improve the connection and then
reset the power supply.
Connect the terminating
Resistor and then reset the power
supply
Connect Network power supply and
then reset the power supply.
Remove unnecessary components
and adjust Node to 64 (Maximum)
or under, then reset the power
supply.
Set MACID and then reset the
power supply.
29Hex, Instance: 1 and Attribute:
17.
Mount the option board again and
then secure it with screws.
