1.3 Outline of product
SJ-DN is DeviceNet communication board for SJ300/L300P series inverter.
SJ-DN conforms to open field Network DeviceNet and it activates as slave function (Group 2 only server).
SJ-DN is also conforms ODVA’s certification.
(SJ-DN has been tested by ODVA's authorized Independent Test Lab and found to comply with ODVA
Conformance Test Software Version A-13.)
The following functions are available via DeviceNet communication function by installing SJ-DN to
SJ300/L300P series.
Polled Input/Output message connection
This command can exchange the master’s I/O data for the slave (Inverter)’s I/O data.
Output data (from master to SJ-DN):
Run/Stop, reference frequency, Acceleration time, Deceleration time, Fault reset etc.
Input data (from SJ-DN to master):
Inverter status, output frequency, output current, trip history etc.
Explicit message connection
This function can reads and writes (configuration) the inverter’s parameter data, when it is necessary.
SJ-DN can use inverter below:
SJ300-004LF to 550LF, 007HF to 550HF, L300P-110LFR to 750LFR, 110HFR to 750HFR
(Note) RS485 communication function is disabled by installing SJ-DN to the inverter.

2.1 Mounting method of option board
Figure 2-1 describes how to mount the option board to the option port 1 or 2.
There are four holes on the option board, match the two of them with the screw holes on the option port 1 or 2.
and mount the other two holes with the guide posts which are located on the option port 1 and 2. To avoid
connection failure, secure the option board with screws after connection.

3.3 Wiring note
1.Installing / removing the cable or connector must be done after checking the power supply off.
2.Wiring should not have bare cables exposed between connector contacts.
3.Network cables should be fixed without tension. Cables fixed under tension have potential of causing a
communication fault by to be removed a connector.
4.Provide a communication power source (DC24V).
5.A terminating resistor is not built-in the unit. Please provide it.
6.Ensure external emergency stop measures are taken to stop the inverter, in the event of a network fault.
(a) Remove the Power supply of the Inverter when the network master detects a communication fault.
(b) When the master detects a communication fault, turn on the intelligent input terminal which would be
allocated (FRS), (RS) and/or (EXT) function.
(c) Setting command P045 to except “02”.
In this setting, the inverter is tripped, deceleration or free run stop when it detects a communication
fault itself. (Factory initialization of command P045 is trip after deceleration stop (code: 01).)
See “4.2 Setting of the Inverter”and “4.3 Explanation of additional parameters”about explanation of
P045 (Inverter action when communication error).
7.Basic components for construction of DeviceNet application are shown bellow.
Refer to the master’s description manuals when DeviceNet Network system comes into operation.
