1.3 Outline of product
SJ-PB(T) is Profibus-DP communication board for SJ300/L300P series inverter.
SJ300/L300P series inverter can get to connect another devices via Profibus-DP when install SJ-PB(T).
SJ-PB(T) is possible to use for all models of SJ300/L300P series.
The SJ-PB(T) option board communicates according to the Profibus Protocol Standard DIN 19245 part 1 & 3.
This means that it can communicate with all masters that comply with this standard, but it does not necessarily
mean that all services available in the Profibus standard are supported. The “Profibus Profile for Variable Speed
Drives” (order no. 3.072), also known as Profidrive, is a subset of Profibus which only supports the services
relevant to speed control applications.
In a control system the option board will act as a slave that can be read and written to, from a Profibus-DP master.
It will not initiate communication to other nodes, it will only respond to incoming telegrams.
(Note) RS485 communication function is disabled by installing SJ-PB(T) to the inverter.
Difference between SJ-PB and SJ-PBT is only connector for networking. Others are no difference.

CHAPTER 2 INSTALLATION
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.

CHAPTER 3 WIRING, CONNECTING
3.1 Physical interface
Isolation: The bus is galvanically separated from the other electronics with an on board DC/DC converter. Bus
signals (A-line and B-line) are isolated via photo couplers.
Profibus-DP communication ASIC: VPC3 chip from ProfiChip.
Bus connection: The SJ-PB connects to the Profibus network with a 9-pin female DSUB connector. For the pin
layout, refer to Table 3-1.
Table 3-1 Pin Layout of SJ-PB
Pin Name Function
Housing Shield Connected to PE
1 Not Connected 2 Not Connected 3 B-Line Positive RxD/TxD according to RS 485 specification
4 RTS Request To Send (note)
5 GND BUS Isolated GND from RS 485 side (note)
6 +5V BUS Isolated +5V from RS 485 side (note)
7 Not Connected 8 A-Line Negative RxD/TxD according to RS 485 specification
9 Not Connected -
(note) +5V BUS and GND BUS are used for bus termination. Some devices, like optical transceivers (RS485 to
fibre optics) might require external power supply from these pins. RTS is used in some equipment to determine
the direction of transmission. In standard applications only A-Line, B-Line and Shield are used.
The SJ-PBT connects to the Profibus network with a 6-poles 2pieces connector. For the pin layout, refer to
Table 3-2.
Table 3-2 Pin Layout of SJ-PBT
Pin Name Function
1 B-Line(in) Positive RxD/TxD according to RS 485 specification
2 A-Line(in) Negative RxD/TxD according to RS 485 specification
3 Shield Connected to PE
4 B-Line(out) Positive RxD/TxD according to RS 485 specification
5 A-Line(out) Negative RxD/TxD according to RS 485 specification
6 Shield Connected to PE
3.2 Profibus connectors
On the SJ-PB, any standard Profibus connector can be used. Depending on baudrate, IP-classing and physical
size of connector there are several different manufacturers and models, the prizing may also vary. For more
information it is recommended to contact the manufacturer, e.g., Siemens or Erni.
SJ-PBT: In this case, the network connector is attached with SJ-PBT option board.

CHAPTER 3 WIRING, CONNECTING
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.A terminating resistor is not built-in the unit. Please provide it.
5.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.
6.Basic components for construction of Profibus-DP application are shown bellow.
Refer to the master’s description manuals when Profibus-DP Network system comes into operation.
