1.3 Outline of product
SJ-PB2/SJ-PBT2 is Profibus-DP communication board for SJ700/SJ300/L300P series inverter.
SJ700/SJ300/L300P series inverter can get to connect another devices via Profibus-DP when install
SJ-PB2/SJ-PBT2.
SJ-PB2/SJ-PBT2 is possible to use for all models of SJ700/SJ300/L300P series.
The SJ-PB2/SJ-PBT2 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-PB2/SJ-PBT2 to the inverter.
Difference between SJ-PB2 and SJ-PBT2 is only connector for networking. Others are no difference.

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: NP30 chip from ProfiChip.
Bus connection: The SJ-PB2 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-PB2
Pin Name Function
Housing Shield connection to PE(note 2)
1 Not Connected -
2 Not Connected -
3 B-Line Positive RxD/TxD according to RS 485 specification
4 RTS Request To Send (note 1)
5 GND BUS Isolated GND from RS 485 side (note 1)
6 +5V BUS Isolated +5V from RS 485 side (note 1)
7 Not Connected -
8 A-Line Negative RxD/TxD according to RS 485 specification
9 Not Connected -
(note 1) +5V BUS and GND BUS are used for bus termination. Some devices, like optical transceivers (RS485
to fiber 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-PBT2 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-PBT2
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 connection to PE(note 2)
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 connection to PE(note 2)
(note 2) There is no PE connection on the SJ-PB2/SJ-PBT2 option board. For proper grounding the shield of
the bus cable should be grounded by clamping it to a metal surface connected to PE. It’s important that the
shield is grounded in order to avoid noise problems.
3.2 Profibus connectors
On the SJ-PB2/SJ-PBT2, 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-PBT2: In this case, the network connector is attached with SJ-PBT2 option board.

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.In order to avoid noise problems, the shield of the bus cable should be grounded by clamping it to a metal
surface connected to PE for proper grounding. Refer to Figure.3-1.
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.

4.1 Profibus Configuration
Follow the procedure below to set Baud rate in Profibus-DP and Node Address, reset the power supply after
changing the setting (setting will be reflected after resetting power supply). Initial Node Address: 0, Initial Baud
rate: According to master’s setting.
4.1.1 Node Address
Before power-on the SJ700/SJ300/L300P the node address has to be set. This is done with the two rotary
switches(Figure 1-1) on the SJ-PB2/SJ-PBT2; this enables address settings from 0-99 in decimal format. The
right rotary switch at the top of the option board represents a times ten factor. The rotary switch at the left
represents one to nine. For example, if address 27 shall be set: Set the right rotary switch to two and the left
rotary switch to seven.
Address = (Right Switch Setting x 10) + (Left Switch Setting x 1)
(Note) The node address cannot be changed during operation; the module needs to be re-powered in order for
the change to have effect.
4.1.2 Baudrate
The baudrate on a Profibus-DP network is set during configuration of the master and only one baudrate is
possible in a Profibus-DP installation. The SJ-PB2/SJ-PBT2 has an auto baudrate detection function and the
user does not have to configure the baudrate on the module. Refer to 4-1 for the baudrates supported.

4.1.3 PPO-type selection
The SJ-PB2/SJ-PBT2 supports PPO-type 1-5. (Refer to chapter 5.1 for PPO description)
The PPO type is configured from the master. The SJ-PB2/SJ-PBT2 senses the configuration and configures itself accordingly. The
amount of input/output data transferred on the Profibus network depends on the selected PPO type. Amount of data transferred in the
data-exchange telegram is ranging from 4 bytes input/output (PPO3) to 28 bytes input/output (PPO5).

CHAPTER 4 SETTING

4.2 Setting of controlling frequency and start/stop commands
The SJ700/SJ300/L300P inverters can be configured to take reference set-points and commands from several
different locations. Refer to the table below for information of how to configure the inverter so that the fieldbus
controls frequency and the commands.
Control Frequency Setting
Selection - A001 Operation Setting Selection - A002
SJ-PB2/SJ-PBT2 controls frequency and commands 2 1
SJ-PB2/SJ-PBT2 controls frequency only 2 Not equal to 1.
SJ-PB2/SJ-PBT2 controls commands only Not equal to 2. 1
SJ-PB2/SJ-PBT2 has no control. Not equal to 2. Not equal to 1.
However, since the SJ-PB2/SJ-PBT2 module uses the “Terminal” to give commands and “Operator” to give
references to the inverter certain steps must be taken in order to be able to control the inverter manually (not
from fieldbus). Study the table below to see how the control word bits shall be set to accomplish control from
fieldbus and from the user.
Control word bit settingsControlling the inverter with
A001 = 2 (Operator),
A002 = 1 (Terminal). 10 12 13
SJ-PB2/SJ-PBT2 controls frequency and commands 1 0 0
SJ-PB2/SJ-PBT2 controls frequency only* 1 1 0
SJ-PB2/SJ-PBT2 controls commands only 1 0 1

SJ-PB2/SJ-PBT2 has no control. 0 - -
from the “Terminal” input when a SJ-PB2/SJ-PBT2 is present in the option slot. In order to do this, bit ten in the
Control Word shall be set to zero. That is, by setting A001=2, A002=1, and control word bit 10=0 it is possible to
control the inverter with the terminal while giving frequency reference from the fieldbus.
*Please note that when frequency reference is controlled from the fieldbus and commands from another location
(such as “Terminal”) the direction of the motor must be controlled from the command source (Reverse/Forward
command). In this case changing the sign of reference value cannot control the direction of the motor.
4.3 Action at communication error
In case of occurring transmission errors (communication cut-off with the master), the following actions can be
selected.
Depending on what option slot the option module is connected to, P001 (Option 1) or P002 (Option 2) is
changed.
P001/P002
Action at error detection Remarks
0 Inverter will trip. Option trip E6x or E7x. Fault can be reset either from
fieldbus or from keypad.
1 Continue operation according to the last
received command. - -

CHAPTER5 OPERATING

This section describes how to control the inverter via control word/status word and how to access the inverters
parameters.
5.1 PPO- description
The structure of the user data is designated as parameter process data objects (PPO) in the Profidrive profile.
The profile defines five PPO types, where SJ-PB2/SJ-PBT2 supports all these PPO types.
There are PPO’s with a parameter area (PKW) and a process data area (PZD). There is also PPO’s that consist
exclusively of process data (PZD).
1. PPO1 consists of the PKW area and 2 words PZD.
2. PPO2 consists of the PKW area and 6 words PZD.
3. PPO3 consists only of 2 words PZD.
4. PPO4 consists only of 6 words PZD.
5. PPO5 consists of the PKW area and 10 words PZD.
The user can configure what shall be transferred in PZD3-10 (shaded grey below), for more instructions of how
to do this configuration see chapter 5.3.3, 5.4.2, 5.4.3 and Appendix.

5.2 PKW-part
The parameter part (PKW) is fixed to 4 words and can be used for reading and/or updating the parameters in
the inverter one by one. Requests and responses is a handshake procedure and cannot be batched, meaning
that if the master sends out a read/write request, it has to wait for the response, before it sends a new request.
The PKW is further divided into three parts; PKE- Parameter ID (2 bytes), IND – Sub-index (2 bytes) and PWE-
Parameter value (4 bytes).

Request/Response handling
The AK portion of the PKE word defines the request/response that may be issued.
Since parameter length of the SJ700/SJ300/L300P inverter may vary, parameter values are always transferred
so that the least significant byte is placed in octet 8.
If the Request/Response contains array elements, the high byte (byte 3) of the IND word will carry the array sub
index, low byte (byte 4) is reserved for future use.

5.3 PZD-part
In this chapter the process data part (PZD) of a PPO is discussed.
The PZD part consists of a fixed part (PZD1-2, all PPO’s) and a parameterable part (PZD 3-10, shaded grey
above, PPO 2, 4 and 5).
In the fixed part, control word and speed reference are transferred to the inverter while status word and actual
output frequency are transferred from the inverter.
In the parameterable part, PZD word 3-10, the user can configure what parameters that should be transferred
to/from the inverter every bus-cycle (see chapter 5.3.3 and Appendix).
5.3.1 Control- / status word (STW/ZSW)
This section describes how to operate the inverter with the control-/status word. With the control word the
Profidrive state-machine (Figure 5-2) is controlled, the status word is reflecting the state of the inverter.
Profidrive Control Word (STW):
The control word is used to send control commands to the inverter (PLC->Inverter).

5.3.3 PZD word 3-10
In PZD word 3-10 the user can determine which inverter parameters that should be transferred to/from the
inverter every bus-cycle.
With some of the PPO types (PPO2, 4, 5) it is possible to read and write parameters cyclically. Parameter write
values are placed in the PZD’s 3-10 transferred from the master to the inverter. Parameter read values are
placed in the PZD’s 3-10 transferred from the inverter to the master. However, the meaning of the data
transferred in PZD3-10 must be defined in some way so that it can be determined what parameters that shall be
written, and also so that the data transferred from the inverter can be connected with the correct parameter.
Parameter 915 and 916 are used to determine what parameters that shall be written (915) and read (916)
cyclically (parameter number as specified below, for examples of how to assign these refer to chapter 5.4.2 and
5.4.3).
Assignment of PZD write word 3-10 (PLC -> Inverter) with parameter 915:
915, sub-index 1 = Parameter number for parameter transferred in PZD3
915, sub-index 2 = Parameter number for parameter transferred in PZD4
915, sub-index 3 = Parameter number for parameter transferred in PZD5
915, sub-index 4 = Parameter number for parameter transferred in PZD6
915, sub-index 5 = Parameter number for parameter transferred in PZD7
915, sub-index 6 = Parameter number for parameter transferred in PZD8
915, sub-index 7 = Parameter number for parameter transferred in PZD9
915, sub-index 8 = Parameter number for parameter transferred in PZD10
Assignment of PZD read word 3-10 (Inverter ->PLC) with parameter 916:
916, sub-index 1 = Parameter number for parameter transferred in PZD3
916, sub-index 2 = Parameter number for parameter transferred in PZD4
916, sub-index 3 = Parameter number for parameter transferred in PZD5
916, sub-index 4 = Parameter number for parameter transferred in PZD6
916, sub-index 5 = Parameter number for parameter transferred in PZD7
916, sub-index 6 = Parameter number for parameter transferred in PZD8
916, sub-index 7 = Parameter number for parameter transferred in PZD9
916, sub-index 8 = Parameter number for parameter transferred in PZD10
Please Note:
1. PZD words 3-6 are enabled if PPO 2 or 4 is selected. PZD words 3-10 are enabled with PPO5.
2. Parameter numbers are within the range 1-596. See chapter 5 for an index of the inverter parameter numbers.
If a parameter number is set to 0, the actual PZD word will be ignored.
3. Only parameters that are of size two bytes or less can be assigned as PZD objects.
