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.

CHAPTER 4 SETTING
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 SJ300/L300P the node address has to be set. This is done with the two rotary
switches(Figure 1-1) on the SJ-PB(T); 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-PB(T) 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-PB(T) supports PPO-type 1-5. (Refer to chapter 5.1 for PPO description)
The PPO type is configured from the master. The SJ-PB(T) 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 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.

SJ-PB(T) controls commands onlyNot equal to 2.1
SJ-PB(T) has no control.Not equal to 2.Not equal to 1.
However, since the SJ-PB(T) 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.

from the “Terminal” input when a SJ-PB(T) 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.

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-PB 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.

CHAPTER5 OPERATING
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-
AK: Request/response characteristics (Range 0-15)
SPM: Toggle bit for Spontaneous Messages, not used by SJ-PB(T).
PNU: Parameter number. Range 1- 418 for Hitachi specific parameters and 900-999 for Profidrive specific parameters.
Please refer to chapter 3.5 for which Profidrive specific parameters that are supported.
11
CHAPTER5 OPERATING
Request/Response handling
The AK portion of the PKE word defines the request/response that may be issued.
Since parameter length of the 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.

CHAPTER5 OPERATING
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 1-418. 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.

5.4 Parameter Examples
5.4.1 Writing a four byte parameter
In this first example, PPO1 is used to set parameter F002 (1st Acceleration time 1) to 4.00 seconds. Also, a Start
command and a frequency set-point (50%) is given.
Please note: When reading/writing parameters via the Profidrive profile the cross-reference list must be used,
see chapter 5. For example, parameter F002 (1

In the request message the first two bytes are used for parameter identification. The first digit (2) denotes the
function “Change parameter value (long word)” (refer to chapter 3.2). The second digit along with the second
byte (0 and 17) indicates parameter number 23. Bytes 7 and 8 (01 90 = DEC 400) is the parameter value (400
meaning 4.00 seconds). The last four bytes are the Control Word and Frequency set-point. Control Word value
04 06 -> 04 7F* starts the motor, while 20 00 (refer to 5.3.2) signifies 50 % of the maximum frequency specified in
parameter A004.
In the response message, the first digit (2) indicates the function “Transfer parameter value (long word)”. Value
(01 90 in bytes 7 and 8) and parameter number (x0 17) are mirrored from the request. The last four bytes are
Status Word and Actual frequency (%).
5.4.2 Writing a two byte array parameter
In this second example, we are configuring PZD3 to contain the value of parameter A038, “Jogging frequency” in
the responses from the inverter to the master (PLC). PPO2 is used. On Profibus parameter A038 corresponds
to parameter number 61 (3Dh). This is configured with parameter number 916 (394h), “Assignment of PZD read
word” (see also chapter 5.3. and 5.5).

In the request message the first two bytes are used for parameter identification. The first digit (7) denotes the
function “Change parameter value (array word)” (refer to chapter 3.2). The second digit along with the second
byte (3 and 93) indicates parameter number 916. Byte 3 (01) denotes sub-index in the array parameter, in this
case “01” means the first index in the array. Bytes 7 and 8 (00 3D = 61dec) contains the parameter number that
shall be mapped. This means that in the PZD3 place the read value of parameter A038 (Profibus parameter
number 61dec) shall be transferred from the inverter to the master every bus-cycle.
In the response message, the first digit (4) indicates the function “Transfer parameter value (array word)”. Sub-
index (01 00), value (00 3D in bytes 7 and 8) and parameter number (x3 94) are mirrored from the request. In the
PZD3 field (word 7) the value (01 F4 = 500dec, 5.00 Hz) of “Jogging frequency” is transferred.
5.4.3 Writing a two byte array parameter #2
In this third example, we are configuring PZD3 to contain the value of parameter A004, “1st Maximum frequency”
in the request from the master to the inverter. PPO2 is used. On Profibus parameter A004 corresponds to
parameter number 62 (3Eh). This is configured with parameter number 915 (393h), “Assignment of PZD write
In the request message the first two bytes are used for parameter identification. The first digit (7) denotes the
function “Change parameter value (array word)” (refer to chapter 3.2). The second digit along with the second
byte (3 and 93) indicates parameter number 915. Byte 3 (01) denotes sub-index in the array parameter, in this
case “01” means the first index in the array. Bytes 7 and 8 (00 3E = 62dec) contains the parameter number that
shall be mapped. In the PZD3 field (word 7) the value (00 4B = 75, 75 Hz) of “1
st
Maximum frequency” is
transferred. That is, parameter A004 will be written with the value 75.
In the response message, the first digit (4) indicates the function “Transfer parameter value (array word)”. Sub-
index (01 00), value (00 3E in bytes 7 and 8) and parameter number (x3 93) are mirrored from the request. As
can be seen in word 7 (PZD3) 01 F4h is transferred from the inverter to the master, that is the mapping from the
example above (5.4.2) is still present.
*To start the inverter the Profibus state machine must be shifted in a correct way. This may be done in two steps.
First the control word should be set to 04 06 (Enter
Ready to switch-on state
) and then to 04 7F (Enter Operating
state). Refer to the state diagram in Figure 5-2.

APPENDIX PARAMETER CROSS-REFERENCE LIST
Parameter cross-reference list
To be able to read/write parameters via Profibus it is necessary to use a cross-reference list to convert from
Profibus parameters to actual parameter values in the inverter.
Example, if parameter “1st Acceleration time 1” shall be read then parameter number 23 shall be used (if the
keypad is used F002 is used).
The L300P inverter supports a slightly different parameter map; the “L300P” field reflects this. “No” means
that the L300P inverter does not support the parameter, a figure means that the parameter is supported, but
