OVERVIEW

1、OVERVIEW

This chapter contains a short description of the Profibus standard and PD-301 communication expansion

card information.

1.1 Profibus standard

Profibus is an open serial communication standard that enables data exchange between all kinds of

automation components. Profibus There are three main variations of PROFIBUS: Profibus FMS (Fieldbus

Message Specification), Profibus DP (Decentralized Periphery) and Profibus PA (Process Automation).

The physical transmission medium of the bus is a twisted pair cable (according to the RS-485 standard).

The maximum length of the bus cable is 100 to 1200 meters, depending on the selected transmission rate.

Up to 31 nodes can be connected to the same PROFIBUS network segment without the use of repeaters.

With repeaters, it is possible to connect 127 nodes (including repeaters and master station) to the

network.

In PROFIBUS communication, the master station (usually a PLC) polls the nodes which respond and take

the actions requested by the master. It is also possible to send a command to several nodes at the same

broadcast; in this case the nodes do not send a response message to the master. The PROFIBUS

protocol family is specified in the EN 50170 standard. For further information on PROFIBUS, refer to the

EN 50170 standards.

1.2 PD-301 function

PD-301 is an optional communication expansion device for Shihlin new type inverter which enables the

connection of Shihlin inverter to a PROFIBUS network. The PD301 is considered as a slave on the

PROFIBUS network. Through the PD301, it is possible to:

1、give control commands to the inverter(Start, Stop, Target frequency, Forward/Reverse rotation,

etc.)

2、Send the target frequency

3、Read status information and actual values from the inverter.

4、Read and change the inverter parameter values.

5、Reset at inverter fault.

PRE-OPERATION INSTRUCTIONS

2、PRE-OPERATION INSTRUCTIONS

Please read this chapter carefully before connecting PD-301 to ensure the normal use of PD-301.

2.1 Delivery check

Each PD-301 has been checked thoroughly before delivery, and is carefully packed to prevent any

mechanical damage. The package should contain the following objects:

A PD-301;

A simple installation guide;

Two screws.

Note: If the PD-301 is different from the objects above, please contact with the agent or distributor.

INSTALLATION

3、INSTALLATION

3.1 Pre-installation instructions

Make sure that the input power of the inverter is off.

Note: With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in

option may be damaged.

3.2 Node address setting

Set the node address between "1 to 125" by using node address switches on the PD-301. For the setting

larger than 125, the address will be forced to transmitted to 125 by PD-301. When the address is 0,

Profibus slave station node address is invalid. The setting is reflected only when power turns on next time.

Please refer to the following table for address setting:

Switch number (1-8) Actual physical address

01111101~11111111

125

…… ……

00000010

00000001

00000000 0(invalid)

Note: The number is “0” when pressing the switch.

3.3 Node communication baud rate setting

PD-301 can auto detect the baud rate on Profibus without user’s setting.

4.2 Wiring

(1) Use the network connection cable which supports 12.0Mbps communication.

Strip off the sheath of the Profibus communication dedicated cable and wind wires and shield cables

to use. If the length of the sheath pealed is too long, a short circuit may occur among neighboring

wires. If the length is too short, cables and shield cables might come off.

(2) Loosen the terminal screw and insert the cable into the terminal.

Tighten each cable with fixing screws to the recommended tightening torque.

Wire the stripped cable after twisting it to

prevent it from becoming loose.

In addition, do not solder it.

Use a bar type terminal as required.

INSTALLATION

Screw size Tightening torque Cable size Screwdriver

M2 0.22N⋅m-0.25N⋅m 0.3mm2-0.75mm2

Small flat-blade screwdriver (Tip thickness:

0.4mm /tip width: 2.5mm)

Note:

After wiring, wire offcuts must not be left in the inverter. They may cause an error, failure or malfunction.

5、INVERTER SETTING

5.1 Parameter setting list

After connecting PD-301 to the inverter correctly, PD-301 can’t work immediately. User should first

confirm the parameter value below.

1: No warning and keep running. Valid

5.2 Operation mode setting

The inverter mounted with PD-301 has three operation modes.

(1) PU operation............Controls the inverter from the key of the operation panel mounted on the

inverter.

(2) External operation...Controls the inverter by switching on/off external signals connected to the

control circuit terminals of the inverter. (The inverter is factory-set to this

mode.)

(3) Network operation…Controls the inverter with instructions from the network via the communication

option.

INVERTER SETTING

Before switching the operation mode, check that:

(1) The inverter is at a stop.

(2) The P.79 Operation mode selection setting is correct.

(3) P.79 cannot be modified during communication.

5.3 Serial baud rate, communication protocol, frame format

PD-301 and the inverter adopt the Modbus format communication data. Communication speed is

9600bps, communication frame format is 1,8,N,2 (1 bit is the start bit, 8 data bits, no parity check and 2

stop bits). PD-301 is regarded as the inverter Modbus master station.

5.4 Operation at communication error occurrence

(1) Number of communication retries

P.52 is used to set the number from when a communication line error occurs until it is recognized as a

communication error. The value of P.52 determines the way of communication error displaying.

GSD FILE

6、GSD FILE

6.1 GSD file description

GSD file is designed to recognize the features and functions of Profibus-DP. GSD file is a text file which

can identify Profibus-DP device (master station or slave station). GSD file contains the necessary data

information on the standard DP master station equipped with a DP slave station. GSD file contains the

vendor information, support of communication transmission speed, timing information, support features

and accessories and available I/O signal. GSD file is the basic structure of the master station parameter

record. When editing this file, use a text editor. For installation instructions, refer to the instruction manual

of the Profibus-DP configuration software. The following is the GSD text used by PD-301 and the text

name is SEEC0D0F.GSD. User can copy the text to save it to .GSD file for use.

Also, user can download it from http://www.shihlin-elec.com/down.asp
