1. Overview

Thank you for using HV610 series inverter and choosing HV610-DP card!

The HV610-DP card is a Profibus-DP fieldbus adapter card, which conforms to the internationally

accepted Profibus fieldbus standard. The card is installed on the HV610 inverter to improve

communication efficiency and facilitate the networking function of the inverter. Make the inverter a

slave of the fieldbus and accept the control of the fieldbus master.

HV610-DP card can realize Profibus-DP communication.

Please read this manual carefully before using this product.

2. Installation and wiring

The HV610-DPcard is designed to be used in HV610 series inverters. Please turn off the power

supply to the inverter before installation. Wait for about 10 minutes before the inverter's charging

indicator goes out before installation. After the HV610-DP card is inserted into the inverter, please

fix the corresponding screws to prevent the signal socket between the boards from being damaged

by the external signal cable.

3. DP card and HV610 inverter communication configuration instructions

After the HV610-DP card is correctly installed on the HV610 inverter, the relevant communication

configuration needs to be completed before the DP card can establish communication with the

inverter.

Inverter communication card type setting

The function code Fd-00 needs to be set to 1, and Profibus-DP is selected as the serial

communication protocol of the inverter, as shown in the following table.

4. DP card and Profibus master communication configuration instructions

After the DP card communicates with the HV610 inverter, it needs to be correctly wired with the

Profibus master station. Setting the relevant communication configuration can realize the

communication between the DP card and the Profibus master station, thereby achieving the

inverter networking function.

Wiring of DP card and Profibus master

The connection diagram between the DP card and the Profibus master station is shown below:

Figure 3 Schematic diagram of the connection between the DP card and the Profibus master station

In the Profibus bus terminal, it is necessary to access the terminal matching resistor, and the dialing

code can be dialed according to the indication on the terminal. The PE level of the system must be

reliably grounded.

(86)

According to the setting of the communication baud rate of the master station, the length of the

communication cable between the DP card and the Profibus master station is also required. The

length of the communication data cable must be restricted in strict accordance with the SIEMENS

DB9 wiring standard.

The baud rate and wire length requirements are shown in the following table:

HV610 Profibus-DP slave address configuration

To realize the function of Profibus master-slave control inverter, HV610 Profibus-DP communication

slave address must be set. The slave address can be set by the DIP switch on the DP card, or by

the inverter function code Fd-03. The slave address of the HV610-DP card is set by the 3 to 8 bits

of the DIP switch, as shown in the following table:

Communication timeout detection setting

In order to determine whether the communication between the HV610-DP communication card and

the master station is interrupted, it is necessary to set the function code communication timeout

period (Fd-05). If the interval between one communication and the next communication exceeds

the communication timeout time, the inverter will report a communication failure error (COF).

PPO data format selection

The PPO type is used as the data transmission format in the PROFIDRIVE (variable speed drive)

protocol. For details, see the description of the data format definition in the subsequent

communication protocol section. HV610 Profibus-DP protocol supports 4 data formats, PPO1,

PPO2, PPO3, PPO5 are set by the ten digits of the function code Fd-06, as shown in below table:

After the above information is configured, the inverter needs to be powered on again to take effect.

5. Profibus-DP communication protocol description

Data transfer format

In the PROFIDRIVE protocol, the PPO type is used as the data transmission format. There are five

types of PPO types: PPO1, PPO2, PPO3, PPO4, and PPO5. The HV610-DP card supports four

types of data formats: PPO1, PPO2, PPO3, and PPO5.

The functions that each data format can complete are as follows:

(86)

Data type

Function

Data type

Function

PPO1

◆ Single function parameter operation

PPO3

◆ Inverter command, frequency control

◆ Inverter status, running frequency reading

PPO2

◆ Single function parameter operation

PPO5

◆ Single function parameter operation

◆ Inverter command, frequency control

◆ Inverter status, running frequency reading

◆ 4 function parameters are written periodically

◆ 10 function parameters are written periodically

◆ 4 function parameters are be read periodically

◆ 10 function parameters are be read periodically

The data block contained in the PPO type data format is divided into two areas, namely the PKW

area (parameter area) and the PZD area (process data area). The HV610-DP card supports four

types of PPO data formats as shown below:

Figure 4 PPO type data format description

PKW area data description

The data in the PKW area mainly implements the reading and writing of the single function code of

the inverter by the master station, and the communication address of the inverter function code is

directly given by the communication data. The functions implemented are as follows:a) Read the

function parameters of the inverterb) Change of inverter function parameters.

◆ Data format

The data in the PKW area contains three sets of array areas, namely PKE, IND, and PWE. The

PKE data byte length is 2 bytes, IND is 2 bytes, and PWE is 4 bytes. The data format is shown in

the following table:

◆ Application examples

The master station reads the send data PKW area of the inverter function parameter F0-09 and the

drive response data PKW area as shown below:

Figure 5 Example of master station reading inverter parameters and sending PKW data

(86)

The master station changes the send data PKW area of the inverter function parameter F0-09 and

the inverter response data PKW area as shown below:

Figure 6 Example of master station writing inverter parameters and sending PKW data

The PKW data will interact with the inverter in a cyclic execution manner. If you use a write

command (PKE = 0x20xx) to continuously operate the EEPROM, the life of the inverter's main

control chip will be greatly reduced. If you need to change the parameters of the inverter's function

code, it is recommended to use PKW In the operation of the RAM address, the corresponding RAM

address of the function code F0 ~ FF group is 0x00 ~ 0x0F; the corresponding address of the A0 ~

AF group is 0x40 ~ 0x4F. For example, the corresponding RAM address of F0-10 is 0x000A.

PZD area data description

The data in the PZD area enables the master station to change and read the inverter data in real

time and perform periodic data interaction. The communication address of the data is directly

configured by the inverter. It mainly includes the following:a) Inverter control command and target

frequency given in real timeb) Real-time reading of inverter's current status and operating

frequencyc) Function parameter and monitoring parameter data real-time interaction between

inverter and PROFIBUS master stationThe PZD process data mainly completes the periodic data

exchange between the master station and the inverter. The interaction data is as follows:

◆ Master sends data description

PZD1 and PZD2 are fixed configurations and cannot be modified by the user. PZD3 ~ PZD12 are

user-defined periodic data interactions, corresponding to the HV610 series inverter FE group

function code parameters. This group of parameters are user-defined parameters. The master

station sends data PZD3 ~ PZD12 corresponding to FE-00 ~ FE-09, and the inverter response data

PZD3 ~ PZD12 corresponds to FE-10 ~ FE-19. Modify the setting value of the FE group parameter

to exchange data with the master station. Setting the FE group parameter value to F0.00 means

skipping the data area.

◆ Application examples

The master station periodically change the inverter's function parameter F0-09 through PZD3:

1. Enter FE-00, the initial keyboard display is shown in the figure:

2. Modified to F0-09, the keyboard display is as follows:

3. The master station periodically change the F0-09 function code by filling PZD3 data (do not write

EEPROM):

The master station periodically reads the inverter’s function parameter U0-06 through PZD3:

1. Enter FE-10. The initial keyboard display is shown in the figure.

2. Modified to U0-06, the keyboard display is as follows:

3. The master station reads the PZD3 data to realize U0-06: periodic reading output torque.

(86)

6. Configure GSD on the S7-300 master

When using the PROFIBUS master, you must first configure the .GSD file of the slave so that the

corresponding slave device is added to the system of the master .GSD files can be obtained from

HNC agents or manufacturers. The specific operations are as follows:

1. Build a project in STEP7, add the S7-300 master station to the project, as shown below:

2. Double-click the hardware logo to enter the HW config configuration, and add the

MD38PFS.GSD file in the HW config configuration screen, as follows:

(86)

3. Click Install. After the installation is completed, there will be a PROFIBUS-DP module of

MD38PFS in the system.

4. The actual hardware system of the configuration system is shown below:

5. Configure the data characteristics of the slave:

All the above operations complete the operation of the PROFIBUS slave. You can control the

inverter by writing the corresponding program in S7-300.
