PREFACE

Thank you for your choice of EURA DRIVES SoftStarter.

As the return of your trust we will provide the perfect quality and wholehearted service to you.

HFR2000 adopts three input wires and six output wires design, with output current token function, and on-line monitoring motor current, to realize motor over-load protection. The jogging control function can be used in worksite debugging. Air cooling design ensures system stable running. It is characteristic of convenient connection, smooth starting and motor protection and is widely applicable for starting and protection of three-phase motors in various industries.

Notes

This instruction manual provides information with respects to installation, parameter-setting, trouble-diagnosing and proper operation. This manual should therefore be kept properly and a careful reading shall be required before any operation attempt to avoid any accidental casualties or damage(s) to the facilities.

Special Notice:

Installation, operation, maintenance or checking to this product shall be required before reading carefully this instruction manual and ensuring proper use.

Power shall be disconnected before any wiring. Never touch power terminal with hand or conduct object. Never put or drop foreign substance into soft starter.

When using the bypass contactor, please connect the motor according to the recommended diagram in the user‟s manual, that‟s

EURA Soft Starter User’s Manual in order to keep the output exact consistency of softstarter and motor. Otherwise softstarter and motor will be damaged.

Please do not take magneto ohmmeter to measure the insulated resistance between input and output. Otherwise the IGBT and control PCB will be damaged because of high voltage. Please use the magneto ohmmeter to measure the resistance between each phase and between each phase with ground. Also please note that firstly use 3 cables short circuit the each three-phase of input and output separately and take out the entire plugs in control PCB.

Connect input terminals R, S and T to urban power supply of

400V, connect output terminals U, V and W to motor.

Grounding terminal PE shall be properly earth connected

(grounding impedance not exceeding 4Ω).

When terminals R, S and T are connected to power supply of

400V and output terminals U, V and W are not connected to motor, it is normal that the voltage of U, V and W is AC400V. The voltage is got by leakage current of module. After U, V and W are connected to motor, the voltage will clear away.

Capacitance can not be connected to the output of soft starter, but capacitance can be connected to the input of soft starter when it is used for improving power factor.

Functional Block Diagram

3.1 Functional Block Diagram

Three reverse-parallel connection SCR modules are adopted as power element. By picking up synchronization signal from input voltage sampling, it can pick up output current sampling for feedback fuzzy control, trace the phase automatically and control phase displacement angle. Voltage can thus be increased step by step, and startup current will be under control. After startup, the bypass contactor will make the SCR short circuit.

The motor will finally be driven into the electricity network for operation.

Appendix 4 Communication Manual

(Modbus Version 1.7)

I. General

Modbus is a serial and asynchronous communication protocol. Modbus protocol is a general language applied to PLC and other controlling units. This protocol has defined an information structure which can be identified and used by a controlling unit regardless of whatever network they are transmitted.

Modbus protocol does not require a special interface while a typical physical interface is RS485.

You can read reference books or ask for the details of MODBUS from manufactures.

II. Modbus Protocol

1. Overall Description

(1) Transmission mode

1) ASCII Mode

When controllers are setup to communicate on a Modbus network using ASCII mode, each 8–bit byte in a message is sent as two ASCII characters.

For example, 31H

(hexadecimal data) include two ASCII characters‟3(33H)‟,‟1(31H)‟.

Common characters, ASCII characters are shown in the following table:

Characters

„7‟

„F‟

ASCII Code

2) RTU Mode

38H 39H 41H 42H 43H 44H 45H 46H

In RTU mode, one Byte is expressed by hexadecimal format. For example, 31H is delivered to data packet.

(2) Baud rate

Parity Check Bit (None for this bit in case of no checking. Otherwise 1 bit)

(4) Error Check

1) ASCII mode

Longitudinal Redundancy Check (LRC): It is performed on the ASCII message field contents excluding the „colon‟ character that begins the message, and excluding the CRLF pair at the end of the message.

The LRC is calculated by adding together successive 8–bit bytes of the message, discarding any carries, and then two‟s complementing the result.

A procedure for generating an LRC is:

1. Add all bytes in the message, excluding the starting „colon‟ and ending CRLF. Add them into an 8–bit field, so that carries will be discarded.

2. Subtract the final field value from FF hex (all 1‟s), to produce the ones–complement.

3. Add 1 to produce the twos–complement.

2) RTU Mode

Cyclical Redundancy Check (CRC): The CRC field is two bytes, containing a 16–bit binary value.

The CRC is started by first preloading a 16–bit register to all 1‟s. Then a process begins of applying successive 8–bit bytes of the message to the current contents of the register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and the parity bit, do not apply to the

CRC.

A procedure for generating a CRC-16 is:

1. Load a 16–bit register with FFFF hex (all 1‟s). Call this the CRC register.

2. Exclusive OR the first 8–bit byte of the message with the high–order byte of the 16–bit CRC register, putting the result in the CRC register.

3. Shift the CRC register one bit to the right (toward the LSB), zero–filling the MSB. Extract and examine the LSB.

4. (If the LSB was 0): Repeat Step 3 (another shift).

(If the LSB was 1): Exclusive OR the CRC register with the polynomial value A001 hex (1010 0000 0000

0001).

5. Repeat Steps 3 and 4 until 8 shifts have been performed. When this is done, a complete 8–bit byte will have been processed.

When the CRC is appended to the message, the low-order byte is appended first, followed by the high-order byte.

It is easy to turn a RTU command into an ASCII command followed by the lists:

1) Use the LRC replacing the CRC.

2) Transform each byte in RTU command into a corresponding two byte ASCII. For example: transform 0x03 into 0x30, 0x33 (ASCII code for 0 and ASCII code for 3).

3) Add a „colon‟ ( : ) character (ASCII 3A hex) at the beginning of the message.

4) End with a „carriage return – line feed‟ (CRLF) pair (ASCII 0D and 0A hex).

So we will introduce RTU Mode in followed part. If you use ASCII mode, you can use the up lists to convert.

(3) Address and meaning

The part introduces softstarter running, softstarter status and related parameters setting.

Description of rules of function codes parameters address:

1) Use the function code as parameter address

1. General Series:

High-order byte: 01~09 (hexadecimal)

Low-order byte: 00~3C

For example: F114 (display on the board), parameter address is 010E (hexadecimal).

2. Softstarter series

High-order byte: 00

Low-order byte: 00~3C

For example: HF14 (display on the board), parameter address is 000E (hexadecimal).

Note: in this situation, it allows to read six function codes and write only one function code.

Some function codes can only be checked but cannot be modified, some function codes can neither be checked nor be modified, some function codes can not be modified in run state, some function codes can not be modified both in stop and run state.

In case parameters of all function codes are changed, the effective range, unit and related instructions shall refer to user manual of related series of softstarters. Otherwise, unexpected results may occur.

2) Use different parameters as parameter address

Please note that for the same time in half-duplex connection, only one softstarter can have communication with PC/PLC. Should two or more than two softstarters upload data at the same time, then bus competition will occur, which will not only lead to communication failure, but higher current to certain elements as well.

No direct grounding shall be allowed for any point of RS485 network. All the equipment in the network shall be well grounded via their own grounding terminal. Please note that grounding wires will not form closed loop in any case.

Please think over the drive capacity of PC/PLC and the distance between PC/PLC and softstarter when wiring. Add a repeaters if drive capacity is not enough. Modbus repeaters may be used to extend the length of the loop, but introduce delay in the device response time. Using repeaters on slow devices may cause timeout problems.

All wiring connections for installation shall have to be made when the softstarter is disconnected from power supply.
