B. 1 Summarization

We provide the customer with general RS485/RS232 communication interface in

our EN500/EN600 series frequency inverter. For the users, through the

communication interface upper device (such as PC, PLC controller etc.) can

perform centralized monitor to the inverter (such as setting inverter parameter,

controlling run of inverter, reading work state of the inverter) and also

long-distance control keypad can be connected to realize diverse operating

requirement of the user.

This communication protocol is interface criterion file designed for realizing

above-mentioned function, please read it earnestly and program according to it so

that realize long-distance and network control to the inverter.

B.2.2 Communication mode

At present, EN500/EN600 inverter can be used as not only auxiliary device but

also mainframe device in RS485, if the inverter is used as auxiliary device,

master device can be completed by PC, PLC or human interface, and if used as

mainframe device, the main- auxiliary control of the inverter can be complement

by it, Specific communication mode is as mentioned below:

(1) PC or PLC as mainframe, inverter as auxiliary device, point-to-point

communication between mainframe and auxiliary device.

(2) Auxiliary device don’t response when mainframe send out command by

broadcast address.

(3) User can set local address, baud rate and data format of the inverter through

auxiliary device keypad.

239

Appendix B Free-port communication protocol

(4) Auxiliary device report current failure information to mainframe in the last

response frame.

(5) EN500/EN600 provides RS485 interface.

B.2.3 Transport mode

Asynchronous serial, semiduplex transport mode. Default format and transport

rate: 8-N-1, 9600bps.For specific parameter setting please see description for F05

Remark:

(1) “Setting data area” and “run data area” may not be existent in some

command/data frame format, so in protocol command list it’s marked with

“nothing”.

(2) In protocol effective character set is: ~,

A, B, C, D, E, F and hex data 0DH, ASCII lowercase a, b, c, d,

e, f are invalid.

(3) Effective command frame length is 14 or 18 byte.

B.2.5 Explanation and description for format

(1) Frame head

It’s character“~” (namely hex 7E), single byte.

(2) Auxiliary device address

Data meanings: local address of auxiliary device, double byte. ASCII format.

Inverter factory default is 01.

(3) Mainframe command/auxiliary device respond

Data meanings: mainframe send out command and auxiliary device respond to the

command. Double byte, ASCII format.

Response code function classification:

Species 1>: command code=“10”, mainframe ask auxiliary device to report

current preparation state and control situation.

The maximum electric distance between keyboard EN-LED1, EN-LED2,

EN-LCD1, EN-LED3-D and local inverter is 2m.

RS485 communication mode is adopted between inverter and remote keyboard

EN-LCD2, only an ordinary cable is needed to connect each other, and their

maximum electric distance can be 1000m. When the communication with each

other is main-auxiliary mode, namely take remote keyboard as main device and

inverter as auxiliary device. The terminals of the connection cable are made by

crystal ends, so it is easy to maintain. Power needs customers’ outer leading，the

voltage range is from 10V to 24V，the demand current is 150mA，1mm²of PVC

insulate copper wire is suggested to connect.

Following function can be realized by remote keyboard:

(1) Can control run, stop, jog, failure reset, change setting frequency, modify

function parameter and run direction of auxiliary device.

(2) Can identify the type of auxiliary device. Can monitor the running frequency,

setting frequency, output voltage, output current, analog closed loop feedback,

analog closed loop setting and exterior counting value of auxiliary device.

D.2.1 PROFIBUS introduction

(1)PROFIBUS (short for Process Field Bus ),PROFIBUS is an international and

open field bus standard independent with manufacturer. It can be support for

many equipment manufacturers, with good compatibility. It’s widely used in

Manufacturing Automation, automation of process industry, and other buildings,

transportation, electric power automation field.

(2)PROFIBUS can realize exchanging the data between all kinds of element of

automation, all of this equipment can exchange the information though the same

port. But the transmission rate is different .all the automatic equipment can

exchange the information though the same port, but with the different rates, so

PROFIBUS should offer different types for the speed rates selection. it is made up

with PROFIBUS-DP(Distributed peripheral ),

PROFIBUS-PA,PROFIBUS-FMS.

(3)PROFIBUS (RS485), the first layer realize the balanced data transmission,

wire a bus segment one Bus segment is shielded twisted pair cable, both ends of

the segments have a terminating resistor. Transmission mode to half duplex,

asynchronous, synchronous gap-free data exchange basis, the physical layer

supports fibre, the data frame 11, and the transfer rate: 9.6Kbit / sec-12Mbit / sec.

Bus length range from 100 to 1200 meters

(4)Between same-level controller and PC communications

(token passing

procedure), to ensure adequate opportunity to deal with their communication tasks

in a determined time. Complex PLC and PC with a simple division formula I / O

communications, you must quickly and with minimal protocol overhead (master -

slave program)

D.3 CANopen communication card

D.3.1 CANopen introduction

CANopen is an architecture in the control area network (Controller Area Network,

CAN) on the high-level communication agreements, including communication

equipment sub-sub-agreements and agreements, often used in embedded systems,

industrial control is a commonly used fieldbus. CANopen implements the network

layer and above the agreement OSI model. CANopen standard includes

addressing scheme, several small communication sub-agreements

D.3.2 Equipment model

Communication agreement on other modules communication processing and

network communication unit needed to start and reset the device has a state

machine control. State machine include: Initialization, Pre-operational,

Operational, Stopped.

D.3.3 Object Dictionary

Object Dictionary (OD: Object Dictionary) is an ordered group of objects; each

object using an index value of 16 is addressed, in order to allow access to the data

structure of a single element, while the definition of an eight sub-indexes.

D.3.4 Communication

(1)Communication objects: Management packets, Service Data Objects (SDO),

process data objects (PDO), the pre-definition packet or special function object

(2)Communication model: master/slave model, client/server model,

producer/consumer model

D.3.5 Agreement

(1) NMT Agreement

(network management, network management): Status

Agreement definition of the state machine change commands (such as starting or

stopping the equipment), to detect remote device bootup and failure scenarios.

(2) Heartbeat Agreement: nodes in the network to monitor and confirm it is

working properly.

(3) SDO agreement: between devices used to transfer large low-priority data,

typically used to configure devices on the CANopen network.

(4) PDO Agreement: 8 bytes or less used to transmit data, no other agreement

preset (which means data has been pre-definition).

compared with CANOPEN card, with high transmission efficiency, real-time,

stability and other characteristics, the maximum transfer rate of 1Mbps. CAN bus

data transmission using a differential signal, with strong anti-interference,

transmission distance and other characteristics, the communication rate 5Kbps

below, the farthest reach 10Km, at 1Mbps baud rate up to 30m.

Appendix F Braking unit and braking resistance

F.1 Braking unit and braking resistance

The motor’s electric potential energy will charge inverter’s capacitance up

reversely if speed of the motor descends too quickly or load of the motor wobbles

too quickly while the inverter is running, which will increase the voltage upon

power modules suddenly and is easy to make the inverter damaged. The inverter

will control it according to load size and performance. You only need to connect

external braking resistance to realize timely energy discharge when the braking

function is needed. To connect external resistance is a kind of energy consumption

braking mode, as all the energy is consumed by the braking resistance.

EN600-2S0037, EN600-4T0007G/0015P ～ EN600-4T0150G/0185P has been

configured the built-in braking unit for EN600-2S0004 ～ EN600-2S0022,
