Chapter 1 Safety Information

1.1 Danger And Warning Definitions

Danger

Operations without following instructions can cause personal injury or death

Attention

Operations without following instructions can cause personal injury or damage to product or other equipment.

1.2 Notes For Installations

Danger

Please install the drive on fire-retardant material such as metal.

Keep the drive away from combustible materials.

Keep the drive away from explosive gas.

Only qualified personnel shall wire the drive.

Note that the control terminal of EV1000 drive is of ELV (Extra Low Voltage) circuit, therefore, do not connect the control terminal with other devices directly. For example, before connecting the RS485 terminal with the PC’s RS232 terminal, an adapter with isolating protections must be connected in between;

Never wire the drive unless the input AC supply is totally disconnected; otherwise, there is danger of electric shock. During

power-on, do not touch the cables, control terminals, radiator and the pore plate on the housing of the drive.

The drive must be properly earthed to reduce electrical accident.

Install the cover before switching on the drive, to reduce the danger of electric shock and explosion.

For drives that have been stored for longer than 2 years, increase its input voltage gradually before supplying full rated input voltage to it in order to avoid electric shock and explosion.

Perform the maintenance job after confirming that the charging

LED is off or the DC Bus voltage is below 36V.

Only trained professionals can change the components, it is prohibited to leave wires or metal parts inside the drive to avoid the risk of fire.

Parameter settings of the control board that has been changed must be revised, otherwise accidents may occur.

The bare portions of the power cables must be bound with insulation tapes.

When using optional parts, it is recommended to use those provided by Emerson Network Power, to secure safety.

Attention

Don’t carry the drive by its cover. Its cover cannot sustain the weight and may drop.

Please install the drive on a strong support, failing which the drive

may fall off.

Don’t install the drive in places where water pipes may leak onto it.

Don't allow screws, washers and other metal foreign matters to fall inside the drive, otherwise there is a danger of fire or damage;

Don't operate the drive if parts are not complete; there is a

danger of a fire or human injury;

Don't install the drive under direct sunshine; it may be damaged

by heat;

Don’t short circuit P1/PB and terminal (-) , there is a danger of fire

or the drive may be damaged.

Cable lugs must be connected to main terminals firmly.

Don’s apply supply voltage (AC 110V or higher) to the control

terminals except terminals TA, TB and TC.

1.3 Notes For Using The Drive

Pay attention to the following issues when using EV1000 Series drive:

1.3.1 About Motor And Load

Compared to working at mains frequency, there will be some increase in temperature, noise and vibration in the motor. The EV1000 Series are voltage source inverters. Its output voltage is in PWM wave. Being non-sinusoidal, there will be some harmonics.

Low Speed Rotation with Constant Torque When a standard motor is driven at low speed for a long time,

there will be insufficient cooling for a self-ventilated motor. Overheating can result in insulation damaged. Special variable frequency motor is recommended for constant torque operation at low speed.

Motor’s over-temperature protecting threshold

The drive can protect the motor from over-temperature. If the power rating of the drive is greater than the motor, be sure to adjust the protection parameters to ensure the motor is properly protected.

Operate above 50Hz

When running the motor above 50Hz, there will be increase in vibration and noise. The rate at which the torque is available from the motor is inversely proportionally to its increase in running speed. Ensure that the motor can still provide sufficient torque to the load.

Lubrication of mechanical devices

Over time, the lubricants in mechanical devices, such as gear box, geared motor, etc. when running at low speed, will deteriorate. Frequent maintenance is recommended.

Regenerative Energy

When lifting load, regenerative energy is produced, the drive will trip on overvoltage when it cannot absorb the regenerative energy of the load. Therefore, a proper braking unit is required.

Page 5

Chapter 1 Safety Information 3

EV1000 Series General Purpose Variable Speed Drive User Manual

Mechanical resonance point of load

The drive system may encounter mechanical resonance with the load when operating within certain band of output frequency. Skip frequencies have to be set to avoid it.

Frequent start and stop

The drive should be started and stopped via its control terminals. It is prohibited to start and stop the drive directly through contactors at the input side, which may damage the drive.

Insulation of Motors

Before using the drive, the insulation of the motors must be checked, especially, if it is used for the first time or if it has been stored for a long time. This is to reduce the risk of the drive from being damaged by the poor insulation of the motor winding. Wiring diagram is shown in Figure 1-1. Please use 500V insulation tester to measure the insulation resistance. It should not be less than 5MΩ.

1.3.2 About Variable Speed Drive

Varistors for Surge Protection or Cap acitors Used to Improve the Power Factor

Don't connect any varistor or capacitor to the output terminals of the drive, because the drive's output voltage waveform is pulse wave. Tripping or damage to components may occur as shown in Figure1-1.

U V

EV1000

Drive

Figure 1-1 Capacitors at output are prohibited

Circuit breakers connected to the output of the drive

If circuit breaker or contactor needs to be connected between the drive and the motor, be sure to operate these circuit breakers or contactor when the drive has no output to avoid damaging of the drive.

Using host communication function

When the parameters are modified frequently through host communication function, improper command will result in erasable memory damaged. If no need to save upon

power-off, please do not use 0x41 command. Please refer to Appendix 2.

Using outside rated voltage

The drive is not suitable to be used out of the specified range of operation voltage. If needed, please use suitable voltage regulation device.

Protection against lightning strike

There are transient surge suppressors inside the drive that protect it against lighting strike.

Derating due to Altitude

Derating must be considered when the drive is installed at high altitude, greater than 1000m. This is because the cooling effect of the drive is less effective in the thin air. Figure1-2 that shows the relationship between the altitude and rated current of the drive.

1.4 Disposing Unwanted Drive

When disposing the drive, pay attention to the following factors:

The capacitors may explode when they are burnt. Poisonous gas may be generated when the plastic parts like

front covers are burnt. Disposing method: Please dispose the drive as industrial

waste.

3.1 Installation

Please mount the drive vertically indoors, with good ventilative conditions.

When selecting mounting environment, the followings should be taken into account:

Ambient temperature should be within the range of -10°C ~40 °C. If the temperature is higher than 40 °C, the Variable Speed Drive should be derated and forced heat dissipation is required;

Humidity should be lower than 95%, non-condensing Mount in the location where vibration is less than 5.9m/ s

(0.6G) ; Mount in the location free of direct sunlight, dust, metal

powder, corrosive gas or combustible gas. If there are any special requirements for installation, please

shown in Figure 3-1 and Figure 3-2. When two Variable Speed Drives are mounted one on top

the other, an air flow diverting plate should be fixed in between as shown in Figure 3-2.

3.1.1 EMC Compliance Installation

In a traction system composed of the drive and a motor, if the drive, controllers and transducer are installed in one cabinet, the disturbance they generate should be depressed at the connection points, therefore, a noise filter and inrush reactor should be installed in the cabinet, so that EMC requirement is met inside it.

The drive is usually installed in a metal cabinet. The instruments outside the metal cabinet is shielded and may be disturbed lightly. The cables are the main EMI source, if you connect the cables according to the manual, the EMI can be suppressed effectively.

In system design phase, to reduce EMI, insulating the noise source and using noise snubber are best choice. But the cost is considerable. If there are a few sensitive devices on site, just install power line filter beside them is enough. Note that the drive and contactor are noise source, and the automatic devices, encoder and transducer are sensible to them.

Divide the system into several EMC areas, refer to Figure

3-4.

 Note

1. After installing EMI filter and AC reactor, the drive can satisfy IEC 61800-3 standard.

2. The input/output EMI filter should be installed close to the drive as possible.

3. Refer to Appendix 3 for the specifications of optional parts.

3.1.2 Noise Suppression

The noise generated by the drive may disturb the equipment nearby. The degree of disturbance is dependent on the drive system, immunity of the equipment, wire connections, installation clearance and earthing methods.

Table 3-1 Method of Noise Suppression

Noise emission paths Actions to reduce the noise If the external equipment shares the same AC supply with the drive, the drive’s noise may be transmitted along its input power supply cables, which may cause nuisance tripping to other external equipment.

Install noise filter at the input side of the drive, and use an isolation transformer or line filter to prevent the noise from disturbing the external equipment.

If the signal cables of measuring meters, radio equipment and sensors are installed in a cabinet together with the drive, these equipment cables will be easily disturbed.

1) The equipment and the signal cables should be as far away as possible from the drive. The signal cables should be shielded and the shielding layer should be grounded. The signal cables should be placed inside a metal tube and should be located as far away as possible from the input/output cables of the drive. If the signal cables must cross over the power cables, they should be placed at right angle to one another.

2) Install radio noise filter and linear noise filter (ferrite common-mode choke) at the input and output sides of the drive to suppress the emission noise of power lines.

3) Motor cables should be placed in a tube thicker than 2mm or buried in a cement conduit. Power cables should be placed inside a metal tube and be grounded by shielding layer (Motor cable should be a 4-core cable, where one core should be connected to the PE of the drive and another should be connected to the motor’s enclosure) .

If the signal cables are routed in parallel with the power cables or bundle these cables together, the induced electro-magnetic noise and induced ESD noise may disturb the signal cables.

Avoide this kind of routing. Other equipment sensibleto EMI should also be located as far away as possible from the drive. The signal cables should be placed inside a metal tube and should be placed as far away as possible from the input/output cables of the drive. The signal cables and power cables should be shielded cables. EMC interference will be further reduced if they could be placed inside metal tubes. The clearance between the metal tubes should be at least 20cm.

3.1.3 Using Surge Suppressor

The devices such as relay, contactor and electro-magnetic braking kit, which may generate great noises, should be installed with surge suppressors even if installed outside of the drive cabinet.

3.1.4 Leakage Current

Leakage current may flow through the drive’s input and output capacitors and the motor’s capacitor. The leakage current value is dependent on the distributed capacitance and carrier wave frequency. The leakage current includes ground leakage current and the leakage current between lines.

Ground leakage current

The ground leakage current not only flows into the drive system, but also into other equipment via earthing cables. It may cause leakage current circuit breaker and relays to be falsely activated. The higher the drive’s carrier wave frequency, the higher the leakage current, and also, the longer the motor cable, the greater is the leakage current.

Suppressing methods: Reduce the carrier wave frequency, but the motor noise may

be higher. Motor cables should be as short as possible; The drive and other equipment should use leakage current

circuit breaker designed for protecting the product against high-order harmonics/surge leakage current.

Leakage current between lines

The line leakage current flowing outside through the distributed capacitors of the drive may false trigger the thermal relay, especially for the drive of which power rating is less than 7.5kW. When the cable is longer than 50m, the ratio of leakage current to motor rated current may increase to a level that can cause the external thermal relay to trigger unexpectedly.

Suppression methods: Reduce the carrier wave frequency, but the motor audible

noise is higher. Install reactor at the output side of the drive.

In order to protect the motor reliably, it is recommended to use a temperature sensor to detect the motor’s temperature, and use the drive’s over-load protection device (electronic thermal relay) instead of an external thermal relay.

3.1.5 Applications Of Power Filter

Power source filter should be used in the equipment that may generate strong EMI or the equipment that is sensitive to EMI. The power source filter should be a low pass filter through which only 50Hz current can flow and high frequency current is rejected.

The power line filter ensures the equipment can satisfy the conducting emission and conducting sensitivity in EMC standard. It can also suppress the radiated emission of the equipment.

It can prevent the EMI generated by the equipment from entering power cable, and also prevent the EMI generated by power cable from entering equipment.

Common mistakes in using power line filter

1. Too long power cable The filter inside the cabinet should be located near to the

input power source. The length of the power cables should be as short as possible.

2. The input and output cables of the AC supply filter are too close

The distance between input and output cables of the filter should be as far apart as possible, otherwise the high frequency noise may be coupled between the cables and bypass the filter. Thus, the filtering effect becomes ineffective.

3. Bad earthing of filter The filter’s enclosure must be connected properly to the

metal casing of the drive. In order to be earthed well, a special earthing terminal on the filter’s enclosure should be used. If you use one cable to connect the filter to the case, the earthing is useless due to high frequency interference. When the frequency is high, so too is the impedance of cable, hence there is little bypass effect.

The filter should be mounted in the enclosure of equipment. Ensure to clear away the insulation paint between the filter case and the enclosure for good earth contact.

3.1.6 AC Line Reactor Applications

Input AC Line Reactor

A line reactor should be used if the distortion of power network is severe or the input current harmonic level is high even after a DC reactor has been connected to the drive. It can also be used to improve the AC input power factor of the drive.

Output AC Line Reactor

When the cables from the drive to motor are longer than 80m, multi-strand cables and an AC line reactor should be

Page 14

12 Chapter 3 Installation and Wiring

EV1000 Series General Purpose Variable Speed Drive User Manual

used to suppress the high frequency harmonics. Thus, the motor insulation is protected. At the same time, leakage current and unexpected trigger are reduced.

3.2 Wiring

Danger

Wiring can only be done after the Variable Speed Drive’s AC

power is disconnected, all the LEDs on the operation panel are off and after waiting for at least 5 minutes. Then, you can remove the panel.

Wiring job can only be done after confirming the Charge indicator inside the drive has extinguished and the voltage between main circuit power terminals + and - is below DC36V.

Wire connections can only be done by trained and authorized personnel.

Check the wiring carefully before connecting emergency stopping or safety circuits.

For the sake of safety, the drive and motor must be earthed because there is leakage current inside the drive.

Check the Variable Speed Drive’s voltage level before supplying

power to it, otherwise human injuring or equipment damage may happen.

Attention

Check whether the Variable Speed Drive’s rated input voltage is

in compliant with the AC supply voltage before using.

Dielectric strength test of the drive has been done in factory and

the user needs not do it again.

Refer to chapter 2 on how to connect braking resistor or braking

kit.

It is prohibited to connect the AC supply cables to the drive’s

terminals U, V and W.

Grounding cables should be copper cables with cross-sectional

area bigger than 3.5mm

, and the grounding resistance should be

less than 10Ω.

The drive should be connected to the AC supply via a circuit breaker or fuse to provide input over-current protection and also for maintenance purpose.

The control circuits are isolated from the power circuits in the drive by basic insulation (single insulation) only. If the control cables are to connect to external control circuit exposing to human contact, an extra insulating layer, rated for use at the AC supply voltage of the load, must be applied.

If the control circuits are to connect to other circuits classified as Safety Extra Low Voltage (SELV) , e.g. connecting the RS485 port of the drive to a personal computer through an adapter, an additional isolating barrier must be included in order to maintain the SELV classification.

Attention

The control terminals of the drive is of ELV (Extra Low Voltage)

circuit. Do not touch them once energized;

If the external device has touchable terminals of SELV (Safety Extra Low Voltage) circuit. Remember to connect isolating protections in between. Otherwise, the SELV circuit will be degraded to ELV circuit;

When connecting the drive with PC, do choose RS485/232 adapters with isolating protections that measure up to safety

requirements.

3.2.1 Overview

You should finish the power circuit and control circuit wiring. First, remove the screws on the keypad, open the front door

and then you will see the power terminals and control terminals.

For different models of the drive, the power terminals layout is different, which will be described in details later.

Beneath the keypad display unit, there are control terminal

strip: CN5, CN6 and jumper CN16, CN17, CN10.

CN5 is for relay output; CN6 is for analog, digital I/O and communication interfaces.

CN16, CN17 and CN10 are jumpers, through which the output of voltage or current signal is set. The terminals will be described in details later.

1. When using analog input, you should install capacitor-filter or common-mode inductor between VCI and GND, or between CCI and GND.

2. Analog I/O signals are sensible to interference, ensure to use shielded cable and ground it properly. The cable length should be as short as possible.

3) Serial Communication Port Connection The drive can be connected to the host with RS485 port

directly. Figure 3-12 shows the connection of the drive with the host

with RS232 port. Figure 3-13 shows the connection of the drive to PROFIBUS

system via TDS-PA01 PROFIBUS adapter. Using above wiring method, you can build a “single-master

single slave” system or a “single-master multi-slaves” system. The drives in the network can be monitored, and be controlled remotely and automatically in real time by using a PC or PLC controller. Thus more complicated operation control can be realized.

Precautions for communication port connection: z The PE terminal of each drive shoul d be earthed at a

nearby grounding point;

z The GND terminal of each driv e should be connected

together;

z RS485 communication uses shielded cables, which is

earthed at one side. The earth wire of the shielded cable is connected to RS485 communication module (PE) .

If the above standard wiring methods cannot meet the requirements, you can take the actions below:

z Use isolated RS485 communication module; z If the noise is transmitted through the GND line to the

drive or other devices, which results in malfunction of them, you may disconnect the GND lines.

4) Multi-function Input Terminal and FWD, REV Wiring The multi-function input terminals use full-bridge rectifying

 Note

1. Don’t short terminals P24 and COM, otherwise the control board may be damaged.

2. Use multi-core shielded cable or multi-strand cable (above 1mm) to connect the control terminals.

3. When using a shielded cable, the shielded layer’s end that is nearer to the drive should be connected to PE.

4. The control cables should be as far away (at least 20cm) as possible from the main circuits and high voltage cables (including power supply cables, motor cables, relay cables and cables of contactor) . The cables should be vertical to each other to reduce the disturbance to minimum.

3.2.4 Onsite Wiring Requirements

To avoid mutual EMI disturbance, the control cables, power cable and motor cable should be installed as apart as

possible, especially when they are routed in parallel for rather long distance. If the signal cable must cross the power cable or motor cable, keep them at right angle to each other.

Figure 3-23 Cable routing schematic diagram

If the section area of the motor cable is too big, the motor should derate. Refer the drive’s cable specs in Table 3-2. Since the larger the section area of cables, the greater their capacitance to the ground, therefore, the output current should derate 5% with increasing every category of cable section area.

Shielded/armored cable: high-frequency low-impedance shielded cable should be used, such as woven copper mesh, aluminum mesh or metal mesh.

The control cable should be shielded, and the clamps at both ends of the metal mesh should be connected to the earth terminal of the drive enclosure.

Use conductive plate and dentate pad to clear away the paint between the screws and metal casing, to ensure good conductivity.

Besides, pay attention to the following points: In order to reduce the earthing resistance, flat cable should

be used because the high frequency impedance of flat cable is smaller than that of round cable with the same CSA.

For 4-core motor cable, the end of one cable should be connected to the PE of the drive, and the other end should be connected to the motor’s enclosure. If the motor and the drive each has its own earthing pole, then the earthing effect is better.

If the earthing poles of different equipment in one system are connected together, then the leakage current will be a noise source that may disturb the whole system. Therefore, the drive’s earthing pole should be separated with the earthing pole of other equipment such as audio equipment, sensors and PC, etc.

In order to reduce the high frequency impedance, the bolts used for fixing the equipment can be used as the high frequency terminal. The paints on the bolt should be cleaned.

The earthing cable should be as short as possible, that is, the earthing point should be as close as possible to the drive.

Earthing cables should be located as far away as possible from the I/O cables of the equipment that is sensitive to noise, and lead should also be as short as possible.

Chapter 4 Operation Procedures

4.1 Term Definition

In the follow-up sections, you may encounter the terms describing the control, running and status of drive many times. Please read this section carefully. It will help you to understand and use the functions to be discussed correctly.

4.1.1 Drive Control Modes

It defines the methods by which drive receives operating commands like START, STOP, FWD, REV, JOG and others.

Keypad control: The drive is controlled by RUN, STOP and JOG keys on the LED keypad;

Terminal control: The drive is controlled by terminals FWD, REV and COM (two-wire mode) , Xi (3-wire mode) ;.

Host control: The operations such as START and STOP is controlled by host PC.

The control modes can be selected by parameter F0.03, multi-function input terminals (function No. 27, 28 and 29 of F7.00) .

4.1.2 Frequency Setting Methods

There are 7 methods to set frequency, they are: ▲and ▼ key on the keypad; Terminal UP/DN; Serial communication port; Analog VCI; Analog CCI; Terminal (PULSE) ; Potentiometer on the keypad. How to select the frequency setting methods, please refer to

F0.00.

How to set Frequency

The output frequency is decided after calculating the values from one or more of the 7 frequency setting channels, which involves the concept of main and auxiliary reference frequency.

Main reference frequency: set by F0.00, multi-speed (MS) or close loop control.

The main reference frequency is decided by the priority of running mode. The priority level is Jog>close loop>PLC>MS (multi-speed) >common running, e.g. if the drive is running in MS mode, the primary reference frequency is MS frequency.

Auxiliary reference frequency: set by F9.01~F9.04. Preset frequency: the sum of main and auxiliary frequency

multiply a factor, which is set in F9.05 and F9.06. Please refer to F9.05, F9.06 and Figure 5-58 in chapter 5.

4.1.3 Drive Operating Status

There are 3 operating status: stop, operating and motor parameter tuning.

Stop: After the drive is switched on and initialized, if no operating command is received or the stop command is executed, then the drive enters stop status.

Operating: after receiving run command, the drive begins to

operate.

Motor parameter tuning: If FH.09 is set at 1 or 2, after giving RUN command, the drive will enter motor parameter tuning status, and then it will stay in stop status.

4.1.4 Operating Mode

The drive has 5 kinds of operating modes which can be arranged in the sequence of “Jog>Close loop operation>PLC>MS>Simple operation” according to the priority.

Jog: When the drive is in stop status, it will operate according to

Jog frequency after it receives the Jog operation command (See F3.13~F3.16) .

Close-loop operation: If the close-loop operating function is enabled (F5.00=1) ,

the drive will select the close-loop operation mode, meaning that it will perform PI regulation according to the reference and feedback values (See explanations of Parameter F5) . Close-loop operating function can be disabled by multi-function terminal (function No. 20) , and the drive will then select other operating mode of lower priority level.

PLC running: PLC function is enabled if the one’s place of F4.00 setting is

a non-zero value. The drive will run according to the preset mode, see F4 function group. It can be disabled by multi-function terminal (function No.21) .

MS Running:

Select multi-frequency 1~7 (F3.23~F3.29) by the combination of multi-function terminal (function No. 1, 2, 3) , which is not zero.

Simple Running: open-loop operation. The above 5 operating modes determine 5 frequency setting

sources. Except Jog, the other four frequency settings can be adjusted or combined with auxiliary frequency. The frequency of PLC, MS and simple running can also be adjusted by traverse.

4.2.4 Parameter Setting Method

Parameter System

The EV1000 series drive has 17 function group: F0~F9, FA, FF, FH, FL, Fn, FP and FU. Each function group includes many parameter, which is presented as function group number + parameter number, e.g. F5.08.

Menu Structure and Parameter

When setting parameter through LED keypad display unit, function group is listed in menu level 1, parameter in menu level 2, and settings of parameters in menu level 3. See Appendix 1.

Examples of Parameter Setting

The setting of parameter is presented in decimal (DEC) and hexadecimal (HEX) format. If it is set in hexadecimal format, each digit of the setting is independent to one another, which can be 0~F. The re are at most 4 digits, they are: one’s place, ten’s place, hundred’s place and thousand’s place. You may select certain digit by pressing key, and use ▲ and ▼ key to increase or decrease values.

Example 1: To change the frequency from 50Hz to 40Hz (F0.12: 50.00 40.00)

1. Press PRG key to enter programming state, the LED displays F0.

2. Press FUNC/DATA key, “F0.00” is displayed. Press ▲ key until “F0.12” is displayed.

3. Press FUNC/DATA key, you will see 50.00.

4. Press  key, to move the cursor to the digit “5”.

5. Press ▼ key once, to change the digit to “4”.

6. Press FUNC/DATA key to save the modification and you will see the next parameter F0.13.

7. Press PRG key to exit the programming state.

Example 2: Settings of HEX format. Take F8.01 (Display parameter during running) for example. Suppose you hope to display: reference setting, actual speed, set

speed, actual line speed and set line speed. Since each digit is mutually independent, you may set them separately. First you should decide the binary value, and then

convert it into hex format. The conversion of binary value to HEX value is shown in Table 5-11.

1. Set one’s place. Refer to the figure below. Reference Frequency is decided by the BIT2 of the one’s place of F8.01. If BIT2=1, it means the

parameter will be displayed. For those parameters you don’t want to display, you may set the corresponding bit at Zero. Therefore, it turns out to be “0100”, after converting to HEX value, it is 4. So , you should set the one’s place at 4.

2. Set Ten’s place Similarly, set the corresponding bit at “1” for those parameters you want to display, you will get “1111”, i.e. “F”.

3. Set Hundred’s and Thousand’s place Since no parameters related to hundred’s and thousand’s place are required to display, so they are set at zero. From the above, F8.01 is set at 00F4.

Close-loop reference selectors can be preset close-loop reference I or determined by parameter F5.01; and the feedback is determined by F5.02. When the setting method is determined by F5.01, the terminals can be selected via close-loop input. See F7.00~F7.07 and F5.20~F5.26 for details

 Note

When the PLC operating direction is determined by operating commands, the motor’s operating direction can be changed by external command. For example, Running forward can be ordered by terminal FWD-COM. The direction is decided by running command and if it cannot be determined, the drive will runs in the direction of last operating stage.

5.6 Close-loop Control (F5)

Usually, the close loop control can be divided into two types:

analog close loop and pulse close loop according to feedback. Figure 5-28 and Figure 5-29 are analog and pulse close loop control wiring diagram.

Figure 5-29 PG Speed Close Loop Control System

Analog feedback control system: An analog feedback control system can be formed by a

pressure transducer as the feedback sensor of the internal PI.

As shown in, pressure reference (voltage signal) is input via terminal VCI, while the feedback pressure value is input to terminal CCI in the form of 0~20mA current signal. The reference signal and feedback signal are detected by the analog channel. The start and stop of the drive can be controlled by terminal FWD.

The above system can also use a TG (speed measuring generator) as speed close speed-loop control

PG speed close-loop control: A speed close-loop control system can be formed by

external control terminals X

and X5, and pulse generator

(PG) . As shown in Figure 5-29, close speed-loop input can come

from a potentiometer in the form of voltage signal via terminal VCI, while the feedback value of the close loop is input by PG in pulse mode via terminal X4 and X5. The start and stop of the drive can be controlled by terminal FWD.

In Figure 5-29, A and B are PG’s dual phase quadrature output; P24 is connected to the power source of PG; Speed reference is the voltage signal of 0~10V. The voltage

signal corresponds to synchronous speed n

which, in turn, corresponds to 0~Max frequency (F0.05) . P is the number of poles of motor (FH.00) .

n0=120 × f

max

Refer to function No. 47~48 of F7.00~F7.04 for the functions of input terminals X4, X5.

 Note

1. The reference can also be input via keypad or serial port;

2. Dual-phase input can improve the speed measurement accuracy, while single phase input wiring is simple;

3. Dual-phase pulse can only be input in quadrature mode;

4. If PG is supplied from terminal P24, then the max load current of optical PG must be less than 100mA.

There are two features of internal PI: The relationship between reference and feedback can be

defined by F5.08~F5.11. For example: In Figure 5-2828, if the reference is 0~10V

analog signal, the expected controlled value is 0~1MP, and the pressure signal is 4~20mA, then the relationship between reference and feedback is shown in Figure 5-31.

The reference value is based on 10V (i.e. 10V means 100% input) ; and the feedback value is based on 20mA (20mA corresponds to 100% output) .

Close-loop characteristic is selected through F5.16 to satisfy different applications.

In order to meet the control requirements, the motor’s speed should be increased with reference speed. This kind of control characteristic is called positive response. If the motor speed is required to be decreased when the reference value is increased, this control characteristic is called negative response.

See Figure 5-32. F5.16 defines the two characteristics.

After the system type is determined, the following procedures can be used to determine the close loop parameters:

z Determine the close-loop reference and feedback

channel (F5.01 and F5.02) ;

z Define the relationship between close-loop reference

and feedback value (F5.08~F5.11) ;

z Determine the speed reference of speed close-loop

control and the number of revolutions of PG (F5.06~F5.07) ;

z Determine the close-loop regulation characteristic, that

is, if the motor speed decreases while the input reference increases, then the close-loop control characteristic should be set to negative (F5.16=1) ;

z Set integral regulation and close-loop frequency

(F5.17~F5.19) ;

z Adjust close-loop filter time, sampling cycle, bias limit

Range: 0.01~50.00s【0.50s】

F5.04 Feedback filter

Range: 0.01~50.00s【0.50s】

Both the input signal and feedback signal have some noise signals. These signals can be filtered by setting the time constant of filter (settings of F5.03 and F5.04) . The bigger the time constant, the better the immunity capability, but the response becomes slow. The smaller the time constant, the faster the response, but the immunity capability becomes weak.

The bigger the proportional gain Kp, the faster the response, but oscillation may occur easily if Kp is too big.

If only proportional gain KP is used in regulation, the error cannot be eliminated completely. Therefore, it is preferred to use the integral gain Ki to form a PI control system. The bigger the Ki, the faster the response, but oscillation may occur if Ki is too big.

F5.04 refers to the sampling cycle of feedback value. The PI regulator calculate once in each sampling cycle. The bigger the sampling cycle the slower the response.

F5.15 Error limit

5.7 Traverse Parameters (F6)

Traverse function applies to textile and chemical fiber industry, or others that requires lateral movement or rolling. The typical application is shown in Figure 5-36.

The drive works as follows: The drive accelerates to preset traverse frequency F6.02 and stay at it for a period of time (F6.03) . Next, It will arrive at central

frequency within Acc time, and then it will operate according to traverse amplitude (F6.04) , skip frequency (F6.05) , traverse cycle (F6.06) and rise time (F6.07) one cycle after another until the Stop command is received. It will then decelerate to stop within Dec time.

ON OFF Acc time 3/Dec time 3 ON ON Acc time 4/Dec time 4

By combination of the ON/OFF state of Terminal 1 and 2, you can get 4 groups of Acc/Dec time.

6~7: External fault signal (normally-open/close input)

If the setting is 6~7, fault signal of external equipment can be input via the terminal, which is convenient for the drive to monitor the fault of external equipment. Once the drive receives the fault signal, it will display “E015”. The fault signal has two input modes, i.e. normally-open and normally-close.

COM

EV1000

Figure 5-40 Normally-open/close input

In Figure 5-40, X4 is normally open input and X5 normally close input. KM is external fault relay.

8: Reset

If any of F7.00~F7.04 is set at 8, the drive can be reset via the terminal when the drive has a fault. The function of this terminal is the same with the RESET key on the keypad.

9~10: External jog command (JOGF/JOGR)

If any of F7.00~F7.04 is set at 9~10, the terminal can enable the jog operation. JOGF is terminal for forward jog operation command and JOGR is terminal for reverse jog operation command. Jog frequency, jog interval and jog Acc/Dec time are defined in F3.13~F3.16.

11: Coast to stop

This function is the same with F2.08, however, it is realized by terminal and convenient for remote control.

12~13: Frequency increase (UP) /decrease (DN)

If the setting is 12~13, the terminal can be used to increase or decrease frequency instead of  and  keys on the panel for remote control. This terminal is valid when F0.00=1 or F9.01=2. Increasing or decreasing rate is determined by F7.09.

14: Pause command for simple PLC

If the setting is 14, the terminal is used to pause the PLC operation and the drive operates at zero frequency when the terminal is enabled, but the running time is not counted. If the terminal is disabled, the drive will start at start frequency

Page 41

Chapter 5 Parameters 39

EV1000 Series General Purpose Variable Speed Drive User Manual

and continue the PLC operation. Refer to F4.00~F4.14 for

the use of this terminal.

15: Acc/Dec prohibit

The motor is immune to any external command except Stop

command and maintain the present speed.

 Note

This function is disabled during normal decelerating to stop.

16: 3-wire operation control.

Refer to F7.08 .

17~18: External interrupt signal normally-open input

When the drive receives an interrupt signal during running, it

will stop outputs and run at zero frequency. Once the signal

removed, the drive will resume previous running at start

frequency.

As Figure 5-40 shows, there are X4, normally open contacts

and X5, normally closed contact.

 Note

Different from function 6~7, the external interrupt signal will not

cause alarm, and the drive will resume previous running once the

signal removed.

19: DC Braking (DB)

If the setting is 19, the terminal can be used to perform DC

injection braking to the motor that is running for emergency

stop and accurate location. Initial braking frequency, braking

delay time and braking current are defined by F2.09~F2.11.

Braking time is decided by the bigger value between F2.12

and the period that the terminal is effective.

20: Disable close-loop

If the setting is 20, the terminal can be used to realize the flexible switching between close-loop operation and low level operating mode.

 Note

The switching between operation modes is possible when the

drive is in close-loop mode (F5.00=1) .

When the drive is switched to low level operating mode, its

start/stop, operating direction, ACC/Dec time are shifted to

the corresponding operating modes accordingly.

21: Disable PLC

If the setting is 21, the terminal is used to realize the flexible

switching between PLC operation and low level operating

mode.

 Note

The switching between operation modes is possible only when the

drive is in PLC operation (the one’s place of F4.00 is not 0) .

When the drive is switched to low level operating mode, its

start/stop, operating direction, ACC/Dec time are shifted to

the corresponding operating modes accordingly.

22~24: Reference frequency setting method

Through the combination of the ON/OFF state of X1, X2 and

X3, you can select different frequency setting method, which will come into effect regardless of F0.00.

Table 5-6 Frequency Setting Mode Selection

X3 X2 X1 Mode OFF OFF OFF None OFF OFF ON Digital setting1 OFF ON OFF Digital setting 2 OFF ON ON Digital setting 3

25: Frequency reference is input via terminal CCI

If the setting is 25, the frequency reference will be input via terminal CCI forcibly. The frequency input will be changed to the previous one if this terminal function is disabled.

26: Not used 27: Terminal control mode is enabled

When this terminal function is enabled, the operating command is input through this terminal forcibly. The drive will be controlled in the previous mode if FWD/REV terminal function is disabled.

28~29: Control mode selection X1~X2

Table 5-7 Control Mode Selection

The setting of F9.15 (length) will be cleared to zero.

40: Clear the setting of auxiliary reference frequency

This function is valid for auxiliary reference frequency (F9.01=1, 2 and 3) to clear it to zero, so that the reference frequency is determined solely by main reference.

41: Reset PLC state

When the drive stops in PLC mode, the memorized PLC operating information (operating stage, operating time, operating frequency, etc.) will be cleared.

42: clear the counter to zero

This function is to clear the counter to zero and is used in conjunction with function 43.

43: Input signal to trigger the counter

When the setting is 43, this terminal is used to input counting pulse signal to the internal counter of the drive. The max. pulse frequency is 200Hz. The present counting value can be saved at power off. See F7.33 and F7.34 for details.

44: input the signal of length

This function is only effective to multi-function input terminals X4 and X5. The terminal is used in fixed-length control. Length is calculated by input pulses. See F9.14~F9.19 for details.

45: pulse frequency input

This function is effective only to multi-function input terminals X4 and X5. The terminal is used to input pulse signal that is used as frequency reference. Refer tp F1 parameters for the relationship between input pulse frequency and the reference frequency.

46: Single-phase speed measuring input

This function is effective only to multi-function input terminals X4 and X5. See section 3.2.3 for input characteristics. The speed control accuracy is ±0.1%. Single-phase speed feedback control can be realized by using this terminal and PG.

47: Speed measuring input SM1 48: Speed measuring input SM2

This function is effective only to multi-function input terminals X4 and X5. See section 3.2.3 for input characteristics. The

speed control accuracy is ±0.1%. 2-phase speed feedback control can be realized by using this terminal and PG.

The above two parameters are to set zero frequency hysteresis control.

Take analog CCI for example, see Figure5-66: Startup process: When the Run command is given out, only after CCI current

arrives at I

and the corresponding frequency reaches fb,

does the drive start and accelerate to the preset frequency. Stop: During operation, if CCI current reduces to Ib, the drive will

not stop until it reaches I

and the corresponding frequency becomes fa, where fa is the threshold of zero frequency defined by F9.12. The difference between fb and fa is zero frequency hysteresis, defined by F9.13.

This function can realize dormancy to save energy. In addition, the frequent start and stop at threshold frequency can be avoided.

The above parameters are used for length control, i.e. the drive will stop when arriving certain length.

The counting pulse is input from X4 or X5 which is defined

as function No. 44, refer to F7.03~F7.04. The length is calculated based on F9.19 and F9.18.

Calculated length＝number of counting pulse÷ number of pulse per revolution × shaft circumference After correcting the calculated length by F9.16 and F9.17, the actual length is obtained.

Actual length＝calculated length × F9.16÷F9.17 When the actual length (F9.15) ≥ preset length (F9.14) , the

drive will stop automatically. You must clear the actual length record or modify the setting of it to a value smaller than F9.14, or the drive cannot be started.

 Note

The actual length can be cleared by multi-function input terminal, i.e. to set the corresponding parameter of Xi at 39. The actual length and pulse number can be calculated only after this terminal is disconnected.

Actual length (F9.15) will be saved after power off automatically. Function of stop at fixed length is disabled if F9.14 is set to 0, but

the calculated length is still effective.

Application of stop at fixed length:

Figure 5-67 Application of Stop at Fixed Length

In Figure 5-67, the drive drives the motor, and the motor, in turn, drives the spindle through the conveyer. The shaft that contact with the spindle can measure the line speed of it which will be transmit to the drive by the sensor in the form of pulse. The drive will calculate the length based on the number of pulses it received. When the actual length ≥ preset length, the drive will give Stop command automatically to stop the spinning. The operator can remove the spindle and close the “Clear Length” terminal (set any of F7.00~7.04 at 39) . The drive is then ready for the next spindle process.

F9.20 is to select whether to enable low voltage compensation in case of voltage drop or undervoltage by reducing output frequency to get energy feedbacked from the load, so that the drive will not trip.

F9.20=0, disabled F9.20=1, enabled If the setting of F9.21 is set too big, the feedback energy of

motor will be more than expected and may cause over-voltage protection; if the setting of F9.21 is set to small, the feedback energy of motor is not enough, hence trip might occur. It is recommended to set F9.21 according to load and its inertia.

This parameter sets the communication mode. Virtual terminal is set by host command to simulate the

actual terminal. Each bit of the command represents the state of corresponding terminal. Please refer to Appendix 2. When the virtual terminal, which function the same as the actual one, is effective, the actual terminal is disabled.

The setting of the thousand’s place does not affect the communication. When MODEM mode is selected, every time the drive is powered on, the MODEM will be initialized through the RS485 port, so that it can response

automatically after receiving 3 ring signals for remote control. Remember that a RS485-RS232 adapter is needed.

FF.01 Local address

Range:0~247【5】

In serial communication, FF.01 is used to identify the drive’s address.

Note: “0” is the broadcast address. When the address is set to broadcast address, the drive can receive and execute the command sent by control PC, but will not answer it.

FF.02 Communicate timeout detect

Range: 0~1000.0s【0.0s

When the communication signal is lost for a period longer than the setting of this parameter, the drive deems that communication fault occurs.

When it is set at 0, the drive will not detect the signals at the serial port, i.e., this function is invalid.

FF.03 Response delay

Range: 0~1000ms【5ms】

Response delay refers to the time from the drive receiving and executing the command of the host to returning reply frame to the host. For RTU mode, the actual response delay should be no less than 3.5 bytes’ transmitting time.

~FH.07 to the values calculated according to the above formula.

If the drive performs auto-tuning of motor’s parameters, then the settings of FH.03~FH.07 after the auto-tuning process will be updated.

After motor power (setting of FH.01) is changed, the drive will set FH.02~FH.07 to corresponding parameters.

FH.08 Rated slip frequency

Range: 0.00~20.00Hz【0.00Hz】

Motor’s rated slip frequency can be calculated by the motor’s rated speed (on the nameplate) :

Rated slip frequency = motor’s rated frequency (i.e. basic operating frequency F0.06) × (motor’s synchronous speed-motor’s rated speed) ÷motor’s synchronous speed.

Where: motor’s synchronous speed = motor’s rated frequency × 120÷number of motor’s poles (FH.00)

After setting the slip frequency, the slip compensation will be enabled by F3.07~F3.09.

FH.09 Auto tuning

Range: 0~2【0】

FH09 can be used to measure and write-in the motor’s parameters automatically.

0: Auto-tuning is disabled 1: Stationary auto-tuning (Start auto-tuning to a standstill

motor) Before starting auto-tuning, values on the motor’s nameplate

must be input correctly (FH.00~FH.02) . When starting auto-tuning to a standstill motor, the stator’s

resistance (%R1) , rotor’s resistance (%R2) and the leakage inductance (%X1) will be measured and the measured values will be written into FH.04, FH.05 and FH.06 automatically.

FH.09=2: rotating auto-tuning When starting a rotating auto-tuning, at first, the motor is in

standstill status, and the stator’s resistance (%R1) , rotor’s resistance (%R2) and the leakage inductance (%X1) will be measured, and then the motor begins to rotate, mutual inductance (%XM) , I0 will be measured and written into FH.04, FH.05, FH.06, FH.07 and FH.03 automatically.

After auto-tuning, FH.09 will be set to 0 automatically.

Auto-tuning procedures:

1) Set the “F0.06 basic operating frequency” and “F0.07 Max output voltage” correctly according to the motor’s feature;

2) Set the FH.00, FH.01 and FH.02 correctly;

3) If FH.09 is set to 2, Acc time (F0.10) and Dec time (F0.11) should be set correctly and remove the load from the motor and check the safety;

4) Set FH.09 to 1 or 2, press FUNC/DATA, and then press RUN to start auto-tuning;

5) When the operating LED turns off, that means the auto-tuning is over.

 Note

When setting FH.09 to 2, you may increase Acc/Dec time if over-current or over-voltage fault occurs in the auto-tuning process;

When setting FH.09 to 2, the motor’s load must be removed before starting rotating auto-tuning;

The motor must be in standstill status before starting the auto-tuning, otherwise the auto-tuning cannot be executed normally;

If it is inconvenient to start auto-tuning (e.g. the motor cannot break away from the load) , or you don’t require much on motor’s control performance, you can use stationary auto-tuning or even disable the function. You may input the values on the motor’s nameplate correctly (FH.00~FH.02) .

If the auto-tuning function is unavailable and there is motor’s parameters on the nameplate, you should input the values correctly (FH.00~FH.02) , and then input the calculated values (FH.03~FH.07) . Please set the parameters correctly.

If auto-tuning is not successful, the drive alarms and displays fault E024.

5.14 Protection (FL)

FL.00 Motor overload protection mode

Range: 0, 1, 2【1】

0: disabled The overload protection is disabled. Be careful to use this

function because the drive will not protect the motor in case of overload;

1:Common motor (with low speed compensation) Since cooling conditions of common motor deteriorates at

low speed, the motor’s thermal protection threshold should also be adjusted. The “Low Speed” here refers to the operating frequency lower than 30Hz.

2: Variable frequency motor (without low speed compensation)

The cooling effect of variable frequency motor is not affected by the motor’s speed, so low speed compensation is not necessary.

FL.01 Motor overload protection factor

Range: 20.0~110.0%【100.0%】

Model Range Default

380V 120.0%~150.0% 140.0% 220V 110.0%~130.0% 120.0%

When the drive is decelerating, the motor’s decreasing rate may be lower than that of the drive’s output frequency due to the inertia of load. At this time, the motor will feed the energy back to the drive, resulting in voltage rise on the drive's DC bus, which will cause overvoltage trip.

Function of FL.02: during the deceleration, the drive detects the bus voltage and compares it with the stall over voltage point defined by FL.03. If the bus voltage exceeds FL.03, the drive will stop reducing its output frequency. When the detected bus voltage is lower than the point, the deceleration will continue. Please refer to in Figure 5-71.

Auto current limiting function is used to limit the load current under the preset current in real time to avoid trip due to over-current. This function is especially useful for the applications of larger load inertia or sharp change of load.

FL.07 defines the threshold for current limiting. Its setting is a percentage of drive’s rated current Ie.

FL.08 defines the decreasing rate of output frequency when the drive is in auto current limiting status.

If FL.08 is set too small, overload fault may occur. If FL.08 is set too big, the drive may be in energy generation status for long time that may result in overvoltage protection.

The action mode of auto current limiting function is decided by FL.09.

FL.09＝0: disabled; FL.09＝1: auto current limiting is effective during

acceleration or deceleration but ineffective at constant speed, no silencing function;

FL.09＝2: effective all the time, no silencing function; FL.09＝3: auto current limiting is effective during

acceleration or deceleration but ineffective at constant speed, with silencing function;

FL.09＝4: effective all the time, with silencing function. Because the output frequency might change during current

limiting, the function should be used for applications that require constant speed and stable frequency output.

7.2 Periodic Maintenance

You should check the drive every 3 months or 6 months according to the actual environment.  Note

1. Only trained personnel can dismantle the drives for repairing or device replacement;

2. Don't leave metal parts like screws or pads in the drive, otherwise the equipment may be damaged.

General Inspection:

1. Whether screws of control terminals are loose. If so, tighten them with a screwdriver;

2. Whether the main circuit terminals are properly connected; whether the mains cables are over heated;

3. Whether the power cables and control cables are damaged, check especially for any wear on the cable insulation

4. Whether the insulating tapes around the cable lugs are stripped;

5. Clean the dust on PCBs and air ducts with a vacuum cleaner;

6. For drives that have been stored for a long time, it must be powered on every 2 years. When supplying AC power to the

drive, use a voltage regulator to raise the input voltage to rated input voltage gradually. The drive should be powered for 5 hours without driving a motor load.

7. Before performing insulation tests, all main circuit input/output terminals should be short-circuited with conductors. Then proceed insulation test to the ground. Insulation test of single main circuit terminal to ground is prohibited, The drive can be damaged by such a test. Please use a 500V Mega-Ohm-Meter.

8. If performing insulation test to the motor, be sure to disconnect the cables between the drive and it. Otherwise, the drive might be damaged.

Chapter 7 Maintenance 59

EV1000 Series General Purpose Variable Speed Drive User Manual

 Note

Dielectric test of the drive has already been done in the factory. It is not necessary for the user to do dielectric test again in order to avoid potential damage of its internal components.

7.3 Replacing Easily-worn Parts

The easily-worn parts of the drive are cooling fan and electrolytic capacitor, whose life has close relation with the environment and maintenance. Refer to the table below.

Part Life

Fan 30~40 thousand hours

Electrolytic capacitor 40~50 thousand hours

Relay TA/TB/TC About 100,000 times

You can decide the time when the components should be replaced according to their service time.

1. Cooling fan Possible cause of damages: wear of the bearing, aging of

the fan vanes. Criteria: After the drive is switched off, check if abnormal conditions

such as crack exists on fan vanes and other parts. When the drive is switched on, check if drive running is normal, and check if there is any abnormal vibration.

2. Electrolytic capacitors Possible cause of damages: high ambient temperature,

aging of electrolyte and large pulse current induced by rapid changing loads.

Criteria: Check if frequent over-current or over-voltage failures occur during drive start-up with load. Check if there is any leakage of liquids (electrolytes) . Check if the safety valve protrudes. Measure static capacitance and insulation resistance.

3．Relay TA/TB/TC Possible cause of damages: erosion, frequent operation. Criteria: ON/OFF malfunction.

7.4 Storing Drives

The following points must be followed for the temporary and long-term storage of drive:

1. Store in locations free of high temperature, humidity, dust, metal powder, and with good ventilation.

2. Long-term storage will cause the deterioration of electrolytic capacitors. Therefore, the drive must be switched on for a test within 2 years, for at least 5 hours. The input voltage must be applied gradually with a voltage regulator to the rated value.

7.5 Warranty

ENP will offer warranty service in the case of the following situations:

1. The warranty clause is confined only to the drive;

2. ENP will take the responsibility of 18 months defects liability period for any faults or damages under the normal operation conditions as of manufacture date. After 18 months, maintenance will be charged;

3. Even within 18 months, maintenance would be charged under the following conditions:

① Damages incurred to the drive due to mis-operations which are not in compliance with "User Manual";

② Damages incurred to the drive due to fire, flood, abnormal voltage and so on;

③ Damages incurred to the drive due to the improper use of drive functions;

4. Service fee will be charged according to the actual costs. If there are any maintenance contracts, the contract prevails.

60 Appendix 1 Parameter Set

EV1000 Series General Purpose Variable Speed Drive User Manual

Appendix 1 Parameter Set

EV1000 Series drive’s parameters are organized in groups. Each group has several parameters that are identified by “Group No.+ Parameter SN.”. Parameter F X.YZ denotes that the parameter belongs to group “X” and its SN is “YZ”. For example, “F5.08” belongs to group 5 and its SN is 8.

For the convenience of setting the parameters, the group number corresponds to the menu level, 1, parameter number corresponds to menu level 2 and parameters of parameter correspond to the menu level 3.

The setting of parameter is presented in decimal (DEC) and hexadecimal (HEX) format. If it is set in hexadecimal format, each digit of the setting is independent to one another.

Explanation of the columns in Parameter Table:

The “LCD display” in third row refers to the parameter’s name displayed by LED; The “setting range” in fourth row is the valid ranges of parameter settings; The “minimum unit” is the min. value of the parameter; The “factory setting” in sixth row is the primary factory settings; The “modification” in seventh row is the properties of modification (that is, whether it is allowed to be modified and conditions for modification) :

“O” denotes the parameters can be revised when the drive is in operating or stop status;

“ × ” denotes the parameters can not be revised when the drive is operating;

“*” denotes the parameters are actually detected and can not be revised;

“-” denotes the parameters that are set by factory and the user cannot modify it;

(The drive has already set the “auto-checking” function to the modification property of each parameter, so as to avoid wrong modification by the user.)

The drive provides passwords to protect the parameters against unauthorized modifications. After the user’s password is set (that is, the settings of FP.00 are not zer o) ,

the drive will require you to input the password before the user press the MENU/ESC to edit the parameter settings, otherwise you cannot set the parameters. For the parameters set by factory, you can only set the parameters after inputting factory password (you should not change the settings of the parameters set by factory because the drive may operate abnormally or may be damaged if the parameters are not set correctly) .

After setting the password, please don’t press the keys within 5 minutes so as to enable the password. If the password is input correctly and the keys have not been pressed for longer than 5 minutes, the drive will be locked by the password again. The user’s password can be changed any time if the password protection is not locked up. The password that is input last time is valid.

The user’s password can be disabled by setting FP .00 to 0. If FP.00 is not set to 0, then the parameters will be protected by the password.

Attention

It is defaulted that no parameters except F0.02 are allowed changing. If you need change them, please first set FP.01(parameter write-in protection) from 1 to 0.

2. Communication Mode

RS485: asynchronous, half-duplex Default: 8-N-2, 19200bps. See Group FF parameter settings.

1) The protocol is Modbus protocol. Besides the common register Read/Write operation, it is supplemented with commands of parameters management.

2) The drive is a slave in the network. It communicates in ‘point to point’ master-slave mode. It will not respond to the command sent by the master via broadcast address.

3) In the case of multi-drive communication or long-distance transmission, connecting a 100~120Ωresistor in parallel with the master signal line will help to enhance the immunity to interference.

3. Protocol Format

Modbus protocol support both RTU and ASCII mode. The frame format is illustrated as follows:

cheksum

RTU mode

Modbus data frame

Start, at least 3.5

bytes idle time

Slave (drive) address

Function

code

End, at least 3.5

bytes idle time

checksum

ASCII mode

Modbus data frame

Start: "0x3A"

Drive (slave)

address

Function code

Data

End: "0xD, 0xA"

Modbus adopts “Big Endian” Representation for data frame. This means that when a numerical quantity larger than a byte is transmitted, the most significant byte is sent first.

Under RTU mode, the idle time between frames is decided by the bigger value between parameter setting by FF.03 and the Modbus minimum idle time. The minimum Modbus idle time between frames should be no less than 3.5 bytes. The checksum adopts CRC-16 method. All data except chekcsum itself sent will be counted into the calculation. Please refer to section: CRC Check for more information.

Note that at least 3.5 bytes of modbus idle time should be kept, and the start and end idle time need not be summed up to it.

The table below shows the data frame of reading parameter 002 from Drive No. 1.

The table below shows the reply frame from Drive No. 1.

EV1000 Series General Purpose Variable Speed Drive User Manual

Address Parameter Reply bytes Register content Checksum

0x01 0x03 0x02 0x13 0x88 0xB5 0x12

In ASCII mode, the frame head is “0x3A”, and default frame tail is “0x0D” or “0x0A”. The frame tail can also be configured by users. Except frame head and tail, other bytes will be sent as two ASCII characters, first sending higher nibble and then lower nibble. The data have 7 bits. “A”~“F” corresponds to the ASCII code of respective capital letter. LRC check is used. LRC checksum is calculated by adding all the successive 8-bit bytes of the message except the head and tail, discarding any carriers, and then complementing the result.

Example of Modbus data frame in ASCII mode: The command frame of writing “4000 (0xFA0) ” into Register

002 of Drive No. 1 is shown in the table below: LRC checksum=the complement of

(01+06+00+02+0x0F+0xA0) = 0x48

Different respond delay time can be set through drive’s parameters to adapt to different needs. For RTU mode, the respond delay time should be no less than 3.5 bytes interval, and for ASCII mode, no less than 1ms.

4. Protocol Function

The main functions of Modbus is to read and write parameters. The Modbus protocol supports the following function code:

Function code Function

0x03

Read drive’s parameter and operation status parameters

0x06

Modify single drive’s parameter or control parameters. Not save them upon power-off.

0x08 Serial line diagnosis 0x10

Modify several drives’ parameter or control parameters. Not save them upon power-off.

0x41

Modify single drive’s parameter or control parameters. Saving them upon power-off.

0x42 Parameter management

All drive’s parameters, control and status parameters are mapped to Modbus R/W Register. The R/W properties of the parameters and their setting ranges are specified in the user manual. The group number of the drive’s parameter maps to the most significant byte of the register address, and the index number of the parameter in the group maps to the least significant byte. The control and status parameters of the drive are virtually taken as parameter group. The relationship of group number of the parameters and the most significant byte of register address is listed below:

F0 group: 0x00; F1 group: 0x01:

F2 group: 0x02; F3 group: 0x03; F4 group: 0x04; F5 group: 0x05; F6group: 0x06; F7 group: 0x07; F8 group: 0x08; F9 group: 0x09; FA group: 0x0A; Fb group: 0x0B; FC group: 0x0C; Fd group: 0x0D; FE group: 0x0E; FF group: 0x0F; FH group: 0x10; FL group: 0x11; Fn group: 0x12; FP group: 0x13; FU group: 0x14; Drive control parameter group: 0x32; Drive status parameter group: 0x33. E.g. the register address of F3.02: 0x302, register address

of FF.01: 0xF01. The above shows the format of the frame. Now we will

introduce the Modbus function code and data unit for different function in details, which is called protocol data unit for simplicity. Also MSB stands for the most significant byte and LSB stands for the least significant byte for the same reason. The description below is data format in RTU mode. The length of data unit in ASCII mode should be doubled.

Parameter 0x41 is to modify single drive’s parameter or control parameter and save it in an involatile memory. The format is similar with that of 0x06. The only difference is that 0x41 parameter is saved upon power failure, while 0x06 not. Since some of the control parameters cannot be saved in the involatile memory, the two commands in this case have the same effect. Those parameters will be introduced later.

The management of parameters includes reading out the upper and lower limit of the parameters, parameters properties, max. index number of a parameter group, next or previous parameter group number, currently displayed status parameter index, or display the next status parameter. Parameter property includes R/W property, parameter unit, scaling, etc. These commands are helpful to provide information about parameter’s range and properties etc., which are necessary for modifying parameters remotely. The protocol data unit of parameter management is as follows:

Request format:
