1.3 Notes for Using EV2000

Pay attention to the following issues when using EV2000 drive.

1.3.1 About Motor and Load

Compared to the power frequency operation

EV2000 series drives are voltage type variable speed drive. The output voltage is in PWM wave with some harmonics. Therefore, temperature rise, noise and vibration of motor are higher.

Low Speed Rotating with Constant Torque

Driving a common motor at low speed for a long time, the drive’s life will be reduced due to the deteriorating heat dissipation effect, so a special variable frequency motor is needed if long time operation with constant torque is required.

Motor’s over-temperature protecting threshold

The drive can protect the motor from over-temperature. If the ratings of the driven motor are not in compliance

EV2000 Series Universal Variable Speed Drive User Manual

Chapter 1 Safety 3

with the drive, be sure to adjust the protective threshold 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 proportional 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.

Braking Torque

Braking torque is developed in the machine when the drive is hoisting a load down. The drive will trip when it cannot cope with dissipating the regenerative energy of the load. Therefore, a braking unit with proper parameters setting in the drive is required.

The 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 been set to avoid it.

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

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. Wiring diagram is shown in Fig. 1-1. Please use 500V insulation tester to measure the insulating resistance. It should not be less than 5MΩ.

1.3.2 About Variable Speed Drive

Varistors or Capacitors 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, otherwise tripping or damaging of components may occur; in addition, don't install circuit breaker or contactor at the output side of the drive as shown in Fig.1-2.

EV2000

Fig. 1-2 Capacitors are prohiBited to be used.

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 outside the range of 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.

Change from 3-phase to 2-phase

It is not recommended to change the drive from 3-phase input to 2-phase input. If it is necessary to use on two phases, the phase-loss protection function of the drive should be disabled. The Drive must be derated for this operation. For motors at which power is above 30kW, if it is changed into 2-phase input, then the input phases must be at phase R and phase T, or else the drive will not work.

After the 3-phase input is changed into 2-phase input, bus-voltage and current ripple may increase, which not only influences the life of electrolytic capacitor but it also deteriorates the performance of the drive. The drive’s operating current should be derated and should not exceed 67% of rated value.

Protection against lightning strike

There are transient surge suppressors inside the Drive which protects it against lighting strike.

EV2000 Series Universal Variable Speed Drive User Manual

4 Chapter 1 Safety

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 Drive is deteriorated due to the thin air, as shown in Fig.1-3 that indicates the relationship between the elevation 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.

3.3 Wire Connections of Drive

Danger

·Wiring can only be done after the drive’s AC

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

·Wiring job can only be done after confirming the

charge indicator on the right bottom 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.

·Check the drive’s voltage level before supplying

power to it, otherwise human injuries 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, so you need not do it again.

·Refer to chapter 2 on connected 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

section area bigger than 3.5mm grounding resistance should be less than 10Ω.

·There is leakage current inside the drive. The total

leakage current is greater than 3.5mA, depending on the usage conditions. To ensure safety, both the drive and the motor should be grounded, and a leakage current protector (RCD) should be installed. It is recommended to choose B type RCD and set the leakage current at 300mA.

·The drive should be connected to the AC supply

via a circuit breaker or fuse to provide input over-current protection or convenience for disconnecting the AC supply to maintain the drive.

4). DC reactor

DC reactor is required for the drive whose power is greater than EV2000-4T0750G, for the drive whose power is lower than EV2000-4T0750P, it is optional.

Under following conditions, a DC reactor should be used to reduce the impact of AC supply to the drive and to protect the drive and suppress the high-order harmonics.

(1) If a capacitor tank used for reactive power compensation or a SCR load shares the same AC supply with the drive, the harmonics caused by the SCR load or the capacitor tank when it is switched on or off may damage the drive’s input rectifying circuit;

(2) When the unbalance rate of 3-phase AC supply of the drive is greater than 3%;

(3) If the input power factor of the drive is required to be greater than 0.93;

(4) When a large capacity transformer is connected to the drive, the input current of the drive may damage the rectifying circuit. Generally, if the input AC supply capacity of the drive is above 550KVA, or if the input AC supply capacity is 10 times that of the drive, a DC reactor is required to connect to the drive.

(5) 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.

6) Output AC Line Reactor

When the cables from the drive to motor are longer than 80m, multi-stranded cables and an AC line reactor should be used to suppress the high frequency harmonics. Thus, the motor insulation is protected against heat due to harmonics, leakage current is reduced and the drive will not trip frequently.

(7) Input EMI filter

An EMI filter can be used to suppress the high frequency noise generated by the drive’s power cables.

(8) Output EMI filter

An EMI filter can be used to suppress the drive’s output noise and leakage current of cables.

(9) Safety ground

Since there is leakage current inside the drive, to ensue

safety, both the drive and the motor should be grounded, the grounding resistance should be less than 10Ω. The ground wire should be as short as possible. Please refer to the section of the earth wire in Table 3-2.

 Notes:

1. EV2000 drive can meet the requirements of IEC 61800-3 after EMI filter is installed.

2. Installation of input and output EMI filters must be as close to the drive as possible. Refer to Section 3.4 of Chapter 3 for EMC installation instructions.

 Notes:

1. Terminal CCI can be input voltage or current signal by switching the jumper CN10 on control board;

2. The auxiliary power supply’s AC supply comes from R0 and T0 which are shorted with R and T of 3-phase input. If you want to use an external AC supply, the shorting bars between R and R0, T and T0 have to be removed before connecting the external AC supply via R0 and T0. Otherwise, short-circuit will occur.

3. It is prohibited to connect to the control power supply without disconnecting the short-circuit bar, so as to avoid short-circuit accident;

4. If external braking parts are needed, then braking kit and braking resistors should be included; Pay attention to the polarity of the braking kit when wiring;

5. In the above figure, “O” is the terminal in main circuit, and “⊙” is the control terminal;

6. Refer to section 3.3.2 for the using of control terminals.

Notes:

(1) When using analog input, a common mode inductor can be installed between VCI and GND or CCI and GND. (2) Analog input and output signals are easily disturbed by noise, so shielded cables must be used to transmit these signals and the cable length should be as short as possible.

3. Wiring of Serial Communication Port

Wire connections of serial communication port.

EV2000 drive provides two kinds of serial ports: RS232 and RS485 which can be selected by Jumper CN14.

Wire as following figures show, and a “single-master single slave” system or a “single-master multi-slaves” system can be formed. The drives in the network can be monitored and controlled remotely and automatically in real time by using a PC or PLC controller. Thus more complicated operation control can be realized (e.g. Unlimited multi-step PLC operation).

If several drives are connected in the network via RS485, the disturbance to the communication system increases, so the wiring is especially important, you can connect the cables according to the figure below:

Fig. 3-21 Communication between PLC and the drive (the drive and motor are grounded well)

If the communication is still abnormal, then the following actions can be taken:

①

Feed a separate AC supply to the PLC(or host PC) and isolate the AC supply;

②

If RS485/RS232 conversion module is used, then the module should be powered by a separate power supply;

③

Mount magnetic core to the communication cable, reduce the carrier frequency if the field conditions permit.

3.4 Installation Methods Compliant With

EMC Requirements

The drive inevitably generates noise due to its high switching frequency, so relevant EMC problems must be solved so as to reduce the drive’s disturbance to external equipment. This chapter deals with the installation methods compliant with EMC requirements from the aspects of noise suppression, field wiring, grounding, leakage current and the using of power filter. This chapter can be used as a reference for field installation.

3.4.1 Noise Suppressing

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, wiring, installation clearance and earthing methods.

1. Noise categories

Noise

3) Wiring relay output terminals TA, TB and TC.

If the drive drives an inductive load (such as relay or contactor), then a surge suppressing circuit should be added, such as RC snub circuit (pay attention that the leakage current must be smaller than the holding current of the controlled relay or contactor) and varistor or a free-wheeling diode (used in the DC electric-magnetic circuit and pay attention to the polarity during installation). Snubbing components should be as close to the coils of relay or contactor as possible.



Notes:

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

2. Please use multi-core shielded cable or multi-stranded 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) from the main circuits and high voltage cables as possible (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.

5. The resistors R in Fig. 3-27 and Fig.3-28 should be removed for 24V input relays, and the resistance of R should be selected according the parameters of relay for non-24V relay.

Take the following actions to solve this problem: 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. Take the actions below to solve the problem: (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

④⑤⑥

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 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).

paths

Don’t route the signal cables in parallel with the power cables or bundle these cables together because the induced electro-magnetic noise and induced ESD noise may disturb the signal cables. Other equipment should also be located as far away as possible from the drive. The signal cables should be placed

①⑦⑧

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.

3.4.2 Field Wire Connections

Control cables, input power cables and motor cables should be installed separately, and enough clearance should be left among the cables, especially when the cables are laid in parallel and the cable length is big. If the signal cables must go through the power cables, they should be vertical to each other.

The motor cables should be derated if they are too long or their cross sectional area (CSA) is too big. The drive’s cables should be the cables with specified CSA (See Table 3-1) because the capacitance of the cable to ground is in proportional to the cable’s CSA. If the cable with big CSA is used, its current should be reduced.

Shielded/armoured cable: High frequency low impedance shielded cable should be used. For example: Copper net, aluminum net or iron net.

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

EV2000 Series Universal Variable Speed Drive User Manual

34 Chapter 3 Installation and Wiring

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 to the drive as possible.

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

3.4.4 Installation Requirements of Relay, Contactor and

Electro-magnetic Braking Kit

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

and relays falsely activated. The higher the drive’s carrier wave frequency, the bigger the leakage current, also, the longer the motor cable, the greater the leakage current,

Suppressing methods:

Reduce the carrier wave frequency, but the motor noise may be louder;

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 through the distribution capacitors of the drive out side may cause the thermal relay falsely activated, especially for the drive whose power is lower than 7.5kW. When the cable is longer than 50m, the ratio of leakage current to motor rated current may be increased that can cause the wrong action of external thermal relay very easily.

Suppressing methods:

Reduce the carrier wave frequency, but the motor noise may become louder;

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.

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.

3.4.6 Correct EMC Installation

Divide the installation space into different areas

In driving system, the drive, control equipment and sensors are installed in the same cabinet, the noise should be suppressed at the main connecting points with the RFI filter and input reactor installed in cabinet to satisfy the EMC requirements.

The most effective but expensive measure to reduce the interference is to isolate the noise source and the noise receiver, which should be considered in mechanical/system design phase. In driving system, the noise source can be drive, brake unit and contactor. Noise receiver can be automation equipment, coder and sensor.

The mechanical/system is divided into different EMC area according to its electrical characteristics. The recommended installation positions are shown in the following figure:

Attention:

Area Ⅰshould be used to install transformers of

Area Ⅱ should be used for interfaces of signal and

control cables, correct immunity level is required.

Area Ⅲ should be used to install noise sources such

as input reactor, the drive, brake unit and contactor.

Area Ⅳ should be used to install output noise filter

and the wires of filter.

Area Ⅴ should be used to install power source and

cable connecting parts of RFI filter.

Area Ⅵ should be used to install motor and motor

cables.

Areas should be isolated in space, so that

electro-magnetic decoupling effect can be achieved.

The minimum distance between areas should be 20cm.

Earthing bars should be used for decoupling among

areas, the cables from different area should be placed in different tubes.

The filter should be installed at the interfaces between

different areas if necessary.

Fig. 3-44 Installation of the drive

Motor cable should be earthed at the drive side, if

possible, the motor and drive should be earthed separately;

Motor cable and control cable should be shielded or

armored. The shield must be earthed and avoid entangling at cable end to improve high frequency noise immunity.

Assure good conductivity among plates, screw and

metal case of the drive; use tooth-shape washer and conductive installation plate;

Generally, if there are some sensitive equipment, it is more cost-effective to install the power filter at sensitive equipment side.

3.4.7 Application of Power Line Filter

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

Function of power line filter

Metal cabinet

Motor

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

EV2000 Series Universal Variable Speed Drive User Manual

36 Chapter 3 Installation and Wiring

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

Common mistakes in using power cable 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 filter will become ineffective.

3. Bad earthing of filter

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

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

3.4.8 EMI of The Drive

The drive’s operating theory decides that its EMI is unavoidable.

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

If you install the drive and other control equipment in one cabinet, the area rule must be observed. Pay attention to the isolation between different area, cable layout and shielding..

Chapter 4 Operation Instructions

4.1 Notice

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 The Drive’s Control Modes

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

Panel control: The drive is controlled by RUN, STOP and JOG keys on the operation panel;

Terminal control: The drive is controlled by terminals FWD, REV and COM (2-wire mode), or by terminal Xi (3-wire mode);

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

The control modes can be selected by parameter F0.03, PANEL/REMOTE key and ENTER/DATA key on the operation panel and multi-function input terminal (No.27, 28 and 29 can be selected by F7.00~F7.07).

setting methods, 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 Fig. 5-59 in chapter 5.

4.1.3 Operating Status

There are 3 operating status: stopping, motor parameters auto-tuning, and operating.

Stopping status: After the drive is switched on and initialized, if no operating command is accepted or the stopping command is executed, then the drive enters stopping status.

Operating status: The drive enters operating status after it receives the operating command.

Motor parameters auto-tuning status: If there is an operating command after FH.09 is set to 1 or 2, the drive then enters motor parameters auto-tuning status, and then enters stopping status after auto-tuning process is over.

4.1.2 Reference Selector

In common operating modes, EV2000 has 6 possible ways to input reference frequency, the reference frequency can be input by:

Interval of Jog operation (F3.14) is the interval from the time when the last Jog operation command is ended to the time when the next Jog operation command is executed.

The jog command sent during the interval will not be executed. If this command exists until the end of the interval, it will be executed.

Note:

1. In Jog operation process, the drive starts according to starting mode 0 and stops according to stopping mode 0. The unit of Acc/Dec time is second.

2. Jog operation can be controlled by panel, terminals and serial port.

Range: 0.1~3600s(min) 【6.0s/20.0s

Three kinds of Acc/Dec time can be defined, and the drive’s Acc/Dec time 1~4 can be selected by different combinations of control terminals, refer to the introductions of F7.00~F7.07 for the definitions of terminals used to select Acc/Dec time.

Note:

1. Acc/Dec time 1 is defined in F0.10 and F0.11.

Note:

When the PLC operating direction is determined by operating commands, the direction of the motor can be controlled by external terminals. For example: to run forward by closing FWD-COM terminal, and run reverse by closing REV-COM. If no command is given, the drive will run in the direction of last stage.

5.6 Close-loop Control Parameters(Group F5)

There are two kinds of close loop control: analog close-loop control (feedback value is analog value) and pulse close-loop control (feedback value is pulse). Fig. 5-29 and 5-30 show the typical wiring of analog close-loop control and pulse close-loop control respectively.

Fig. 5-30 Wiring of speed close-loop with PG

As shown in Fig. 5-29, pressure reference (voltage signal) is input via terminal VCI, while the feedback pressure value is input into terminal CCI in the form of 0(4)~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) in close speed-loop control

Close speed-loop using PG:

A close speed-loop control system uses external control terminals X

and X8, and pulse generator(PG).

As shown in Fig. 5-30, reference of speed close-loop can be input by 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 terminals X7 and X8. The start and stop of the drive can be controlled by terminal FWD.

In Fig. 5-30:

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 is in direct proportion to synchronous speed n and f

that corresponds to 0~Max frequency (F0.05),

is Max frequency (F0.05), and P is the number

max

of poles of motor(FH.00).

=120×f

Refer to F7.00~F7.07 for the functions of input terminals X7 and X8.



Note:

max

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

2. Dual-phase input is good for improving the speed measurement accuracy, while the wiring of single-phase input circuit is simple;

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

4. If using the drive’s terminal P24 to supply the power to PG, then the Max load current of optical PG must be less than 100mA.

Operating principles of internal PI of EV2000 is shown in the Fig. 5-301.

Analog feedback control system:

An analog feedback control system uses a water-level sensor as the feedback sensor of the internal PI.

There are two features of internal PI of EV2000:

The relationship between reference and feedback can be defined by F5.08~F5.11.

For example: In Fig. 5-29, if the reference is analog signal of 0~10V, the controlled value is 0~1MP, and the signal of water-level sensor is 4~20mA, then the relationship between reference and feedback is shown in Fig. 5-32.

Feedback

Reference

Fig. 5-32 Reference and feedback

The reference value is a 0~10V signal (10V corresponds to 100%); and the feedback value is 4Ma~20mA (20mA corresponds to 100%).

In Fig 5-31, “reference regulation” and “feedback regulation” mean that the reference value and feedback value are converted from current or voltage value to percentage values, so that feedback value can be added to or subtracted from the reference value.

Close-loop reference is selected via F5.16 to satisfy different application requirements.

If the motor’s speed is required to increases with the reference speed, this kind of control characteristic is called positive characteristic. If the motor speed is required to decrease when the reference value increases, this control characteristic is called negative characteristic.

Please refer to Fig. 5-33 and F5.16.

The relationship between close-loop reference and feedback value (F5.08~F5.11) should be defined for close-loop control;

For speed close-loop, the close-loop speed reference and the number of revolutions of PG (F5.06~F5.07) need to be determined;

Determine the close-loop regulation characteristic, i.e. whether the motor speed increase with the reference. Please see F5.16.

Set up the integral regulation function and close-loop frequency presetting function (F5.17~F5.19);

Traverse operation is widely used in textile and chemical fiber industry. The typical application is shown in Fig. 5-37.

Traverse operation process: First, the drive accelerates to the preset frequency of traverse operation (F6.02) within the Acc time and then waits for certain time (F6.03). The drive transits to the central frequency within Acc/Dec time, and at

The central frequency is actually the preset frequency of simple operation (except PLC, traverse operation, jog), multi-step speed operation or PLC operations;

Traverse operating function is disabled automatically in Jog operation or close-loop operation process.

If PLC operation and traverse operation start at the same time, the traverse operation is disabled when the drive transits from one PLC operating stage to another stage. The drive will accelerate to the preset frequency of PLC operation and then start traverse operation. The drive will decelerate to stop within the Dec time set in PLC operating stage.

F7.35 defines the terminal’s positive and negative logic

Positive logic: Terminal Xi is enabled if it is connected to the common terminal;

Negative logic: Terminal Xi is disabled if it is connected to the common terminal;

If the bit is set at 0, it means positive logic; if set at 1, it means negative logic.

For example:

If X1~X8 are required to be positive logic, terminals FWD and REV are required to be negative logic, terminal Y1 is positive logic and terminal Y2 is negative logic, then the settings:

Logic status of X4~X1 is 0000, and the hex value is 0; Logic status of X8~X5 is 0000, and the hex value is 0,; Logic status of Y2, Y1, REV and FWD is 1011, and the hex value is B, so F7.35 should be set at “0B00”. Refer to Table 5-13.

In Fig. 5-68, a drive drives a motor that rotates a spindle via a conveyor belt. Speed measuring device measures the line speed of the spindle and send the speed signal to the drive in the form of pulses. The drive will count the pulses and calculate the actual length. If the actual length is longer than the preset length, the drive will stop the motor automatically. The operator can remove the spindle and close the terminal that is defined as function 39 to clear the length, and then restart and produce the next spindle.

Trip-free operating function enables the drive to perform low-voltage compensation when the voltage drops or instantaneous under-voltage occurs. The drive can continue to operate without tripping by reducing its output frequency and feedback energy via motor.

If F9.20 is set to 0, this function is disabled.

If F9.20 is set to 1, this function is enabled and low-voltage compensation is activated.

If F9.21 (frequency decrease rate at voltage compensation) is set too big, the feedback energy of motor will be too large and over-voltage protection might be activated; If F9.21 is set too small, the feedback energy of motor will be too small to achieve voltage compensation effect. So, please set F9.21 according to load inertia and the actual load.

When using the panel or serial port or 3-wire modes 1 and 2 to start or stop the drive, the command signal is in pulse mode and there is no operating command when the drive is switched on. If there is a stopping command, the drive will stop first. When the function of restart after power failure is enabled, the drive will start on the fly after power on if it is not switched off totally (that is, the motor still runs and drive’s LED displays “P.OFF”). It will start in the starting mode defined in F2.00 after power on if it is switched off totally (LED turns off). For 2-wire mode 2, there is control command after power-on.

The setting of thousand’s Bit does not affect the communication process. If FF.00 is set to MODEM (RS232) mode, the MODEM will be initialized via the RS232 port each time when the drive is switched on, so that the MODEM can answer the call automatically after it receives 3 ringing signals. See section 3.3.2 in chapter for the wiring of remote control circuit formed by dialed circuits.

FF.01 Local address

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

Note: “127” 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 the PC.

FF.02 Time threshold for judging communication status

If the drive has not detected the communication signal from the serial port for certain time, it will judge that communication failure occurs. The time threshold is defined by FF.02.

If FF.02 is set to 0, the drive will not detect the communication signal of serial port and this function is disabled.

The function can enable auto tuning of motor’s parameters and write the results in the related parameters automatically.

0: Auto-tuning is disabled

1: Stationary auto-tuning (Start auto-tuning to a standstill motor)

Values on the motor’s nameplate must be input correctly before starting auto-tuning.

When starting auto-tuning to a standstill motor, the stator’s resistance (%R1), rotor’s resistance (%R2) and the leakage inductance (%X1) will be detected and written into FH.04, FH.05 and FH.06 automatically.

2: Rotating auto-tuning

When starting a rotating auto-tuning, the motor is in standstill status at first, and the stator’s resistance (%R1), rotor’s resistance (%R2) and the leakage inductance (%X1) will be detected, and then the motor

will start rotating, exciting inductance (%Xm and I

will be detected. All the above parameters will be saved in 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.

4. Remove the load from the motor and check the safety;

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

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



Note:

When setting FH.09 to 2, Acc/Dec time can be increased 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 first 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; In some applications, for example, the motor cannot break away from the load or if you have no special requirement on motor’s control performance, you can select stationary auto-tuning. You can also give up the auto-tuning. At this time, please input the values on the motor’s nameplate correctly (FH.00~FH.02). If the auto-tuning cannot be applied and the correct motor’s parameters are available, the user should input the values on the motor’s nameplate correctly (FH.00~FH.02), and then input the calculated values (FH.03~FH.07). Be sure to set the parameters correctly. If auto-tuning is not successful, the drive will alarm and display fault code E024.

Auto current limiting function is used to limit the load current smaller than the value defined by FL.07 in real time. Therefore the drive will not trip due to surge over-current. This function is especially useful for the applications with big load inertia or big change of load.

FL.07 defines the threshold of auto current limiting. It is a percentage of the drive’s rated current. It is default 150% for G type and 110% for P type.

FL.08 defines the decrease 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 it is set too big, the frequency will change too sharply and therefore, the drive may be in generating status for long time, which may result in overvoltage protection.

Auto current limiting function is always active in Acc or Dec process. Whether the function is active in constant speed operating process is decided by FL.09.

3. Check whether the power cables and control cables are damaged, check especially for any wear on the cable tube;

4. Check 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 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

Notes:

Dielectric strength test of the drive has already been conducted in the factory. Do not do the test again, otherwise, the internal components might be damaged.

7.3 Replacing Wearing Parts

The components that are easily damaged are: cooling

fan and electrolytic capacitors of filters. Their lifetime

depends largely on their application environment and

preservation. Normally, lifetime is:

Components Life

Fan 3~40,000 hours

Electrolyte capacitor 4~50,000 hours

You can decide the time when the components should

be replaced according to their service time.

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. Check if the safety valve protrudes. Measure static capacitance and insulation resistance.

7.4 Storage

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 at least for 5 hours. The input voltage must be boosted gradually by the voltage regulator to the rated value.

7.5 Warranty

Emerson Network Power will offer warranty service in the case of the following situations:

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

2. Emerson Network Power will take the responsibility of 18 months defects liability period for any faults or damages under the normal operation conditions. After 18 months, maintenance will be charged;

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

4.Damages incurred to the drive due to incorrect operation, 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;

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

90 Appendix 1 Parameters

Appendix 1 Parameters

EV2000 series drive’s parameters are organized in

groups. Each group has several parameters that are

identified by “Group No.+ Function Code. For example,

“F5.08” belongs to group 5 and its function code is 8.

For the convenience of setting, parameter group number

corresponds to the first level menu, parameter

sub-group corresponds to the second level menu and

parameter value corresponds to the third level menu.

The parameter descriptions are listed in the tables

below.

Note:

1. The “modification” column in the parameter table

means whether the parameter can be modified.

“O” denotes the parameters can be modified during

operation or at STOP state;

” denotes the parameters cannot be modified during

“

operating;

“*” denotes the parameters are actually detected and

cannot be revised;

“-” denotes the parameters are defaulted by factory and

cannot be modified ;

When you try to modify some parameters, the system

will check their modification property automatically to

avoid mis-modification.

Parameter settings are expressed in decimal (DEC) and

hexadecimal (HEX). If the parameter is expressed in

hexadecimal, the bits are independent to each other.

The value of the bits can be 0~F.

In the tables, “LCD display” is available only for the drive

with LCD keypad

“Factory settings” means the default value of the

parameter. When the parameters are initialized, they will

resume to the factory settings. But the actual detected or

recorded parameters cannot be initialized;

The parameters can be protected against unauthorized

modifications by password. After the user’s password is

set up (FP.00 is not set to zero), you are required to

input password when you press MENU/ESC to enter

menu. For the parameters exclusive for factory use, you

cannot change them.

After the password is set, if no keypad operation within 5

minutes, the modification of parameters will be protected

by password. You can modify the password at any time.

The last input password is valid.

The user’s password can be disabled by setting FP.00 to 0.

The above rules should be observed when changing the password or setting the parameters via the serial port.

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.
