4.5.2.2 Braking Unit and Braking Resistor

• CHV invertor of 15kW and below has braking unit installed inside. In order to release the feedback energy generated during braking, braking resistor must be installed and connected at the (+) and PB terminal.

• Braking resistance should have a wire length less than 5M.

• As braking resistor can release energy and increase the temperature, safety protection and good ventilation should be provided when the braking resistor is being installed.

• CHV inverter of 18.5kW or higher has external braking unit. In order to release the feedback energy generated during braking, braking units must be installed and connected at

(+) and (-) terminals, and braking resistor must be installed and connected at the (+) and PB terminals.

• The wire connecting (+), (-) terminals of inverter and (+), (-) terminals of braking unit should have a length less than 5 meters. The wire for (+), PB terminals of braking unit and braking resistor should have a length less than 10 meters.

Caution: Be sure of electric polarity of (+), (-) , and DO NOT misconnect them; it is not allowed to directly connect (+), (-) terminals to braking resistor, otherwise there will be a risk of inverter damage or fire.

4.5.3 Wiring at Motor side of Main Circuit

4.5.3.1 Output Reactor

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 20

In the case that the distance between inverter and motor is more than 100 meters, as long cable can have parasitic capacitance to ground and cause large current leakage, so the inverter will have frequent over-current protection, it is necessary to add output reactor to compensate this fact, and in the meantime to avoid damage to motor insulation.

4.5.3.2 Noise Filter at Output Side

Noise filter installed at the output side can minimize current leakage at the connecting wire and the wireless noise caused by cable between inverter and motor. Its Connection is shown in following diagram.

Figure 4-7 Wiring Diagram at Motor Side of Main Circuit

4.5.4 Feedback Unit Wiring

Feedback unit can feed back the electricity generated by regenerative braking of motor to the grid. CHV feedback unit uses IGBT as the rectification feedback, which, if compared with traditional 3 phase inverse parallel bridge-type rectification unit, has an allocation of feedback harmonic wave distortion less than 4% of first harmonic, and thus causes less pollution to the grid. Feedback unit is extensively used at oil field for pumping unit, centrifugal machine and hoister and so on.

4.5.5 Wiring of common DC bus

For multiple motors application for paper manufacturing machinery and chemical fiber industry, common DC bus is normally used. At any time, some motors are in operating condition while some others are at regenerative braking (generating electricity) condition. In this case the regenerated electricity is automatically balanced at the DC bus and can be supplied to motors at operating condition, reducing the electricity consumption of the whole system from the grid, more energy saving than traditional single inverter for single motor. Its wiring diagram is shown as following figure:

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 21

Figure 4-8 Wiring of common DC bus

When two motors are at operation at the same time (such as windin motor unreeling motor). In this case the DC buses of the two inverters can be connected in parallel so that the regenerated electricity can be supplied to motors at electromotion to save energy. Its detail wiring is shown as following figure:

Wiring of Common DC Bus

4.5.6 Ground Connection (PE)

In order to ensure safety and prevent electrical shock and fire, inverter s ground terminals PE must be earth connected with ground resistance less than 10 . As earth wire should be big and short, it is better to use wire with multiple copper core. When multiple inverters need to be earth connected, it is suggested for them as many as possible not to use common earth wire to prevent the earth wire looping in.

4.6 Control Circuit Connection

4.6.1 Precautions

Please use multiple core shielding cable or shield twisted pair (STP) to connect the control terminals. The shielding cable should be connected with the inverter earth terminals PE if it is applied at the inverter side. The wire arrangement should make sure that control cables are more than 20cm far away from the main circuit and heavy current circuits (including power supply cable, motor cable, relay and contactor connecting cable), and parallel arrangement should be avoided. It is suggested to apply perpendicular arrangement to prevent inverter malfunction caused by external interference.

4.7 Installation Guide Based On EMC Requirements

4.7.1 General Description of EMC

EMC is the abbreviation of electromagnetic compatibility, which means the device or system has the ability to work normally under electromagnetic environment, and it does not produce electromagnetic interference to any thing in this environment. EMC includes two subjects: electromagnetic interference and electromagnetic anti-interference.

According to the route of transmission, electromagnetic interference has two categories: conducted interference and radiated interference

Conducted interference is the interference transmitted by conductor and therefore, any conductor, such as wire, transmission line, inductor, capacitor and so on, is the transmission

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 23

channel of interference.

Radiated interference is the interference transmitted in electromagnetic wave manner, and the energy it transmits is inversely proportional to the square of distance.

Electromagnetic interference generation must have three conditions or called-as three essential elements: interference source, transmission channel and sensitive receiver, any of which is essential. Solutions for EMC are based on these three. For customers, as the fact the device is interference source or receiver, the solution for EMC should start at the transmission channel.

Different electric or electronic devices are manufactured based on different EMC standard or class, and have different EMC ability.

4.7.2 EMC Features of inverter

Inverters, like other electric or electronic devices installed in a power distribution system, is a electromagnetic interference source and a electromagnetic receiver as well. The operating principle of inverter determines that it can produce certain electromagnetic interference noise, and in order to ensure that it works reliably in certain electromagnetic environment, its design gives it certain ability of anti-interference. When it is in operation, its EMC features include:

4.7.2.1 Input current is normally nonsinusiodal wave including plenty of higher harmonic waves which may produce electromagnetic interference reducing grid power factor and increasing wire loss.

4.7.2.2 Output voltage is high frequency PMW wave, which can have effect on motor temperature increase, reducing motor service life and increasing current leakage which make the leakage protection device malfunction, and in the same time generating strong electromagnetic interference and having effect on reliability of other electric devices.

4.7.2.3 As an electromagnetic receiver, receiving too strong interference from outside can make inverter malfunction or even damaged.

4.7.2.4 In system wiring, interference generated by inverter and its anti-interference supplement each other. The process reducing its interference from outside can increase it anti-interference ability.

4.7.3 EMC Installation Guide

In order for all electric devices in the same system to work reliably, this section, based on

EMC features of inverter and for site installation reference, introduces its detail installation process on noise control, site wiring, grounding, leakage current and power supply filter application. Only these five jobs well done can derive good effective EMC.

4.7.3.1 Noise Control

The wires connected to all control terminals of inverter are shielding wires, which, at cable entry of inverter, connect the shielding layer to the ground at the nearest point by means of

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 24

360 trombone connection formed by cable clips. It is strictly prohibitive to twist the shielding layer into braid and to connect it to the ground of inverter, which greatly decreases the shielding effect and even lose the shielding effect.

The wires connecting the inverter and motor should be shielding wires or go through separated cable tray. The shielding layer of motor wires or one end of the metal shell of the cable tray should be connected to the ground and another end should be connected to the motor enclosure. In the meantime, installing a noise filter can reduce greatly the electromagnetic noise.

4.7.3.2 On-site Wire Arrangement

Power supply cable arrangement: the power supply cable of different control system is connected to the transformer independently. Normally it is 5 core wires, three of which are live wires, one of which is the neutral wire, and one of which is the earth wire. It is strictly prohibitive to the neutral and the earth wire is one wire.

Device categorization: Generally there are different electric devices contained in one control cabinet, such as inverter, electric wave filter, PLC and instrument and so on, which have different ability of emitting and withstanding electromagnetic noise. Therefore, it is necessary to categorize these devices into strong noise device and noise sensitive device.

The same category devices should be installed at the same area, and the distance between different category devices should be more than 20cm.

Wire Arrangement inside the control panel: generally there are signal wire (light current) and power cable (strong current) in one cabinet. For the inverter, the power cables are categorized into incoming cable and outgoing cable. Signal wires can be easily interfered by power cables and thus make the equipment malfunction. Therefore, when wire arrangement, signal wires and power cables should be arranged in different area, it is strictly prohibitive to arrange them in parallel or interlacement at a close distance (less than 20cm), and even to tie them together. If the signal wires have to cross the power cables, they should be arranged in

90 angles. Power incoming cables and outgoing cables should not either be arranged in interlacement or tied together, especially for installing noise filter; otherwise the distributed capacitances of its incoming power cable and outgoing power cable can be coupling each other, consequently making it out of function.

4.7.3.3 Earth Connection

Inverter must be ground connected safely and securely when in operation. As it does not only ensure the safety of equipment and persons, but also is the simplest, most effective and lowest cost solution for EMC problem. Grounding is the top priority.

Grounding has three categories: exclusive pole grounding, common pole grounding, parallel earthwire grounding. Different control system should use exclusive pole grounding, and different devices in the same control system should use common pole grounding, and different devices connected by same power cable should use parallel earthwire grounding.

4.7.3.4 Leakage Current

Leakage current includes line-to-line leakage current and over-ground leakage current. Its

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 25

value depends on distributed capacitances and carrier frequency of the inverter. The over-ground leakage current, which is the current passing through the common earthwire, can flow into not only inverter system but also other equipment through earthwire, making residual current circuit breaker, relay or other devices malfunction. The value of line-to-line leakage current, which means the leakage current passing through distributed capacitors of input wire and output wire, depends on the carrier frequency of inverter, the length of motor cables and their section areas. The higher carrier frequency of inverter, the longer of the motor cable and/or the bigger cable section area, the heavier leakage current will occur.

Countermeasure

Decreasing the carrier frequency can effectively reduce the leakage current, and in the case of motor cable is relatively long (longer than 50m), it is necessary to install AC reactor or sinusoidal wave filter at the output side, and even longer, it is necessary to install one reactor at every certain distance.

4.7.3.5 Noise Filter

Noise filter has a great effect of electromagnetic decoupling, and so even if the optimal operation is fulfilled, it is preferred for customer to install it.

For inverter, noise filter has following categories:

1 Noise filter installed at the input side of inverter

2 Noise insulation for other equipment by means of isolation transformer or mains filter

5.2 Operation Process

5.2.1 Parameter Setting

Three stages of menu respectively are

1. Function code group number (The first-stage menu);

2. Function code label (the second-stage menu);

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 28

3. The set value of function code (the third-stage menu)

Remarks: when working at the third-stage menu, press Button PRG/ESC or Button

DATA/ENT to return to the second-stage menu. The difference between both is: pressing

Button PRG/ESC will save the set parameters into the control panel, and then return to the second-stage menu and also automatically shift to the next function code; pressing Button

DATA/ENT will directly return to the second-stage menu without saving the parameters, and keep staying at the current function code.

For example: change the function code P1.01 setting from 00.00Hz to 01.05Hz

Figure 5-2 Third Stages Menu Operation Process Diagram

Under the third stages menu, if the parameter has no flickering bit, it means this parameter can not be modified. The possible reasons could be:

1) This parameter is unchangeable parameter, such as actual detected parameter, operation records and so on;

2) This parameter is un-modifiable under operating state, but modifiable at stop state

5.2.2 Shortcut Menu

Shortcut menu, in which often used parameters can be put, provides a quick way to view and modify function parameters. At the shortcut menu, a parameter being displayed as

“hP0.11”means it is the function parameter P0.11. Modifying parameters at the shortcut menu has the same effect as doing at general programming state.

Maximum 16 function parameters can be put into the shortcut menu, and in the shortcut menu parameter can be added and deleted when the function code F7-03 is set as 0.

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 29

5.2.2.1 Add shortcut parameter: for instance, to set Function Code P0.00 as shortcut parameter can be done as follows:

Figure 5-3 Example of Adding Parameter into Shortcut Menu

Remarks: If pressing Button QUICK/JOG under the programmable second menu, the display contents will be flickering, asking whether to save this parameter into the shortcut menu. If pressing Button DATA/ENT to confirm, the display contents will stop flickering, and the process is finished; if pressing Button PRG/ESC to cancel, the display contents will stop flickering, and the process is cancelled. If 16 parameters are fully added, “FULLP” will be displayed when trying to save more parameter into the shortcut menu.

5.2.2.2 Shortcut Parameter Operation

Shortcut menu has two stages menus, which are corresponding to the second and third menus of general programming method, and has no corresponding first menu.

Operation can be illustrated by following example:

5.2.2.3 Delete Shortcut Parameters:

Figure 5-5 Example of Deleting Shortcut Parameter

Remarks: if press Button PRG/ESC under the first-stage shortcut menu, the display will be flickering, reminding whether or not to delete. Press Button DATA/ENT to confirm, and the display will stop flickering and jump to next QUICK parameter, ending the delete operation. If press Button QUICK/JOG, the display will stop flickering, canceling the delete operation. If the parameter to delete is the final one, “NULLP” will be displayed after it is deleted, indicating there is no any QUICK parameter.

5.2.3 Fault Reset

If the inverter has fault, it will prompt the related fault information. User can use Button

STOP/RST or terminal function (P5 Group) to conduct fault reset. After fault reset, the inverter is at stand-by state. If user does not reset the inverter when it is at fault state, the inverter will be at operation protection state, and it is unable to run.

5.2.4 Parameter Copy

For details, please refer to the function description of LCD external keyboard

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 32

5.2.5 Motor Parameter Autotune

The procedure of motor parameter autotune is as follows:

At first, choose the keyboard command channel as the operation command channel

(P0.01).

And then input following parameters according to the actual motor parameters:

P2.01: motor rated frequency;

P2.02: motor rated speed;

P2.03: motor rated voltage;

P2.04: motor rated current;

P2.05: motor rated power.

Important note: the motor should be uncoupled with its load; otherwise, the motor parameters obtained through autotune may be not correct. Set P0.17 to be 1, and for the detail process of motor parameter autotune, please refer to the description of Function Code P0.17.

And then press Button RUN on the keyboard panel, the inverter will automatically calculate following parameter of the motor:

P2.06: motor stator resistance;

P2.07: motor rotor resistance;

P2.08: motor stator and rotor inductance;

P2.09: motor stator and rotor mutual inductance;

P2.10: motor no-load current; then motor autotune is finished.

5.2.6 Password Setting:

CHV series inverter provides user’s cryptoguard function. When P7.00 is set to be nonzero, it is the user’s password, and exiting function code edit mode will make the password become effective. If pressing Button PRG/ESC again to try to access the function code edit mode,

“-----”will be displayed, and the operator must input correct user’s password, otherwise will be unable to access it.

If it is necessary to cancel the cryptoguard function, just set P7.00 to zero. User’s cryptoguard has no protection to the parameters in shortcut menu.

5.3 Running State

5.3.1 Power-on Initialization

The system first conducts initialization during the inverter power-on, and LED displays

“-CHV-”. After the initialization is completed, the inverter is on stand-by status.

5.3.2 Stand-by

At stop or running state, parameters at multiple states can be displayed. Whether or not to display this parameter can be chosen through Function Code P7.06 (running parameter) and

P7.07 (stop parameter) according to binary bits, which definitions can be seen in function-code-description of P7.06 and P7.07.

Under stop state, there are total sixteen stop state parameters which can be chosen whether to display or not. They respectively are: set frequency, bus voltage, on-off input status, open collector output status, PID setting, analog input AI1 voltage, analog input AI2 voltage, analog input AI3 voltage, analog input AI4 voltage, high speed pulse input 1 (HDI1), high

P5.00 setting of HDI1 or HDI2 should be set as high speed pulse input, and P5.35 should be set as “Setting Input”.

4 Simple PLC program setting

If this frequency setting mode is chosen, the inverter is operated by simple PLC program.

It is needed to set up the parameters of PA Group “Simple PLC and multi-speed control group” to determine given percentage and given frequency, the coincidence relation between plus minus and rotating direction, and selection of acceleration and deceleration time as well. For details, please refer to description of PA Group functions.

5 Multi-speed operation setting

The inverter is operated in the mode of multi-speed once this frequency setting mode is chosen. It is needed to set up the parameters of P5 Group and PA Group “Simple PLC and multistage speed control group” to determine the coincidence relation between given percentage and given frequency.

6 PID control setting

Selection of this parameter means that the operation mode of inverter is process PID control mode. In this case, it is required to set up P9 Group “PID control group”. The operation frequency of inverter is the frequency value after the PID action. Please refer to the description of P9 Group “PID functions” for the definition of PID giving source, assigned value, feedback source and so on.

Value

Set by model

This function is mainly used to improve the problem of motor operating noise and inverter interference to external and so on.

The advantages of using high carrier frequency: relatively ideal current wave shape, less harmonic current wave and low motor noise

The disadvantages of using high carrier frequency: increased switch loss and inverter temperature rises, affecting inverter output capacity so that it should be operated at derating under high carrier frequency conditions; in the mean time, inverter leakage current and its electromagnetic interference to external are increased.

The situations of using low carrier frequency is on the contrary. Too low carrier frequency can cause operation unstable, torque reduced and even oscillation at low frequency

When inverter is factory released, its carrier frequency has been set properly. Generally the user does not need to modify this parameter.

When the user uses a frequency higher than the default carrier frequency, derating is needed.

Prior to parameters autotune, the motor must be disconnected with its load ensuring the motor at no-load condition, and confirming the motor is at static state.

Prior to parameters autotune, it is a must to correctly input the motor nameplate parameters (P2.01

P2.05), otherwise what is self learned about motor parameters may be not correct.

Prior to parameters autotune, the Acceleration and Deceleration time (P0.11 and P0.12) should be set properly based on the motor inertia, otherwise over current fault may happen during motor parameters autotune.

When the autotune of motor parameters is started by setting P0.17 as 1 and then pushing the button DATA/ENT , LED displays “-TUN-” and flickering, then push the button RUN to begin the procedure of the motor parameters autotune. At this time, “TUN-0”is displayed. After the motor is started, “TUN-1”is shown and “RUN/TUNE” light is flickering. When the autotune of parameters is finished, “-END-”is displayed, and finally back to the stop state interface.

When “-TUN-”is blinking, the process of parameters autotune can exit by pushing the button

The inverter turns off output, and the motor stop process is not controlled by the inverter. It is often applied when the inertia loading is big and there is no requirement on how long to stop.

This mode has the same definition as P1.08 does

This is external failure reset. It has the same function as STOP/RST button on the keyboard. Using this function can perform long-distance failure reset.

The inverter decelerates to stop, but all operation parameters, such as PLC parameters, traverse frequency parameters and PID parameters, are in memory state. After this signal disappears, the inverter restores the operation to the status before pause.

When external fault signal is input into inverter, the inverter reports it and stops.

Above function codes define the relationship between analog input voltage and the setting value that analog input is corresponding to. When the analog input voltage exceeds the range of the set maximum or minimum input, the beyond portion should be calculated with maximum input or minimum input.

When analog input is amperage input, 0mA-20mA is corresponding to 0V-10V.

For different applications, the corresponding nominal value of analog setting 100.0% is different. For details, please refer to each application description.

Following figures shows several settings. Note: AI1 lower limit must be less or equal to AI1 upper limit.

Proportional gain (Kp): determines the adjusting strength of PID adjustor. The bigger the

P, the bigger the adjusting strength is. This parameter being 100 means that when the difference between the PID feedback value and the assigned value is 100%, the adjusting range of PID adjustor to the output frequency command is the maximum frequency (ignore integral action and derivative action).

Integrating time (Ti): determines the speed at which PID adjustor performs integral regulation to the discrepancy between the PID feedback value and the assigned value. The Ti is indicating the period of time that integral controller (ignore proportional action and derivative action), when the discrepancy between the PID feedback value and the assigned value is

100%, continuously regulates to make the regulating amount to reach the maximum frequency

(P0.07). The shorter the integrating time, the stronger the adjusting strength is.

Differential time (Td): determines the controlling strength at which PID adjustor performs adjustment to the variance ratio of discrepancy between the PID feedback value and the assigned value. The Td is indicating the period of time within which if the feedback value is changed 100%, the regulating amount of integral controller is the maximum frequency (P0.07)

(ignore proportional action and integral action). The longer the Td, the bigger the controlling strength is.

PID is the most popularly used control mode in process control, with each part playing different role. Following simply introduces the operational principle and the controlling method:

Proportion control (P): when there is discrepancy between feedback and the assignment, output the regulating amount in proportion to the discrepancy. If the discrepancy is constant, the regulating amount keeps constant. Proportion control can response quickly to the feedback variation, but only using proportion control is unable to perform noncorresponding control. The bigger the proportional gain, the faster the system regulating speed, but being too big may cause oscillation. The control method is first to set a long integrating time and a zero differential time, and then run the system only by using proportion control. Change the assigned value, and watch the stable discrepancy (steady-state error) of feedback signal and assigned value. If the steady-state error is at the varying direction of assigned value (for instance, increase the assigned value, the feedback value after the system is steady is always less than the assigned value), continue to increase the proportional gain, otherwise decrease it.

Repeat the above until the steady-state error is relatively small (it is very difficult to do no steady-state error).

Integral time (I): when there is a discrepancy between the feedback and assignment, continuously accumulate the output regulation amount. If the discrepancy still exists, continue to increase the regulation amount until there is no discrepancy. Integral controller can effectively eliminate the steady-state error. Integral controller being too strong can cause repeated overshooting, system unstable and up till oscillating. The characteristic of oscillation caused by too strong integral action is that the feedback signal is swinging up and down around the assigned value, and the amplitude of swing increases gradually till the oscillation

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 74

happens. Normally the integral time is adjusted from big to small, gradually regulate the integral time, and watch the effect, until the system stable speed meets requirements.

Differential time (D): when the discrepancy between feedback and assignment varies, output a regulation amount in proportion to the variance ratio of discrepancy. The regulation amount is related to the direction and magnitude of discrepancy variation, but irrelevant to the direction and value of the discrepancy itself. The differential control action is to perform the control according to the varying trend when the feedback signal variation happens, and thereby to restrain the feedback signal variation. It should be caution to use differential controller as the differential control have a trend to magnify the system interference, especially the high varying frequency interference.

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 79

1: general motor (with low speed compensation). As general motor has a poor heat emission at low speed, the relevant electronic thermal protection should be regulated properly.

The low speed compensation characteristic here mentioned is to switch down the overloading protection threshold for the motor with an operation frequency lower than 30 Hz.

2: Variable frequency motor (without low speed compensation). As the heat emission of special variable frequency motor is not affected by speed, it is not required to regulate the protection value for low speed operation.

If the instant power-down drop rate is set to be 0, the instant power-down restart function is invalid.

Instant power-down frequency drop point: it is indicting when the bus voltage, after the power network is down and drops to the instant power-down frequency drop point, the inverter starts to decrease the operation frequency based on the instant power-down frequency drop rate, enabling the motor to generate electricity which is fed back to keep the bus voltage, and thus ensuring the inverter is operating normally till inverter power is on again.

Important: Adjusting these two parameters properly can magnificently achieve the power network switching instead of causing inverter protection and thus causing production shutdown.

During the inverter deceleration, the load inertia may cause the actual motor speed drop rate lower than the output frequency drop rate, and thereby the motor generates electricity and feeds it back to the inverter, causing the inverter bus voltage going up and even bus over-voltage breakdown which then can cause inverter tripping if no provision is made.

Over-voltage stall protection function is to detect the bus voltage and compare it with the stall over-voltage point defined by Pb.10 (relative to the standard bus voltage). If it exceeds the over-voltage stall point, inverter output frequency stop going down, and when the next bus

During inverter acceleration, the load is so big that the actual motor speed increase rate is lower than the output frequency increase rate, causing the ACCEL over-current breakdown which then could cause inverter tripping if no provision is made.

Over-current stall protection function is to detect the output current and compare it with the stall over-current point defined by PB.12. If it exceeds the stall over-current point, the inverter output frequency decreases at the over-current frequency drop rate (Pb.13), and when the next output current detected is lower than the over-current stall point, the inverter continues to accelerate, as shown by following figure:

Inverter may have following failures or malfunctions during operation, please refer to following solutions to do simple analysis.

No display after power on

Use multimeter to examine whether or not the voltage of power supply is the same as the inverter rated voltage. If the power supply has problem, examine it and eliminate it.

Examine whether the three-phase rectification bridge is in good condition or not. If the

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 85

rectification bridge is burst out, ask for service.

Check the CHARGE light. If the light is not bright, generally the failure is at the rectification bridge or at the buffer resistor. If the light is bright, the failure may be at the switching power supply. Ask for service.

Power supply air-break switch trip-off when power on:

Examine whether or not input power supply is grounded or short circuit failure, and eliminate the problem.

Examine whether the rectification bridge has been burnt or not. If it is damaged, ask for service.

Motor doesn t move while inverter is put in operation

Inspect if there is balanced three-phase output among U,V,W. If there is, the motor circuit or itself is damaged, or the motor is mechanically locked. Please clear it off.

There is output but uneven among the three phases, the inverter drive board or the output module is supposed to be damaged, ask for service.

If there is no output voltage, it may be damage of inverter drive board or the output module, ask for service.

Inverter displays in normal condition, but the power supply air switch trips off after put in operation:

Examine if there is short circuit of phases between output modules. If there is, ask for service.

Examine if there is short circuit or ground between motor wires. If there is, eliminate it.

If the trip-off happens occasionally and the distance between motor and inverter is far, it should be considered to add output AC reactor.

Appendix

CHV series inverter function parameters, which are grouped by functions, have P0-PF total 16 groups among which the PF is the expanded function parameters that user can visit if the inverter has been installed with extension card. Each function group includes a number of function codes, which adopts three-stage menu, for instance, “P8.08”means the 8 th

function code of P8 th

function.

For the convenience of setting function code by using operation panel, the function group number is corresponding to Stage 1 menu, the function code is corresponding to Stage 2 menu and the function code parameter is corresponding to Stage 3 menu.

1. The column of function table is described as follows:

The 1 st

column “Function Code” is the function parameter group and parameter code.

The 2 nd

column “Name” is the complete name of the function parameter.

The 4 th

column “Setting Range” is the effective setting value range of the function parameter, shown on the operation panel LCD (liquid crystal display).

The 5 th

“Default” is the original factory setting value of this function parameter.

The 6 th

“Modification” is the modification performance of the function parameter (i.e. whether or not it is permitted to modify and the modification conditions), explained as follows,

“ ”: indicates that the setting value of this parameter can be modified when the inverter is either in stop or operating status;

“ ”: means that the setting value of this parameter cannot be modified when the inverter is in operating status;

(Inverter has done the automatic detection restriction to the modification performance of each parameter, helping user to prevent mis-modification.)

The 7 th

column “LCD Display” is the brief description of function parameter name on the operation panel LCD (liquid crystal display);

The 8 th

column “Serial No.” is the serial number of this function code in the whole function codes, and also is the communication register address.

2. “Parameter Digital System” is the decimal system. If parameters are expressed in hexadecimal system, the value at each digit is independent when the parameter is edited, and the numeric area of some digits can be hexadecimal (0-F).

3. “LCD Display Description” is only valid when using external LCD operation panel.

4. “Default” indicates the value of the function code after it is refreshed while doing the manipulation of restoring the factory parameters; but the actually detected parameters or record values cannot be refreshed.

5. In order to effectively protect the parameters, the inverter provides the cryptoguard for the function code. After the user’s password is set up (i.e. user’s password P7.00 parameter is not

0), when the user press PRG/ESC button to enter function code edit status, the system first

SHENZHEN INVT ELECTRIC CO., LTD. CHV160 Operation Manual 88

Function

Code enters the user’s password verification status, displaying “-----“, and the operator must input correctly the user’s password, otherwise it is impossible to enter. For the parameters that are factory set up, can enter only if a correct factory password is input as required. (Here remind user DO NOT try to modify the factory parameters, and if the parameters are not set up properly, it can cause inverter malfunction or even damage.) At the state that the cryptoguard is not locked, the user’s password can be modified at any time, and the one finally input will be the user’s password. If P7.00 is set as 0, the user’s password can be cancelled; when the power is on, if P7.00 is not 0, parameters are protected by password. When serial communication is used to modify the function parameters, the function of user’s password also fellows above rule.
