1

Motor insulation inspection

2

Motor thermal protection

Explanation

Please perform motor insulation inspection for the first time use,re-use after leaving unused for a long time as well as regular check, in order to prevent damage to the inverter because of the motor's winding insulation failure. Wiring between motor and inverter shall be disconnected, it is recommended that the 500V voltage type megger should be adopted and insulation resistance shall be not less than 5MΩ.

If the rated capacity of the selected motor does not match the inverter, especially when the inverter rated power is greater than the motor rated power, be sure to adjust the motor protection parameter values inside inverter or install thermal relay in the front of motor for motor

Run over power frequency

Vibrations of mechanical device

Motor heat and noise

Contactor or switch used in the inverter input/output terminals

Use other than the ratedvoltage protection.

The inverter output frequency rang is 0Hz to 3200Hz(Max.vector control only supports 300Hz). If the user is required to run at 50Hz or more, please consider the endurance of your mechanical devices.

Inverter output frequency may be encountered mechanical resonance point of the load device, you can set jump frequency parameter inside inverter to avoid the case.

The inverter output voltage is PWM wave that contains a certain amount of harmonics, so the temperature rise, noise and vibration of motor show a slight higher than frequency power frequency operation.

The inverter output is PWM wave, if the piezoresistor for lightning protection or the capacitor for improving power factor is installed in the output side, which easily cause the inverter instantaneous overcurrent or even cause damage to the inverter. Please do not use.

If contactor is installed between power supply and inverter, the contactor is not allowed to start/stop the inverter. Necessarily need to use the contactor to control the inverter start/stop, the interval should not be less than one hour. Frequent charging and discharging may reduce the service life of the inverter capacitor. If the contactor or switch is equipped between output terminals and motor, the inverter should be turned on/off without output status,otherwise which easily lead to damage to the inverter module.

PI series inverter is not suitable for use beyond the allowable operating voltage described in this manual, which easily cause damage to the parts inside inverter. If necessary, please use the corresponding transformer to change voltage.

9

Never change 3phase input to 2phase input

Never change PI series 3-phase inverter to 2-phase one for application.

Otherwise it will lead to malfunction or damage to the inverter.

Lightning surge protection

High altitude and derating application

12 Special use

Precautions for scrap disposal of the inverter

14 Adaptive motor

The series inverter is equipped with lightning overcurrent protection device, so it has the ability of self-protection to lightning induction.

For the area where lightning is frequent, user should also install the extra protection in the front of the inverter.

When the inverter is used in areas over 1000m altitude, it is required to reduce frequency because the thin air will decrease the cooling effect of inverter. Please consult our technician for details on the application.

If the user need to use methods other than the suggested wiring diagram provided in this manual, such as common DC bus, please consult our technician.

When electrolytic capacitors on the main circuit and printed circuit board as well as plastic parts are burned, it may produce toxic gases.Please disposing as industrial waste.

1) Standard adaptive motor shall be four-pole asynchronous squirrelcage induction motor . Apart from the said motors, please select the inverter according to the motor rated current.

2)The cooling fan and the rotor shaft for non-inverter motor are coaxially connected, the fan cooling effect is reduced when the rotational speed is reduced, therefore, when the motor works in overheating occasions, a strong exhaust fan should be retrofitted or replace non-inverter motor with the inverter motor.

3) The inverter has built-in the adaptive motor standard parameters, according to the actual situation, please identify motor parameters or accordingly modify the default values to try to meet the actual value,

Chapter 1 Inspection and safety precautions

15 Others otherwise it will operation affect and protection performance.

4)When short-circuit of cable or motor internal will activate the inverter alarm, even bombing. Therefore, firstly perform insulation short-circuit test for the initial installation of the motor and cable,routine maintenance often also need to perform such test. Note that the parts to be tested and the inverter shall be disconnected completely when testing.

1) We need to fix cover and lock before power on, so as to avoid the harm to personal safety that is caused by internal injuries of bad capacitors and other components.

2)Do not touch internal circuit board and any parts after powering off and within five minutes after keyboard indicator lamp goes out,you must use the instrument to confirm that internal capacitor has been discharged fully, otherwise there is a danger of electric shock.

3)Body static electricity will seriously damage the internal MOS field-effect transistors, etc., if there are not anti-static measures, do not touch the printed circuit board and IGBT internal device with hand, otherwise it may cause a malfunction.

4) The ground terminal of the inverter(E or ) shall be earthed firmly according to the provisions of the National Electrical Safety and other relevant standards. Do not shut down(Power off) by pulling switch, and only cut off the power until the motor stopping operation.

5)It is required to add the optional input filter attachment so as to meet CE standards.

4-5.Wiring Precautions

Danger

Make sure that the power switch is in the OFF state before wiring operation, or electrical shock may occur!

21

Chapter 4 Installation and commissioning

Wiring must be performed by a professional trained personnel, or this may cause damage to the equipment and personal injury!

Must be grounded firmly, otherwise there is a danger of electric shock or fire hazard !

Note

Make sure that the input power is consistent with the rated value of inverter, otherwise which may cause damage to the inverter!

Make sure that the motor matches the inverter, otherwise which may cause damage to the motor or activate the inverter protection!

Do not connect power supply to U, V, W terminals, otherwise which may cause damage to the inverter!

Do not directly connect braking resistor to DC bus (P), (+) terminals, otherwise which may cause a fire!

※ The U,V,W output end of inverter can not install phase advancing capacitor or RC absorbing device. The inverter input power must be cut off when replacing the motor

※ Do not let metal chips or wire ends into inside the inverter when wiring, otherwise which may cause malfunction to the inverter.

※ Disconnect motor or switch power-frequency power supply only when the inverter stops output

In order to minimize the effects of electromagnetic interference, it is recommended that a surge absorption device shall be installed additionally when electromagnetic contactor and relay is closer from the inverter.

※ External control lines of inverter shall adopt isolation device or shielded wire.

※ In addition to shielding, the wiring of input command signal should also be aligned separately, it is best to stay away from the main circuit wiring.

※

If the carrier frequency is less than 3KHz, the maximum distance between the inverter and the motor should be within 50 meters; if the carrier frequency is greater than 4KHz, the distance should be reduced appropriately, it is best to lay the wiring inside metal tube.

※ When the inverter is additionally equipped with peripherals (Filter, reactor, etc.), firstly measure its insulation resistance to ground by using 1000 volt megger, so as to ensure the measured value is no less than 4 megohms.

※ When the inverter need to be started frequently, do not directly turn power off, only the control terminal or keyboard or RS485 operation command can be used to control the start/stop operation, in order to avoid damage to the rectifier bridge.

※ To prevent the occurrence of an accident, the ground terminal( )must be earthed firmly

(grounding impedance should be less than 10 ohms), otherwise the leakage current will occur.

※ The specifications on wires used by the main circuit wiring shall comply with the relevant provisions of the National Electrical Code.

※ The motor's capacity should be equal to or less than the inverter's capacity.

Description

The terminal for not use can be set to "no function" to prevent

Accidental operation.

1 Forward run (FWD)

External terminals are used to control the FWD/REV run mode of inverter.

2 Reverse run (REV)

This terminal is used to determine the inverter's three-wire

Terminal DOWN

Free stop

Frequency is referenced by external terminal. Adjust up/down the set frequency when the digital setting is selected as the frequency source.

The inverter output is blocked, at the time, the parking process of motor is not controlled by the inverter. This way is same as the principle of free stop described in F3.07.

Fault reset (RESET)

Run pausing

The function make use of terminal for fault reset. It has same

Function with RESET key on the keyboard. This function can be used to realize remote fault reset.

The inverter slows down and stops, but all operating parameters are memorized. Such as PLC parameters, wobbulate frequency parameters, and PID parameters. This terminal signal disappears, the inverter reverts to the previous state of running before parking.

When the signal is sent to the inverter, the inverter reports fault Err.15, and performs troubleshooting according to fault protection action (for details, please refer to the function code

F8.17).

The selection of 4 ac/deceleration times can be achieved through the 4 states of the two terminals. For details, see

Used to switch between different frequency sources.

According to frequency source selection function code

(F0.07) settings, the terminal is used to switch between two frequency sources.

When the frequency reference is the digital frequency, this terminal is used to clear the changed frequency value by terminal UP/DOWN or keyboard UP/DOWN, so that the reference frequency can recover to the set value of F0.01.

When the command source is set to the terminal control

(F0.11 =1), the terminal can be used to switch between terminal control and keyboard control.

PID integral pause

When the command source is set to the communication control (F0.11 = 2), the terminal can be used to switch between communication control and keyboard control.

Ensure the inverter is free from external signals affect (except for shutdown command), maintain current output frequency.

PID is temporarily disabled, the inverter maintains current

Output frequency, no longer performs PID adjustment of frequency source.

If the terminal is active, the inverter switches directly to DC

Braking status

When the signal of external fault normally closed input is

Inputted into the inverter, the inverter will report fault Err.15 and shutdown.

If the function is set to be valid, when the frequency changes, the inverter does not respond to frequency changes until the terminal state is invalid.

If the terminal is valid, PID action direction opposites to the

Direction set by E2.03

Under keyboard control mode, the terminal can be used to stop the inverter, same as STOP key on the keyboard.

Used to switch between terminal control and communication

Control. If the command source is selected as terminal control, the system will be switched to the communication control mode when the terminal is active; vice versa.

When the terminal is active, the PID integral adjustment function is paused, but the proportion and differential adjustments of PID are still valid.

Switch between frequency source master setting and preset frequency

Switch between frequency source auxiliary setting and

When the terminal is active, the frequency source A is replaced by the preset frequency (F0.01)

When the terminal is active, the frequency source B is replaced with the preset frequency (F0.01)

When DI terminal (E2.19 = 1) is used to switch PID parameters, if the terminal is invalid, PID parameters use

E2.13 to E2.15; if the terminal is valid, PID parameters use

E2.16 to E2.18

When custom fault 1 and custom fault 2 are active, the inverter respectively alarms fault Err.27 and fault Err.28, and deals with them according to the mode selected by the fault protection action F8.19.

If the terminal is valid, the inverter will park at the fastest speed,and the current maintains at the set upper limit during the parking process. This function is used to meet the requirements that the inverter needs to stop as soon as possible when the system is in a emergency state.

In any control mode (Keyboard control, terminal control, communication control), the terminal can be used to decelerate the inverter until stop, at the time the deceleration time is fixed for deceleration time 4.

6-2.EMC (Electromagnetic compatibility)

6-2-1.Definition

Electromagnetic compatibility refers to the ability that the electric equipment runs in an electromagnetic interference environment and implements its function stably without interferences on the electromagnetic environment.

6-2-2.EMC standard

In accordance with the requirements of the Chinese national standard GB 12668.3-2012/IEC

61800-3:2004, the inverter must comply with the requirements of electromagnetic interference and anti- electromagnetic interference.

Our existing products adopt the latest international standards: IEC/EN61800-3: 2004

(Adjustable speed electrical Power drive systems Part 3: EMC requirements and specific test methods), which is equivalent to the Chinese national standards GB 12668.3-2012/IEC 61800-

3:2004. EC/EN61800-3 assesses the inverter in terms of electromagnetic interference and antielectronic interference. Electromagnetic interference mainly tests the radiation interference, conduction interference and harmonics interference on the inverter (necessary for civil inverter).

Anti-electromagnetic interference mainly tests the conduction immunity, radiation immunity, surge immunity, EFTB(Electrical Fast Transient Burs) immunity, ESD immunity and power low frequency end immunity (the specific test items includes: 1. Immunity tests of input voltage sag, interrupt and change; 2.Commutation notch immunity; 3. harmonic input immunity ; 4. input frequency change; 5. input voltage unbalance; 6. input voltage fluctuation). The tests shall be conducted strictly in accordance with the above requirements of IEC/EN61800-3, and our products are installed and used according to the guideline of the Section 6-3 and can provide good electromagnetic compatibility in general industry environment.

6-3.EMC directive

6-3-1.Harmonic effect

The higher harmonics of power supply may damage the inverter. Thus, at some places where

51

Chapter 6 Troubleshooting

the quality of power system is relatively poor, it is recommended to install AC input reactor.

6-3-2.Electromagnetic interference and installation precautions

There are two kinds of electromagnetic interference, one is the interference from electromagnetic noise in the surrounding environment to the inverter, and the other is the interference from the inverter to the surrounding equipment.

Installation Precautions:

1)The earth wires of the Inverter and other electric products ca shall be well grounded;

2)The power cables of the inverter power input and output and the cable of weak current signal (e.g. control line) shall not be arranged in parallel but in vertical if possible.

3) It is recommended that the output power cables of the inverter shall use shield cables or steel pipe shielded cables and that the shielding layer shall be grounded reliably, the lead cables of the equipment suffering interferences shall use twisted-pair shielded control cables, and the shielding layer shall be grounded reliably.

4)When the length of motor cable is longer than 50 meters, it needs to install output filter or reactor.

6-3-3.Remedies for the interference from the surrounding electromagnetic equipment to the inverter

Generally the electromagnetic interference on the inverter is generated by plenty of relays, contactors and electromagnetic brakes installed near the inverter. When the inverter has error action due to the interference, the following measures is recommended:

1) Install surge suppressor on the devices generating interference;

2) Install filter at the input end of the inverter, please refer to Section 6.3.6 for the specific operations.

3) The lead cables of the control signal cable of the inverter and the detection line shall use the shielded cable and the shielding layer shall be grounded reliably.

6-3-4.Remedies for the interference from the inverter to the surrounding electromagnetic equipment

These noise interference are classified into two types: one is the radiation interference of the inverter, and the other is the conduction interference of the inverter. These two types of interference cause that the surrounding electric equipment suffer from the affect of electromagnetic or electrostatic induction. Further, the surrounding equipment produces error action. For different interference, please refer to the following remedies:

1) Generally the meters, receivers and sensors for measuring and testing have more weak signals. If they are placed nearby the inverter or together with the inverter in the same control cabinet, they easily suffer from interference and thus generate error actions. It is recommended to handle with the following methods: away from the interference source as far as possible; do not arrange the signal cables with the power cables in parallel and never bind them together; both the signal cables and power cables shall use shielded cables and shall be well grounded; install ferrite magnetic ring (with suppressing frequency of 30 to 1, 000MHz) at the output side of the inverter and wind it 2 to 3 turns; install EMC output filter in more severe conditions.

2) When the interfered equipment and the inverter use the same power supply, it may cause conduction interference. If the above methods cannot remove the interference, it shall install EMC filter between the inverter and the power supply (refer to Section 6.3.6 for the selection operation);

3) The surrounding equipment shall be separately grounded, which can avoid the interference caused by the leakage current of the inverter's grounding wire when common grounding mode is adopted.

6-3-5.Remedies for leakage current

There are two forms of leakage current when using the inverter. One is leakage current to the earth, and the other is leakage current between the cables.

1) Factors of affecting leakage current to the earth and its solutions:

52

Chapter 6 Troubleshooting

There are the distributed capacitance between the lead cables and the earth. The larger the distributed capacitance, the larger the leakage current; the distributed capacitance can be reduced by effectively reducing the distance between the inverter and the motor. The higher the carrier frequency, the larger the leakage current. The leakage current can be reduced by reducing the carrier frequency. However, the carrier frequency reduced may result in the increase of motor noise. Please note that additional installation of reactor is also an effective method to solve leakage current problem.

The leakage current may increase with the increase of circuit current. Therefore, when the motor power is higher, the corresponding leakage current will be higher too.

2) Factors of producing leakage current between the cables and its solutions:

There is the distributed capacitance between the output cables of the inverter. If the current passing lines has higher harmonic, it may cause resonance and thus result in leakage current. If the thermal relay is used, it may generate error action.

The solution is to reduce the carrier frequency or install output reactor. It is recommended that the thermal relay shall not be installed in the front of the motor when using the inverter, and that electronic over current protection function of the inverter shall be used instead.

6-3-6.Precautions on installing EMC input filter at the input end of power supply

1) Note: when using the inverter, please follow its rated values strictly. Since the filter belongs to Classification I electric appliances, the metal enclosure of the filter and the metal ground of the installing cabinet shall be well earthed in a large area, and have good conduction continuity, otherwise there may be danger of electric shock and the EMC effect may be greatly affected.

Through the EMC test, it is found that the filter ground end and the PE end of the inverter must be connected to the same public earth end, otherwise the EMC effect may be greatly affected.

2) The filter shall be installed at a place close to the input end of the power supply as much as possible.

8-3.Storage

The following actions must be taken if the inverter is not put into use immediately(temporary or long-term storage) after purchasing:

※ It should be store at a well-ventilated site without damp, dust or metal dust, and the ambient temperature complies with the range stipulated by standard specification

※ Voltage withstand test can not be arbitrarily implemented, it will reduce the life of inverter.

Insulation test can be made with the 500-volt megger before using, the insulation resistance shall not be less than 4MΩ.

If the frequency inverter hasn’t been used for a long time, before using it please rebuilt the DC bus capacitor according the instruction. The storage time is counted from delivery.

Time Operation instruction

Less than 1 year

Between 1~2 years

No need to recharge

Before the first time to use, the frequency inverter must be recharged for one hour

Between 2~3years

Use adjustable power to charge the frequency inverter:

--25% rated power 30 minutes,

-- 50% rated power 30minutes,

-- 75% rated power 30minutes,

--Last 100% rated power 30minutes

More than 3 years

Use adjustable power to charge the frequency inverter:

--25% rated power 2hours,

--50% rated power 2 hours,

-- 75% rated power 2hours,

-- Last 100% rated power 2hours

Instruction of using adjustable power to charge the frequency inverter:

The adjustable power is decided by the frequency inverter input power, for the single phase/3 phase 220v frequency inverter, we uase 220v AC/2A Regulator. Both single phase and three phase frequency inverter can be charged by single phase Power Surge(L+ connect R,N connects T)

Because it is the same rectifier,so al l the DC bus capacitor will be charged at the same time.

You should make sure the voltage(380v) of high voltage frequency inverter, because when the capacitor being charged it almost doesn’t need any current, so small capacitor is enough(2A)

The instruction of using resisitor( incandescent lights) to charge frequency inverters:

When charge the DC bus capacitor of drive system by connecting power directly, then the time should not be less than 60 minutes. The operation should be carried on under the condition of normal temperature and without load, and moreover ,should be added resistor in the power supply cycle.

380V drive system: use 1K/100W resistor. When the power is less than 380v, 100w incandescent lights is also suitable. When using incandescent lights, the lights will extinct or become very weak.

※ If a general instrument is used to measure current, imbalance will exists for the current at theinput terminal. generally, the deviation is not more than 10%, that is normal. If the deviationexceeds 30%, please inform the original manufacturer to replace rectifier bridge, or check ifthe deviation of three-phase input voltage is above 5V or not.

※ If a general multi-meter is used to measure three-phase output voltage, the reading is not accurate due to the interference of carrier frequency and it is only for reference.

1.Power cables

The dimension of input power cable and motor cable should meet the local provision:

Input power cable and motor cable should bear the related load current

The maximum rated temperature margin conditions of the motor cable should not be sustained below 70 degrees .

Conductivity of the PE conductor and phase conductor capacity are the same(same crosssectional area)

About EMC requirements, see "EMC Guidance Content"

To meet the CE EMC requirements, a symmetrical shielded motor cable must be used (see figure below).

For input cables can use four-core cable, but still recommended to use shielded symmetrical cable. Compared to a four-core cable, shielded symmetrical cables can not only reduce the loss and cost of the current flowing through the motor cable, but also can reduce the electromagnetic radiation.

Symmetrical shielded motor cables conductor conductor PE

Four-core cable conductor PE

Insulation Insulation Insulation

Note: If conductivity of the cable shield can not meet the requirements, you must use a separate PE conductor.

To play a protective role of conductor, when the shield wire and phase conductors using the same material, the cross-sectional area of the shield wire and phase conductors cross-sectional area must be the same, aims to reduce grounding resistance, impedance continuity better

To effectively suppress RFI transmission and conduction, the shield conductivity must be at least 1/10 of the phase conductor conductivity. For copper or aluminum shield, this requirement is very easy to meet. Minimum requirements for the drive motor cable as shown below. Cable comprising a layer of copper spiral. Shield tight as possible, that the more tightly the more we can effectively suppress radiated electromagnetic interference.

2.Control cable

All analog control cables and cables for the frequency input must be shielded. Analog signal cable double-shielded twisted pair cable as shown in Figure 1. Each signal uses one pair individually shielded twisted pair cable pair. Do not use the different analog signal with a ground wire.

Chapter 9 Optional part

single-shielded or unshielded twisted pair, as shown in Figure 2, however, the frequency of the signal, it can only use a shielded cable.

Relay cable need to use cables with metal braid shield.

Need to use a network cable to connect the keyboard, for electromagnetic environment is more complex place, it is recommended to use shielded cable.

Note: analog and digital signals using different cables routed separately.

3.Interference counte

Connect noise filter on the output side of inverter can reduce inductive interference and radio interference .

→Inductive interference :The electromagnetic induction makes the signal line noise when upload signal ,and then cause the control equipment malfunction.

→ Wireless interference :The high-frequency electromagnet wave emitted by the inverter and cables will interfere with the nearby wireless device and make it noise when receiving signal.

Appendix I RS485 Communication protocol

I-1 Communication protocol

I-1-1 Communication content

This serial communication protocol defines the transmission information and use format in the series communication Including: master polling( or broadcast) format; master encoding method, and contents including: function code of action, transferring data and error checking. The response of slave also adopts the same structure, and contents including: action confirmation, returning the data and error checking etc. If slave takes place the error while it is receiving information or cannot finish the action demanded by master, it will send one fault signal to master as a response.

Application Method

The inverter will be connected into a “Single-master Multi-slave” PC/PLC control network with RS485 bus.

Bus structure

(1)Transmission mode

Asynchronous series and half-duplex transmission mode. For master and slave, only one of them can send the data and the other only receives the data at the same time. In the series asynchronous communication, the data is sent out frame by frame in the form of message

Topological structure

Single-master and multi-slave system. The setting range of slave address is 0 to 247, and 0 refers to broadcast communication address. The address of slave for network must be exclusive

Diagram I-3 is the single inverter and PC set up MODBUS field wiring diagram. Because computers are generally not with RS485 interface, the computer must be built-in RS232 interface or USB interface through the converter to convert to RS485. Connect the T + of converter with 485

+ terminal of the inverter, Connect the T- of converter with 485- terminal of inverter. We recommended to use a shielded twisted pair. When adopting the RS232-485 converter, RS232 interface connected with RS232-RS485 RS232 interface, the cable should be as short as possible,15meters at the longest, we recommend to plug the RS232-RS485 with computer in pair directly. Similarly, when using the USB-RS485 converter, cable should be as short as possible.

When the line is connected, connect the right port of the host computer on the computer to

(RS232-RS485 converter port, such as COM1), and set the basic parameters and the baud rate and data bit parity and so on consistent with the inverter.

I-1-3 Protocol description

PI500 series inverter communication protocol is a asynchronous serial master-slave communication protocol, in the network, only one equipment(master) can build a protocol (known as “Inquiry/Command”). Other equipment(slave) only can response the "Inquiry/Command"of master by providing data or perform the corresponding action according to the

"Inquiry/Command"of master. Here, the master refers to a Personnel Computer(PC), an industrial control device or a programmable logic controller (PLC), etc. and the slave refers to PI500 inverter.

Master can communicate with individUal slave, also send broadcasting information to all the lower slaves. For the single "Inquiry/Command"of master, slave will return a signal(that is a response) to master; for the broadcasting information sent by master, slave does not need to feedback a response to master.

Communication data structure PI500 series inverter's Modbus protocol communication data format is as follows: in RTU mode, messages are sent at a silent interval of at least 3.5 characters.

There are diverse character intervals under network baud rate, which is easiest implemented. The first field transmitted is the device address.

The allowable characters for transmitting are hexadecimal 0 ... 9, A ... F. The networked

70

Appendix I

devices continuously monitor network bus, including during the silent intervals. When the first field (the address field) is received, each device decodes it to find out if it is sent to their own.

Following the last transmitted character, a silent interval of at least 3.5 characters marks the end of the message. A new message can begin after this silent interval.

The entire message frame must be transmitted as a continuous stream. If a silent interval of more than 1.5 characters occurs before completion of the frame, the receiving device will flushes the incomplete message and assumes that the next byte will be the address field of a new message.

Similarly, if a new message begins earlier than the interval of 3.5 characters following a previous message, the receiving device will consider it as a continuation of the previous message. This will result in an error, because the value in the final CRC field is not right.

I-2 Check mode:

Check mode - CRC mode: CRC (Cyclical Redundancy Check) adopts RTU frame format, the

Message includes an error-checking field that is based on CRC method. The CRC field checks the whole content of message. The CRC field has two bytes containing a 16-bit binary value. The

CRC value calculated by the transmitting device will be added into to the message. The receiving device recalculates the value of the received CRC, and compares the calculated value to the Actual value of the received CRC field, if the two values are not equal, then there is an error in the transmission.

The CRC firstly stores 0xffff and then calls for a process to deal with the successive eight-bit

Bytes in message and the value of the current register. Only the 8-bit data in each character is valid to the CRC, the start bit and stop bit, and parity bit are invalid.

During generation of the CRC, each eight-bit character is exclusive OR(XOR) with the register

Contents separately, the result moves to the direction of least significant bit(LSB), and the most significant bit(MSB) is filled with 0. LSB will be picked up for detection, if LSB is 1, the register will be XOR with the preset value separately, if LSB is 0, then no XOR takes place. The whole process is repeated eight times. After the last bit (eighth) is completed, the next eight-bit byte will be XOR with the register's current value separately again. The final value of the register is the CRC value that all

The bytes of the message have been applied.

When the CRC is appended to the message, the low byte is appended firstly, followed by the high byte. CRC simple functions is as follows:

Unsigned int crc_chk_value(unsigned char *data_value,unsigned char length)

{ unsigned int crc_value=0xFFFF; int i; while(length--)

{ crc_value^=*data_value++;

72

} c r c _ v a l u e = ( c r c _ v a l u e > > 1 )^0xa001; else

{ crc_value=crc_value>>1;

} return(crc_value);

Some parameters can not be changed during operation, but some parameters can not be changed regardless of the inverter is in what state.When changing the function code parameters, please pay attention to the scope, units, and relative instructions on the parameter.

Besides, due to EEPROM is frequently stored, it will redUce the life of EEPROM, therefore under the communication mode some function code do not need to be stored and you just change the RAM value.

If F group parameters need to achieve the function, as long as change high order F of the function code address to 0. If E group parameters need to achieve the function, as long as change high order A of the function code address to 4. The corresponding function code addresses are indicated below: high byte: 00 to 0F(F group), 40 to 4F (E group), 50 to 5F(B group),60 to

Inverter A pump begins running, the frequency is bigger than F0.21; and feedback pressure is less than the set pressure (E8.07), and lasts until the delay time set by E8.08, when the pump condition is satisfied, the pump is added. The system is switched according to the sequence principle of frequency conversion A pump and frequency conversion pump plus one:

A Pump running normally→add pump when pressure is insufficient→Frequency conversion shutdown operation of pump A→Delay time after frequency inverter frequency switch to power frequency(E8.09)→A pump

running

at power frequency→frequency inverter frequency (E8.10)

→B pump frequency inverter running→add pump when pressure is insufficient→Frequency conversion shutdown operation of pump B→Delay time after frequency inverter frequency switch to power frequency(E8.09)→B pump running at power frequency→frequency inverter frequency

(E8.10) →C pump running at power frequency→add pump when pressure is insufficient →

Frequency conversion shutdown operation of pump C→Delay time after frequency inverter frequency switch to power frequency(E8.09)→C pump rnning at power frequency→frequency inverter frequency(E8.10)→D pump frequency inverter running.

Pump reduction instructions:

If the A, B and C pumps are power frequency, the D pump is frequency inverter.

When the frequency inverter pump runs to E8.13 pump reduction frequency and the feedback pressure E8.12, after continuing the delay time of E8.14 pump reduction, the pump reduction is started. The system starts in sequence, starts first according to the normal principle, stops first, stops the power frequency A pump ,power frequency B ,pump power frequency C pump.
