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 protection.
The inverter output frequency rang is 0Hz to
3200Hz(Maz.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.

Chapter1.Inspection and Safety Precautions 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 piezo-resistor for lightning protection or the capacitor for improving power factor is installed in the output side, which easily cause the inverter instantaneous over-current 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.
Never change PI series 3-phase inverter to 2-phase one for application. Otherwise it will lead to malfunction or damage to the inverter.
The series inverter is equipped with lightning over-current 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 squirrel-cage induction motor or permanent magnet synchronous motor. Apart from the said motors, please select the inverter according to the motor rated current.

1) The function code can not be modified itself, eg: actual detecting parameters, running record parameters.
2) The function code can not be modified in the running status. It must be modified in the stop status.
3-4-2.The way to read parameters in various status
In stop or run status, operate shift key
SHIFT
to display a variety of status parameters respectively. Parameter display selection depends on function code F6.01 (run parameter 1), F6.02 (run parameter 2) and F6.03 (stop parameter 3).
In stop status, there are total 16 stop status parameters that can be set to display/not display: set frequency, bus voltage, DI input status, DO output status, analog input AI1 voltage, analog input AI2 voltage, panel potentiometer input voltage, PLC running step number, Actual speed display, PID settings, high-speed pulse input frequency and reserve, switch and display the selected parameter by pressing key orderly.
In running status,there are 5 running-status parameters:running frequency,setting frequency,bus voltage,output voltage, output current default display, and other display parameters: output power, output torque, DI input status, DO output status, analog input AI1 voltage, analog input AI2 voltage, panel potentiometer input voltage, linear speed, PID settings and PID feedback, etc, their display depends on function code
F6.01 and F6.02 switch and display the selected parameter by pressing key orderly.
Inverter powers off and then powers on again, the displayed parameters are the selected parameters before power-off.
3-4-3.Password settings
The inverter has password protection. When y0.01 become not zero, it is the password and will be work after exit from function code modified status. Press PRG key again, will display”----”. One must input the correct password to go to regular menu, otherwise, inaccessible.
To cancel the password protection function, firstly enter correct password to access and then set y0.01 to 0.
3-4-4.Motor parameter auto tunning
Choose vector control, one must input the motor ’s parameters in the nameplate accurately before running the inverter. PI9000-S series frequency inverter will match the motor’s standard parameters according to its nameplate. The vector control is highly depend on motor’s parameters. The parameters of the controlled motor must be inputted accurately for the good control performance.

Start DC braking, generally is used to restart the motor after it stops. Pre-excitation is used to create magnetic field for asynchronous motor and then start the motor to improve the response speed.
Start DC braking is only active when the start mode is the direct startup. The inverter firstly performs DC braking at the set value of DC braking current, after the start DC braking time is passed, and then start running. If the DC braking time is set to 0, the inverter will directly start and neglect DC braking. The largerDC braking current, the greater braking force.
If the startup mode is the asynchronous motor pre-excitation start, the inverter firstly creates magnetic field at the preset pre-excitation current, after the set pre-excitation time is passed and then start running. If the pre-excitation time is set to 0, the inverter will directly start and neglect pre-excitation.
Start DC braking current/pre-excitation current is the percentage of inverter rater current.

This parameter is valid only for asynchronous motors.
V/F slip compensation can compensate for the speed deviation of asynchronous motor when the increases, so as to keep stable speed when the load changes.
If V/F slip compensation gain is set to 100.0%, it means that the compensated deviation is equal to the rated motor slip under the rated motor load, while the rated motor slip can be calculated through b0 group of motor rated frequency and rated speed.
When adjust V/F slip compensation gain, generally it is based on the principle that the motor speed is same as the target speed. When the motor speed is different from target value, it is necessary to appropriately fine-tune the gain.

Overcurrent protection current stall

In the process of the inverter acceleration, when the output current exceeds the overcurrent stall protection current, the inverter stops ac/deceleration process and remains in the current operating frequency, and then continues to ac/decelerate upon the decline of the output current.
Overcurrent stall gain is used for adjusting inhibition overcurrent capability during ac/deceleration. The greater this value, the stronger inhibition overcurrent capability
Under the premise that the overcurrent does not occur, the best is the smaller gain setting.
For the small inertia load, the overcurrent stall gain should be small, otherwise which cause the slower system dynamic response. For the big inertia load, the overcurrent stall gain should be large, otherwise the poor inhibitory effect may cause overcurrent fault.
When the overcurrent stall gain is set to 0, the overcurrent stall function will be canceled.

This function is used in the front of motor overload fault protection, and sends a prealarm signal to the control system by DO. The warning coefficient is used to determine the extent of pre-alarm prior to motor overload protection. The higher the value, the smaller the extent of pre-alarm in advance.
When the cumulative amount of inverter output current is greater than the product of the inverse time curve of overload and F8.04, the inverter multi-function digital DO will output "Motor Overload Pre-Alarm" ON signal.

Overvoltage stall gain is used for adjusting inhibition overvoltage capability during deceleration. The greater this value, the stronger inhibition overvoltage capability under the premise that the overvoltage does not occur, the best is the smaller gain setting.
For the small inertia load, the overvoltage stall gain should be small, otherwise which cause the slower system dynamic response. For the big inertia load, the overvoltage stall gain should be large, otherwise the poor inhibitory effect may cause overvoltage fault.

In some applications, one set of PID parameters can not meet the needs of the entire operation, so need to adopt different PID parameters under different circumstances.
This group parameters are used for switching two sets of PID parameters. The way of setting of regulator parameters E2.16 ~ E2.18 are similar to the parameters E2.13 ~ E2.15.
Two sets of PID parameters can be switched by multi-functional digital terminals DI, and also can be switched automatically according to the PID deviation.
When DI multi-functional terminal selected, multi-function terminal function to be set to 43 (PID parameter switching terminal), select the parameter 1 (E2.13 ~ E2.15) when the terminal is invalid, select the parameter 2 when the terminal is valid (E2.16 ~ E2.18).

Different from ordinary digital quantity input terminals, virtual VDI state can have two setting modes which is selected by E3.06.
When selecting VDI state is determined by the state of the corresponding virtual VDO,
50
Chapter5.Function parameter
VDI is valid or invalid state depending on the VDO output valid or invalid, and VDIx only binding VDOx(x=1~5)
When choosing VDI state selection function code to set, through the binary bits of E3.05 , respectively determine the state of virtual input terminals.
Example of how to use VDI.
Example 1. Implement following function: “Inverter fault alarm and shuts down when AI1 input exceeds upper or lower frequency” .
Realize by following settings: Set VDI state decided by VDO, set VDI1 function as “ user defined fault 1” (E3.00=44); set VDI1 terminal state effective mode decided by VDO1
(E3.06=xxx0); set VDO1 output function as “AI1 input exceeds upper & lower frequency” (E3.11=31); so when AI1 input exceeds upper or lower frequency, VDO1 state is ON, VDI1 input terminal state is effective, VDI1 receive user defined fault 1, inverter then alarm fault no. 27 and shuts down.
Example 2. Implement following function: “Inverter run automatically after power-on”.
Realize by following settings: set VDI state decided by function code E3.05, set VDI1 function as “FORWARD” (E3.00=1); set VDI1 terminal state effective decided by function code (E3.06=xxx1); set VDI1 terminal state is effective (E3.05=xxx1); set command source as “terminal control” (F0.11=1); set protection selection as “no protection” (F7.22=0); so after inverter powered on and initialization complete, VDI1 detected effective, and it match forward running, then inverter starts running forwardly.

Above b0.00 to b0.05 are the motor nameplate parameters, which affects the accuracy of the measured parameters. Please set up according to the motor nameplate parameters. The excellent vector control performance needs the accurate motor parameters. The accurate identification of parameters is derived from the correct setting of rated motor parameters.
In order to guarantee the control performance, please configure your motor according to the inverter standards, the motor rated current is limited to between 30% to 100% of the inverter rated current. The motor rated current can be set, but can not exceed the inverter rated current. This parameter can be used to determine the inverter's overload protection capacity and energy efficiency for the motor.
It is used for the prevention of overheating caused by the self-cooled motor at low speed , or to correct for protecting the motor when the little change of the motor characteristics may affect the changes of the motor capacity.

The higher harmonics of power supply may damage the inverter. Thus, at some places where 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 interferences, one is the interference from electromagnetic noise in the surrounding environment to the inverter, and the other is t he interference from the inverter to the surrounding equipments.
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 30 meters, it needs to install output filter or reactor.
61
Chapter6.EMC(Electromagnetic Compatibility)
6-3-3.Remedies for the interferences from the surrounding electromagnetic equipments 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 interferences, 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 interferences from the inverter to the surrounding electromagnetic equipments
These noise interferences 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 interferences cause that the surrounding electric equipments suffer from the affect of electromagnetic or electrostatic induction. Further, the surrounding equipment produces error action. For different interferences, 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:
There are the distributed capacitance between the lead cables and the earth. The larger the distributed capacitance, the larger the leakage current; the distributed
62
Chapter6.EMC(Electromagnetic Compatibility) 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.

3.Set F0.03 = 8 (PV settings); E0.00 = 2 (MPPT mode);
4.After setting the parameters, press the RUN key, observe the operating frequency and the water situation. In normal light conditions, if running frequency is high but the water is running less, it indicates motor reversal phenomenon and need to modify the F0.24 =
1, then observe the water.
5.Set point of failure and fault reset time delay settings. If the customer needs to use the weak light, full of water, under-load, you can set detection point , the number of automatic reset and automatic reset time are set as per customer’s request.
(There are many different types of level switches, set parameters according to the site requirement. The following are examples.)
(1) When the sunlight is weak, the frequency inverter turn into hibernation. When the sunlight is strong, the frequency inverter automatically wake. Set E0.07 ~
E0.08 voltage detection value.
Take 380V voltage level as an example:
Parameter settings: F0.03 = 8 (PV settings);
E0.00 = 2 (MPPT mode);
E0.07 = 530 (PV wake voltage);
E0.08 = 400 (PV dormant voltage);
If the frequency inverter operate normally and when the sunlight is weak, the bus voltage becomes less than 400V, then the frequency inverter enters into hibernation.
When the sunlight is strong, the bus voltage is greater than 530V, the frequency inverter will automatically start running. Set the voltage of PV wake and sleep according to the situation. The two values can not be set at too close, if setting too close, the frequency inverter may start and stop frequently.
(2) Water level detection mode 1- Switch detection.
When using the switch detection, the test line lead to DI terminal, Then the corresponding terminal is set to 8. If used as a feedback input signal DI2, DI2 = 8.
When filled with water, DI2 signal is active, the frequency inverter will free stop. When the water level is below the detection value, the corresponding terminal is set to 1. (As with DI1 as the start signal, DI1=1), frequency inverter starts automatically.

Pump under-load detection mode 1
After water pump out of well, frequency inverter determine whether to run the water pump by setting a reference value.
F0.03 = 8 (PV settings));
F8.30 = 1 (off-load protection choose effective);
F8.31= d0.04 ÷ b0.03, suggests to subtract 0.05 to 0.1 based on the calculated result.
F8.32 = (off overload detection time, suggests to set as 10s)
E0.00 = 2 (MPPT mode);
E0.10 = 6000 (set out interval detection time)
Assuming the b0.03 = 5.1A, when pumping, d0.04 displayed as 4A, F8.31=4
÷
5.1=0.78, suggests to subtract by 0.05 to 0.1. F8.31 should be set between 68.4% - 73.4% ( F8.31 is set according to the actual situation). When setting F8.31 = 68.4%, current is less than
3.48, the delay time F8.32 is set to 60 (suggests to subtract setting time by 1Min ~ 3Min, set according to the actual situation), the inverter will free stop. E0.10 set out interval contained detectable, the frequency inverter runs automatically set off again into the detection status. If the pool is still no water detected, the frequency inverter will free stop again.

Pump under-load detection mode 2
After water pump out of the well, the inverter will shut down automatically.
Install level detection switch at a low water and the test line lead to DI terminal. DI terminal function selection is set to free stop and start forward. When the water level falls below the low level detection point, DI2 signal is active and the frequency inverter will free stop. When the water level is higher than the starting value detected, the frequency inverter starts automatically.

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.
※ Do not connect the AC input power to the inverter output terminals(U, V, W).
※ 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.

82
Chapter9.Mainternance and Repair
-- 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.

Appendix II RS485 Communication protocol
II-1 Communication protocol
II-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) Interface mode
RS485 hardware interface
(2) 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
(3) 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.

II-1-3 Protocol description
PI9000-S 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 PI9000-S 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 PI9000-S 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 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
88
Appendix II 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.

II-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
90
Appendix II 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++; for （ i=0;i<8;i++ ）
{ if （ crc_value&0x0001 ）
{
} 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 ） ;
}

Appendix II
II-3 Definition of communication parameter address
The section is about communication contents, it’s used to control the operation, status and related parameter settings of the inverter. Read and write function-code parameters (Some functional code is not changed, only for the manufacturer use or monitoring): the rules of labeling function code parameters address:
The group number and label number of function code is used to indicate the parameter address:
High byte: F0 to FB (F group), A0 to AF (E group), B0 to BF(B group),C0 to
C7(Y group),70 to 7F (d group) low byte: 00 to FF
For example: address F3.12 indicates F30C; Note: L0 group parameters: neither read nor change; d group parameters: only read, not change.
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 F 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 67(Y group)low byte:00 to FF
For example:
Function code F3.12 can not be stored into EEPROM, address indicates as
030C; function code E3.05 can not be stored into EEPROM, address indicates as
4305; the address indicates that only writing RAM can be done and reading can not be done, when reading, it is invalid address. For all parameters, you can also use the command code 07H to achieve the function.

9: 115200BPS
This parameter is used to set the data transfer rate between the host computer and the inverter. Note: the baud rate must be set to the same for the host computer and the inverter, otherwise communication can not be achieved. The larger baud rate, the faster communication speed.
F9.01
Data format
Setting range
Default 0
0: no parity: data format <8, N, 2>
1: even parity: data format <8, E, 1>
2: odd parity: data format <8, O, 1>
3: no parity: data format <8-N-1>
Note: the set data for the host computer and the inverter must be the same.
F9.02
This unit address Default
Setting range 1 to 247, 0for broadcast address
1
When the address of this unit is set 0, that is broadcast address, the broadcasting function for the host computer can be achieved.
The address of this unit has uniqueness (in addition to the broadcast address), which is the basis of peer-to-peer communication for the host computer and the inverter.
2ms
F9.03
Response delay Default
Setting range 0 to 20ms
Response delay: it refers to the interval time from the end of the inverter receiving data to the start of it sending data to the host machine. If the response delay is less than the system processing time, then the response delay time is subject to the system processing time; If the response delay is longer than the system processing time, after the system finises the data processing, and continues to wait until the response delay time, and then sends data to the host computer.
F9.04
Communication timeout time
Setting range
Default
0.0 s(invalid)
0.1 to 60.0s
0.0 s
Communication time-out parameter is not valid when the function code is set to 0.0s.
96
Appendix II
Whenthe function code is set to valid, if the interval time between one communication and the next communication exceeds the communication time-out time, the system will report communication failure error (Fault ID Err.16). Generally, it is set to invalid. If the parameter can be set to monitor the communication status in continuous communication system.
F9.05
Communication protocol selection
Setting range
Default
0: non-standard Modbus protocol
1: standard Modbus protocol
0
F9 .05=1: select standard Modbus protocol.
F9 .05=0: when reading command, the number of bytes returned by slave is more 1 byte than standard Modbus protocol.
F9.06
Communication read current resolution
Setting range
Default
0: 0.01A
1: 0.1A
0
Used to determine the current output units when communication reads output current.
