1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time, or when the motor is reused after being kept, or when periodical
inspection is performed, it should conduct motor insulation inspection so as to avoid damaging the inverter
because of the insulation failure of the motor windings. The motor wires must be disconnected from the
inverter during the insulation inspection. It is recommended to use the 500V megameter, and the insulating
resistance measured should be at least 5MΩ.
1.2.2 Thermal Protection of the Motor
If the ratings of the motor does not match those of the inverter, especially when the rated power of the
inverter is higher than the rated power of the motor, the relevant motor protection parameters in the in the
inverter should be adjusted, or thermal relay should be mounted to protect the motor.

KE300 Inverter
Safety and Precautions
1.2.3 Running with Frequency higher than Standard Frequency
This inverter can provide output frequency of 0Hz to 3000Hz. If the user needs to run the inverter with
frequency of more than 50Hz, please take the resistant pressure of the mechanical devices into
consideration.
1.2.4 Vibration of Mechanical Device
The inverter may encounter the mechanical resonance point at certain output frequencies, which can be
avoided by setting the skip frequency parameters in the inverter.
1.2.5 Motor Heat and Noise
Since the output voltage of inverter is PWM wave and contains certain harmonics, the temperature rise,
noise and vibration of the motor will be higher than those at power frequency.
1.2.6 Voltage-sensitive Device or Capacitor Improving Power Factor at the Output Side
Since the inverter output is PWM wave, if the capacitor for improving the power factor or voltage-sensitive
resistor for lightning protection is mounted at the output side, it is easy to cause instantaneous over current
in the inverter, which may damage the inverter. It is recommended that such devices not be used.
1.2.7 Switching Devices like Contactors Used at the Input and Output terminal
If a contactor is installed between the power supply and the input terminal of the inverter, it is not allowed to
use the contactor to control the startup/stop of the inverter. If such contactor is unavoidable, it should be
used with interval of at least one hour. Frequent charge and discharge will reduce the service life of the
capacitor inside the inverter. If switching devices like contactor are installed between the output end of the
inverter and the motor, it should ensure that the on/off operation is conducted when the inverter has no
output. Otherwise the modules in the inverter may be damaged.
1.2.8 Use under voltage rather than rated voltage
If the KE series inverter is used outside the allowable working voltage range as specified in this manual, it
is easy to damage the devices in the inverter. When necessary, use the corresponding step-up or
step-down instruments to change the voltage.
1.2.9 Change Three-phase Input to Two-phase Input
It is not allowed to change the KE series three-phase inverter into two-phase one. Otherwise, it may cause
fault or damage to the inverter.
1.2.10 Lightning Impulse Protection
The series inverter has lightning over current protection device, and has certain self-protection capacity
against the lightning. In applications where lightning occurs frequently, the user should install additional
protection devices at the front-end of the inverter.

KE300 Inverter
Safety and Precautions
1.2.11 Altitude and Derating
In areas with altitude of more than 1,000 meters, the heat sinking effect of the inverter may turn poorer due
to rare air. Therefore, it needs to derate the inverter for use. Please contact our company for technical
consulting in case of such condition.
1.2.12 Certain Special Use
If the user needs to use the inverter with the methods other than the recommended wiring diagram in this
manual, such as shared DC bus, please consult our company.
1.2.13 Note of Inverter Disposal
The electrolytic capacitors on the main circuit and the PCB may explode when they are burnt. Emission of
toxic gas may be generated when the plastic parts are burnt. Please dispose the inverter as industrial
wastes.
1.2.14 Adaptable Motor
1) The standard adaptable motor is four-pole squirrel-cage asynchronous induction motor. If such motor is
not available, be sure to select adaptable motors in according to the rated current of the motor. In
applications where drive permanent magnetic synchronous motor is required, please consult our company;
2) The cooling fan and the rotor shaft of the non-variable-frequency motor adopt coaxial connection. When
the rotating speed is reduced, the cooling effect will be poorer. Therefore, a powerful exhaust fan should be
installed, or the motor should be replaced with variable frequency motor to avoid the over heat of the
motor.
3) Since the inverter has built-in standard parameters of the adaptable motors, it is necessary to perform
motor parameter identification or modify the default values so as to comply with the actual values as much
as possible, or it may affect the running effect and protection performance;
4) The short circuit of the cable or motor may cause alarm or explosion of the inverter. Therefore, please
conduct insulation and short circuit test on the newly installed motor and cable. Such test should also be
conducted during routine maintenance. Please note that the inverter and the test part should be completely
disconnected during the test.

Product Information
2.7 Routine Maintenance of Inverter
2.7.1 Routine Maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of the devices
in the inverter, which may cause potential fault of the inverter or reduce the service life of the inverter.
Therefore, it is necessary to carry out routine and periodical maintenance on the inverter.
Routine inspection Items include:
1)
Whether there is any abnormal change in the running sound of the motor;
2)
Whether the motor has vibration during the running;
3)
Whether there is any change to the installation environment of the inverter;
4)
Whether the inverter cooling fan works normally;
5)
Whether the inverter has over temperature.
Routine cleaning:
1)
The inverter should be kept clean all the time.
2)
The dust on the surface of the inverter should be effectively removed, so as to prevent the dust
entering the inverter. Especially the metal dust is not allowed.
3)
The oil stain on the inverter cooling fan should be effectively removed.
2.7.2 Periodic Inspection
Please perform periodic inspection on the places where the inspection is a difficult thing.
Periodic inspection Items include:
1)
Check and clean the air duct periodically;
2)
Check if the screws are loose;
3)
Check if the inverter is corroded;
4)
Check if the wire connector has arc signs;
5)
Main circuit insulation test.
Remainder: When using the megameter (DC 500V megameter recommended) to measure the insulating
resistance, the main circuit should be disconnected with the inverter. Do not use the insulating resistance
meter to test the insulation of control circuit. It is not necessary to conduct the high voltage test (which has
been completed upon delivery).
2.7.3 Replacement of Vulnerable Parts for Inverter
The vulnerable parts of the inverter include cooling fan and filter electrolytic capacitor, whose service life
depends on the operating environment and maintenance status. General service life is shown as follows:
Part Name
Service Life
Fan
2~3 years
Electrolytic capacitor
4~5 years
The user can determine the year of replacement according to the operating time.
23
KE300 Inverter
1)
Product Information
Cooling fan
Possible reason for damage: Bearing is worn and blade is aging.
Judging criteria: Whether there is crack on the blade and whether there is abnormal vibration noise upon
startup.
2)
Filter electrolytic capacitor
Possible reason for damage: Input power supply in poor quality, high ambient temperature, frequent load
jumping, and electrolyte aging.
Judging criteria: Whether there is liquid leakage and whether the safe valve has projected, and measure
the static capacitance, and the insulating resistance.
2.7.4 Storage of Inverter
Upon acquiring the inverter, the user should pay attention to the following points regarding the temporary
and long-term storage of the inverter:
1)
Pack the inverter with original package and place back into the packing box of our company.
2)
Long-term storage will degrade the electrolytic capacitor. Thus, the product should be powered up
once every 2 years, each time lasting at least five hours. The input voltage should be increased slowly to
the rated value with the regulator.
2.8 Instructions on Warranty of Inverter
Free warranty only applies to the inverter itself.
1)
MICNO provides 18 month warranty (starting from the date of original shipment as indicated on the
barcode) for the failure or damage under normal use conditions. If the equipment has been used for over
18 months, reasonable repair expenses will be charged.
2)
Reasonable repair expenses will be charged for the following situations within 18 months:
a)
The equipment is damaged because the user fails to comply with the requirements of the user’s
manual;
b)
Damage caused by fire, flood and abnormal voltage;
3)
Damage caused when the inverter is used for abnormal function.
The service expenses will be calculated according to the standard of the manufacturer. If there is any
agreement, the agreement should prevail.

Mechanical and Electric Installation
Chapter 3 Mechanical and Electric Installation
3.1 Mechanical Installation
3.1.1 Installation environment
1) Ambient temperature: The ambient temperature exerts great influences on the service life of the inverter
and is not allowed to exceed the allowable temperature range (-10℃ to 50℃).
2) The inverter should be mounted on the surface of incombustible articles, with sufficient spaces nearby
for heat sinking. The inverter is easy to generate large amount of heat during the operation. The inverter
should be mounted vertically on the base with screws.
3) The inverter should be mounted in the place without vibration or with vibration of less than 0.6G, and
should be kept away from such equipment as punching machine.
4) The inverter should be mounted in locations free from direct sunlight, high humidity and condensate.
5) The inverter should be mounted in locations free from corrosive gas, explosive gas or combustible gas.
6) The inverter should be mounted in locations free from oil dirt, dust, and metal powder.

Mechanical and Electric Installation
3.1.2 Heat dissipation should be taken into account during the mechanical installation. Please pay
attention the following items:
1) Install the inverter vertically so that the heat may be expelled from the top. However, the equipment
cannot be installed upside down. If there are multiple inverters, parallel installation is a better choice. In
applications where the upper and lower inverters need to be installed, please refer to Figure 3-1 “KE300
Series Inverter Installation Diagram” and install an insulating splitter.
2) The mounting space should be as indicated as Figure 3-1, so as to ensure the heat dissipation space of
the inverter. However, the heat dissipation of other devices in the cabinet should also be taken into
account.
3) The installation bracket must be flame retardant.
4) In the applications where there are metal dusts, it is recommended to mount the radiator outside the
cabinet. In this case, the space in the sealed cabinet should be large enough.

There is no phase sequence requirement for the cable connection at the input side of the inverter,
b) DC bus (+) and (-) terminals:
Note that the (+) and (-) terminals of DC bus have residual voltage right after power-on. It needs to wait
until the CHARGE indictor is OFF and make sure that the voltage is less than 36V prior to wiring
connection. Otherwise there may be danger of electric shock.
33
KE300 Inverter
Mechanical and Electric Installation
When selecting external brake unit for the inverter above 18.5kW, the poles of (+) and (-) should not be
connected reversely, or it may damage the inverter and even cause fire.
The wiring length of the brake unit should not exceed 10 meters. Twisted wires or pair wires should be
used and connected in parallel.
Do not connect the brake resistor directly to the DC bus, or it may damage the inverter and even cause fire.
c) Connecting terminals (+) and PB of brake resistor:
The connecting terminals of the brake resistor are effective only for the inverter of less than 30kW with
built-in brake unit.
The prototype of brake resistor can refer to the recommended value and the wiring length should be less
than 5 meters. Otherwise it may damage the inverter.
d) Connecting terminals P1 and (+) of external DC reactor:
For the inverter above 18.5kW with external reactor, when assembling, remove the connector between
terminals P1 and (+), and connect a DC reactor instead.
e) Terminals U, V, W at the output side of the inverter:
The inverter output side cannot connect to the capacitor or surge absorber. Otherwise, it may cause
frequent inverter protection and even damage the inverter.
In case the motor cable is too long, it may generate electrical resonance easily due to the impact of
distributed capacitance, thus damaging the motor insulation or generating higher leakage current to invoke
over current protection of the inverter. When the length of motor cable is longer than 100 meters, it needs
to install a AC output reactor.
f) Earth terminal PE
:
This terminal should be earthed reliably, with resistance of earth cable of less than 0.1Ω. Otherwise, it may
cause fault or damage the inverter.
Do not share the earth terminal
and zero line of the power supply.

Description: When operating on level 3 menu, press PRG key or ENTER key to return to level 2 menu. The
difference between PRG key and ENTER key is described as follows: Pressing ENTER KEY will save the
setup parameter and return to the level 2 menu and then automatically shift to the next function code, while
pressing PRG key will directly return to level 2 menu without saving the parameter, and it will return to the
current function code.
Example: Modify the function code P3-02 from 10.00Hz to 15.00Hz. (The bold-type word indicates the
flashing bit.)

In level 3 menu, if there is no flashing bit, it indicates that the function code cannot be modified. The
possible reasons include:
1) The function code is an unchangeable parameter, such as actual detection parameter, running record
parameter, etc.
2) The function code cannot be modified in running status. It can be modified only after the unit is stopped.
4.3 Power-on Initialization
Firstly the system initializes during the inverter power-on, and LED displays “8.8.8.8.8.8”. After initialization,
the inverter is in fault protection status if a fault happens, or the inverter is in stand-by status
4.4 Fault Protection
In fault status, inverter will display fault code & record output current, output voltage, etc. For details,
please refer to P9 (fault and protection) parameter group. Fault can be reset via STOP/RST key or external
terminals.

KE300 Inverter
Operation and Display
4.5 Stand By
In stop or stand by status, parameters of multi-status can be displayed. Whether or not to display this
parameter can be chosen through function code P7-05 (Stop status display parameter) according to binary
bits.
In stop status, there are thirteen parameters can be chosen to display or not. They are: setting frequency,
bus voltage, DI input status, DO output status, analog input AI1 voltage, analog input Al2 voltage, radiator
temperature, count value, actual length, PLC running step, load speed display, PID setting, HDI input pulse
frequency. The displaying of the chosen parameters can be switched in sequence by press “
” button.
Power on after power-off, the displayed parameters would be default considered as the chosen parameters
before power-off.
4.6 Running
In running status, there are thirty two parameters can be chosen to display or not through function code
P7-04 (running status display parameter 2) according to binary bits. They are: running frequency, setting
frequency, DC bus voltage, output voltage, output current, output torque, DI input status, DO output status,
analog input AI1 voltage, analog input AI2 voltage, radiator temperature, actual count value, actual length,
line speed, PID setting, PID feedback, etc. The displaying of the chosen parameters can be switched in
sequence by pressing “
” button.
4.7 Password Setting
The inverter provides user password protection function. When PP-00 is set to non-zero value, it indicates
the user password, and the password protection turns valid after exiting the function code editing status.
When pressing PRG key again, “------“ will be displayed, and common menu cannot be entered until user
password is input correctly.
To cancel the password protection function, enter with password and set PP-00 to “0”.
4.8 Motor Parameters Autotuning
To select the vector control running mode, it must input the nameplate parameter of the motor accurately
prior to the running of the inverter. The Inverter will select standard motor parameters matching the
nameplate parameter. Since the vector control mode relies highly on the motor parameters, it must acquire
the accurate parameters of the controlled motor to ensure the good control performance.
The procedures for the automatic tuning of motor parameters are described below:
First, select the command source (P0-02) as the command channel of the operation keypad. Second, input
the following parameters in accordance with the actual motor parameters:
P1-01: Rated motor power
P1-02: Rated motor voltage
P1-03: Rated motor current
P1-04: Rated motor frequency
P1-05: Rated rotation speed of motor
If the motor is completely disconnected from the load, set P1.11 to “2” (complete tuning), and press RUN
key on the keyboard keypad, then the inverter will automatically calculate the following parameters:
41
KE300 Inverter
Operation and Display
P1-06: Stator resistance
P1-07: Rotor resistance
P1-08: Leakage inductance
P1-09: Mutual inductance
P1-10: Current without load
Finally, complete the automatic tuning of motor parameters.
If the motor cannot be completely disconnected with the load, set P1-11 to “1” (static tuning), and then
press RUN key on the keyboard panel.
The following motor parameters can be calculated automatically:
P1-06: Stator resistance
P1-07: Rotor resistance
P1-08: Leakage inductive reactance

Function Parameter List
Chapter 5 Function Parameter List
The function parameters of KE300 series inverter have been divided into 19 groups including P0~PP, A0,
U0 according to the function. Each function group contains certain function codes. For example, “P1-10”
means the tenth function code in the P1 function group. P0~PE are basic function parameter groups; PF is
factory parameter group (users are forbidden to access); A0 is torque control function parameter group; U0
is monitor function parameter group.
If PP-00 is set to non-zero value, it means parameter protection password is set, and the parameter menu
cannot be entered until correct password is input. To cancel the password, please set PP-00 to “0”.
A0 and U0 are default hidden parameter groups, which can be displayed by modifying PP-02.
The instruction of the symbols in function parameter list is as following:
“○”:means that the parameter setting value can be modified on stop and running status.
“◎”:means that the parameter setting value cannot be modified on the running status.
“●”:means that the value of the parameter is the real detection value which cannot be modified.

When the auxiliary frequency source is used as independent frequency reference channel (i.e. frequency
source switching from A to B), it is used in the same way as the main frequency source. Please refer to
P0-03.
When the auxiliary frequency source is used as combination reference, please note:
1. If the auxiliary frequency source is keypad reference, the frequency (P0-08) is invalid, and it needs to
adjust the main reference frequency through the keys “▲”and “▼” of the keyboard (or UP and DOWN
of multifunctional input terminals).
2. If the auxiliary frequency source is analog input reference (AI1, AI2) or pulse input reference, 100% of
input corresponds to the auxiliary frequency source range (refer to P0-05 and P-06).
3. If the frequency source is pulse input reference, it is similar to the analog input reference.
Note: P0-03 and P0-04 can’t be set to be the same value. Otherwise, disorder will occur.

Parameter Description
It is used to define the source of frequency upper limit. The frequency upper limit can be sourced from
either digital setting (P0-12) or analog input. When the analog input is used to set the frequency upper limit,
100% of analog input setting is relative to P0-12.

Carrier frequency
Setting range
Factory default
Model depend
1.0kHz ~ 16.0kHz
Carrier frequency will affect the noise of motor and the EMI of inverter.
If the carrier frequency is increased, it will cause better current wave, less harmonic current and lower
noise of motor.
Notice:
The factory default is optimal in most cases. Modification of this parameter is not recommended.
If the carrier frequency exceeds the factory default, the inverter must be derated because the
higher carrier frequency will cause more switching loss, higher temperature rise of inverter and
stronger electromagnetic interference.
If the carrier frequency is lower than the factory default, it is possible to cause less output torque of
motor and more harmonic current.
The effect of modifying carrier frequency is as following:

The speed dynamic response characteristics of the vector control can be adjusted by setting the
proportional coefficient and integration time of the speed regulator.
Increasing the proportional gain or reducing the integration time can accelerate the dynamic response of
the speed loop. However, if the proportional gain is too large or the integration time is too short, it will cause
the oscillation of the system.

For the application which over voltage fault happens frequently during deceleration, the over excitation
gain needs to be increased. But the current would be increased if the over excitation is too bigger, so you
need to set the suitable over excitation gain.
For the small inertia situation, voltage doesn’t increase during motor deceleration, please set over

The above function codes define the relationship between the analog input voltage and analog input
setting value.
When the analog input voltage is bigger than P4-15 (maximum input of AI curve 1), then calculate the
analog voltage according to maximum input. When the analog input voltage is smaller than P4-13
(minimum input of AI curve 1), then calculate the analog voltage with minimum input or 0.0% according to
P4-34 (AI below minimum input setting selection).
When the analog input is current input, 1mA current equals to 0.5V voltage.
AI1 input filter time is used to set AI1 software filter time, when the site analog signal can be easily
disturbed, please increase filter time to stable the detected analog signal, but the bigger the filter time is,
the slower the response speed of the analog detection is . So please set this parameter according to the
situation.
In difference applications, 100% of analog input corresponds to different nominal values. Refer to all the

the stronger the adjustment intensity is. When this parameter is 100, indicating the deviation between PID
feedback value and given value is 100%, the adjustment amplitude of the PID regulator on the output
frequency command is maximum frequency.
Integration time Ti1: It decides the intensity of the integration adjustment of PID regulator. The shorter the
integration time is, the stronger the adjustment intensity is. Integration time is the time within which the
adjustment value reaches maximum frequency when the deviation between PID feedback value and given
value is 100%.
Differential time Td1: It decides the intensity of the deviation change rate of PID regulator. The longer the
differential time is, the stronger the adjustment intensity is. Differential time is the time within which if the

In some applications, one group PID parameter is not enough, different PID parameters would be adopted
according to the situation.
The function codes are used to switch two groups PID parameter. The setting mode of the regulator
parameters PA-15~PA-17 is similar as PA-05~PA-07’s.
Two groups PID parameter can be switched via DI terminal, or switched according to PID deviation
automatically.
When selection is automatic switching: when the deviation absolute value between given and feedback is
smaller than PA-19 (PID parameter switching deviation 1), PID parameter selection is group 1. When the
deviation absolute value between given and feedback is bigger than PA-20 (PID parameter switching
deviation 2), PID parameter selection is group 2. When the deviation absolute value between given and
feedback is between PA-19 and PA-20, PID parameter is the linear interpolation of two groups PID

KE300 Inverter
Parameter Description
wobble frequency is limited by the frequency upper limit and frequency lower limit.
The wobble amplitude is relative to the central frequency (variable wobble amplitude, select FB-00=0):
wobble amplitude: AW=frequency source: F0-07 × wobble amplitude: FB-01.
The wobble amplitude is relative to the maximum frequency (fixed wobble amplitude, select FB-00=1):
wobble amplitude: AW=maximum frequency: F0-10 × wobble amplitude: FB-01.
Sudden jump frequency=wobble amplitude: AW × sudden jump frequency amplitude: FB-02. That is the
value of sudden jump frequency relative to the wobble amplitude when the wobble frequency is running.
If the wobble amplitude relative to the central frequency (variable wobble amplitude, select FB-00=0) is
selected, the sudden jump frequency is a variable value.
If the wobble amplitude relative to the maximum frequency (fixed wobble amplitude, select FB-00=1) is
selected, the sudden jump frequency is a fixed value.

The speed variation rate of the motor and load is determined by the difference between the motor output
torque and the load torque in torque control mode. So the motor speed may change rapidly, and causes
noise or mechanical stress too big, etc. The motor speed can change smoothly via setting torque control
ACC/DEC time.
Torque control ACC/DEC time should be set to 0.00s for the application which needs torque responding
rapidly.
For example: two motors drag one load by hard wiring, to make sure uniform distribution of loading, one
inverter is set to the master & adopts speed control mode, the other is set to the slave & adopts torque
control. The torque command of the slave is set to the actual output torque of the master, the slave torque
needs to follow the master rapidly, then the torque control ACC/DEC time should be set to 0.00s.

EMC (Electromagnetic Compatibility)
Chapter 7 EMC (Electromagnetic Compatibility)
7.1 Definition
Electromagnetic compatibility is the ability of the electric equipment to work in the electromagnetic
interference environment and implement its function stably without interferences in the electromagnetic
environment.
7.2 EMC Standard Description
In accordance with the requirements of the national standard GB/T12668.3, the inverter needs to comply
with electromagnetic interference and anti-electromagnetic interference requirements.
Products apply the latest international standard—IEC/EN61800-3: 2004 (Adjustable speed electrical power
drive systems part 3: EMC requirements and specific test methods), which is equivalent to the national
standard GB/T12668.3.
IEC/EN61800-3 assesses the inverter in terms of electromagnetic interference and anti-electronic
interference. Electromagnetic interference mainly tests the radiation interference, conduction interference
and harmonics interference on the inverter (required for the inverter for civil use). Anti-electromagnetic
interference mainly tests the conduction interference rejection, radiation interference rejection, surge
interference rejection, fast and mutable pulse group interference rejection, ESD interference rejection and
power low frequency end interference rejection (specific test items including: 1. Interference rejection tests
of input voltage sag, interrupt and change; 2. Phase conversion interference rejection test; 3. Harmonic
input interference rejection test; 4. Input frequency change test; 5. Input voltage unbalance test; 6. input
voltage fluctuation test).
The tests should be conducted strictly in accordance with the above requirements of IEC/ EN61800-3, and
the products of our company are installed and used according to Section 7.3 and have good
electromagnetic compatibility in general industry environment.
7.3 EMC Guide
7.3.1 Harmonic effect
Higher harmonics of power supply may damage the inverter. Thus, at some places where mains quality is
rather poor, it is recommended to install AC input reactor.
7.3.2 Electromagnetic interference and installation precautions
There are two kinds of electromagnetic interferences, one is interference of electromagnetic noise in the
surrounding environment on the inverter, and the other is interference of inverter on the surrounding
equipment.
Installation precautions:
1)
The earth wires of the Inverter and other electric products should be well grounded;
2) The power input and output power cables of the inverter and weak current signal cables (e.g. control
line) should not be arranged in parallel and vertical arrangement is preferable.
154
KE300 Inverter
EMC (Electromagnetic Compatibility)
3) It is recommended that the output power cables of the inverter employ shield cables or steel pipe
shielded cables and that the shielding layer be earthed reliably. The lead cables of the equipment suffering
interferences are recommended to employ twisted-pair shielded control cables, and the shielding layer
should be earthed reliably.
4)
When the length of motor cable is longer than 100 meters, it needs to install output filter or reactor.
7.3.3 Handling method for the interferences of the surrounding equipment on the inverter
The electromagnetic interference on the inverter is generated because plenty of relays, contactors and
electromagnetic brakes are installed near the inverter. When the inverter has error action due to the
interferences, the following measures can be taken:
1)
Install surge suppressor on the devices generating interference;
2)
Install filter at the input end of the inverter. Refer to Section 7.3.6 for the specific operations;
3) The lead cables of the control signal cable of the inverter and the detection line employ shielded
cable and the shielding layer should be earthed reliably.
7.3.4 Handling method for the interferences of inverter on the surrounding equipment
These interferences include two types: one is radiation interference of the inverter, and the other is
conduction interference of the inverter. These two types of interferences cause the surrounding electric
equipment to suffer electromagnetic or electrostatic induction. The surrounding equipment hereby
produces error action. For different interferences, it can be handled by referring to the following methods:
1) For the measuring meters, receivers and sensors, their signals are generally weak. If they are placed
nearby the inverter or together with the inverter in the same control cabinet, they are easy to suffer
interference and thus generate error actions. It is recommended to handle with the following methods: Put
in places far away from the interference source; do not arrange the signal cables with the power cables in
parallel and never bind them together; both the signal cables and power cables employ shielded cables
and are well earthed; 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 cycles; install EMC output filter in more severe conditions.
2) When the equipment suffering interferences and the inverter use the same power supply, it may
cause conduction interference. If the above methods cannot remove the interference, it should install EMC
filter between the inverter and the power supply (refer to Section 7.3.6 for the prototyping operation); the
surrounding equipment is separately earthed, which can avoid the interference caused by the leakage
current of the inverter’s earth wire when common earth mode is adopted.
3) The surrounding equipment is separately earthed, which can avoid the interference caused by the
leakage current of the inverter’s earth wire when common earth mode is adopted.
7.3.5 Leakage current and handling
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 influencing the leakage current to the earth and the solutions:
There are distributed capacitance between the lead cables and the earth. The larger the distributed
155
KE300 Inverter
EMC (Electromagnetic Compatibility)
capacitance is, the larger the leakage current will be. The distributed capacitance can be reduced by
effectively reducing the distance between the inverter and the motor. The higher the carrier frequency is,
the larger the leakage current will be. The leakage current can be reduced by reducing the carrier
frequency. However, reducing the carrier frequency may result in addition of motor noise. Note that
additional installation of reactor is also an effective method to remove the leakage current.
The leakage current may increase following the addition of circuit current. Therefore, when the motor
power is high, the corresponding leakage current will be high too.
2)
Factors of producing leakage current between the cables and solutions:
There is distributed capacitance between the output cables of the inverter. If the current passing the lines
has higher harmonic, it may cause resonance and thus result in leakage current. If 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 thermal
relay not be installed before the motor when using the inverter, and that electronic over current protection
function of the inverter be used instead.
7.3.6 Precautions for Installing EMC input filter at the input end of power supply
1) 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 should be large and the metal ground of the installing
cabinet should be well earthed and have good conduction continuity. Otherwise there may be danger of
electric shock and the EMC effect may be greatly affected.
2) Through the EMC test, it is found that the filter ground must be connected with the PE end of the
inverter at the same public earth. Otherwise the EMC effect may be greatly affected.
3)
The filter should be installed at a place close to the input end of the power supply as much as
possible.

KE300 Inverter
MODBUS Communication Protocol
Chapter 9 MODBUS Communication Protocol
KE300 series inverter provides RS485 communication interface, and adopts MODBUS communication
protocol. User can realize centralized monitoring through PC/PLC, host computer, and also can set
inverter’s operating commands, modify or read function parameters, read operating status and fault
information, etc.
9.1 About Protocol
This serial communication protocol defines the transmission information and use format in the series
communication. It includes the formats of master-polling, broadcast and slave response frame, and master
coding method with the content including slave address (or broadcast address), command, transmiting
data and error checking. The response of slave adopts the same structure, including action confirmation,
returning the data and error checking etc. If slave takes place the error while it is receiving the information
or cannot finish the action demanded by master, it will send one fault signal to master as a response.
9.2 Application Method
The inverter could be connected into a “Single-master Multi-slave” PC/PLC control network with RS485
bus.
9.3 Bus Structure
(1) Interface mode
RS485
(2) Transmission mode
There provide asynchronous series and half-duplex transmission mode. At the same time, just one can
send the data and the other only receives the data between master and slave. In the series asynchronous
communication, the data is sent out frame by frame in the form of message.
(3) Topological structure
In Single-master Multi-slave system, the setup range of slave address is 0 to 247. 0 refers to broadcast
communication address. The address of slave must be exclusive in the network. That is basic condition of
MODBUS communication.
9.4 Protocol Description
KE300 series inverter communication protocol is a kind of asynchronous serial master-slave
communication protocol. In the network, only one equipment (master) can build a protocol (Named as
“Inquiry/Command”). Other equipments (slave) response “Inquiry/Command” of master only by providing
the data, or doing the action according to the master’s “Inquiry/Command”. Here, master is Personnel
Computer, Industrial control equipments or Programmable logical controller, and the slave is inverter or
other communication equipments with the same communication protocol. Master not only can visit some
slave separately for communication, but also sends the broadcast information to all the slaves. For the
single “Inquiry/Command” of master, all of slaves will return a signal that is a response; for the broadcast
information provided by master, slave needs not feedback a response to master.
165
KE300 Inverter
MODBUS Communication Protocol
9.5 Communication Data Structure
MODBUS protocol communication data format of KE300 series inverter is shown as following:
In RTU mode, the Modbus minimum idle time between frames should be no less than 3.5 bytes. The
checksum adopts CRC-16 method. All data except checksum itself sent will be counted into the calculation.
Please refer to section: CRC Check for more information. Note that at least 3.5 bytes of Modbus idle time
should be kept and the start and end idle time need not be summed up to it.
The entire message frame must be transmitted as a continuous data stream. If a idle time is more than 1.5
bytes before completion of the frame, the receiving device 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 3.5 bytes interval following a previous message, the receiving device will consider it as a continuation
of the previous message. Because of the frame’s confusion, at last the CRC value is incorrect and
communication fault will occur.

9.6.3 CRC checking
In RTU mode, messages include an error-checking field that is based on a CRC method. The CRC field
checks the contents of the entire message. The CRC field is two bytes, containing a 16-bit binary value.
The CRC value is calculated by the transmitting device, which appends the CRC to the message. The
receiving device recalculates a CRC during receipt of the message, and compares the calculated value to
the actual value received in the CRC field. If the two values are not equal, an error results.
167
KE300 Inverter
MODBUS Communication Protocol
The CRC is started by 0xFFFF. Then a process begins of applying successive eight-bit bytes of the
message to the current contents of the register. Only the eight bits of data in each character are used for
generating the CRC. Start and stop bits, and the parity bit, do not apply to the CRC.
During generation of the CRC, each eight-bit character is exclusive ORed with the register contents. Then
the result is shifted in the direction of the least significant bit (LSB), with a zero filled into the most
significant bit (MSB) position. The LSB is extracted and examined. If the LSB was a 1, the register is then
exclusive ORed with a preset, fixed value. If the LSB was a 0, no exclusive OR takes place. This process is
repeated until eight shifts have been performed. After the last (eighth) shift, the next eight-bit byte is
exclusive ORed with the register's current value, and the process repeats for eight more shifts as
described above. The final contents of the register, after all the bytes of the message have been applied, is
the CRC value.
When the CRC is appended to the message, the low byte is appended first, followed by the high byte. The
following are C language source code for CRC-16.
unsigned int crc_cal_value(unsigned char *data_value,unsigned char data_length)
{
int i;
unsigned int crc_value = 0xffff;
while(data_length--)
{
crc_value ^= *data_value++;
for(i=0;i<8;i++)
{
if(crc_value&0x0001)
crc_value = (crc_value>>1)^0xa001;
else
crc_value = crc_value>>1;
}
}
return(crc_value);
}
9.6.4 Address definition of communication parameter
Here is about address definition of communication parameter. It’s used to control the inverter operation,
status and related parameter setting.
(1) The mark rules of function code parameters address:
The group number and mark of function code is the parameter address for indicating the rules.
P0~PF group parameter address:
High byte: F0 to FF, low byte: 00 to FF
A0 group parameter address:
High byte: A0, low byte: 00 to FF
U0 group parameter address:
High byte: 70H, low byte: 00 to FF
For example: P3-12, address indicates to F30C
PC-05, address indicates to FC05
A0-01, address indicates to A001
U0-03, address indicates to 7003
168
KE300 Inverter
MODBUS Communication Protocol
Note:
1.
Group PF: Either the parameter cannot be read, nor be changed.
2.
Group U0: Only for reading parameter, cannot be changed parameters.
3.
Some parameters cannot be changed during operation; some parameters regardless of what kind of
status the inverter in, the parameters cannot be changed. Change the function code parameters, pay
attention to the scope of the parameters, units, and relative instructions.
Besides, due to EEPROM be frequently stored, it will reduce the lifetime of EEPROM. So in the
communication mode, some function code needn’t be stored, only change the RAM value. To achieve this
function, change high order P of the function code into zero.
Corresponding function code addresses are indicated below:
P0~PF group parameter address:
High byte: 00 to FF, low byte: 00 to FF
A0 group parameter address:
High byte: 40, low byte: 00 to FF
U0 group parameter address:
High byte: 70H, low byte: 00 to FF
For example: P3-12, address indicates to 030C
PC-05, address indicates to 0C05
A0-01, address indicates to 4001
These addresses can only act writing RAM, it cannot act reading. When act reading, it is invalid address.

9.7 PD Group Communication Parameter Description
Baud Rate
Factory Setting
6005
0:300BPS
1:600BPS
2:1200BPS
3:2400BPS
4:4800BPS
5:9600BPS
6:19200BPS
7:38400BPS
Pd-00
Setting range
This parameter is used to set the data transmission rate between host computer and the inverter. Please
note that baud rate of the host computer and inverter must be the same. Otherwise, the communication is
impossible. The bigger baud rate is, the faster communication is.
Data Format
Pd-01
Factory Setting
0
0:No check: Data format <8,N,2>
1:Even parity Check :data format <8,E,1>
2:Odd Parity Check : data format <8,O,1>
3:No check: Data format <8-N-1>
Setting range
The setting data format of host computer and inverter must be the same; otherwise, the communication is
impossible.
Local Address
Pd-02
Factory Setting
Setting range
1
1~247, 0 is broadcast address
When the local address is set to be 0, that is broadcast address, it can realize the broadcast function of
host computer.
Local address must be unique (except broadcast address). This is the base of point-to-point
communication between host computer and inverter.
Response Delay
Pd-03
Factory Setting
Setting range
2ms
0~20ms
Response delay: It refers to the interval time from the inverter finishes receiving data to sending data to the
host computer. If the response delay is less than system processing time, then the response delay is
based on the system processing time. If the response delay is more than system processing time, after the
system processing the data, it should be delayed to wait until the response delay time arrives, then sending
data to host computer.
Communication Timeout
Pd-04
Factory Setting
0.0s (invalid)
0.1~60.0s
Setting range
173
0.0s
KE300 Inverter
MODBUS Communication Protocol
When the function code set to be 0.0 s, the communication timeout parameter is invalid.
When the function code set to be valid value, if the interval time between the communication and the next
communication is beyond the communication timeout, the system will report communication failure error
(Err16). At normal circumstances, it is set to be invalid. If in the continuous communication system, set the
parameter, you can monitor the communication status.
Communication Protocol selection
Pd-05
Factory Setting
1
0:Nonstandard Modbus protocol
1:Standard Modbus protocol
Setting range
PD-05=1: Select standard MODBUS protocol
PD-05=0: When reading the command, the slave return is one byte than the standard MODBUS protocol’s,
for details refer to communications Data Structure of this protocol.
Communication Read Current
Resolution
Pd-06
Factory Setting
0:0.01A
1:0.1A
Setting range
It is used to confirm the output current unit when communication reads output current.
