 Chapter 1 Safety and Attentions

1.2 Use Considerations

1.2.1 Motor Insulation Inspection

Chapter 1
When the motor is used for the first time or when the motor is reused after being
kept, or when periodical inspection is performed, insulation inspection shall be
conducted with motor 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 mega meter, and the insulating resistance measured shall be 5MΩ at least.

1.2.2 Motor Thermal Protection

If the motor rating does not match that of the inverter, especially when the rated
power of the inverter is higher than that of the motor, adjust motor protection
parameters in the inverter or install thermal relay to protect motor.

1.2.3 Operating with the Frequency Higher than Grid Power Frequency
Output frequency of is 0.00Hz~500Hz. If product is required to operate above
50.00Hz, please take the endurance of mechanical devices into consideration.

1.2.4 Mechanical Vibrations

Inverter may encounter mechanical resonance point of the load device at certain
output frequencies which can be avoided by setting the skip frequency paramet-
ers of the inverter.

1.2.5 Motor Heat and Noise

Since output voltage of inverter is PWM wave and contains a certain amount of
harmonics, so that the temperature, noise and vibration of the motor will be
higher than those when the inverter runs at grid power frequency.

1.2.6 Voltage-sensitive device or capacitor on output side of the AC drive

Do not install the capacitor for improving power factor or lightning protection
voltage-sensitive resistor on the output side of the AC drive because the output
of the AC drive is PWM wave. Otherwise, the AC drive may suffer transient
overcurrent or even be damaged.

1.2.7 Contactor at the I/O terminal of the AC drive

When a contactor is installed between the input side of the AC drive and the pow-
er supply, the AC drive must not be started or stopped by switching the contactor
on or off. If the AC drive has to be operated by the contactor, ensure that the time
interval between switching is at least one hour since frequent charge and discha-
rge will shorten the service life of the capacitor inside the AC drive;

-9-
 Chapter 1 Safety and Attentions

When a contactor is installed between the output side of the AC drive and the
motor, do not turn off the contactor when the AC drive is active. Otherwise,
Chapter 1

modules inside the AC drive may be damaged.

1.2.8 Applied with the Rated Voltage

Apply product with the rated voltage. Failure to comply will damage inverter. If
required, take a transformer to boost or step-down voltage.

1.2.9 Do Not Apply a 3-Phase Input Inverter to 2-Phase Input Applications

Do not apply a 3-phase input FR inverter to 2-phase input applications. Otherwise,
it will result in faults or damage inverter.

1.2.10 Lightning Protection

The product has integrated lightning over-current protection device which has
certain self-protection capacity against the lightning. Additional protection devices
have to be installed between inverter and power supply in the area where lightning
occurs frequently.

1.2.11 Altitude De-rating

In places where the altitude is above 1000 m and the cooling effect reduces due
to thin air, it is necessary to de-rate the AC drive. Contact Our company for
technical support.

1.2.12 Adaptable Motor

Standard adaptive motor is quadrupole squirrel- cage asynchronous induction
motor. If it is not above- mentioned motor, please select AC drive upon rated
current of moter. If you need to drive permanent magnet synchronous motor,
please consult our company;
The cooling fan of non variable frequency motor and rotor spindle are coaxially
connected. While despinning, the fan cooling effect also declines at the same
time.Hence, for overheated occasion of moter, you shall install strong exhaust
fan or change variable frequency motor;
AC drives have built- in adaptive motor standard parameters. It is necessary to
make motor parameter identification or amend default values to accord with
actual values, or it will influence operation effects and protective values;
As short circuit existing inside cable or motor will cause inverter alarming,
enen explosion. Therefore, please make insulation short- circuit test of initial
installed motor and cable first. And the test also is necessary in routine
maintenance.

3.1 Mechanical Installation

3.1.1 Installation Environment
Ø Environment temperature: Surrounding environment temperature has a gre-
at impact on lifetime of AC drive, and the operation environment temperat-
ure of AC drive shall not exceed allowable temperature range (- 10℃～ 40℃).
Ø
While AC drive is installed on the surface of inflaming retardants, and enough
space around is necessary for heat dissipation. When AC drive works, it will
produce plenty of heats. And make vertical installation onto supporting holder
with screw.
Chapter 3

Ø
Please install it in some places that are not easy to vibrate. And the vibra-
tion shall not be larger than 0. 6G. Especially pay attention to keep away from
punching machine and other equipments.
Ø
Avoid to be installed where there are direct sunlights, moist surroundings
and water drops.
Ø
Avoid to be installed where there are corrosivity, inflammability and explosive
gas.
Ø
Avoid to be installed where there are oil contamination, dirts and metal dusts.

 Chapter 3 Installation

3.1.3 The installation of the model needs to pay attention to the problem of heat
dissipation. So please note the following:

Ø
Please install the inverter vertically so that the heat can be dissipated upwar-
ds. But not upside down. If there are many inverters in the cabinet, it is better
to install them side by side. In the occasions that need to be installed up and
down, please refer to Figure 3-1 to install the heat insulation deflector.

Ø
The installation space is as shown in Figure 3-1 to ensure the cooling space
of the inverter. However, please consider the heat dissipation of other comp-

Chapter 3
onents in the cabinet when arranging.

Ø
The mounting bracket must be made of flame retardant material.

Ø
For applications with metal dust, it is recommended to install the radiator out-
side the cabinet. At this time, the space in the fully sealed cabinet should be
as large as possible.

3.4.2 Wiring Precautions

DANGER

Ø
Confirm power switch stays in the state of OFF and then start wiring
operation or it will give rise to electric shock hazard!

Ø
Wiring personnel must be those professional trainees or it will cause
equipment damages and personal injuries!

Ø
Reliable ground connection is necessary or it will give rise to electric
shock or fire alarm!

Ø
Confirm the input power is in accordance with the rated value of AC
drive, or it will cause damages to AC drive!

Ø
Confirm motor is adaptive with AC drive or it will cause damages to
motor or cause AC drive protection!

Ø
Power supply shall not be connected to the terminals of U, V and W, or
it will cause damages to AC drive!

Ø
Brake resistance shall not be connected directly to DC bus + 2 , - or it
will cause damages to AC drive!

 Chapter 3 Installation

3.4.3 Attentions of wiring

A.Input power L, N or R, S and T:
The connection of inverter input side has no phase sequence requirements.

B.DC bus + 2 , - terminals:

At the moment of power failure,DC bus + 2 , - terminals still have residual volta-
ge, you just can touch it after internal“charge” power light is off confirming the
voltage is less than 36V, it may cause electric shock.
When you select external brake unit for AC drive ≥30KW, the polarity of + 2 and -

Chapter 3
cannot be connected inversely or it will cause damages to ACdrive, or even fire
hazard.
The wiring length of brake unit shall not be more than 10m, and only twisted pair or
tight double-line is available in parallel.
Brake resistance cannot be connected onto DC bus directly, or it may cause damag-
es to AC drive, or even fire hazard.

C.Brake resistance connection terminal (+) and PB:

AC drive ≤22KW and built- in brake unit.
The recommended value of brake resistance model selection reference and wiring
distance shall be less than 5m, or it may cause damages to AC drive.

D.AC drive output side U, V and W:

AC drive output side shall not be connected to capacitor or surge absorber, or it
will frequent protection of AC drive, or even damages.
When the cable of motor is overlong, the effects of distributed capacitance will
generate electric resonance easily, and give rise to dielectric breakdown of motor.
The generated large leakage current makes AC drive suffer overcurrent protection. If
cable length is more than 100m,alternating current output reactor shall be installed.

E.Grounding terminal :
Terminals must have been reliable ground connection,and resistance value ofground
wire shall be less than 4Ω ,or it will cause abnormal work of equipment,and even
damages.
Grounding terminal and null line N terminal of power supply cannot be shared.

3.5.3 Signal input terminal wiring instructions:

A. AI analog input terminal:
Because weak analog voltage signals are particularly susceptible to external interfer-
ence, shielded cables are generally required, and the wiring distance should be as
short as possible, not exceeding 20m, as shown in Figure 3-5. In some occasions
where the analog signal is severely interfered, a filter capacitor or a ferrite core should
be added on the analog signal source side.

C. Y1 digital output terminal:

When the digital output terminal needs to drive the relay, an absorption diode should
be installed on both sides of the relay coil, and the driving capacity is not more than
50mA. Otherwise, it is easy to cause damage to the DC 24V power supply.
Note: The polarity of the absorption diode must be installed correctly, as shown in
Figure 3-14, otherwise when the digital output terminal has output, the DC 24V power
supply will be burned out immediately.

3.6 Treatment of EMC problem
3.6.1 Effects of harmonic wave

Ø
Higher harmonic wave of power supply will cause damages to inverter. So in
some places with bad power grid quality, we advise to install AC input reactor.

Ø
As higher harmonic wave exists at the output side of AC drive, the application
of capacitor to improve power factor and surge suppressor at output side may
lead to electric shock, or even damages to equipment, so capacitor or surge
suppression device cannot be installed at output side.

3.6.2 Electromagnetic interference and treatment

Œ
Electromagnetic interference has two categories: One is peripheral electrom-
agnetic noise’s interference on AC drive, which will give rise to false operatio-
ns of inverter itself. But the effects of such interference usually are small, be-
cause AC drive has been processed internally in design about this interfere-
nce, and it has a strong antiinterference capability. The other one is AC drive-
’s effects on peripheral equipments.

Ø
AC drive and other electrical products should ground well, and the ground
resistance shall not more than 4Ω.

Ø
It will be better if power line of AC drive won’t be placed in parallel with
circuit of control line. If condition permission, please arrange power lines
vertically.

Ø
At those occasions with a high anti- interference requirement, shield
cable shall be used between AC drive and power line of motor, and relia-
ble ground connection also is necessary for shielding layer.

-41-
 Chapter 3 Installation


Handling methods of interference from peripheral electromagnetic equipment
on AC drive.Electromagnetic effects on inverter generally result from the inst-
allation of many relays, contactors or electromagnetic contactors near AC
drive. When AC drive has false operation from the interference, please try to
solve it with following methods:

Ø
Install surge suppressor on the devices that make interference;

Ø
Install filter at signal input terminal of AC drive;
Chapter 3

Ø
The leading wire of AC drive’s control signal line and detection circuit sh-
all be shield cable, and reliable ground connection also is necessary for
shielding layer.

Ž
The handling methods of interference on peripheral equipments from the noi-
ses of AC drive:
This part of noise can be divided into two categories: One is the radiation of
AC drive itself, and the other one is the radiation of the leading wire from inv-
erterto motor.
These two kinds of radiations make the leading wires surface of peripheral
electrical equipments suffer electromagnetic and electrostatic induction,
which will lead to false operations of equipments. About these several differ-
ent disturbed conditions, please refer to following methods to resolve them:
Ø
Instrument, receiver, sensor and other equipment for measurement,gen-
erally have a weaker signal. If they are placed near AC drive or in a same
control cabinet, they will suffer interference and operate falsely. So we
advise to take following methods: Keep away from interference source;
Signal line shall not be placed with power line in parallel, especially shall
not be tied up together in parallel, and please adopt shield cable signal
line and power line;Install linear filter or radio noise filter at the input and
output sides of AC drive.

Ø
When interrupted equipments and AC drive share a same power supply, if
above methods still cannot help to eliminate interference, you shall install
linear filter or radio noise filter between AC drive and power supply.

-42-
 Chapter 3 Installation

Ø
Separated ground connection for peripheral equipments can help to elimi-
nate the interference from ground wires’leakage current of AC drive while
common grounding.

3.6.3 Leakage current and treatment

Leakage current has two categories when inverter is in service: One is leaka-
ge current over the ground: and the other is leakage current between lines.

Œ
The factors of influencing leakage current over the ground and solutions:

Chapter 3
Distributed capacitances exist between wire and ground. The larger distribu-
ted capacitances are, the larger the leakage current will be: Effectively decr-
easing the distance between AC drive and motor can reduce distributed cap-
acitances. The larger carrier frequency is, the larger the leakage current will
be. Reducing carrier frequency can decrease leakage current effectively. But
reducing carrier frequency will result in the increase of motor noise, so pleas-
e note this. Installing electric reactor also is an effective method to solve lea-
kage current.
Leakage current will increase with enlargement of loop current,so when the
power of motor is large, the relevant leakage current also will be large.


The factors of influencing electric current between lines and solutions:
Distributed capacitances exit between output wires of AC drive. If the electric
current passing the circuit contains higher harmonic, it may give rise to reso-
nance and leakage current. If you use thermal relay, it may cause false ope-
ration at this time.
The solution is to decrease carrier frequency or install output reactor. We
advise not to install thermal relay before you use the motor of AC drive, but
apply the electronic overcurrent protection function of AC drive.

The KD600 inverter provides a variety of terminal control modes. The terminal co-
mmand mode is determined by the function code P5-11, and the input port of the
start-stop control signal is determined by the function code P5-00~P5-04. For the
specific setting method, please refer to the detailed explanation of function codes
such as P5-11, P5-00～P5-04.

In the above figure, the function code of communication timeout time (P8-04) is set
to a value other than 0, that is, the function of automatic shutdown of the inverter
after the communication timeout fault is activated, which can avoid the failure of
the communication line or the failure of the host computer. The frequency conver-
ter is running uncontrolled. This feature can be turned on in some applications.

The MODBUS-RTU slave protocol is built into the communication port of the inver-
ter, and the host computer must use the MODBUS-RTU master protocol to comm-
unicate with it. For the specific communication protocol definition, please refer to
Appendix A: KD600 Modbus Communication Protocol of this manual.

4.6.2 Start mode

Chapter 4
There are 3 start modes of the inverter, namely direct start, speed tracking start
and asynchronous motor pre-excitation start, which are selected by function par-
ameter P1-00.

P1-00=0, direct start mode, suitable for most small inertia loads, the frequency
curve of the start process is as shown in the figure below. The "DC braking" func-
tion before starting is suitable for the drive of elevators and heavy loads; the "sta-
rting frequency" is suitable for the drive of equipment that needs starting torque
shock start, such as cement mixer equipment.

4.7 Frequency converter operating frequency control

The inverter is set with 2 frequency given channels, named as main frequency so-
urce X and auxiliary frequency source Y respectively. They can work with a single
channel or can be switched at any time, and can even set the calculation method
for superposition and combination to meet the needs of the application site.
Different control requirements.

4.7.1 Main frequency given source selection

There are 9 main frequency sources of the inverter, which are digital setting
(UP/DN power-off memory), digital setting (UP/DN power-off memory), AI1, AI2,
PULSE input, multi-segment instruction, simple PLC, PID , communication given,
etc., you can choose one of them by setting P0-06.

It can be seen from the different frequency sources in the figure that the operating
frequency of the inverter can be determined by the function code, it can also be
adjusted manually in real time, it can also be given by the analog quantity, and it
can also be given by the multi-speed terminal command. It can be closed-loop
regulated by the built-in PID regulator through the external feedback signal; it can
also be controlled by the host computer communication.

4.7.4 Wobble frequency working mode setting

In textile and chemical fiber processing equipment, using the swing frequency fu-
nction can improve the evenness and density of the spindle winding, as shown in
the figure below. It can be realized by setting the function codes from Pb-00 to Pb-

4.7.5 Multi-speed mode settings

For applications that do not need to continuously adjust the operating frequency
of the inverter, but only need to use several frequency values, when multi-speed
control can be used, the KD600 can set up to 16 operating frequencies, which can
be selected by the combination of 4 DI input signals. Set the function code corre-
sponding to the DI port to the function value of 12 to 15, that is to say, it is design-
ated as the multi-segment frequency command input port, and the required multi-
segment frequency is set by the multi-segment frequency table of the PC group.
Specify as multi-segment frequency given mode, as shown in the following figure:

Chapter 4

In the figure above, DI2, DI3, DI4, and DI5 are selected as the signal input termin-
als for multi-segment frequency designation, and 4-bit binary numbers are formed
from them in turn, and the multi-segment frequency is selected by combining the
values according to the state. When (DI5, DI4, DI3, DI2) = (0, 0, 1, 0), the number
of state combinations formed is 2, and the frequency set by the PC-02 function
code will be selected as the target operating frequency.

KD600 can set up to 4 DI ports as multi-segment frequency command input term-

inals, and also allow less than 4 DI ports to perform multi-segment frequency set-
ting. For the missing setting bits, it is always calculated as state 0.

4.7.6 Motor running direction setting

After the inverter restores the factory parameters, press the "RUN" key, the invert-
er drives the motor's direction, which is called the forward direction. If the rotation
direction at this time is opposite to the direction required by the equipment, please
set P0-13=1 or power off. After that (pay attention to the discharge of the main
capacitor charge of the inverter), replace any two wirings in the UVW output line
of the inverter to eliminate the problem of the rotation direction.

In some drive systems, only the system is allowed to run in the forward direction
and not in the reverse direction, you need to set P0-13 = 2. If there is a reverse
command at this time, the inverter will decelerate to 0 and enter the stop state,
and at the same time FWD/REV keeps flashing on the operation panel. The logic
shown in the figure below.

For applications that do not allow motor reversal, please do not use the method of
modifying the function code to change the direction, because the above two func-
tion codes will be reset after restoring the factory defaults. At this time, the functi-
on of No. 50 of the digital input terminal DI can be used to prohibit reverse rotation.

4.7.7 Fixed-length control mode settings

KD600 has a fixed-length control function. The length pulse is collected through
the DI (DI function selection is 30) terminal. The number of pulses sampled by the
terminal is divided by the number of pulses per meter Pb-07, and the actual length
Pb-06 can be calculated. When the actual length is greater than the set length Pb-
05, the multi-function digital switch output "length reached" ON signal.

During the fixed-length control process, the length reset operation can be perfor-
med through the multi-function DI terminal (the DI function selection is 31), and
the specific settings are shown in the following figure.

4.7.8 How to use the inverter count function

The count value needs to be collected through the DI (DI function selection is 28)
terminal. When the count value reaches the set count value Pb-08, the multi-func-
tion digital switch output "set count value reached" ON signal, and then the counter
stops counting.

When the count value reaches the designated count value Pb-09, the multi-func-
tion digital switch value outputs the "designated count value reached" ON signal,
and the counter continues to count at this time, and the counter stops until the "set

4.8 Motor characteristic parameter setting and automatic tuning

4.8.1 Motor parameters to be set
When the inverter runs in the "vector control" (P0-03=1) mode, it has a strong de-
pendence on the accurate motor parameters, which is one of the important differ-
ences from the "VF control" (P0-03=2) mode. In order for the inverter to have good
drive performance and operating efficiency, the inverter must obtain the accurate
parameters of the controlled motor.

The required motor parameters are (default motor 1 function code):

 Chapter 4 Operation and Display

The steps of automatic tuning of motor parameters are as follows:

The following takes the parameter identification method of default motor 1 as an

example to explain, and the identification method of motor 2 is the same.
Step 1:
If the motor can be completely disconnected from the load, in the case of power
failure, mechanically disconnect the motor from the load part, so that the motor
can rotate freely without load.
Step 2:
After power-on, first select the inverter command source (P0-04) as the operation
panel command channel.

Chapter 4
Step 3:
Input the nameplate parameters of the motor accurately (such as P4-01~P4-06),
please input the following parameters according to the actual parameters of the
motor (selected according to the current motor):

Motor selection Parameters

P4-01: Motor rated power P4-02: Motor rated voltage

Motor 1 P4-04: Motor rated current P4-05: Motor rated frequency
P4-06: Motor rated speed

Motor 2 A1-01 to A1-06: Same as above definition

Step 4:
If it is an asynchronous motor, please select 2 (dynamic full tuning) for P4-00
(tuning selection, for motor 2, it corresponds to A1-00 function code), and press
ENTER to confirm. At this time, the keyboard displays:

Then press the RUN key on the keyboard panel, the inverter will drive the motor to
accelerate and decelerate, run forward and reverse, the running indicator lights
up, and the identification running lasts about 2 minutes. When the above display
information disappears, it returns to the normal parameter display state, indicating
that the tuning is completed. . After this complete tuning, the frequency converter
automatically calculates the following parameters for the motor:

Motor 2 A1-07 ~ A1-11: Same as above

If the motor cannot be completely disconnected from the load, select 1 (static tun-
ing) for P4-00 (motor 2 is P1-00), and then press the RUN key on the keyboard
panel to start the motor parameter identification operation.

4.9 How to use the DI port of the inverter

The control board comes with 5 DI ports, numbered DI1~DI5. The internal hardw-
are of the DI port is equipped with a 24Vdc power supply for detection. Users only
need to short-circuit the DI port and the COM port to input the DI signal to the
inverter.

-72-
 Chapter 4 Operation and Display

In the factory default state, P5-13=00000, when the DI port is short-circuited, it is a

valid (logic 1) signal; when the DI port is floating, the DI is an invalid (logic 0) sign-
al; the user can also change the DI port's signal Valid mode, that is, when the DI
port is short-circuited, it is an invalid (logic 0) signal; when the DI port is floating,
the DI is a valid (logic 1) signal. At this time, it is necessary to modify the correspo-
nding bit of P5-13 to 1. , the two function codes correspond to the valid mode setti-
ngs of DI1~DI5 respectively.

The inverter also sets a software filter time (P5-10) for the input signal of the DI
port, which can improve the anti-interference level. For the DI1~DI3 input ports,
the port signal delay function is also provided, which is convenient for some appli-
cations that require delay processing:

Chapter 4
T T

Figure 4-27 DI delay settings

The functions of the above five DI ports can be defined in the function codes of P5-
00~P5-04, and each DI can be selected from 53 functions according to requirem-
ents. For details, please refer to the detailed description of P5-00~P5-04 function
codes.

In the design of hardware features, only HDI can accept high-frequency pulse sig-
nals. For applications that require high-speed pulse counting, please arrange it on
the HDI port.

4.10 How to use the DO port of the inverter

The control board comes with 2 digital outputs, which are the control board relays
RELAY1 and Y1, of which Y1 is a transistor output, which can drive a 24Vdc low-
voltage signal circuit; the relay output can drive a 50Vac control circuit.

 Chapter 4 Operation and Display

By setting the value of function parameters P6-00 to P6-02, various digital output
functions can be defined, which can be used to indicate various working states

4.13 How to use inverter serial communication

See the P8 group function for the hardware communication parameter configurati-
on of the communication port. Setting the communication rate and data format to
be consistent with the host computer is the premise for normal communication.

The serial port of KD600 has a built-in MODBUS-RTU slave communication prot-
ocol. The host computer can query or modify the inverter function code, various
running status parameters, and send running commands and operating frequenc-
ies to the inverter through the serial port.

Communication settings should be

consistent with the host computer settings

The internal information of function codes, various operating status parameters,

various operating instructions and other information in KD600 is organized in the
way of "register parameter address".

For more details, please refer to Appendix A: KD600 Modbus Communication

Protocol.

4.14 Password setting

The inverter provides the user password protection function. When P7-49 is set to
non-zero, it is the user password. After returning to the status parameter interface,
the password protection will take effect. At this time, press the PRG key, it will dis-
play "-----", only the status parameters are displayed, you must press the key on
the "-----" interface, and the panel displays "00000", after entering the user passw-
ord correctly, you can enter the normal menu to check and set the function code,
otherwise the panel will display "-----" and the function code cannot be entered.

If you want to cancel the password protection function, you can only enter through
the password according to the above steps, and set P7-49 to 0.

 Chapter 6 Description of Function Codes

The set frequency value of the inverter can be changed through the increase and decrease
keys of the keyboard (or the UP and DOWN of the multi-function input terminal).
Power-off means that when the inverter is powered on again after power-off, the set frequen-
cy is the set frequency before the last power-off.
2: AI1
3: AI2
It means that the frequency is determined by the analog input terminal. KD600 control board
provides 2 analog input terminals (AI1, AI2)
Among them: AI1 is 0V~10V voltage input, AI2 can be 0V~10V voltage input, or 0mA~20mA
current input, which is selected by the dial switch on the control board.
The input voltage value of AI1, AI2, and the corresponding relationship curve of the target
frequency, the user can freely choose through P5-45.
KD600 provides 4 sets of corresponding relationship curves, of which 2 sets of curves are
straight-line relationships (2-point correspondence), and 2 sets of curves are arbitrary curves
with 4-point correspondence. Users can use P5-15~P5-24 function codes and PE group code
to set.
Function code P5-45 is used to set the two analog inputs of AI1~AI2, and select which group
of the 4 groups of curves respectively.
When AI is used as a given frequency, the voltage/current input corresponds to 100.0% of the

Select Simple PLC mode. When the frequency source is a simple PLC, it is necessary to set
the PC group "multi-speed and PLC" parameters to determine the given frequency.
6: PID
Select Process PID Control. At this time, it is necessary to set the PA group "PID function".
The operating frequency of the inverter is the frequency value after PID action. For the

When the auxiliary frequency source is used as an independent frequency reference chann-
el, its usage is the same as that of the main frequency source X.
When the auxiliary frequency source is used as the superposition reference (the one digit of
P0-10 is 1, 2, 3, 4), it has the following special features:
1. When the auxiliary frequency source is a digital reference, the preset frequency (P0-11)
does not work. It can be performed on the basis of the main reference frequency through the
increase and decrease keys of the keyboard (or UP and DOWN of the multi-function input
terminal). Adjust up and down.
2. When the auxiliary frequency source is given by analog input (AI1, Ai2), 100% of the input
setting corresponds to the range of auxiliary frequency source (see the description of P0-08
and P0-09). If you need to adjust up and down on the basis of the main given frequency, ple-
ase set the corresponding setting range of the analog input to -n% to +n% (refer to the
description of P5-15 to P5-24).
Tip: The auxiliary frequency source Y selection cannot be the same as the main frequency

determined

This function adjusts the carrier frequency of the inverter. By adjusting the carrier frequency,
the motor noise can be reduced, the resonance point of the mechanical system can be avo-
ided, the line-to-ground leakage current can be reduced, and the interference generated by
the inverter can be reduced.
When the carrier frequency is low, the higher harmonic components of the output current inc-
rease, the loss of the motor increases, and the temperature rise of the motor increases.
When the carrier frequency is high, the motor loss decreases and the motor temperature rise
decreases, but the inverter loss increases, the inverter temperature rise increases, and the
interference increases.
Adjusting the carrier frequency affects the following performance:

Motor noise Leakage current

Carrier frequency Low → High
Motor noise Big → Small
Output current waveform Bad → Good
Chapter 6

Motor temperature rise High → Low

Inverter temperature rise Low → High
Leakage current Small → Large
External Radiation Interference Small → Large

The factory setting of carrier frequency is different for inverters of different power. Although
the user can modify it according to the needs, it should be noted that if the carrier frequency
is set higher than the factory value, the temperature rise of the inverter radiator will increase.
At this time, the user needs to derate the inverter, otherwise the inverter will be in danger of
overheating alarm .

In order to compensate the low frequency torque characteristic of V/F control, some boost
compensation is made to the output voltage of the inverter at low frequency.
If the torque boost setting is too large, the motor is easily overheated, and the inverter is pro-
ne to overcurrent. Generally, the torque boost should not exceed 8.0%.
Effective adjustment of this parameter can effectively avoid overcurrent during startup. For
larger loads, it is recommended to increase this parameter, and when the load is light, this
parameter setting can be reduced. When the torque boost is set to 0.0, the inverter is
automatic torque boost.

and if it exceeds this set frequency, the torque boost becomes invalid. See Figure 5-4 for

If the factory parameters can not meet the requirements, fine-tune on the basis of the factory
default parameters, first increase the proportional gain to ensure that the system does not
oscillate; then reduce the integral time, so that the system has faster response characteristics
and less overshoot.
Note: If the PI parameter is not set properly, it may cause the speed overshoot to be too larg-

P3-23 Braking torque upper limit 0.0～200.0% 150.0% ☆

This parameter is used to set the upper limit of braking torque of the inverter. This parameter
is used to set the upper limit value of the motor torque of the inverter. When the actual directi-
on of the motor is the same as the direction of the torque, it is electric, otherwise it is braking.
When the electric torque and braking torque need different setting values, they can be set
separately through P3-21 and P3-23.
For example, in the case of cam load, due to the periodic change of the electric and braking
states, at this time, by appropriately reducing the upper limit of the braking torque P3-23, the
rise of the inverter bus voltage can be effectively reduced without affecting the normal operat-
ion of the driving load.

In order to ensure the dynamic control performance of the inverter, please select rotary tunin-
g. During rotary tuning, the motor must be disconnected from the load (no load).
After selecting rotary tuning, the inverter will perform static tuning first. After the static tuning
is completed, the motor will follow the acceleration set by P4-12.
Accelerate to 80% of the rated frequency of the motor, keep it for a period of time, and then
decelerate to zero speed according to the deceleration set by P4-13, and the rotation tuning
is over.

In order to effectively protect the overload of different motors, it is necessary to set P9-01 ap-
propriately. For the usage method, refer to Figure 5-21 of the inverse time limit curve of motor
overload protection. In the figure, L1 is the relationship between the motor protection time
and the motor current when P9-01=1. When the user needs to change the protection time of
a certain current of the motor, he only needs to change P9-01. The time relationship is:
Chapter 6

Required protection time T = P9-01 × T(L1)

Example:
When the user needs to modify the protection time of 150% rated current to 3 minutes, first
find in Figure 5-20 that the protection time of 150% motor current is 6.0 minutes, then P9-01
= required protection time T/T (L1)=3min/6min=0.5.
The maximum time of motor overload protection is 100 minutes, and the shortest overload
time is 0.1 minutes. Please set it according to your needs. And when the motor is overloaded,
the inverter will report Err14 to avoid damage to the motor due to continuous heating.

le and the target signal, and by adjusting the output frequency of the inverter, a closed-loop
system is formed, so that the controlled variable is stable at target value.
It is suitable for process control occasions such as flow control, pressure control and temper-
ature control. Figure 5-23 is the control principle block diagram of process PID.

vely through the keyboard display parameters.

In some applications, a set of PID parameters cannot meet the needs of the entire operation
process, and different PID parameters need to be used in different situations. This group of
function codes is used for switching between two groups of PID parameters. Among them,
the setting method of the regulator parameters PA-18~PA-20 is similar to the parameters
PA-06~PA-08. PA-21 is the PID parameter switching condition:
PA-21=0: do not switch, use the first group of PID parameters.
PA-21=1: DI terminal switching, multi-function terminal function selection should be set to 43
(PID parameter switching terminal), when the terminal is invalid, select parameter group 1
(PA-06~PA-08), when the terminal is valid, select the parameter Group 2 (PA-18~PA-20).
PA-21=2 Automatically switch according to the deviation. When the absolute value of the
deviation between the reference and the feedback is less than the PID parameter switching
deviation 1 (PA-22), the PID parameter selects parameter group 1. When the absolute value
of deviation between reference and feedback is greater than PID switching deviation 2 (PA-
23), PID parameter selection selects parameter group 2. When the deviation between
reference and feedback is between switching deviation 1 and switching deviation 2, the PID
parameters are the linear interpolation values of two sets of PID parameters, as shown in
Figure 6-24.

Group PD: Torque control

Torque control can be performed only when the control mode P0-03 is vector control, so that
the output torque of the motor is controlled by the torque command. When using torque cont-
rol, there are the following precautions:

Torque control takes effect

To make torque control effective, please set Pd-10 to 1, or set the multi-function DI terminal
function to 44 before use.
In addition, the torque control prohibition (function 32) can be realized through the multi-func-
tion digital DI terminal. When the torque prohibition function is valid, the inverter is fixed in
the speed control mode.

Setting of torque command and speed limit

The torque command can be set through Pd-00 and Pd-01. When the torque source is non-
digital setting, 100% input corresponds to the setting value of Pd-01.
The speed limit can be set digitally through Pd-03 and Pd-04, or through the upper limit freq-
uency P0-15, P0-16, P0-17.

Direction setting of torque command

During torque control, the direction of the torque command is related to the direction of the

Chapter 6
running command and the input torque value, as shown in the following table:

Enter torque value Torque command

Run command
(calculated percentage) direction
Forward >0 Forward direction

Forward <0 Reverse direction

Reverse >0 Forward direction

Reverse <0 Reverse direction

Switching between speed and torque modes

When the multi-function digital DI terminal is set with speed control/torque control switching
(function 44), when the speed control/torque control switching function of the corresponding
terminal is valid, the control mode is equivalent to the inversion of the value of Pd-10;
otherwise The control mode is determined by Pd-10.

0: Digital setting (Pd-01), which means that the target torque directly uses the setting
value of Pd-01.
1: AI1
2: AI2
It means that the target torque is determined by the analog input terminal. The KD600 control
board provides 2 analog input terminals (AI1, Ai2), of which AI1 is 0V~10V voltage input, AI2
can be 0V~10V voltage input, or 0mA~20mA current input, which is selected by the DIP swi-
tch on the control board. The input voltage value of AI1, AI2, and the corresponding relation-
ship curve of the target torque, the user can freely choose through P5-45.
KD600 provides 4 sets of corresponding relationship curves, of which 2 sets of curves are
straight-line relationships (2-point correspondence), and 2 sets of curves are arbitrary curves
with 4-point correspondences. code to set.
Function code P5-45 is used to set the two analog inputs of AI1~AI2, and select which group
of the 4 groups of curves respectively.

4: PULSE pulse (HDI)
The target torque is given by the terminal HDI high-speed pulse.
Pulse given signal specifications: voltage range 9V ~ 30V, frequency range 0kHz ~ 50kHz.
Pulse given can only be input from the multi-function input terminal HDI.
The relationship between the input pulse frequency of the HDI terminal and the correspond-
ing setting is set through P5-30~P5-34. The corresponding relationship is a straight line co-
rresponding relationship between 2 points. The 100.0% set corresponding to the pulse input
refers to the relative torque figure. Set the percentage of PD-01.

The above function code defines the relationship between the analog input voltage and the
set value represented by the analog input. When the analog input voltage exceeds the set
maximum input or minimum input range, the other part will be calculated as the maximum
input or minimum input.
When the analog input is current input, 1mA current is equivalent to 0.5V voltage.
The curve 1 and curve 2 are the same as the analog input quantization of the P5 group, but
the analog quantization of the P5 group is linear and the PE group curve can be set to the
curve type, so the analog input multi-point curve can be used more flexibly. The schematic

Chapter 6

The analog input AI1～AI2 of KD600 all have the function of setting value jumping.
The jump function means that when the corresponding setting of the analog quantity chang-
es between the upper and lower intervals of the jump point, the corresponding setting value
of the analog quantity is fixed to the value of the jump point.
For example: the voltage of the analog input AI1 fluctuates around 5.00V, the fluctuation ran-
ge is 4.90V~5.10V, the minimum input of AI1 is 0.00V corresponds to 0.0%, and the maxim-
um input of 10.00V corresponds to 100.%, then the detected AI1 corresponds to the setting It
fluctuates between 49.0% and 51.0%. Set AI1 to set jump point PE-24 to 50.0%, set AI1 to
set jump amplitude PE-25 to 1.0%, then when the above AI1 input is processed by the jump
function, the corresponding setting of AI1 input is fixed to 50.0%. AI1 is transformed into a
stable input, eliminating fluctuations.

ence of the zero offset and linearity of the AI input port. This group of functional parameters
has been calibrated before leaving the factory, and the user can calibrate it again according
to the on-site usage, but the parameters will be restored together when restoring the factory
defaults. Calibration is generally not required at the application site.
The measured voltage refers to the actual voltage measured by a multimeter and other mea-
suring instruments, and the displayed voltage refers to the displayed voltage value sampled
by the inverter. The displayed voltages of AI1 and AI2 correspond to function codes U1-19
and U1-20 respectively.
When calibrating, input two voltage values to each AI input port, and respectively input the
value measured by the multimeter and the value read by the U0 group into the above functi-
on codes, then the inverter will automatically perform AI zero offset and calibration. Gain

During calibration, after inputting the target voltage and the measured voltage in the corres-
ponding function code, the inverter will automatically correct the output value.

Group B4: Master-slave control parameters

Master-slave control refers to the data exchange between two or more inverters through poi-
nt-to-point communication, so as to achieve the effect of speed synchronization or current
balance between multiple inverters, and is often used in multi-drive occasions. For example,
sand excavators, coal mine belt conveyors, etc. Please correctly set the inverter communica-
tion group P8 group before use.
When using 485 communication for master-slave control, the inverter can no longer commu-
nicate normally with the host computer using 485 communication, otherwise the system will
work abnormally. There are the following precautions when using master-slave control:

Master and slave directions are determined

When master-slave control and speed synchronous control is required, make sure that the
actual running directions of the master and slave motors are the same before running.

-231-
 Chapter 6 Description of Function Codes

When the master and slave directions are inconsistent, the actual running direction of the
motor can be changed by selecting P0-13 through the motor direction or changing the wiring
sequence between the motor and the output terminal of the inverter.

Master and slave control parameter setting

When multiple inverters are used to drive the same load, there are two control methods for
the master and slave:
1) The master control mode P0-03 is set to vector, and the slave is vector and torque control.
This method is used in most cases.
2) The master control mode P0-03 is set to VF, and the slave P0-03 is also set to VF. At this
time, please set the appropriate sag rate P7-18, please refer to P7-18 for the setting method.
Otherwise, the current between master and slave will be unbalanced;
3) When the mechanical transmission ratios of the master and slave are the same, the maxi-
mum frequency P0-14 of the master and slave inverters must be the same;
4) When the host B4-02=0, the acceleration and deceleration time of the slave should be set
to 0; when the host B4-02=1, the acceleration and deceleration time of the slave should be
consistent with the host;
5) There can only be one master in a system, but there can be multiple slaves. At the same
time, according to the communication method used, KD600 only supports 485 communicat-

Set P4-01~P4-06 according to the actual motor parameters.

7.2 Parameter identification

Œ
Connect the motor, if there is a load, set P4-00 to 1; if it is an empty shaft, set
P4-00 to 2, the digital tube will display TUNE, in order to ensure the control
effect, the motor is best to be no-load and set P4 -00 is 2.


Press the RUN key to perform parameter identification, and wait for TUNE to
disappear, then the parameter identification ends.

Ž
The identification process lasts for about 1 minute, and you can press the
STOP button in the middle to exit. During this period, current will be sent, run
the motor at the set acceleration and deceleration time to 60% of the rated
Chapter 7

frequency of the motor to observe whether the motor runs smoothly, if not,
press STOP to exit, reach 60% of the rated frequency of the motor, and dece-

7.3 No-load test run

Œ
Set the speed to a smaller range, such as P0-11= 20Hz.


Press the run key to check whether the motor can accelerate to the set frequ-
ency and whether the motor current is small. If the motor can accelerate to
the set frequency and the motor current is small, the inverter is basically no-
rmal. Set the frequency to the rated frequency of the motor and check wheth-
er the motor can accelerate to the set frequency.

 Chapter 8 EMC (Electromagnetic Compatibility)

8.1 Definition
Electromagnetic compatibility refers to the ability of electrical equipment to opera-
te in an electromagnetic interference environment without interfering with the ele-
ctromagnetic environment and to stably achieve its functions.

8.2 Introduction to EMC Standards

According to the requirements of the national standard GB/T12668.3, the inverter
needs to meet the requirements of electromagnetic interference and anti-electro-
magnetic interference.
Our existing products implement the latest international standard: IEC/EN61800-
3: 2004 (Adjustable speed electrical power drive systems part 3: EMC requirem-
ents and specific test methods), which is equivalent to the national standard GB/
T12668.3.
IEC/EN61800-3 mainly inspects the inverter from two aspects: electromagnetic
interference and anti-electromagnetic interference. Electromagnetic interference
mainly tests the radiated interference, conducted interference and harmonic inte-
rference of the inverter (for domestic inverters, there are requirements). The anti-
electromagnetic interference mainly affects the conducted immunity, radiation
immunity, surge immunity, rapid mutation pulse group immunity, ESD immunity
and low frequency end immunity of the power supply of the inverter (specific test
items are: 1 , Input voltage sag, interruption and change immunity test; 2. Com-
mutation notch immunity test; 3. Harmonic input immunity test; 4. Input frequency
change test; 5. Input voltage unbalance test; 6. Input voltage fluctuation test) to

test. Tested in accordance with the strict requirements of IEC/EN61800-3 above,

our products are installed and used in accordance with the instructions shown in
8.3, and will have good electromagnetic compatibility in general industrial envir-
onments.

8.3 EMC Guidance

8.3.1 Influence of harmonics:
High-order harmonics of the power supply will damage the inverter. Therefore, in
some places where the quality of the power grid is relatively poor, it is recomm-
ended to install an AC input reactor.

-248-
 Chapter 8 EMC (Electromagnetic Compatibility)

8.3.2 Electromagnetic Interference and Installation Precautions

There are two kinds of electromagnetic interference, one is the interference of the
electromagnetic noise in the surrounding environment to the inverter, and the ot-
her is the interference generated by the inverter to the surrounding equipment.
Installation Precautions:

Œ
The grounding wire of the inverter and other electrical products should be well
grounded;

The power input and output lines of the inverter and the weak current signal
lines (such as control lines) should not be arranged in parallel as far as poss-
ible, and should be arranged vertically if possible;
Ž
It is recommended to use shielded cables for the output power lines of the in-
verter, or use steel pipes to shield the power lines, and the shielding layer
should be grounded reliably. For the leads of the disturbed equipment, it is
recommended to use twisted-pair shielded control lines, and the shielding
layer should be reliably grounded;

For the motor cable whose length exceeds 100m, it is required to install an
output filter or reactor.

8.3.3 How to deal with the interference caused by peripheral electromagnetic

equipment to the inverter
Generally, the reason for the electromagnetic influence on the inverter is that a
large number of relays, contactors or electromagnetic brakes are installed near
the inverter. When the inverter is disturbed and malfunctions due to this, it is reco- Chapter 8
mmended to take the following solutions:

Œ
Nstall a surge suppressor on the device that generates interference;

Install a filter on the input end of the inverter, refer to 8.3.6 for details;
Ž

8.3.4 How to deal with the interference caused by the frequency converter to
the peripheral equipment

-249-
 Chapter 8 EMC (Electromagnetic Compatibility)

Œ
The noise in this part is divided into two types: one is the radiated interference
of the inverter, and the other is the conducted interference of the inverter.
These two kinds of interference make the surrounding electrical equipment
subject to electromagnetic or electrostatic induction. This in turn causes the
device to malfunction. For several different interference situations, refer to the
following solutions:

Instruments, receivers and sensors used for measurement generally have
weak signals. If they are close to the inverter or in the same control cabinet,
they are prone to interference and malfunction. It is recommended to use the
following solutions: try to Keep away from interference sources; do not arran-
ge signal lines and power lines in parallel, especially do not bundle them in
parallel; use shielded lines for signal lines and power lines, and the grounding
is good; add a ferrite magnetic ring to the output side of the inverter (select
the suppression frequency at 30~1000MHz range), and winding 2~3 turns in
the same direction, for bad conditions, you can choose to install an EMC ou-
tput filter;
Ž
When the interfered equipment and the inverter use the same power supply, it
will cause conduction interference. If the above methods cannot eliminate the
interference, an EMC filter should be installed between the inverter and the
power supply (refer to 7.3.6 for details). type operation);

The peripheral equipment is grounded separately, which can eliminate the int-
erference caused by the leakage current of the ground wire of the inverter
when the ground is shared.
Chapter 8

8.3.5 Leakage Current and Handling

There are two forms of leakage current when using the inverter: one is the leakage
current to the ground; the other is the leakage current between lines.
Factors affecting ground leakage current and solutions:

Œ
There is a distributed capacitance between the wire and the ground. The larg-
er the distributed capacitance, the larger the leakage current; effectively redu-
ce the distance between the inverter and the motor to reduce the distributed
capacitance. The greater the carrier frequency, the greater the leakage curr-
ent. The carrier frequency can be lowered to reduce leakage current.

-250-
 Chapter 8 EMC (Electromagnetic Compatibility)

However, reducing the carrier frequency will increase the motor noise. Please
note that adding a reactor is also an effective way to solve the leakage current.


Factors and solutions that cause leakage current between lines:
There is distributed capacitance between the output wiring of the inverter. If the
current passing through the wiring contains high-order harmonics, it may cause
resonance and cause leakage current. At this time, using a thermal relay may
cause it to malfunction.
The solution is to reduce the carrier frequency or install an output reactor. When
using the inverter, it is recommended not to install a thermal relay between the
inverter and the motor, and use the electronic overcurrent protection function of
the inverter.

8.3.6 Precautions for installing EMC input filter on power input

When installing an EMCS input filter at the power input end, pay attention to the
following:

Œ
When using the filter, please use it strictly according to the rated value; since
the filter is a Class I electrical appliance, the ground of the metal casing of the
filter should be in good contact with the metal ground of the installation cab-
inet in a large area, and good electrical continuity is required, otherwise there
will be electric shock Dangerous and seriously affect the EMC effect;

Through the EMC test, it is found that the filter ground must be connected to
the same common ground as the PE terminal of the inverter, otherwise the Chapter 8
EMC effect will be seriously affected;
Ž
Install the filter as close to the power input end of the inverter as possible;

The EMC input filter cannot be used at the output end of the inverter for
filtering.

9.1 Fault alarm and countermeasures

If a fault occurs during the system operation, the inverter will immediately protect
the motor to stop the output, and the corresponding inverter fault relay contact will
act. The inverter panel displays the fault code. The fault type and common soluti-
on corresponding to the fault code are shown in the following table. The list in the
table is for reference only, please do not repair or modify it without authorization.

9.3 Common faults of synchronous motors and their solutions

9.3.1 Motor starts with heavy load
If the motor does not start normally with load, you can try the following operations:

Œ
Increase the upper limit of torque current (P3-21)
When the load is greater than the torque output of the inverter, the inverter will be
in a locked-rotor state, and P3-21 can be appropriately increased at this time.


Increase the speed PI adjustment parameter, modify the resistance value or
static identification to correct the motor resistance.
The motor resistance parameter (P4-17) will significantly affect the load carrying
capacity of the motor at low speed. When the resistance parameter (P4-17) exc-
eeds the actual resistance value by too much (for example, 200% of the actual
resistance value), it may cause the motor to reverse at low speed at the upper
torque limit current. When the resistance parameter (P4-17) is too much lower
than the actual resistance value (for example, 50% of the actual resistance valu-
e), it may cause the motor to run in a step-by-step manner, or rotate for a period
of time and stop for a period of time. Increasing the speed P value P3-04 at low
speed and reducing the speed loop integral time P3-05 may improve the problem
caused by too small resistance parameters.

9.3.2 Adjust the speed loop PI parameters (under normal circumstances do not
need to adjust)
Œ
In general, if the proportional coefficient of speed PI adjustment is too large, it
will cause high-frequency vibration of the speed, and the mechanical vibration
or electromagnetic noise will increase significantly; if the proportional coeffici-
ent is too small and the integration time is too small or the load inertia is too
large, it will cause low-frequency vibration of the speed and overshoot of the
Chapter 9

speed. Obviously, if there is no discharge measures, there may be overvoltage.


If you need to adjust the speed PI parameter, first increase the integral time,
increase the ratio if the speed does not oscillate, and then decrease the integral
time if the effect is not satisfactory. Generally, the larger the inertia of the syste-
m, the smaller the integral time and the larger the proportional coefficient. If the
speed filter coefficient is increased, the integral time should be increased, and
the proportion can be increased appropriately.

-261-
 Chapter 9 Troubleshooting and Countermeasures

Note:
The inertia of the drive system is equal to the motor inertia plus the load inertia.
The inertia of the motor is proportional to the mass of the motor and the square of
the diameter of the motor; the inertia of the transmission load is proportional to the
mass of the load and the square of the diameter of the transmission wheel; if the-
re is a deceleration or speed-up device, the inertia is proportional to the speed-up
ratio and inversely proportional to the deceleration ratio .
For loads with large inertia, if fast speed response is required, the integration time
needs to be reduced, but it is easy to cause speed overshoot, resulting in overv-
oltage of the inverter, and a discharge device is required to discharge. If there is
no discharge device, the integration time can be increased.

9.3.3 Adjust the PI parameters of the current loop (under normal circumstances,
do not need to adjust)
Under normal circumstances, increasing the proportional coefficient and the inte-
gral coefficient will speed up the current response speed, but if too large, it will
cause speed shock (specifically, the motor does not rotate, or rotates in random
directions, and emits high-frequency electromagnetic noise at the same time). If
you need to adjust it, first Adjust the proportional coefficient, and adjust the integ-
ral coefficient if the effect is not satisfactory. The PI parameters of the current
loop are related to the motor stator resistance, inductance, carrier frequency of
the system, and current sampling filter time. When the carrier frequency of the
system remains unchanged, the proportional coefficient is proportional to the ind-
uctance, and the integral coefficient is proportional to the resistance. Therefore,
by identifying The output parameter can roughly determine the adjustment dire-
ction of this parameter.

Appendix A: Modbus communication protocol

KD600 series inverter provides RS232/RS485 communication interface and supports Modbus
communication protocol. Users can realize centralized control through computer or PLC, set
inverter running commands, modify or read function code parameters, and read inverter wor-
king status and fault information through this communication protocol.

1.Agreement
The serial communication protocol defines the content and format of information transmitted
in serial communication. It includes: host polling (or broadcast) format; host encoding meth-
od, including: function code required for action, transmission data and error checking, etc.
The response of the slave also adopts the same structure, including: action confirmation,
return data and error checking, etc. If the slave has an error in receiving the information, or
cannot complete the action required by the master, it will organize a fault message as a resp-
onse and feed it back to the master.

2.Application method
The inverter is connected to the "single master and multiple slave" PC/PLC control network
with RS232/RS485 bus.

3.Bus structure
( 1) The interface way RS232/RS485 hardware interface
( 2) Transfer method
Asynchronous serial, half-duplex transmission mode. At the same time, only one of the mast-
er and slave can send data and the other can only receive data. In the process of serial asy-
nchronous communication, data is sent frame by frame in the form of messages.
( 3) Topology
Single master multi-slave system. The setting range of the slave address is 1 to 247, and 0 is
the broadcast communication address. Slave addresses in the network must be unique.

4.Protocol description
Kd600 series inverter communication protocol is an asynchronous serial master-slave Mod-
bus communication protocol. Only one device (host) in the network can establish a protocol
(called "query/command"), other devices (slave) can only provide The data responds to the
"query/command" of the host, or makes corresponding actions according to the "query/com-
Chapter 10

mand" of the host. The host here refers to personal computer (PC), industrial control equip-
ment or programmable logic controller (PLC), etc., and the slave refers to the KD600 inverter.
The master can not only communicate with a certain slave, but also publish broadcast infor-
mation to all the lower slaves. For the "inquiry/command" of the host that is accessed indivi-
dually, the slave must return a message (called a response). For the broadcast information
sent by the host, the slave does not need to respond to the host.

-264-
 Chapter 10 Appendix

5.Communication frame structure

The Modbus protocol communication data format of KD600 series inverter is as follows.
Using RTU mode, message transmission starts with a pause interval of at least 3.5 character
times. This is the easiest to implement with various character times at the network baud rate
(as shown in T1-T2-T3-T4 in the figure below). The first field of the transfer is the device ad-
dress. The transfer characters that can be used are 0...9,A...F in hexadecimal. The network
device continuously detects the network bus, including the pause interval. When the first field
(address field) is received, each device decodes it to determine whether it is destined for its
own. After the last transmitted character, a pause of at least 3.5 character times marks the
end of the message. A new message can start after this pause.
The entire message frame must be transmitted as a continuous stream. If there is a pause of
more than 1.5 character times before the frame is complete, the receiving device will flush
the incomplete message and assume the next byte is the address field of a new message.
Likewise, if a new message follows the previous message in less than 3.5 characters, the
receiving device will consider it a continuation of the previous message. This will cause an
error because the value in the final CRC field cannot be correct.

6.Check method (CRC check method)

CRC (Cyclical Redundancy Check) uses the RTU frame format, and the message includes
an error detection field based on the CRC method. The CRC field detects the content of the
entire message. The CRC field is two bytes containing a 16-bit binary value. It is calculated
by the transmitting device and added to the message. The receiving device recalculates the
Chapter 10

CRC of the received message and compares it with the value in the received CRC field. If the
two CRC values a ​ re not equal, it means that there is an error in the transmission.
The CRC is stored in 0xPFPF first, and then a process is called to process the consecutive 8-
bit bytes in the message with the value in the current register. Only the 8Bit data in each cha-
racter is valid for CRC, and the start and stop bits and parity bits are invalid.

-267-
 Chapter 10 Appendix

In the process of CRC generation, each 8-bit character is XORed with the contents of the
register independently, and the result is moved to the direction of the least significant bit,
and the most significant bit is filled with 0. The LSB is extracted and detected. If the LSB is
1, the register is individually ORed with the preset value. If the LSB is 0, it is not performed.
The whole process is repeated 8 times. After the last bit (8th bit) is completed, the next 8-bit
byte is XORed with the current value of the register independently. The value in the final
register is the CRC value after all bytes in the message are executed.
When the CRC is added to the message, the low byte is added first, then the high byte. The
CRC simple function is as follows:

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

unsigned int crc_value=0xPFPF;

7. Address Definition of Communication Parameters

This part is the content of communication, which is used to control the operation of
the inverter, the status of the inverter and the setting of related parameters.
Read and write function code parameters (some function codes cannot be changed,
and are only used by manufacturers or monitored):
Chapter 10

Function code parameter address marking rules:

The rules are represented by the function code group number and label as the param-
eter address:
High-order byte: P0~PF (group P), A0~AF (group A), B0~BF (group B), C0~CF (group
C),

-268-
 Chapter 10 Appendix

D0~DF (group D), 70~7F (group U) low byte: 00~PF

Such as: P0-11, the address is expressed as F00B;
Notice:
PF group: parameters can neither be read nor changed;
Group U: can only be read, parameters cannot be changed.
Some parameters cannot be changed when the inverter is running; some parameters
cannot be changed no matter what state the inverter is in; when changing the functio-
n code parameters, pay attention to the range, unit, and related descriptions of the
parameters.

Communication Function code address of

P0～PE 0xF000～0xPEPF 0x0000～0x0EPF

C0～CF 0xC000～0xCPFF 0x6000～0x6PFF
U0、U1 0x70xx、0x71xx

Note that, because the EEPROM is frequently stored, the service life of the EEPROM
will be reduced. Therefore, some function codes do not need to be stored in the com-
munication mode, just change the value in the RAM.
If it is a parameter of group P, to realize this function, it can be realized only by chang-
ing the high-order F of the function code address to 0.
If it is a group A parameter, to realize this function, just change the high-order A of
the function code address to 4 to realize it.
The corresponding function code addresses are expressed as follows: high byte:
00~0F (group P), 40~4F (group A) low byte: 00~PF
For example, the function code P0-11 is not stored in the EEPROM, and the address is
expressed as 000B; this address indicates that it can only be written to RAM, but cann-
ot be read. When reading, it is an invalid address.

Note:
Œ
Please select the power and the resistance value recommended by our
company.

The power and the resistance value that recommended above can be
calculated by 100% braking torque and 10% frequency of utilization.
The power and the resistance value can be appropriately reduced as
long as it meets the load demand and the system is reliable: The power
and the resistance value of the braking resistor should be appropriately
changed if the braking torque and frequency of utilization need to be
increased,or users can contact the company.
Ž
When installing a braking resistor， please consider the safety and the
inflammability of the surrounding environment.

The frequency of use of Braking:

UD= t1/ t2*100%

Chapter 10

tl：the braking time in a working period;

t2：a working period;
If the braking efficiency is double, the power of the corresponding braking unit
and braking resistor also need to be double.

-275-
 Chapter 10 Appendix


The resistance of the resistor that over 2500W and the power are the
total amount of resistance and power. The power of the resistor is get
from parallel connection based on 2500W. For example, to get a
25000W 6Ω IS, ten 2500W 60Ω resistors are needed to be connected in
parallel.
The calculation of braking resistor: When the braking current IB flowing
through the energy consumption circuit is equal to half of the rated current
of the motor, the braking torque of the motor is approximately equal to its
rated torque:

IB=IMN/ 2 TB≈TMN or IB=2UB/ IMN

Notes：
IB—braking current，A； IMN—the motor rated current，A；
Tb—braking torque，N▪ m； TMN—rated load torque of motor，N▪m。
As a general rule, the range of choice of braking torque is：
TMN＜TB＜2TMN IMN＜IB＜21MN
According to specific situation，users can decide the braking current according
to the formula(3-12) and (3-13).
After that，it is easy to calculate the braking resistance：
RB= UB/ IB RBmin= UB/ IMN
Notes：
UB is the braking threshold voltage；RB is braking resistor value .
UB is 1. 1times as that of the rated voltage of bus. RBmin is the minimum
braking resistance the common braking threshold voltage：
AC220V: DC380V AC380V: DC680V AC660V: DC1140V
When get IB and RB, the power of resistance will be known.
λ：Actual resistance value/calculated value ED%: Braking efficiency
Suppose that there is a 7. 5KW motor，rated current is 18A and rated input
voltage is 380V and：
Chapter 10

RB=680V/ 9A=75Ω RBmin=680/18=38Ω

Empirically, the value is 75Ω
The power of braking resistor=1*6802/75*0.1=616W The power can be approp-
riately enlarged in actual use.

The detailed Solution steps for setting inverter used on Elevator

Step 1:
P0-28 set to “T to confirm, restore the factory value.
Step 2:
P0-01 is Tto confirm, and then press PRG to exit, and then close the UP Down
terminals. See whether the inverter has forward and reverse running.
Step 3:
Set: P0-06 into 6, multi-step speed is valid.
Step 4:
set F09.30 into 1 and respectively set F06.02 to 4 , F06.03 to 8 and F06.04 to 7.
Close the low-speed switch (the default is S3) and you can see that the frequen-
cy converter runs at 6Hz forward rotation.
Close the high-speed switch (default is S4 terminal) and you can see that the
inverter displays E008 fault.
Close the maintenance speed switch (default is S5 terminal) and you can see
that the inverter E008 fault disappears.
Step 5:
Set F06.02 (S3) to "12” Corresponding to low speed switch Default 10Hz.
F06.03 (S4) is "13” Corresponding to high speed switching 40/50Hz.
F06.04 (S5) is "14” Corresponding maintenance speed switch Speed is set by
parameter F12.06.
Step 6: Set the Speed
F12.03=20 (corresponding to low speed of 10HZ).
F12.04=80 or 100 (corresponding to high speed of 40/50HZ).
F12.06=? We don't know the exact speed you need for this one (corresponding
Chapter 10

to maintenance speed).
Step 7:
set the acceleration and deceleration should be F05.05=0 P0-12/F0-13/
F09.00 / F09.01 /F09.02 /F09.03 / F09.04/F09.05 all set 2.5.

3. Installation and Commissioning Instructions for Photovoltaic Water Pumps

3.1 Wiring:
1st type:
the positive pole of the solar photovoltaic panel output is connected to the inve-
rter "+" terminal, and the negative pole of the solar photovoltaic panel output is
connected to the inverter "-" terminal.
Chapter 10

2nd type:
solar photovoltaic The positive and negative poles of the board output are resp-
ectively connected to the "R" and "T" terminals of the inverter. This method does
not distinguish between positive and negative. The water pump is connected to
the “U” “V” “W” terminals of the inverter.

 Chapter 10 Appendix

3.2 Set the working mode of the photovoltaic water pump:

There are two working modes for the photovoltaic water pump.
The first one is CVT mode. In this working mode, only two parameters need to be set (F16.00
is set to 1, which is used to select CVT working mode; F16) .01 Set the worki-ng voltage point
of CVT mode. Generally, the inverter with voltage level of 380VAC can set this parameter
between 450 and 540, and the inverter with voltage level of 220VAC can set this parameter
between 250 and 310). In CVT mode, when the light intensity state, that is, the inverter bus
voltage exceeds the voltage value set by F16.01, the inverter will speed up the pump running
speed, otherwise the inverter will reduce the pump running speed.
The second working mode is MPPT working mode. In this working mode, the following
parameters need to be set: F16.00 is set to 2, and the working mode is selected as MPPT
working mode. F16.05 and F16.06 respectively set the upper and lower limits of MPPT mode
voltage search (the two parameters generally use the factory values). When running in MPPT
mode, the inverter will automatically search for the maximum power output point according to
the sunlight intensity to ensure the maximum output power. (Because the sunlight intensity
changes in real time, the process of searching for the maximum power point in this mode is a
relatively slow process. And the maxi-mum output power is not equivalent to the maximum
pump operating frequency.) ** CVT working mode is relatively simple and easy to understand
. It is recommended that customers use the CVT mode for testing.

3.3 Start the inverter：

The startup mode of the inverter is determined by the parameter P0-01, and the default is to
start the inverter with the panel keys (ie, manually press the RUN key on the inverter panel to
start the inverter). When the site is in the situation that no one needs to run automatically for a
long time, it is recommended that the customer set P0-01 to 1, and use a wire to connect the
S1 terminal and the DCM terminal together. This setting mode will run automatically as soon
as the inverter is powered on.

3.4 Check the running direction of the water pump：

run with the pump. The running direction of the pump is related to the wiring sequence of the
three motor wires "U", "V" and "W", so after starting the inverter, you need to check the pump
manually Whether the running direction is correct, if the running direction is wrong, you need
Chapter 10

to choose two of the three motor wires "U", "V" and "W" to change the wire sequence.

3.5 Introduction to related faults of photovoltaic water pump:

Sleep display U-L1 When the inverter panel displays this code, it means that the inverter
Œ
enters sleep mode (not a fault). It will enter sleep mode only when the inverter is running
at low speed for a long time. When the sun is strong enough, The inverter will
automatically exit the sleep state and restart. For details, please refer to the detailed
introduction of parameters F08.50 and F08.52.
FULL is displayed when the water is full. When the inverter panel displays this code, it

means that the inverter has detected a water full signal (need to connect a pressure
sensor and other equipment). Refer to parameters F16.08, F16.09, F16.10 for specific
introduction.
Underload display E-PT. When the inverter panel displays this code, it means that the
Ž
inverter has detected an underload. The underload detection is determined by parameters
F16.12 and F16.13. The underload automatic reset time is determined by F16.14. When
the inverter output current is less than the current value set by F16.12 and continues to
run for a period of time (running time is greater than the time set by F16.13), the inverter
will display the underload interface. **If the inverter falsely reports underload, you can set
the underload current (F16.12) parameter to a smaller value. Generally, the no-load
current of a three-phase asynchronous motor is about 30% of the rated motor current.
