Ⅱ. Safety Precautions
1. Before the Power-up
! Caution
!

Check to be sure that the voltage of the main circuit AC power supply matches the input
voltage of the inverter.

The symbol,

, represents ground terminals. Be sure to make correct ground connection

of the earth terminals of the motor and the inverter for safety.
!

No contactor should be installed between the power supply and the inverter to be used for
starting or stopping of the inverter. Otherwise it will affect the service life of the inverter.
Danger

R.S.T terminals are power input terminals, never mixed with U.V.W terminals. Be sure that the
wiring of the main circuit is correct. Otherwise it will cause damages of the inverter when the
power is applied to it.

Caution
!
Do not carry the front cover of the inverter directly when handling. It should be handled with
the base to prevent the fall-off of the front cover and avoid the dropping of the inverter, which
may possibly cause the injuries to people and the damages to the inverter.

Mount the inverter on a metal or other noncombustible material to avoid the risk of fire.

Install the inverter in a safe location, avoiding high temperature, direct sunlight, humid air or
water.

Keep the inverter from the reach of children or persons not concerned.

The inverter can only be used at the places accredited by our company. Any unauthorized
working environment may have the risks of fire, gas explosion, electric shock and other
incidents.

Install a heat sink or other cooling device when installing more than one inverter in the same
enclosure so that the temperature inside the enclosure be kept below 40℃ to avoid overheat or
the risk of fire.

Be sure to turn off the power supply before dissembling or assembling the operation keypanel
and fixing the front cover to avoid bad contact causing faults or non-display of the operator.

Do not install the inverter in a space with explosive gas to avoid the risk of explosion.

If the inverter is used at or above 1000m above seal level, the cooling efficiency will be worse,
so please run it by de-rating.

Do not install any contactor and other components of capacitor or varistor on the output side of
the inverter. Otherwise it will cause malfunctions and damages of components of the inverter.

Do not install any switch component like air circuit breaker or contactor at the output of the
inverter. If any of such components must be installed because of the requirements of process
and others, it must be ensured that the inverter has no output when the switch acts. In addition,
it is forbidden to install any capacitor for improvement of power factor or any varistor against
thunder at the output. Otherwise it will cause malfunctions, tripping protection and damages of

components of the inverter. Please remove them as shown in the below diagram.
!

It will affect the service life of the inverter if a contact is connected to the front end of input of
the inverter to control its starts and stops. Generally it is required to control it through FOR or
REV terminals. Special attention should be paid to its use in the case of frequent starts and
stops.

Please use an independent power supply for the inverter. Do avoid using the common power
supply with an electrical welder and other equipment with strong disturbance. Otherwise it will
cause the protection or even damage of the inverter.

the main control board due to plugging, which might cause the damage of the inverter.

Always have the protective cover in place before the power up to avoid electrical
shock injury.

3. During the Operation
Danger
!

Never connect or disconnect the motor set while the inverter is in running. Otherwise it

will cause over-current trip and even burn up the main circuit of the inverter.
!

Never remove the front cover of the inverter while the inverter is powered up to avoid

any injury of electric shock.
!

Do not come close to the machine when the fault restart function is used to avoid

anything unexpected. The motor may automatically restart after its stop.
!

The function of STOP Switch is only valid after setting, which is different with the use

of emergent stop switch. Please pay attention to it when using it.

! Caution
! Do not touch the heat sink, braking resistor, or other heat elements to avoid being scald.
!

Be sure that the motor and machine is within the applicable speed ranges before

starting operation because the inverter is quite easy to run from lower speed to higher speed.
! Do not check the signals on circuit boards while the inverter is running to avoid danger.
! Be careful when changing the inverter settings. The inverter has been adjusted and set
before ex-work. Do not adjust it wantonly. Please make proper adjustments according to the
required functions.
!

Do consider the vibration, noise and the speed limit of the motor bearings and the

mechanical devices when the inverter is running at or above the frequency of 50Hz.

3. Basic Connection Diagram（
（图表请自行修改）
）
The wiring of the inverter is divided into two parts, main circuit terminal connections and control
circuit terminal connections. The user can see the main circuit terminals, and the control circuit
terminals after removing the cover of enclosure. The terminals must be connected correctly as the
following wiring circuit diagrams.

4. Precautions on Wiring
1)

For the main circuit wiring:

While wiring the sizes and specifications of wires should be selected and the wiring should
be executed according to the electrical engineering regulations to ensure the safety.

It is better to use shielded wire or wire and conduit for power cord and ground the shielded
layer or two ends of wire conduit.

Be sure to install a Non Fuse Breaker (NFB) between the power supply and the input
terminals (R.S.T). (If using ground fault circuit interrupter, please choose one corresponding
to high frequency)

Never connect AC power to the output terminal (U.V.W) of the inverter.

Output wires mustn’t be in touch of the metal part of the inverter enclosure, or it will result in
earth short-circuit.

Phase-shifting capacitors, LC, RC noise filters, etc, can never be connected to the output
terminals of the inverter.

The main circuit wire must be enough far away from other control equipments.

When the wiring between the inverter and the motor exceeds 15 meters for 220V class or 30
meters for 380V class, much higher dV/dT will be produced inside the coil of the motor,
which will cause the destruction to the interlay or insulation of the motor. Please use a
dedicated AC motor for the inverter or add a reactor at the inverter.

Please lower the carrier frequency when there is a longer distance between the inverter and
the motor. Because the higher the carrier frequency is the bigger the leakage current of
high-order harmonics in the cables will be. The leakage current will have unfavorable effect
on the inverter and other equipment.

2） For control circuit wiring (signal line)
!

The signal line should be separately laid in a different conduit with the main circuit wire to
avoid any possible interference.

Please use the shielded cable with the size of 0.5-2mm2 for signal lines.

Use the control terminals on the control panel correctly according to your needs.

3） Grounding
!

Grounding terminal E. Be sure to make correct grounding
220V class: The third grounding method (Grounding resistance should be 100Ω or lower.)
380V class: The special third grounding method (Grounding resistance should be 10Ω or
lower.)

Choose grounding wires according to the basic length and size of the technical requirements
of the electric equipment.

Do avoid sharing grounding wire with other large power equipment such as electric welder,

power machine, etc. The grounding wire should be kept away from the power supply wires
for large power equipment.
!

The grounding method for several inverters together should be done as the first and second
diagrams below. Avoid the third loop.

The grounding wire must be as shorter as possible.

PD003 Main Frequency
Set Range：0.00—400.00 Hz

**
Unit：0.01 Hz

Factory Setting：0.00

In the digital operator mode, the inverter will run at the set value of PD003. During running, the
operating frequency can be changed by pressing ▲ or ▼. During multi-speed running, the main
frequency is taken as the frequency of Speed 1.

In the external control multi-speed mode, if PD002 is set to 1, i.e. given by an external terminal,
Speed 1 will be given by the analog of the external terminal.
The setting of main frequency is limited by the maximum operating frequency.
The related parameters of PD002, PD080 are adjustable during operation.
PD004 Base Frequency
Set Range：0.01—400.00 Hz Unit：0.1Hz

Factory Setting：50.00

This parameter must be set according to the rated frequency of operating voltage on the motor’s
nameplate. Under normal conditions do not change the set value of base frequency at will. If it is
equipped with a special motor this value should be set properly according to the characteristics of
the motor’s parameters. Otherwise it may cause the damage to the equipment.

PD005 Max. Operating Frequency
Set Range：10.00—400.00 Hz

Unit：0.01 Hz

Factory Setting：50.00

This parameter is set for the maximum operating frequency of the inverter.

PD006 Intermediate Frequency
Set Range：0.01—400.00 Hz

Unit：0.01 Hz

Factory Setting：2.50

Note: ** means this parameter is adjustable during operation.
This parameter is set for intermediate frequency of arbitrary V/F curve. If it is set improperly, it
will cause over-current or under-torque of the motor, or even tripping of the inverter.

This set value of intermediate frequency is limited by the set value of base frequency.

PD007 Min. Frequency
Set Range：0.1—20.00 Hz

Unit：0.01 Hz

Factory Setting：0.50

This parameter is set for the min. starting frequency of V/F curve.
The following table has specific factory settings of V/F curve, accel./decal., time and carrier for
the inverter of A series:

PD008 Max. Voltage
Set Range：0.1—*

Unit：0.1V

Factory Setting：220/380V

This parameter should be set according to the rated value of the motor’s nameplate. The factory
setting is 380V for 380V class motor and 220V for 220V class motor. The setting range of this
parameter is restricted by the voltage rating of the inverter. In case of the motor relatively far away
from the inverter this set value can be increased properly.
PD009 Intermediate voltage
Set Range：0.1—500.0V
Unit：0.1V
Factory Setting：15/27.5
This parameter is set for an intermediate voltage value of arbitrary V/F curve. If it is set
improperly, it will cause over-current or under-torque of the motor, or even tripping of the inverter.
When the intermediate frequency is increased the voltage will increase the output torque and at the
same time also the output current. When changing this parameter please pay attention to
monitoring the output current to avoid the inverter’s tripping due to over-current.
The factory setting of intermediate voltage for 220V class inverter is 15, while the factory setting
of intermediate voltage of 380V class inverter is 27.5.
This set value of intermediate voltage is limited by the set value of max voltage. When the
voltage is increasing to a certain value at intermediate frequency the torque compensation will lose
its function. When adjusting this parameter the output current of the inverter should be increased
from low to high slowly according to the load of machines until it meets the starting requirement.
Do not be quick to increase it by large amplitude. Otherwise it might cause the tripping of the
inverter or the damage of the machines.
PD010 Min. Voltage
Set Range：0.1—50.0V

Unit：0.1V

Factory Setting：*

This parameter is set for the min. starting voltage of V/F curve.
The factory setting of min. voltage for 220V class inverters is 8, and the factory setting of
min.voltage for 380V class inverters is 13.5.
This set value is limited by the voltage at the max. frequency.

Note:
The versions previous to Vr2.0 took 50Hz as the base of ramp time.
HY-A Series inverter have altogether 4 Ramp Times. For Ramp Time 2.3.4 the user can select the
different ramp up or down time through the external terminals or switching of ramp time
according to the actual needs. In the internal control multi-speed operation, different ramp time
can be selected through easy PLC.
Generally the default of the inverter is Ramp Time 1, which is factory set depending on the model.
Ramp Time 4 is for the jogging ramp time. For the factory setting of parameters refer to the table

PD023 Rev Rotation Select

Set Range：0—1

Unit：1

Factory Setting：1

0: Rev Rotation disable
1: Rev Rotation Enable
This function is suitable for the motor, which is not allowed to rotate reversely, to prevent workers
from false operation. When the reverse rotation is disabled, the motor can only rotate forward, not
reverse.

PD024 STOP key
Set Range：0—1

Unit：1

Factory Setting：1

0：STOP invalid.
1：STOP valid.
This parameter set is only valid when PD001 is set to l or 2.
When the control mode is set for external terminals or communication control, STOP key on the
panel can be chosen to be valid or invalid. When choosing it as valid, STOP key can stop the
inverter in running. When it needs to restart, the former running signal must be released before
restarting the inverter.
PD025 Starting Mode
Set Range：0—1
Unit：1
Factory Setting：0
Two starting modes are available for the needs of different equipment.
0：Start from the starting frequency.
When PD029 is set to 0, i.e. DC braking is invalid at start, it starts running from the starting
frequency. When PD029 is set to any non-zero value, i.e. DC braking is valid at start, itl first
performs a DC braking at start, and then starts from the starting frequency.
For the related parameters refer to PD035, PD031 and PD029.
1：Start by frequency track
This setting can be used for the restarting of large inertia load. When restarting, the inverter will
trace the former frequency from the set frequency downward. In case of large inertia equipment,
when restarting, it can implement the running command and track the former frequency right
away without waiting for the complete stop of the equipment to save time.
Note: When the inverter is restarted by frequency track, it will start tracking the frequency from
its set frequency downward, and search it at the highest speed. When restarting, the current
becomes higher, and over-current or stall may occur. So attention must be paid to the adjustment
of current level of frequency track. Generally, PD033 is adjusted around 100. The concrete value
can be set according to the characteristics of mechanical load.

PD026 Stopping Mode
Set Range：0—1

Unit：1

Factory Setting：0

Two stopping modes are available for the needs of different equipment.
0：Decelerating Stop
When PD030 is set to 0, DC braking is invalid. When DC braking is invalid, the inverter will
decelerate to the stopping frequency, and then stop outputs, and the motor will coast to stop. When
PD030 is set to any non-zero value, DC braking is valid, and the inverter will first decelerate to
the stopping frequency, and then stop by DC braking.
DC braking at stop is usually used for high position stop or for positioning control. It must be
noticed that frequent uses of DC braking will cause over-heat of the motor.
For the related parameters refer to PD028, PD031 and PD030.
1：Coasting Stop
When the inverter receives a STOP command, it will immediately stop output and the motor will
coast to stop. When the coasting stop mode is selected, DC braking is invalid.
PD027 Starting Frequency
Set Range：0.1—10.0 Hz

Unit：0.1Hz

Factory Setting：0.5

Starting frequency is the initial frequency when the inverter is started. If the starting frequency is
set to 4.0Hz, the inverter will run between 4.0 Hz and the maximum operating frequency after its
start at 4.0Hz . The actual maximum operating frequency is limited by the upper limit of
frequency.
For the related parameters refer to PD025, PD031 and PD029.
PD028 Stopping Frequency
Set Range：0.1—10.0 Hz

Unit：0.1Hz

Factory Setting：0.5

When stopping the inverter will decrease its frequency to the stopping frequency and then stop
running or start DC braking to stop.
If PD030 is set to 0, DC braking is invalid at stop and the inverter will stop running.
If PD030 is set for valid, the inverter will stop by DC braking.
For the related parameters refer to PD026, PD031 and PD030.
PD029

DC Braking Time at Start
Set Range：0.0—25.0S

Unit：0.1S
Factory Setting：0.0
This parameter is set for DC Braking at start and the
lasting time of DC Braking current to the motor. If it
is set to zero it means DC braking is invalid.
DC braking at start is normally used in the

Pd027

application, in which the load is movable when the
T
Pd029

machine is at stop, such as windmill. Because of the
load existing before the inverter drives, the motor is
often in coasting with an uncertain rotation direction.

So the DC braking can be executed before starting the motor to prevent the inverter from tripping.

This setting is valid only when PD025 is set to 0. For the related parameters refer to PD025,
PD031 and PD027.
PD030

DC Braking Time at stop
Set Range：0.0—25.0
Unit：0.1S

Factory Setting：0.0

Note: When this parameter is set to any non-zero
value it starts DC brake at stop and sends the DC
braking time to the motor. DC braking at stop is
often used for a high-level stop or positioning

Pd028
T
Pd030

control. When this parameter is set to zero it closes
DC braking at stop.
This setting is valid when PD026 is set to 0. For
the related parameters refer to PD026, PD028 and

PD031.
PD031

DC Braking Voltage Level
Set Range：0.0—20.0%

Unit：0.1%

Factory Setting：2.0

This parameter is set for the DC braking voltage to the motor at start and stop. It can be adjusted
for different braking voltage. When adjusting the parameter it must be increased slowly from
lower value to high value until the sufficient braking torque is achieved.
The voltage at maximum frequency is 100% voltage.
PD032

Frequency Track Time
Set Range：0.1—20.0S

Unit：0.1S

Factory Setting：2.0

This parameter is set as frequency track time when the inverter is started by frequency track after
an external abnormality or temporary power breakdown. For starting or stopping of some large
inertia load, if restarting a machine after its complete stop, it will waste much time because of its
large inertia of load. But if the frequency track is started, it is not necessary to wait for the
machine to come to a full stop for restart. The inverter will trace the frequency from high to low
with the set frequency. After searching it will continue to accelerate to reach the set frequency.
PD033

Current Level for Frequency Track
Set Range：0—200%

Unit：1%

Factory Setting：150

When the inverter is tracing the frequency this set value is taken as the level for output current.
When the output current is higher than this level the inverter will decrease the frequency to restore
the current below the level and then it will execute the frequency track again.
PD035 Up/down

Frequency Step Length: 0.01~2.5

Factory Setting：

0.01
This parameter can be set in combination with PD078 for Up/Down of external control and the
speed of increase and decrease.
In case of PD078=1 the step length of Up/Down=the set value of PD035, i.e., the range can be set
to 0.01~25HZ.
In case of PD078=0 the step length of Up/Down=the set value of PD035 ×10, i.e., the range can

be set to 0.1~25.0HZ.
（Note: 0—15 corresponds to 0—20K Hz）

PD041 Carrier Frequency
Set Range：0—15

Unit：1

Factory Setting：5

The carrier frequency has some relation with the electromagnetic noise of the motor, and
meanwhile the level of the carrier frequency has certain relation with the heating capacity of the
inverter and the interference to the environment. See the following table：

As shown in the table above, the higher the carrier is, the lower the electromagnetic noise of the
motor will be, but the stronger its interference to other systems will be and the greater the heating
capacity of the inverter will have. Under higher ambient temperature and heavier load of the motor
the carrier frequency should be decreased properly to improve the heat characteristics of the
inverter.
The factory setting of carrier frequency is depending on the model. For specific data refer to the
table in the description of PD007.
PD042 Jogging Frequency
Set Range：0.00—400.00

**
Unit：0.01

Factory Setting：5.00

The parameter set can realize the jogging function when the inverter is tested. The jogging
operation can be only achieved through the external terminals, which can be set by multi-input
terminals. Jogging frequency is limited by the frequency upper/lower limits. While the jogging
function is implemented, other running commands are invalid. The ramp-up time of jogging
frequency is set by Ramp-up Time 4. When the jog button is released the inverter will stop output
immediately. In case of jogging function please set the corresponding multi-input terminals to 07
or 08.
This function is only valid at stop. It is invalid at running. For the related parameters refer to
PD044-PD049.

PD043 S-Curve Time
Set Range：0—6500S

Unit：1

Factory Setting：1

This parameter can be set for no impact slow start or slow stop of the inverter when starting or

stopping. When starting S-curve the inverter will make accelerating or decelerating curve of
different speed rates according to Ramp Time.
When PD043 is set as 0, S-curve is invalid, i.e. it will accelerate or decelerate in linear. Without
consideration of stall the actual accel/decal time = (PD008+PD043)/2. The parameter is only valid
when PD008 is less than PD043.

⑻ Example 2:
The following is that get CRC value with C language. The function has two parameters:

Unsigned char data
the point of data buffer
Unsigned char length
number of data buffer
This function will send back the CRC value with unsigned integer format.
Unsigned int crc_chk (unsigned char data, unsigned char length)
{
int j;
unsigned int reg_crc=0xffff;
while (length--){
reg_crc^=*data=++;
for(j=0;j<8;j++={
if(reg_crc&0×01){/*LSB(b0)=1*/
reg_crc=(reg_crc>>1)^0xa001;
}else{
reg_crc=reg_crc>>1;
}
}
}
return reg_crc;
}
