use, re-use after leaving unused for a long time as well as
regular check, in order to prevent damage to the inverter
because of the motor's winding insulation failure. Wiring
between motor and inverter shall be disconnected, it is
recommended that the 500V voltage type megger should be
adopted and insulation resistance shall be not less than
5MΩ.
2
Motor thermal
protection
If the rated capacity of the selected motor does not match
the inverter, especially when the inverter rated power is
greater than the motor rated power,be sure to adjust the
motor protection parameter values inside inverter or install
thermal relay in the front of motor for motor protection.
3
Run over power
frequency
This inverter can provide (0Hz to 400Hz ） output
frequency If the user is required to run at 50Hz or more,
please consider the endurance of your mechanical devices.

resonance point of the load device, you can set jump
frequency parameter inside inverter to avoid the case.
Chapter 1 Inspection and Safety Precautions
5
No.
Type
Explanation
5
Motor heat and
noise
The inverter output voltage is PWM wave that contains a
certain amount of harmonics, so the temperature rise,noise
and vibration of motor show a slight higher than frequency
power frequency operation.
6
Output side with
piezoresistor or
capacitor for
improving power
factor
The inverter output is PWM wave, if the piezoresistor for
lightning protection or the capacitor for improving power
factor is installed in the output side, which easily cause the
inverter instantaneous overcurrent or even cause damage to
the inverter. Please do not use.
7
Contactor or
switch used in the
inverter
input/output
terminals
If contactor is installed between power supply and
inverter,the contactor is not allowed to start/stop the
inverter. Necessarily need to use the contactor to control the
inverter start/stop, the interval should not be less than one
hour. Frequent charging and discharging may reduce the
service life of the inverter capacitor. If the contactor or
switch is equipped between output terminals and motor, the
inverter should be turned on/off without output status,
otherwise which easily lead to damage to the inverter
module.

Type
Explanation
2) The cooling fan and the rotor shaft for non-inverter motor
are coaxially connected, the fan cooling effect is reduced
when the rotational speed is reduced, therefore, when the
motor works in overheating occasions,a strong exhaust
fan should be retrofitted or replace non-inverter motor
with the inverter motor;
3) The inverter has built-in the adaptive motor standard
parameters, according to the actual situation, please
identify motor parameters or accordingly modify the
default values to try to meet the actual value,otherwise it
will operation affect and protection performance;
4) When short-circuit of cable or motor internal will activate
the inverter alarm, even bombing. Therefore, firstly
perform insulation short-circuit test for the initial
installation of the motor and cable, routine maintenance
often also need to perform such test. Note that the parts to
be tested and the inverter shall be disconnected
completely when testing.

In the third-level menu status, if the parameter has not blinking bit, it means that the
function code can not be modified, the possible causes include:
1) The function code can not be used to modify the parameters. Such as actual detection
parameters, run record parameters.
2) The function code can not be modified in the running status,can be modified only
after this unit is stopped.
How to view status parameters
In stop or run status, operate SHIFT key to display a variety of status parameters
respectively. Parameter display selection depends on function code F6.01 (run
parameter) and F6.02 (stop parameter) .
In stop status, there are 10 run status, you can set to display or not display them: set
frequency, bus voltage, DI input status, DO output status, PID settings and PID
feedback, analog input AI1 voltage, analog input AI2 voltage,and switch and display the
selected parameter by pressing key orderly.
In run status, there are 16 run status, you can set to display or not display them:
running frequency, set frequency, bus voltage, output voltage, output current, output
power, output torque, DI input status, DO output status, analog input AI1 voltage,
analog input AI2 voltage, linear speed, PID settings and PID feedback,etc, their display
depends on function code F6.01, and switch and display the selected parameter by
pressing key orderly.
Inverter powers off and then powers on again, the displayed parameters are the
selected parameters before power-off.
3-4-1.Password Settings
The inverter has password protection, when Y0.01 is non-zero value, that is user
password, password protection will enter into force when you exit from function code
editing status, press the PRG key again,it will display "-----", you must enter correct
user password before entering regular menus, otherwise inaccessible.
To cancel the password protection function, firstly enter correct password to access
and then set Y0.01 to 0.
3-4-2.Motor parameter auto tunning
Select the operating mode of vector control, you must accurately input parameters
of the motor's nameplate before inverter operation, PI130 frequency inverter will match
the standard motor parameters according to the nameplate parameters; the vector control
method is highly dependent on motor parameters, in order to get good control
performance, the accurate parameters of the controlled motor must be required
Motor parameter auto tunning steps are as follows (Take asynchronous motor as an
example) :
Firstly select command source as keyboard control (F0.04=0）. then input the
following parameters according to the actual motor parameters (selection is based on the
current motor) :

If the motor can completely disengage its load, please select 1 (asynchronous
motor parameter comprehensive auto tunning) for b0.11, and then press the RUN key on
the keyboard panel:
If the motor can NOT completely disengage its load, please select 2 (asynchronous
motor parameter static auto tunning) for b0.11, and then press the RUN key on the
keyboard panel, the inverter will automatically calculate the motor‟s following
parameters:

Chapter 5 Function parameter
5-1.Menu grouping
PI130 inverter function parameters are grouped by function, there is d0 group, F0
group to Fb group, E0 group to E3 group, b0 group, y0 group to y1 group, L0 group, a
total of 21 groups. Each functional group includes several functional code.
F group and E group are the basic function parameters, d group is monitoring
function parameters and b group is motor parameters.
In order to more effectively carry out parameter protection, the inverter provides a
password protection of function code. y0.00 is used to set parameters protection
password, you can enter into parameter menu only after inputing correct password
under function parameters mode. Password protection is canceled when y0.00 is set to
00000.
L0 group is factory function parameters, users do not have access to the group of
parameters.
Function parameter table "Change", change properties (ie, whether to allow the
change or not and change conditions) and symbol description is as follows:
"★": indicates that the parameter value can not be changed when the inverter is
running;
"●": indicates that the parameter value is the actual measured value, can not be
changed;
"☆": indicates that the parameter value can be changed when the inverter is
running or stoped;
“▲”: "Factory parameters", prohibit the user to operate;
"-": indicates that the parameter factory default is none or the value is undefined.

The advantage of high carrier frequency: there are more ideal current waveform, less
current harmonics and less motor noise.
The disadvantage of high carrier frequency: switching loss increases, the inverter
temperature increases, the inverter output is affected, the inverter derates under high
carrier frequency; the leakage current of the inverter increases, the electromagnetic
interference on external increases.
The low carrier frequency has contrary the case described above, the too low carrier
frequency will cause the instability of low frequency operation, the torque reduction

Increasing the proportional gain as well as decreasing integral time, which can
accelerate the speed loop dynamic response, but the too large proportional gain is or the
too small integration time easily cause system oscillation and too large overshoot. The
too small proportional gain also easily lead to the system steady-state oscillation, and

Only when F0.00 = 3, both torque control and FA.00 function code are valid.
Under torque control mode, the inverter outputs torque according to the set output
torque command, the output frequency is limited by upper limit frequency, when the
load speed is greater than the set upper limit frequency, the inverter output frequency
will be limited, at the time the output torque is different from the set torque.
When the torque command is set by the keyboard (FA.00 = 0), the torque command
can be obtained from setting the function code FA.01. When the torque is set to
negative, the motor will reverse. Analog, multi-speed and communication settings, the
set 100.0% corresponds to two times of rated inverter current and the set -100.0%
corresponds to negative 2 times of rated inverter current.
The multi-function input terminals are used to switch between torque control and speed
control.
When the set torque of inverter is greater than the load torque, the inverter output
frequency will rise, when the inverter output frequency reaches the upper limit of the
frequency, the inverter will run at the upper limit frequency.
When the set torque of inverter is less than the load torque, the inverter output
frequency will fall, when the inverter output frequency reaches the lower limit of the
frequency, the inverter will run at the lower limit frequency.
Note: In the state of stop, the inverter automatically switches from torque control to

Proportional gain (KP) : used to decide the extent of the PID regulator,the greater P,the
greater adjusting extent. This parameter 100 means that when the deviation of PID feedback value
and setting value is 100%, the PID regulator will adjust the output frequency command to the
maximum output frequency (Ignore the integral and differential actions) .
Integration time (Ti) : used to decide the speed that PID regulator adjusts integrally the
deviation between feedbacks and settings of PID. The integration time means that when the
deviation of PID feedback value and setting value is 100%, the integration regulator (Ignore
proportional and derivative actions) will successively adjust to the maximum o utput frequency
(F0.08) for the time. The shorter integration time, the greater extent of integral adjustment
Differential time (Td) : used to decide the extent that PID regulator adjusts the deviation
between feedbacks and settings of PID. The differential time means that the feedback value
changes 100% within the time, the differential regulator will adjust to the maximum output
frequency (F0.08) (Ignore proportional and integral action) . The longer differential time, the
greater extent of adjustment
PID is the most commonly used control method in the process control, and the role of its
each part varies, the working principle and the adjusting method is briefly described as follows:
Proportional adjustment (P) : When the deviation between feedback and setting exists, as for
the adjustment amount that the output is proportional to the deviation, if the deviation is constant,
then the adjustment amount will be constant too. Proportional adjustment can respond quickly to
changes in the feedback, but simply adopt proportional adjustment, which can not realize the
control without difference. The larger proportional gain, the faster the system adjustment, but if
the too large proportional gain will cause oscillation. How to adjust: firstly set integration time to
very long, and set differential time to zero, simply adopt proportional adjustment to make the
system running, then change the setting value to observe the deviation (static difference) between
feedback signal and setting amount, if the static difference changes in the direction of setting
amount (for example, when increasing setting amount, the feedback amount is always less than
setting amount after the system is stable), continue to increase the proportional gain, and vice
versa reduce the proportional gain, repeat the above process until the static difference is relatively
small (it is hard to achieve zero static difference) .
Integration time (I) : when the deviation between feedback and setting exists, the output
adjustment amount continuously increases, if the deviation persists, the adjustment amounts will
continue to increase until zero deviation. The integration regulator can effectively eliminate static
difference. If the action of integration regulator shows too strong, the overshoot occurs repeatedly,
the system shows unstable until oscillation. The oscillations caused by too strong integral action is
characterized by that the feedback signal bobs and the range of oscillation gradually increases
until the oscillation. The integration time parameter adjustment generally descend, gradually
adjust the integration time to observe the effect of system adjustment until the system reaches the
steady speed requirements.
Differential time (D) : when the deviation of feedback and setting changes, as for the
adjustment amount that the output is proportional to the deviation, the adjustment amount only
have something to do with the direction and size of deviation change, not itself direction and size.
The role of differential regulation adjusts according to the changing trends when the feedback
signal changes,thereby suppressing the changes of feedback signal. Please use differential
regulator with caution, because the differential easily amplify the interference of system,
especially the interference of high changes frequency.

It is different from ordinary digital input terminal, the state of virtual VDI has
two kinds of setting, the selection depends on E3.06.
If the state of selection VDI is determined by the state of corresponding virtual
VDO, the availability of VDI depends on the valid or invalid VDO output, and VDIx
only binds VDOx (x is 1 to 5) .
if the state of selection VDI is set by the function code, the status of virtual
input terminals can be determined through E3.05 binary bits respectively.
The following example illustrates the use of VDI. Example 1, to achieve the
following function: "Upon arrival of running frequency, the inverter will perform
free stop" Using the following settings method: set that the VDI state selection
depends on VDO, set VDI1 function as "free stop" (E3.00 = 8) ; set that VDI1
terminal active mode depends on VDO1 (E3.06 = xxx0) ; set VDO1 output function
as "Frequency Arrival" (E3.11 = 5) ;

Note: please set up according to the motor nameplate parameters. The excellent
vector control performance needs the accurate motor parameters.
The inverter provides the function of parameter auto tunning. The accurate
parameter auto tunning depends on correctly inputing parameters on the motor
nameplate.
In order to guarantee the control performance, please try to ensure that the inverter
power matches the motor power, if the gap between the two is too large, the inverter
control performance will be significantly reduced.
Note: Resetting the motor rated power (b0.01) will initialize motor parameters

Chapter 6 EMC (Electromagnetic Compatibility)
6-1.Definition
Electromagnetic compatibility refers to the ability that the electric equipment runs
in an electromagnetic interference environment and implements its function stably
without interferences on the electromagnetic environment.
6-2.EMC Standard
In accordance with the requirements of the Chinese national standard
GB/T12668.3, the inverter must comply with the requirements of electromagnetic
interference and anti- electromagnetic interference.
Our existing products adopt the latest international standards: IEC/EN61800-3:
2004 (Adjustable speed electrical power drive systems part 3:EMC requirements and
specific test methods),which is equivalent to the Chinese national standards
GB/T12668.3. EC/EN61800-3 assesses the inverter in terms of electromagnetic
interference and anti-electronic interference. Electromagnetic interference mainly tests
the radiation interference, conduction interference and harmonics interference on the
inverter (necessary for civil inverter)
Anti-electromagnetic interference mainly tests the conduction immunity, radiation
immunity, surge immunity, EFTB (Electrical Fast Transient Burs) immunity, ESD
immunity and power low frequency end immunity (the specific test items includes: 1.
Immunity tests of input voltage sag, interrupt and change; 2.commutation notch
immunity; 3. harmonic input immunity ; 4. input frequency change; 5. input voltage
unbalance; 6. input voltage fluctuation) . The tests shall be conducted strictly in
accordance with the above requirements of IEC/EN61800-3, and our products are
installed and used according to the guideline of the Section 7.3 and can provide good
electromagnetic compatibility in general industry environment.
6-3.EMC Directive
6-3-1.Harmonic Effect
The higher harmonics of power supply may damage the inverter. Thus, at some
places where the quality of power system is relatively poor, it is recommended to install
Chapter 6 EMC (Electromagnetic Compatibility)
92
AC input reactor.
6-3-2.Electromagnetic Interference and Installation Precautions
There are two kinds of electromagnetic interferences, one is the interference from
electromagnetic noise in the surrounding environment to the inverter, and the other is
the interference from the inverter to the surrounding equipments.
Installation Precautions:
1) The earth wires of the Inverter and other electric products ca shall be well
grounded;
2) The power cables of the inverter power input and output and the cable of weak
current signal (e.g. control line) shall not be arranged in parallel but in vertical if
possible.
3) It is recommended that the output power cables of the inverter shall use shield
cables or steel pipe shielded cables and that the shielding layer shall be grounded
reliably, the lead cables of the equipment suffering interferences shall use twisted-pair
shielded control cables, and the shielding layer shall be grounded reliably.
4) When the length of motor cable is longer than 100 meters, it needs to install
output filter or reactor.
6-3-3.Remedies for the interferences from the surrounding electromagnetic
equipments to the inverter:
Generally the electromagnetic interference on the inverter is generated by plenty of
relays, contactors and electromagnetic brakes installed near the inverter. When the
inverter has error action due to the interferences, the following measures is
recommended:
1) Install surge suppressor on the devices generating interference;
2) Install filter at the input end of the inverter,please refer to Section 6.3.6 for the
specific operations.
3) The lead cables of the control signal cable of the inverter and the detection line
shall use the shielded cable and the shielding layer shall be grounded reliably.
6-3-4.Remedies for the interferences from the inverter to the surrounding
electromagnetic equipments:
These noise interferences are classified into two types: one is the radiation
Chapter 6 EMC (Electromagnetic Compatibility)
93
interference of the inverter, and the other is the conduction interference of the inverter.
These two types of interferences cause that the surrounding electric equipments suffer
from the affect of electromagnetic or electrostatic induction. Further,the surrounding
equipment produces error action. For different interferences, please refer to the
following remedies:
1) Generally the meters, receivers and sensors for measuring and testing have more
weak signals. If they are placed nearby the inverter or together with the inverter in the
same control cabinet, they easily suffer from interference and thus generate error actions.
It is recommended to handle with the following methods: away from the interference
source as far as possible; do not arrange the signal cables with the power cables in
parallel and never bind them together; both the signal cables and power cables shall use
shielded cables and shall be well grounded; install ferrite magnetic ring (with
suppressing frequency of 30 to 1,000MHz) at the output side of the inverter and wind it
2 to 3 turns; install EMC output filter in more severe conditions.
2) When the interfered equipment and the inverter use the same power supply, it
may cause conduction interference. If the above methods cannot remove the
interference, it shall install EMC filter between the inverter and the power supply (refer
to Section 6.3.6 for the selection operation) ;
3) The surrounding equipment shall be separately grounded, which can avoid the
interference caused by the leakage current of the inverter's grounding wire when
common grounding mode is adopted.
6-3-5.Remedies for leakage current
There are two forms of leakage current when using the inverter. One is leakage
current to the earth, and the other is leakage current between the cables.
1) Factors of affecting leakage current to the earth and its solutions:
There are the distributed capacitance between the lead cables and the earth. The
larger the distributed capacitance,the larger the leakage current;the distributed
capacitance can be reduced by effectively reducing the distance
between the inverter and the motor. The higher the carrier frequency,the larger the
leakage current. The leakage current can be reduced by reducing the carrier frequency.
However, the carrier frequency reduced may result in
Chapter 6 EMC (Electromagnetic Compatibility)
94
the increase of motor noise.Please note that additional installation of reactor is also
an effective method to solve leakage current problem.
The leakage current may increase with the increase of circuit current. Therefore,
when the motor power is higher, the corresponding leakage current will be higher too.
2) Factors of producing leakage current between the cables and its solutions:
There is the distributed capacitance between the output cables of the inverter. If the
current passing lines has higher harmonic, it may cause resonance and thus result in
leakage current. If the thermal relay is used, it may generate error action.
The solution is to reduce the carrier frequency or install output reactor. It is
recommended that the thermal relay shall not be installed in the front of the motor when
using the inverter, and that electronic over current protection function of the inverter
shall be used instead.
6-3-6.Precautions on Installing EMC input filter at the input end of power supply
1) Note: when using the inverter, please follow its rated values strictly. Since the
filter belongs to Classification I electric appliances, the metal enclosure of the filter and
the metal ground of the installing cabinet shall be well earthed in a large area, and have
good conduction continuity, otherwise there may be danger of electric shock and the
EMC effect may be greatly affected. Through the EMC test, it is found that the filter
ground end and the PE end of the inverter must be connected to the same public earth
end, otherwise the EMC effect may be greatly affected.
2) The filter shall be installed at a place close to the input end of the power supply
as much as possible.
