1.2 Application Range
CAUTION
This inverter is applicable to general industrial purpose
three-phase AC asynchronic electric motor.
WARNING
1.3 Installation Ambient
CAUTION
Be sure to install the inverter on metallic materials (i.e.,
Metal). Otherwise, there is in the danger of fire.
Be sure not to let the foreign matter enter into the inverter,
such as wire clippings, spatter from welding, metal (zinc or
ferrous) meshavings and etc. Otherwise, there is the danger
of getting burned due to short circuit.
1.4 Cautions for Installing
Be sure to install the inverter in a well-ventilated indoor
location. To get the best cooling effect, it is recommended
to fix the inverter vertically, and extra ventilation devices
are needed when installed horizontally.
Be sure that the ambient temperature is between -10~40 .
If the temperature is higher than 40 , forced heat radiation
or derating is needed from the external. It is recommended
not to use the inverter in such a high temperature. Otherwis e, it
may greatly reduce the service life of the inverter.
The ambient humidity is required to be lower than 90%
without dew condensation.
The inverter shall be installed in a place where the vibration
is less than 0.5G. Otherwise, it may fall and cause damage
to the equipment. It is also noted worthy that the inverter could
not bear any sudden bump.
The inverter should be kept away from electromagneti c
interference (EMI), flammable and explosive ambient.
-2-
HAZARD
WARNING
Do not operate electrical equipment with wet hands.
Do not operate wiring unless the power supply is completely
off.
Do not open the front cover or perform wiring while
the inverter is powered ON. Otherwise, there is the danger
of electric shock.
Do wait at least 5 minutes after the power is disconnected
before performing the work of wiring or inspection. Otherwise,
there is the danger of electric shock.
Do not install or operate if the inverter is damaged or has
parts missing to prevent injury to personnel or loss of
property.
The main loop terminal should be tightly connected to the
cable. Otherwise, the inverter may be damaged due to loose
contact.
The ground term inal must be reliably and properly grounded
to ensure security. To avoid common ground impedance,
multi-piece inverters should be grounded with one shared
point, as shown in the Figure 1-1.

DO NOT connect control terminals (except terminals mar ked
"TA", "TB" and "TC") to AC 220V power supply, which
may cause damage to the inverter.
DO NOT connect AC power supply to the output terminals
marked "U", "V" and "W". Otherwise, it may cause damage
to the inverter, as shown in the Figure 1-2.
It is not suitable to install an electromagnetic contactor in the
side of output power supply, because the operation of open
and close to the contactor when the motor is running may
cause damage to the inverter arising from over-voltage
produced during this process. But it is still necessary to install
a contactor if one of the following three points occurs:
1. The system of frequency converting governor used to control
energy-saving usually works at a rated rotation speed. To run the
governor economically, there is a must to remove the inverter.
2. The inverter participates in some import procedure and cannot
stop operating for a long period of time. To realize free shift
in various control systems and improve the reliability of these
systems, there is a must to install a contactor.
3. When an inverter controls several motors, there is a must to
install a contactor.
Caution: DO NOT operate the contactor if there is output of the
inverter.

HAZARD
Do not operate electrical equipment with wet hands.
An inverter stored for more than half a year should be given
power up test before use so that the main circuit filter capacitor
could be recovered. When the inverter is in the state of powerup,
it is necessary to raise the voltage gradually to the rated value
with a voltage regulator. Generally, the charging time should
be controlled within 2 hours. Otherwise, there is the danger
of electric shock or exposure.
Do not touch the inner side of the inverter while the po wer
is ON, nor put any foreign matter, i.e., rod or other matter
inside the inverter. Otherwise, it may result in serious damage
to the equipment or electric shock.
Do not open the front cover while the inverter is powered
ON. Otherwise, there is the danger of electric shock.
Be careful to select the Restart Mode. Otherwise, there is
the danger of personnel death.

WARNING
When the inverter runs at a frequency higher than 50Hz, Make
sure it is within the speed range acceptable by your motor
bearing and mechanical device. Otherwise, there is the danger
of damage to the motor.
It is not advisory to run the reduction box, gear and other
mechanism that need lubricating at low speed for a long period.
Otherwise, it may reduce the service life of these equipment
or even damage the equipment.
A general motor should be derated before use due to less
effective of heat dissipation when it runs at a low frequency.
If it is a constant torque load, then a forced method or a special
variable frequency motor should be used to release heat.
DO cut off the power supply of an inverter set aside for a long
time to avoid foreign matter or other things enter in it which
may cause damage to the inverter or even lead to fire.
The output voltage of inverter is PWM impulse wave. DO
NOT install a capacitor or surge current sink (i.e., a varistor)
in the inverter output port. Otherwise, there is the danger of
fault tripping of the inverter or damage to its power elements.
DO remove such kind of things if already installed. See the
Figure 1-3 below.

Surge current sink
Motor insulation should be checked before the inverter is
used for the first use or reused after a long-term idle. Be sure
the insulation resistance measured is no lower than 5M?
If the inverter is used beyond the range of allowable working
voltage, then an extra step-up or step-down voltage transformer
shall be configured.
Due to thin air in a place where the altitude is higher than
1,000m , the heat dissipation of inverter will be less effective.
Hence derating should be done before use. In general, when
the height rises by 1,000m, the rated voltage of the inverter
shall reduce by 10%.

When the open-ended output terminal of the collector
connects to any inductive load, i.e., the relay coil, do insert
a diode at each end of the load in parallel.
The control wire in the inverter or the control cabinet should
be at least 100mm away from the power cable. DO NOT put
them in the same metallic channel. If the signal wire and
the power cable need to intersect, they should intersect at
an angle of 90 . The control wire must adopt STP (shielded
twisted pair wire); the shielded layer must connect to the
terminal GND; and the power wire is recommended to use
metallic shielded cable.

Be sure to connect the ground terminal and the motor casing
to the ground wire which must be copper core. The diameter
of the copper core should conform to the relevant national
standard. The ground resistance should be less than 10 .
Tips

The unavoidable strong electromagnetic interference of
the inverter may have bad influence on all the electrical
equipment and meters in the same environment. To reduce
interference, the output cable of the inverter can be inserted
in the metal pipe connecting to the ground or in the metallic
shielded cable, and connect the metallic shielded layer to
the ground. In addition, a magnetic loop put on the output
cable is also effective to reduce interference.

Tips
The circuit breaker has the function of over-current
protection, which can avoid extension of external
equipment failure. Do pay attention to the capacity of
circuit breaker when installing.
The magnetic contactor is used to disconnect fro m the
main power supply in case of inverter failure, and prevent
restarting after power-off or inverter failure.
The input AC reactor can reduce influence arising from
unbalance of three-phase AC power supply, improve the
power factor of the inverter input side and reduce damage
to the inverter when it is connected to large capacity motor
which may result in damage to the rectifier circuit. It is
necessary to configure an AC reactor when any of the
following occurred:
The power supply unbalance exceeds 3%.
The power capacity is 500KVA at least and it is more
than 10 times as the inverter capacity.
The power factor is used to compensate the connection
or disconnectio n of the capacity, and sudden fluctuation
of network voltage caused by other reasons.
It is recommended to install a reactor with derating voltage
of 3%.
The input and output EMI filters are used to minimize
the magnetic or radio frequency interference (RFI)
produced by the network or the inverter.
The brake assembly is used to consume the energy fed
back by some heavy potential energy or inertia load to
the inverter, so as to avoid inverter tripping arising from
over-tension pumping voltage while giving a quick
shutdown to the inverter.
The output AC reactor can filter out with effect the higher
harmonic compon ents in the inverter output current and
reduce the electromagnetic interference (EMI) due to
ultraharmonics. Also, it can improve current waveform,
decrease noise and temperature rise of a running motor
and enhance the stability of motor running. To avoid
influence of leakage current due to distributed capacity
of the cable, it is necessary to install an output AC reactor

The inverter stops outputting, the motor stops running
and the trial operation ends. If everything is normal,
please repeat the operation for several times.
The following steps should be inspected and confirmed before the trial
operation of the inverter:
Be sure the application ambien t and installation for the inverter is
in accordance with the requirements specified in Clause 3.1.
Be sure the main circuit is correctly wired. The input power supply
of the inverter must be connected to the terminal R, S and T(or L,
N. The output terminal U, V and W must be connected to the motor.
Be sure the ground terminal is reliably and properly grounded.
Be sure all the switches and terminals are in proper state of off or
shut down.
Be sure there is no short cutting or short to ground of all the terminals
and electrified parts.
Be sure all the terminals, connectors and screws are tightly fastened .
Be sure the motor has no other loads.
5.1.2 Trial Operation
Try this step only after careful inspection as mentioned in the clause
5.1.1. While in trial operation, it is suggested that the motor has vacant
load to avoid damage to this mechanical equipment arising from incorrect
operation. During trial operation, if the operating instruction is F0.04,
then the RUN/STOP key control (factory default setting) of the operator
panel must be selected. The trial operation steps must be followed as
shown in the table 5-1 below.

Chapter 5 Operation of Inverter
5.2 Cautions for Operation
All the inverter functions are determined by set parameters. The
parameters of inverter ZVF9V-M series consist of the function codes
F0.00~FA.12, see the detail in Chapter 6 of this manual. The displayed
parameter value of each function code is the factory default value of
the inverter before EX factory, which can be modified by the user
according to his needs. It is noteworthy that a user shall change the
relative function parameters when he amends a parameter because
some of the parameters are inter-related. It is not recommended to
modify the set parameter value if there is no special requirement, for
the factory default setting has been done properly. Otherwise, this may
cause damage to the inverter or equipment due to error parameter.
In case there is an error alternation of the parameter, please initialize
the parameter with reference to the operation method in the clause
4.1.5 Parameter Initializing Restoring Factory Default Settings .
HAZARD
WARNING
Do not open the front cover while the inverter is powered ON.
Otherwise, there is the danger of electric shock.
Do not touch the inner side of the inverter while the power is
ON, nor put any foreign matter, i.e., rod or other matter inside
the inverte r. Otherwise, it may result in serious damage to the
equipment or death to personnel.
Do not operate the inverter with wet hands.
If Retry Mode is set, please put a warning sign like "KEEP
CLEAR" or "HAZARD" in an eye-catching place before the
equipment to avoid sudden restart of the equipment after a trip
stop that may result in injury to personnel.
If the inverter runs at a frequency higher than 50Hz, DO confirm
it is within the speed range acceptable by your motor bearing
and mechanical device. Otherwise, there is the danger of
damage to the motor.
Derating should be done before use due to less effective of heat
dissipation when a general motor runs at a low frequency. If
it is a constant torque load, then a forced method or a special
variable frequency motor should be used to release heat.
-34-
Chapter 5 Operation of Inverter
WARNING
DO cut off the power supply of an inverter set aside for a long
time to avoid foreign matter or other things enter in it which
may cause damage to the inverter or even lead to fire.
CAUTION
If the inverter is used beyond the range of allowable working
voltage, then an extra step-up or step-down voltage transformer
shall be configured.
Due to thin air in a place where the altitude is higher than 1,000m,
heat dissipation of the inverter will be less effective. Hence
derating should be performed before use. In general, when t he
height rises by 1,000m, the rated voltage of the inverter shall be
reduced by 10%.
FORBIDDEN
DO NOT touch the radiator or charging resistor of the inverter
with hand(s). Otherwise, there is the possibility of getting scalded.
DO NOT proceed direct start-stop operation frequently with a
contactor or any other switch devices in the inverter input side.
As large charging current exists in the main circuit of the inverter,
frequent power-on/off may produce cumulative effect resulting
in heat fatigue of inverter components and great reduction of
service life of the inverter.
COMPULSORY
In case abnormalities occur, such as smoke, off odor, strange
sound and so on, DO cut off the power supply immediately,
overhaul the equipment or turn to the agent for help via phone
call.
WARNING
The contactor KM1 and KM2 must be designed in interlocked
manner to realize converting between power frequency and
variable frequency.It is forbidden to close synchronously.
Otherwise,it may lead to permanent damage to the inverter.

6.2 Detailed Description on Function Parameters
F0 Series Basic Operation Parameters
F0.00 Control Mode Setting Setting Range: 0~1 Factory Default Setting: 1
This function is used to select the inverter's control mode.
0: Open-ring Vector Control
This is also called "SVC", indicating no speed sensor vector control,
which is applicable to high performance speed regulation without installing
an encoder.
1: V/F Control
This is applicable to the speed regulation where there are no high requirements
for the speed control precision, low frequency torque and other performances,
and can be used when several motors are driven by an inverter.
-58-
Tips
If vector contr ol mode is selected, it is necessary to learn the
motor parameters before the first operation to get the exact
motor parameters. Be sure the nameplate data of the motor
conforms to the motor parameters of the inverter before selfstudy. Otherwise, self-study can not be accomplished or error
results will be turned out. If the nameplate data of the motor
can not be received, then V/F control mode is suggested.
If vector control mode is selected, be sure to set proper
parameters (F1.14, F1.15) for speed regulator to ensure a
good stability and dynamic performance.
If vector control mode is selected, one inverter can drive
only one motor and there is not too much gap between the
inverter capacity and the motor capacity. Otherwise, the
control performance may fall or the machine can not run
normally.
F0.01 Frequency setting mode selection Setting range: 0~8 Factory default setting: 1
This function is used to select the operation frequency setting mode of
the inverter.
0: Operator panel potentiometer setting:
To regulate the operation frequency by operating the potentiometer on
the keyboard.
1: Digital setting,1, operator panel / key or digital encoder setting:
To set the operation frequency by F0.03. The operation frequency can
be altered by pressing the keyboard button or by digital encoder. The
modified frequency value will be stored into F0.03 after powe r down.
If the frequency is not expected to be saved, just set the para meter F0.02
directly.
2: Digital setting 2, external terminal UP/DOWN setting:
To alter the operation frequency through ON/OFF of external control
terminal defined with UP/DOWN frequency function. When UP-COM
closes, frequency rises; when DOWN-COM opens, frequency falls; when
UP/DOWN closes or opens with COM simultaneously, frequency remains
-59-
Chapter 6 Description of Function Parameters
and will not be ch anged. The modified frequency value will be stored into
F0.03 after power down.
The velocity ratio of operation frequency to be modified by UP/DOWN
terminal can be set by parameter FA.05.
3: Digital setting 3, 485 COM setting:
To set the operation frequency by frequency command of RS485
communication interface received from the upper (host) machine.
4: External analog voltage signal AVI (0~10V) or external potentiometer
setting:
To set the operation frequency by external voltage input terminal AVI.
Refer to F5.00~F5.01 for relevant settings.
5: External analog current signal ACI (0~20mA) setting:
To set the operation frequency by external voltage input terminal AVI.
Refer to F5.02~F5.03 for relevant settings.
6: External terminal impulse (0~10KHz) setting:
To set the operation frequency by X6 terminal input impulse signal.
Refer to F5.04~F5.05 for relevant settings.
7: Combined setting:
The operation frequency is set by linear combination of each setting
path. The combination mode is decided by F5.15~F5.16.
8: External terminal selection
To confirm the frequ ency input path by 8 kinds switching assembli es
of external multi-function terminals. The function termina l is defined
by F4.00~F4.05. The path corresponding to the combination is shown

Tips
If the operating keyboard provides a digital encoder, it can
substitute the function of / and ENTER keys to re alize
regulation of digital frequency, modification of parameters
and store of data. Therefore, when using the function of this
digital encoder, F0.01 shall be set to 1 instead of 0. Otherwise,
the frequency setting by digital encoder will be invalid. If the
user needs an analog potentiometer to realize frequency setting,
do use an analog potentiometer keyboard or an exte rnal
potentiometer.
If the frequency setting mode is selected to 6, be sure to select
port X6. Others ports are invalid.
If the frequency setting mode is selected to 8, it is applicable
to the occasion of frequency path real-time shifting. E.g., if
there is a need to realize shifting of voltage setting to current
setting, it can be realized by shifting two combinations: the
multi-function terminal "100" and "101". Also, this can b e
realized by the multi-function terminal defined with "frequency
shifting to ACI" directly.

Chapter 6 Description of Function Parameters
Torque lifting voltage ch anges as the rotator current changes. The larger
the rotator current is, the larger voltage is lifted. If auto torque lifting is
set, magnetic circuit saturation caused by overlarge lifting voltage when
the motor has a light load can be prevented and overheat can e avoided
when the motor is in low frequency operation.
The formula for auto torque lifting voltage is shown below:
Lifting voltage= (F0.12 200) F0.09 (Inverter output current
inverter rated current)The calculation method for hand-operated torque
lifting voltage is similar to auto torque lifting.
The difference lies in that hand-operated torque lifting voltage s hould
remove the ratio of output current to rated current. The torque value shall
be moderate in accordance with loads.
F0.12 Torque lifting selection Setting range: 0.0~30.0% Factory default setting: as per spec.
Excitation voltage falls in the zone of low frequency rotati on. So, it is
necessary to compensate excitation current of the motor and enhance the
torque in the state of low frequency rotation (improve V/F characteristic).
This parameter can not be changed at will. O therwi se, the re
will be error display of the inverter's current, causing abnormal
operation.
CAUTION
F0.11 Torque lifting selection
Too high torque lifting may result in over-current protection of
the inverter which may lead to failure starting of the motor. When
this occurs, the setting value shall be decreased properly.
Setting range: 0~1 Factory default setting:0
This parameter is used to lift motor's low frequency torque characteristic
under V/F mode. It will be invalid under vector control.
0: Hand-operated
Torque lifting voltage is set by parameter F0.12, and the voltage will rise
according to the value set by F0.12.
1: Auto
Torque lifting volta ge changes as the rotator current changes. The larger
the rotator current is, the larger voltage is lifted. If auto torque lifting is
set, magnetic circuit saturation caused by overlarge lifting voltage when
the motor has a light load can be prevented and overheat can e avoided
when the motor is in low frequency operation.

WARNING
Heat dissipation will be less effective when a motor runs at a
low frequency for a long period. Oversetting of to rque lifting
value in this case may speedup this phenomena and lead to
burnout of the motor. DO keep in mind to take a forced method
to release heat from the exterior of motor or perform deratin g
before use.

Chapter 6 Description of Function Parameters
During actual rotation, a motor's slip is influenced by variation in load
torque, which causes deviation of actual speed from the expected value.
With slip compensation function, the inverter's output power can be
adjusted automatically with load torque fluctuation of the motor, which
can compensate off-speed arising from load fluctuation of the motor
and thus improve accuracy of speed.

0: Constant torque
This indicates the inverter's output voltage is of positive ratio to

1: Decreased torque curve 1
This indicates the output is a 1.7 power decreased torque curve.
2: Decreased torque curve 2
The output is the second power decreased torque curve.6-5.Cu rve 2
and 3 are app licable to fa ns, pum ps and oth er variable torque
loads. Curve 3 has better effect on energy saving comparing with
Curve 2. Noteworthy, when the motor runs according to curve 2 and
curve 3, unsteady operation may occur because the motor is in a state of
under excitation. Hence it is necessary to s et the curve as per detailed
conditions. Or adopt a self-defined V/F curve.
3: Self-defined V/F curve
When selecting this mode, just set the expected V/F curve through
F0.17~F0.22.
The above parameter groups are electrical parameters for the motor being
controlled. If the inverter is not matched with the motor power rate (the
gap shall not exceed two specification grades), it is still necessary to
ensure the motor's rated current input be set to F1.01, so as to guarantee
the accuracy of parameter detection of the controlled motor and get a
better control effect.

The above parameters are used to set basic frequency of the motor. The
followings are necessary parameters for vector control.
This software c ontains a parameter group for a standard four-pole motor
and this parameter is already the default one. But this parameter is not
always in full accord with actual electrical parameter for the controlled
motor. To get a good control effect and exact motor parameter, it is
suggested to adopt the motor parameter self-learning function.
Once the motor's self-learning is completed, parameter F1.05~F1.08
will be renewed conditionally.
Before preceding the function of self-learning, DO confirm
parameters on the motor's nameplate are correctly entered.
If the motor capacity does not match the inverter, yet
perform operation in vector mode without having motor's
self-learning, it may lead to the inverter's out of control.
Chapter 6 Description of Function Parameters
F1.11 Motor pre-excitation selection
Setting range: 0~1 Default setting: 0
If the motor is in the state of halting before it is started, it is supposed to
build air-gap flux to get enough starting torque.
0: Conditionally valid
If this choice is selected, the motor will perform pre-excitation when
the motor is started, sustain for a period of time set by parameter F1.12
and then proceed acceleration; or it will proceed control through multifunction terminals defined with starting pre-excitation command (remained
temporarily).
1 Always valid
When the inverter is started, it performs pre-excitation function over
the motor (always sustain 0.00Hz).
F1.12 Motor pre-excitation sustaining time Setting range: 0.1~1.0s Default setting: 0.2s
This parameter defines pre-excitation sustaining time of the motor in the
mode of vector control. In this state, rated pre-excitation current passes
throug h the mot or, as if the motor is in the state of DC braking. Therefore
in the mo de of vec tor contro l, DC braking is invalid. To realize the effect
of DC braking, user may regulate the function of pre-excitation and its
sustaining time.
F1.13 Motor parameter self-learning
Setting range: 0~1

Proceeding vector control over no speed sensor, this parameter is used
to adjust motor's stability precision. Increase this parameter when the
motor has heavy loads with lower speed and decrease this parameter
vise versa.
0: No action
This indicates there is no action of static self-learning.
1: Static self-learning
If motor parameter self-learning is selected, press the RUN key, selflearning of the motor will be started. This course can be finished
automatically without any manual intervention. During self-learning, the
inverter does not respond to other operation commands. After parameter
self-learning is completed, this parameter will be cleared automatically
and the motor parameter received from self-learning will be saved in the
inverter's control panel. In other words, parameter F1.05~F1.08 will be

Tips
If over current occurs during parameter self-learning, please
check if the mo tor's current matches with the inverter's rated
current. Before parameter self-learning, DO make sure the motor
is in the state of stop, otherwise self-learning cannot perform
normally. The advantage of static self-learning is that motor

Parameter F1.14 and F1.15 are valid only for vector control and invalid
for V/F control.
Increasing proportional gain may quicken dynamic response of the
system, but over-large may cause oscillation; Decreasing integral time
may quicken dyn amic response of the system, but over-small may cause
system's severe over-control and oscillation. Generally, it is suggested to
increase prop ortional gain a s much as possible on the premise that there
is no oscillation of the system, and then adjust the integral time to enable
a faster dynamic response and a moderate over-control of the system.

Do take full cons ideration of the relationship between manometer range
and its output feedback signal when setting this parameter in a constant
closed-loop water supply system. Generally, its calculating formula is:
Feed digital quantity setting = 10.00V manometer range required
pressure value Eg. If the manometer range is 12Mpa and required
pressure setting value is 6Mpa, then the feed digital quantity setting shall
be 6.00V instead of 5.00V.
F6.04 Feedback path gain
Setting range: 0.01~10.00
Default value: 1.00
If the feedbac k quantity is not in accord with the actual target value, then
this parameter can be used to regulate the PID value till it is in accord
with the request.
F6.05 Feedback path polarity
Setting range: 0~1
0: Positive:
This indicates the maximum feedback
quantity corresponding to the maximum
input signal.
1: Negative:
This indicates the maximum feedback
quantity corresponding to the minimum
input signal. Refer to Fig.6-13 for details.
Default value: 0
Chapter 6 Description of Function Parameters
F6.06 Proportional gain P
Default value: 1.00
Proportional gain (P) decides response degree of output frequency to
deviation. The g reater the P value is, the quicker response is, but excessive
value of P may result in oscillation and too low value of P may lead to
response lagging.
F6.07 Integral time constant Ti Setting range: 0.0~200.0s Default value: 10.0s
Integral time constant decides the proportional relation between output
frequency change speed and deviation. The function o f integral is to
integrate the output value in accordance with deviation to compensate
deviation between feedback value and set value. Too long integral time
may result in slow response to external disturbance. The shorter the
constant time is, the quicker the response spe ed is, but too short integral
time may result in oscillation.
Feedback quantity
F6.08 Differential time constant Td Setting range: 0.0~10.0s Default value: 0.0s
Positive
The function of differential is to proportionate output frequency to
deviation, and respond timely to abruptly changing deviation. The longer
the differential time is, the faster decay of system oscillation arising from
proportional action is, but too long differential time may result in
oscillatio n. Vise versa, the shorter the differential time is, the less decay
of oscillator is. If F6.08=0.0, differential will be invalid.

F6.09 Sampling period T Setting range: 0.01~10.00s
Default value: 0.00s
Sampling period refers to the cycle in which the system conducts sampling
over feedback quantity. PID regulator makes a calculation in each period
of sampling and gets the output value of PID regulation. The longer the
sampling period is, the slower the response is. If F6.09=0.00, the sampling
period will be finished automatically.

Chapter 6 Description of Function Parameters
Deviation limit refers to the maximum value of deviation between feedback
quantity and set quantity within allowable range of the system. When the
difference (modulus) between feedback quantity and set quantity is lower
than this set parameter value, PID controller will be disabled, as shown
in Fig. 6-23.
Proper setting of this parameter is of advantage to improve the stability
of the output of system which needs to avoid frequent regulation though
it has no high requirement on control precision.

Description on the functions of operation modes
1: Single cycling
Multi- speed operation of the inverter stops automatically after a cycle
and starts only if the operation command is given ag ain. E.g., suppose
the operation time at a stage is 0, then the inverter will skip to the next
stage directly, as shown in Fig.6-26.

T1 T7 refers to the operation time at stage 1 7 separately.
a1 a6 refers to acceleration time at stage 1 6 separately.
d3, d5 and d7 refer to the deceleration time at stage 3, 5 and 7 separately.
2: Continuous cycling:
This indicates the multi-speed operation of inverter recycles repeatedly
and stops only if stop command is given, as shown in
3: Maintaining the ultimate value after singe cycling
After finishing a single cycling, the inverter will run according to the

This parameter defines the inverter's pre-operation frequency and operation
time before PID puts into real operation when PID control is enabled.
In some control systems, the inverter shall output forcefully a certain
frequency value F6.11 to the preset time F6.12 according to this parameter
setting so that the controlled object will reach the preset value instantly.

This parameter group only defines operation time. So multi-speed
acceleration/deceleration time should be converted.
Multi-speed acceleration/deceleration time
Current multi-speed frequency
initial multi-speed frequency
Basic operation frequency
acceleration/deceleration time 1 (F0.14, F0.15)
Eg. If basic operation frequency is 50Hz, acceleration t ime is 10s and
deceleration time is 20s, then the acceleration time of the system in
multi-speed operation operated from 20Hz to 30Hz is
T1={ (30Hz-20Hz) 50Hz} F0.14=2s
The deceleration time when the system operated from 30Hz to 10Hz is
T1={ (30Hz-10Hz) 50Hz} F0.14=8s
4: Wobble Control
The output frequency of the inverter changes periodically during the
preset accelerating /decelerating time. This function is especially applied
to textile and chemical fiber system in which rotation speed changes due
to differential diameter in the front and at the back of a bobbin, as shown
in Fig.6-25.

Setting range: 0.00~upper limit frequency Default value:10.00Hz
F7.13 Wobble preset frequency waiting time
Setting range:0.0~3600.0s Default value: 0.0s
Preset frequency refers to operation frequency of the inverter before it
enters into wobble operation or separated from wobble operation. If
parameter F7.00=004, the inverter will enter into wobble oper ation a t
preset frequency directly after it is started. Then the inverter will enter
-103-
Chapter 6 Description of Function Parameters
into the mode of wobble operation after the waiting time for wobble
preset frequency is finished. If terminal hand-operated input is selected,
F7.13 will be invalid.
If the hundreds digit of the parameter F7.11 is set to "0", then wobble
operation will restart after halting, wobble preset frequency will be
invalid and the system will run in the state memorized before shutdown.
If it is set to "1", then wobble operation will be started after each halting
and the frequency will be started at the preset wobble frequency. The
thousands digit of F7.11 decides
whether to save previous operation info for wobble start or not when the
power is switched on after power failure. If the store is valid, then the
hundreds digit of parameter F7.11 decides whether the first start will be
started at the wobble preset frequency. If there is a decision not to save
the info, then the first operation will be started at th e wobble preset
frequency once the power is switched on. Besides, the wobble status will
be reset by multi-function terminals defined with w obble opera tion
status reset.
F7.14 Wobble amplitude range Setting range: 0.0~50.0% Default value: 10.0%
This parameter refers to the percentage of wobble range. If fixed wobble
range is selected, then the actual wobble value will follow the formula
below:
Wobble range=F7.14 upper limit frequency
If variable wobble range is selected, then the actual wobble range wil l
follow the formula below:

F7.16 Wobble period Setting range: 0.1~3600.0s
This parameter is used to set the period for wobble operation.
F7.17 Time for triangle wave rise Setting range: 0.0~100.0% Default value: 50.0%
This parameter defines the operation time for wobbulation from the lower
limit to the upper limit, which is also the acceleration time in a period of
wobble operation. Its formula is shown below:
Actual time for triangle wave rise =F7.17 wobble period
It is sure that the difference of time between wobble period and triangle
wave rise is the time of fall for triangle wave.

Default value: 10.00Hz
This parameter refers to the reference value of wobble center for inverter's
output frequency when there is a wobble operation.

and the setting frequency decided by external frequency setting path
F0.01. Its formula is shown below:

This parameter is used to identify the local inverter's a ddress which is
unique when an inverter communicates with other inverters or upper
machines through COM port.
If this parameter is set to "0", the local inverter under linking control
will act as the main station, which decides the operation of other inverters
connected to it.
If this parameter is not set to "0", the local inverter will act as a secondary
receiving commands and data from the upper machine or the inverter
acting as the role of main st ation. The inverter receives only commands
and data from the upper machine or the main station in accord with
marked address.

F8.02 COM over time checkout time Setting range: 0.0~ 100.0s
Default value: 10.0s
If correct data signal is not received by the local machine within/exceeding
the interval de fined by this parameter, then communication error will be
judged by the local machine. Hence, the inverter will decide whether to
stop running or maintain the current state according to the treatment
method of communication failure.
F8.03 Local machine response delay time Setting range: 0~1000ms

This parameter defines the delay time that the local machine delivers the
response data frames to the upper machine after the local machine accepts
correctly the information codes from the upper machine.

If local inverter is set to be controlled by master inverter and the setting
frequency of local machine is given by the master inverter, then this
parameter is used to set weight coefficient of frequency instruction
received by the local inverter which acts as a secondary through RS485

the product of local parameter value and the frequency setting instruction
value received through RS485/232 port.

Group F9 Protection Parameters
F9.00 motor overload protection coefficient Setting range: 30~110%
Default value: 105%
If the inverter's driving power rate matches the motor, the motor overload
protection coefficient can be set to 100%. If the output current is smaller
than or equivalent to 150% of the inverter's rated current at this time, then
motor protection is not validated, because inverter's overload protection
precedes over action, as shown in Fig.6-15.

Default value: As per spec.
This parameter stipulates the lower limit voltage allowed by DC bus bar
when the inverter is in normal operation.
overload protection curve
CAUTION
If the grid voltage is too low, the output torque of the motor
will decrease. As for constant power rate and constant torque
load, ultra-low grid voltage will increase the inverter's input
or output current. So the inverter should be derated if it is
operated at low grid voltage for a long term.
F9.02 Over voltage protection level Setting range: 330~760
Default value: As per spec.
Fig.6-15 Inverter Overload Protection Curve and Motor
Overload Protection Curve
If the inverter capacity is larger than the motor capacity, to perform
effective overload protection of load motors with different specifications,
it is necessary to set proper overload protection coefficient fo r each type
of motor and restrict the maximum current value within the allowable
output range of the inverter, as shown in Fig.6-16.
This parameter defines the voltage vector protection threshold of the
motor during deceleration. If DC side pump-up voltage inside the inverter
excesses the value set by this parameter, the inverter will adjust the
deceleration time to delay falling or even stop falling of output frequency.
It will not perform the action of deceleration again till the bus bar voltage
is lower than the over-voltage limiting level. Shown in Fig.6-17.

F9.03 Current limiting level
Setting range: 120~220%
Default value: 180%
This parameter defines current limiting level. During acceleration, the
inverter will adj ust its acceleration time automatically when output
current of the inverter surpasses the value stipulated by this parameter.
When the current falls to this level, just continue to accelerate to target
frequency value. During constant speed operation, if the inverter's output
current exceeds the value stipulated by this parameter, the inverter will
adjust its output frequency to limit the current within the range to avoid
current trip. The default setting for this parameter is that the function of
auto current limiting is always valid during the whole process.

can be used to avoid fluctuation near zero point, as shown in Fig.6-33.
Take the example of analog voltage input path AVI:
Once the operation command is ordered, if the parameter (FA.00, FA.01)
is not set, the output frequency will output in strict accordance with the
correlation between analog voltage and frequency. Once FA.00 and FA.01
setting is done, if the corresponding input AVI does not reach the
frequency A.00+FA.01, the inverter will not run till the corresponding
input AVI reaches the frequency FA.00+FA.01. Then the motor will
begin the starting and accelerate to the frequency value corresponding
to AVI in the preset acceleration time. During deceleration, the inverter
will not stop when the frequency reaches FA.00+FA.01. It will stop only
when the setting frequency corresponding to AVI reaches or is lower
than FA.00.By using this function, inverter's sleep function can be
performed and energy-saving can thus be realized.
FA.02 Energy consumption dynamic braking initial voltage
Setting range 300~750V Default setting As per spec.
FA.03Energy consumption dynamic braking proportional action
Setting range 10~100%
Default setting As per spec.
This parameter defines frequency's zero characteristic. If analog signal
is used to set the frequency, the inverter's output will be interfered due
to instability of analog signal. The lagging function of this parameter
This function defines action para meters for inverter's built-in braking
units. If the inv erter's inside DC-voltage is higher than dynamic braking
initial voltage, then the built-in braking units start action. If a braking
resistor is connected at the moment, DC voltage will fall after a rise
through a braking resistor which releases DC voltage pumping-up inside
the inverter. When DC voltage falls to a certain value, the inside braking
units of the inverter will shut down.
Dynamic braking proportional action is used to define average voltage
value applied onto braking
resistors wh en braking uni ts start action. The braking resistor voltage is
the voltage pulse width modulation wave, whose duty ratio is equivalent
to braking action ratio. The larger value the proportional action i s, the
faster the energy releases, the more obvious the effect is and the larger
power rate consummated by braking resistors. Therefore, user may set
this parameter with full consideration of the braking re sista nce va lue,
power rate and expected braking effect.

8.1 Inspection and Maintenance
The following influences may lead to latent failure of the inverter such
as ambient temperature, humidity, dust, vibration, as well as device
ageing, wear and other causes of the inverter itself during long-per iod
operation on industrial occasions. So it is necessary to perform daily
and periodic inspections and maintenance on the inverter.

Wait at least 5 minutes after turning OFF the input power
supply before performing maintenance or an inspection.
Otherwise, there is the danger of electric shock.
Make sure to open the front panel only after the indicator on the
control keypad turns OFF and verify the charge indicator at the
right side of main loop terminal is OFF after the panel is opened.
Do use an insulated appliance while performing check and do
not operate the equipment with wet hand(s) to avoid unexpected
accidents.
Always keep the equipment clean so that dust and other foreign
matter does not enter the inverter.
Keep electronic equipment away from moisture and oil. Dust,
steel filings and other foreign matter can damage the inverter,
causing unexpected accidents, so do take special care.

The wearing parts of inverter mainly include cooling fan and filter
electrolytic capacitor. Usually, a cooling fan's service life is 20,000~30,000
hours and an electrolytic capacitor's service life is 40,000~50,000 hours.
User can decide when to replace these parts according to the corresponding
operation time.
1.Cooling Fan
It is advisory to replace the fan when abnormal noise or even vibration
occurred to the fan due to bearing wear and fan blade aging. The standard
replacement age is 2~3 years.
2.Filter Electrolytic Capacitor
The performance of filter electrolytic capacitor is subject to the pulsating
current of main circuit. High ambient temperature or frequent load jump
may cause damage to the filter electrolytic capacitor. Generally, every
10 rise in tempe rature may lead to reduction of the capacitor's service
life by half (as shown in Fig. 8-1). If there is any electrolytic leakage or
safety valve emission, just replace it at once. The standard replacement
age for electrolytic capacitor is 4~5 years.

8.3 Storage of Inverter
Please pay attention to the following points if an inverter is set aside or
stored for a short/long period:
CAUTION
DO not keep the inverter in a place with high temperature,
humidity, heavy dust, metal shavings, corrosive gas and vibration,
and ensure a good ventilation.
Long-term idle of the inverter may cause decreasing in filter
characteristic of the electrolytic capacitor. So it should be
recharged within half an year and the recharging period should
be at least 2 hours. DO raise the voltage gradually by using a
voltage regulator to some rated value before it is recharged. At
the same time, check whether the inverter's function is normal
or not, whether there is a short circuit caused by some problems.
In case the above problems occur, just remove or seek servic e
as soon as possible.
