Confirmations Upon Delivery

Notice

1． Never install an inverter that is damaged or missing components. Doing so can result in injury.

 Installation

Notice

1. Always hold the bottom of the inverter when carrying it. If the inverter is held by the front cover, the main body
of the inverter may fall, possible resulting in injury.

2. Attach the inverter to metal or other noncombustible materials. Fire can result if the inverter is attached to a
combustible material.

3. Install a cooling fan or other cooling device when installing more than one inverter in the same enclosure so that

the temperature of the air entering the inverters is below 45℃. Overheating can result in fires or other accidents.

 Wiring

Danger

1. Always turn off the input power supply before wiring. Otherwise, an electric shock or fire may occur.

2. Wiring must be operated by an authorized person qualified in electrical work. Otherwise, an electric shock or
fire may occur.

3. Make sure to ground the ground terminals. Otherwise, an electric shock or fire may occur.

4. Always check the operation of any emergency stop circuits after they are wired. Otherwise, possibly result in
injury ( user responsibility for the wiring).

5. Never touch the output terminal directly by your hands or let the output terminals to come into contact with the
inverter case. Never short the output terminals. Otherwise, an electric short or ground short may occur.

6. Never touch the internal circuit or the zero-component until power off and the charge indicator is off as
there may still be high voltage inside the AC motor dirver.

Notice

◎ Safty Precautions ◎

VB3/V5/VB5 series inverter

1． Confirm that the voltage of the main AC power supply satisfies the rated voltage of the Inverter. Injury and fire

may occur if the voltage is not right.

2． Do not perform voltage withstand tests on the Inverter. Otherwise, semiconductor elements and other devices

can be damaged.

3． Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples.

Otherwise, a fire may occur.

4. Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.

5. Do not connect AC power to output terminals U, V, and W.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

6. Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.The Inverter may be
damaged or internal parts burnt if these devices are connected.

7. Do not connect electromagnetism switch, electromagnetism contactor to output circuit. When the inverter is
running with load, the electromagnetism switch and electromagnetism contactor will generate inrush current
which will cause inverter’s over current protection.

8. Do not disassemble the whole front cover as disassembling the top front while wiring is ok. Otherwise, inverter
internal parts may be damaged.

 Maintenance and Inspection

Danger

1． Do not touch the inverter terminals, as they may carry high voltage.

Otherwise, an electric short may occur.

2． Make sure to have protective cover .Always have the protective cover in place when power is being supplied to

the Inverter. When attaching the cover, please with the power turns off.
Otherwise, an electric short may occur.

3． Maintenance, inspection, must be performed only by authorized personnel.

Otherwise, an electric short may occur.

Notice

1. A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully. The CMOS IC can
be destroyed by static electricity if touched directly.

2．Do not change the wiring, or remove connectors or the Digital Operator, during operation.

Otherwise, The devices may be damaged.

 Constant torque low speed running

When the inverter outputs to a common motor at low speed for a long term, the output rated torque should be derated due
to the worsening radiating effect. If low speed constant torque long term running is required, then a special variable fre­quency motor is needed.

 Motor insulation

When using the V5/F5 series inverter, make sure to confirm the insulation of the motor which will be used to avoid device
damage. Besides, do the periodic check for the insulation condition of the motor located in the bad environment to guaran­tee the system can operate safely.

 Negative torque load

If in the case of improving load, negative torque may occur. Braking units should be connected with the inverter, or over
current and over voltage fault may happen.

◎ Usage Precautions ◎

 Mechanical resonance point of load

The inverter may encounter the mechanical resonance point of load within certain output frequency range. Jump frequen­cies have to be set to avoid it.

 Capacitor and resistor

Because the inverter output pulse wave, capacitor and resistors shouldn't be connected with the output terminals of the in­verter, or the inverter may trip or components may be damaged; Besides, don’t connect switch components such as air
switch and contactor with the output terminals is recommended, as shown in Fig.0-1(If switch components need to be
connected with the output terminals, make sure output current of the inverter is zero when switch is acting).

Fig.0-1 Capacitor is prohibited to be connected with

output terminals of inverter

 Derate according to basic frequency setting

When the basic frequency is lower than the reference frequency, please consider duration for the motor so as to avoid mo­tor’s damage caused by overheating.

 Running at frequency above 50Hz

If running at frequency above 50Hz, besides the increment of vibration and noise, the ranges of running speed of motor
shaft and mechanical device have to be guaranteed. Be sure to make an enquiry first.

 The electro-thermal protective value of motor

If the applicable motor is selected as per requirements, the inverter can perform the thermal protection to the motor. If the
ratings of applied motor are not in compliance with the inverter, be sure to adjust the protective value or adopt other pro­tective measures to guarantee the safe running of motor.

 Altitude and derate

When the altitude is higher than 1000m, the cooling effect of inverter is deteriorated because of the rareness of air, deration
must be considered, shown in Fig.0-2 which indicates the relationship between the altitude and rated current of frequency
inverter.

 About protection classes

The protection class of V5/F5 series inverter IP20 is reached in the case of status display unit or keyboard.

When you scrap the inverter, please pay attention to:
Explosion risk of capacitor: The capacitors in the main circuits may explode when they are burned.
Waste gas when plastic parts are burned: Poisonous gas may be generated when front panel is burned.
Dispose method: Please dispose as industrial rubbish.

2-5-4. Connection of communication terminals

The communication port of this inverter is standard RS485 port.
With the following wiring methods, you can build up control system of one-host-one-slave or one-host-multi-slaves. Also,
the superior device (PC or PLC) can realize the functions such as real time monitor inverter, remote control, highly auto­mated motion control.
 Connection of inverter RS485 port and superior device:

Fig. 2-9 RS485-(RS485/232)-RS232 cable connection

 Many inverters can be connected together through RS485, the PLC(or PC) is the host device, as shown in Fig.2-10;

Also, you can select one inveter as host and the other inverters are slaves, as shown in Fig.2-11.The more inverters are
connected, the communication system will be interfered seriously, the following wiring is recommended.

(Inverters and motors are all grounded well)

If the communication is still failed with the above connection methods, you can adopt the following methods:
(1) Use separate power supply for PLC or isolate its power supply.
(2) Use magnetism ring for the cable and reduce the inverter’s carrier frequency.

2-6. Mounting guide according with EMC

As the inverter output wave is PWM, electromagnetic noise will generate while it is working. To reduce the inverter inter­ference for other devices, this chapter introduces the EMC mounting method in the following aspects: control the noise,
local wiring, grounding, leak current, power supply filter.

2-6-1. Control the noise

1. Noise type
The noise made by inverter may affect the neaby equipments and the effection is related to inveter’s control system, anti­noise and anti-jamming ability of the devices, wiring environment, safety distance, grounding method and other fac­tors.The noise contains the following types: electrostatic induction, circuit transmit, space transmit, electro magnetic in­duction and so on.

2. Essential countermeasure for suppressing noise

Table 2-5 solution for control noise

Noise transmit

path

Solution

2

When the ground cable of external equipment forms a loop with the inverter, the equipment may operate incor­rectly caused by leakage current of inverter grounding cable. The problem can be solved if the equipment is not
grounded.

3

If the external equipment shares the same AC supply with the inverter, the inverter’s noise may be transmitted
along its input power supply cables, which may cause interference to other external equipments. Take the follow­ing actions to solve this problem: Install noise filter at the input side of the inverter, and use an isolation trans­former or power filter to prevent the noise from disturbing the external equipment.

(1)The equipment and the signal cables should be far away from the inverter. The signal cables should be
shielded and the shielding layer should be grounded. The signal cables should be located far away from the in­put/output cables of the inverter. If the signal cables must cross over the power cables, they should be placed at
right angle to one another.
(2) Install high-frequency noise filter (ferrite common-mode choke) at the input and output of the inverter to pre­vent the RF interfere of power lines.
(3) Motor cables should be placed in a tube thicker than 2mm or buried in a cement slot. Power cables should be
placed inside a metal tube and be grounded by shielding layer (Motor cable should use 4-core cable, one of the
cores should be grounded near the inverter and another point should be connected to the motor’s cover).

1,7,8

Don’t put the strong and weak electricity cables in parallel or bundle these cables together. Other devices should
also be away from the inverter.The devices wire should be away from the I/O of the inverter. The signal cables
and power cables should be shielded cables. Devices with strong electric field and magnetic field should be away
and orthogonal from the inverter.

2-6-2. Local wiring and grounding

(1) The cable connected inverter and motor (cables from U, V, W points) should not parallel with power supply calbe (R, S,

T or L, N terminal input wire). The distance should be more than 30cm.
(2) Inverter’s output cables from U, V, W terminals is recommend to put in metal tube or slot.
(3) Control signal cables should be shield and the shield layer should be connected with inveter’s PE terminal, then ground

the point near the inverter.
(4) The grounding cable of inverter’s PE terminal should be connected to ground directly.It can’t connect to other devices’

grounding cables.
(5) Don’t put the signal cables in parallel with the power cables (R, S, T or L, N with U, V, W) or bundle these cables to­gether, at least 20~60 cm distance shoule be kept (related with power current), If the signal cables and power cables
needed to be intersected, they should be vertical to each other, as shown in Fig2-12.

Fig. 2-12 Wiring requirement of system

(6) The weak electricity grounding cable such as control signal and sensors should be separated with strong electricity

grounding cable.
(7) Do not connect other devices to inverter’s power input terminals (R, S, T or L, N).

3 Operating Instructions

3-1. Run the inverter

3-1-1. Command channel of inverter

We can control the inverter’s START, STOP, JOG and other running actions by three command channels.

1. Operation panel

Control by , and keys on the operation panel (default setting)

2. Control terminals
FWD, REV, COM can form 2-wire control; one terminal of X1~X6 and FWD, REV can form 3-wire control.

3. Serial port
The operations such as START, STOP can be controlled by other devices which can communicate with the inverter.

You can select the command channels via parameter P0.03 or via multi-functional input terminal (P4.00~ P4.07 function
23, 24).
Warning: The user must debug the system after changing the command channel to make sure it can meet the system re­quirement, otherwise device damage and physical injury will happen.

3-1-2. Frequency setting channel

In common operating mode, there are 8 channels to set the frequency:

0: keyboard analog potentiometer
1: a and keys on the operate panel
2: Function code on the operate panel
3: Terminals UP/DOWN
4: Serial port
5: Analog VI
6: Analog CI
7: Pulse terminal（PULSE）
8: Combination

3-1-3. Running state

There are two running state: stopping and running.
Stopping state: After the inverter powered on and initialized, if no operating command is input, the inverter will enter

standby state.

Running state: The inverter enters running state after it receives running command.

V5 series inverter

27

3-1-4. Running modes

V5 inverter has 5 kinds of running modes which can be sequenced according to the priority: Jog running→Close loop run­ning→PLC running→Multi-speed running→Simple running, as shown in Fig. 3-1.

0: Jog running

When the inverter is in the stopp state, it will running according to jog frequency (refer to P3.06~P3.08 for details) af­ter receiving jog running command (e.g after pressing key)

1: Close loop

If the close loop running function is enabled (P7.00=1), the inverter will enter close loop running mode, that is, ad-

justing PI according to the reference and feedback value (see parameter P7), PI adjuster output is the essential com-

mand of inverter output frequency. Close loop running can be disabled by multi-function terminal (function No.27)

and the inverter will switch to a lower priority running mode.
2: PLC running

If PLC function is enabled (the lowest bit of P8.00≠0), the inverter will enter PLC running mode and run in the

pre-defined mode (refer to parameter P8). PLC running can be disabled by multi-function terminal (funcition No.29)

and the inverter will switch to a running mode with low priority.
3: Multi-speed running

Select Multi-frequency 1~7 (P3.26～P3.32) to realize multi-speed running by no-zero combination of multi-function

terminal (function No.1, 2, 3)
4: Common running

Common running is open loop running mode.

Fig. 3-1 Running state

Except “Jog running”, other 4 kinds of running modes can be enabled with multi-frequency. Besides, “PLC running”,
“multi-speed running”, “common running” can be used as swing frequency.

4-2-6. Protection function parameters (Group P5)

P5.00 Motor overload protection mode selection Range: 0,1 0

This parameter defines the protection mode when overload or overheat occurs.

0: Inverter locks the output. When overload or overheat occurs, inverter will lock output and the motor will free stop.
1: Disabled. Motor has no overload protection. (Be careful to use)

P5.01 Motor overload protection coefficient Range: 20(%) ~120(%) 100(%)

This parmeter is used to set sensitivity of thermal relay protection for inverter load motor. When the output current value of
load motor can not match the rated current of the inverter,the motor can be thermal protected, as shown in Fig.4-30.
Use the following coefficient to calculate.

[P5.01] = × 100

Fig.4-30 Thermal relay protection

Note: When one inverter run with multi-motors, inverter’s thermal relay protection will be disabled. Therefore, please install

thermal relay in the input wire of each motor to protect motor more efficiently.

P5.02 Over-voltage speed loss selection Range: 0, 1 1

0: disable
1: enable

During deceleration, the motor’s decelerate rate may be lower than that of inverter’s output frequency due to the load iner­tia. At this time, the motor will feedback the energy to the inverter, it will cause the inverter DC bus voltage too high. If no
measures are taken, the inverter will be overvoltage protected.

During the deceleration, the inverter detects the bus voltage and compares it with the speed loss over voltage point defined
by P5.03. If the bus voltage exceeds the speed loss overvoltage point, the inverter output frequency will not decrease.
When the bus voltage is lower than the point again, it continues to decelerate run, as shown in Fig.4-31.

Range: 0.00~99.99Hz/s 10.00Hz/s

P5.06

Auto current limiting selection

Range: 0, 1 1

Auto current limiting function is used to limit the load current smaller than the value defined in P0.54. Therefore the in­verter will not trip due to surge over-current. This function is especially useful for the applications with big load inertia or
big change of load.

Auto current limiting level (P5.04) defines the threshold of auto current limiting.The range of it the percentage of the in­verter rated current.

Frequency decrease rate when current limiting (P5.05) defines the rate of output frequency when the inverter is in auto
current limiting status.

If the decrease rate is too small, auto current limiting status may not change and overload fault may occur. If it is set too
big, the frequency will change too sharply and thus the inverter may be in generating status for long time, which may result
in overvoltage protection.

Auto current limiting functions is always enabled in accerlate or decelerate process. P5.06 (auto current limiting) will de­cide if the auto current limiting function is enable when constant speed running.

P5.06＝0, Auto current limiting function is disabled in constant speed operating process;

F5.06＝1, Auto current limiting function is enabled in constant speed operating process;

In auto current limiting process, the inverter output frequency may change; therefore, when the inverter output fre-

quency is required to be stable, this function is not recommended.

P5.07 restart after power off Range: 0,1 0

P5.08 waiting time of restart after power off Range: 0.0~10.0s 0.5s

P5.07 = 0, Restart after instantaneous power off is disabled.
P5.07 = 1, Restart after instanteaneous power off is enabled.

If instantaneous power off (LED shows E-11) occurs when inverter is in running status, after repowering, it will detect
speed automatically and then restart after the waiting time (P5.08). During the waiting time, the inverter will not start even
you input running command. If input stop command, the inverter will release the speed checking and restart status.

P5.09 Auto reset fault times Range: 0~10 0

P5.10 Interval of auto reset fault Range: 0.5~20.0s 5.0s

When the inverter is in running process, it may has fault and stop output by accident for overload fluctuating.To avoid the
pause of the device, you can use auto fault reset function. In the reseting process, inverter will restart after auto-checking
the speed. If the inverter can not reset successfully in auto reset fault times, fault protection will be enabled and output will
be stop. This function will be OFF when auto reset times is 0.
Note: (1) When use this function, make sure inverter has no substantiality fault.

(2) This function is invalid for the fault caused by overload and overheat.

The definition of close-loop value, feedback value, difference limit and proportion/integral parameter in Fig 4-33 are the
same to normal PI definition. Please refer to P7.01~P7.11. The relationship between preset value and expect feedback val­ue is shown in Fig 4-34. The preset value is based on 10V; the feedback value is based on 20mA.

After confirming the system, the procedure of setting close-loop parameters is shown below:
(1) Confirm the close-loop setting and feedback channel (P7.01, P7.02).
(2) The relationship between close-loop setting and feedback value (P7.06~P7.09).
(3) Confirm the close-loop adjustment features (P7.14=1 negative function; 0 is positive function), as shown in Fig4-35.
(4) Set the close-loop preset frequency (P7.16~ P7.17).
(5) Set close-loop filter time, sampling cycle, difference limit and gain coefficient (P7.03, P7.04, P7.12, P7.13).

External setting channel and feedback channel have noise. To filter the channel by setting the filter time P7.03 and P7.04. the
longer the time, the stronger the noise immunity ability. But the reponse will be slow.

P7.05 Digital setting Range: 0.00~10.00V 0.00V

If P7.01=0, the value of P7.05 will be considered as the setting value of close-loop control system. Therefore, modify the value
of P7.05 to change the system setting value when controlling the close-loop system by operate panel or serial port.

P7.12 Sampling cycle T Range: 0.01~10.00s 1.00s

The bigger the proportion gain KP, the quicker the response, but too big may lead to surge easily.
Only adjust with proportiaon gian KP, deviation can not be eliminated, integral gain KI can be used to form PI control to
eliminate the deviation. The bigger the Ki, the quicker the response of changing deviation, but too big of the Ki may lead to
surge easily.
Sampling cycle T is the sampling cycle of feedback value. PI regulator calculates once in every sampling cycle, the longer
the cycle, the slower the response.

P7.13 Limit of deviation Range: 0.0~20.0(%) 2.0(%)

The max deviation value of close-loop setting is shown in Fig.4-37, if the feedback value is in this range, PI regulator will stop adjusting.
This function is useful to improve accuracy and stability of the system.

Note: Define the relationship between setting value and speed.

P7.15 Integral adjustment selection Range: 0, 1 0

0: Stop integral adjustment when the frequency reaches upper limit or lower limit.

1: Continue the integral adjustment when the frequency reaches upper limit or lower limit.

For the system need quick response, it is better to cancel the continue integral adjustment.

P7.16 Close-loop preset frequency Range: 0~upper limit of frequency 0.00Hz

P7.17 Holding time of close-loop preset frequency Range: 0.0~250.0s 0.1s

This function can make the close-loop adjustment enter stable status.
When inverter is in close-loop running mode, it accelerates to close-loop preset frequency P7.16 in acc time, and is running for a
while (P7.17), then runs according to close-loop features. Refer to Fig 4-38.

Note: If no need the function of close-loop preset frequency, please set the preset frequency and holding time to 0.

P7.18 Threshold of PI zero frequency wakeup Range: 0.00~500.0Hz 0.01Hz

P7.19 Backlash of PI zero frequency wakeup Range: 0.00~500.0Hz 0.01Hz

The two function parameters are used to set PI threshold and backlash of zero-frequency wakeup.

If you set the frequency to 0 Hz, PI threshold of zero-frequency wakeup will be disabled.

For example: Fig 4-39:

Fig.4-39 zero-frequency backlash

Start process:

After start command is sent, the motor will start and accelerate to the preset frequency in the Acc time when the setting
frequency reaches or exceeds Fb.

Stop process:

The inverter will not stop immediately if the setting frequency is lower than Fb, only when the setting frequency reaches
Fa, the inverter will stop output.

Fa points to zero-frequency wakeup threshold (P7.18), Fb-Fa points to zero-frequency wakeup backlash (P7.19).

This function can realize domant function and save the energy, besides, the inverter will not frequent start at threshold fre­quency by defining the backlash width.

4-2-10. Swing frequency function parameters (Group P9)

Swing frequency is widely used in textile and chemical fiber industry which need to horizontal move and winding. The
typical application is shown in Fig. 4-45. The swing frequency process: accelerate to the preset frequency of swing fre­quency (P9.02), wait for a while (P9.03), decelerate to center frequency of swing frequency, cycle run according to the
preset swing frequency width (P9.04), jump frequency (P9.05), swing frequency period (P9.06) and up time (P9.07) unitl
the stop command is input.

The center frequency is the preset frequency of normal running, multi-speed running or PLC running.

Auto-cancel the swing frequency when jog or close-loop operation.

PLC runs with the swing frequency, the swing frequency will be invalid when PLC switches the stages. It enters the swing
frequency after accelerating or decelerating to preset frequency according to the acc/dec setting of PLC stage. Stop ac­cording to the acc/dec time setting of PLC stage.

quency status.
1: Terminal manual input mode. If the multi-function terminal (Xi is set to No.25 function) is enabled, the inverter will

enter swing frequency status. If the terminal is disabled, the inverter will quit swing frequency and run at preset swing fre­quency (P9.02).

Ten bit of LED: swing frequency width
0: Variable width. Width AW changes with the center frequency and the changing rate is defined by P9.04.
1: Fixed width. Width AW is decided by max frequency and P9.04.

P9.02 Preset swing frequency Range: 0.00~650.00Hz 0.00Hz

P9.03 Waiting time of preset swing frequency Range: 0.0~6000.0s 0.0s

P9.02 is used to set running frequency before entering swing frequency.
If you select auto start mode, P9.03 is used to set the running lasting time at preset swing frequency before the inverter
enter swing frequency; if you select manual start mode, P9.03 is disabled. Refer to Fig. 4-45.

P9.04 The width of swing frequency Range: 0.0~50.0% 0.0%

Variable width: Aw＝Center frequency×P9.04
Fixed width: Aw＝Max running frequency P0.06×P9.04
Prompt: The swing frequency is limited by upper/lower frequency, it will work abnormal if set uncorrect.

P9.05 Jump frequency Range: 0.0~50.0% 0.0%

As shown in Fig4-45, there is no jump frequency if P9.05 = 0.

P9.06 Swing frequency period Range: 0.1~999.9s 10.0s

It defines the complete period of swing frequency up/down process.

P9.07 Up time of triangle wave Range: 0.0~98.0% 50.0%

Running time of swing frequency up stage ＝P9.06×P9.07(s), Time of down stage＝P9.06×（1－P9.07）(s). Refer to
Fig.4－45.

Note: You can select S-curve Acc/Dec mode along with swing frequency, the swing frequency will run more smoothly.

P9.12 Perimeter of shaft Range: 0.01~100.00(cm) 10.00(cm)

P9.13 pulses per revolution Range: 1~9999 1

These parameters are used to realize fixed length control.
The counting pulses is input via terminal (X6, defined as function 35), and calculate the length according to the pulses per
revolution (P9.13) and perimeter of shaft (P9.12).
Calculated length＝counting pulses÷ pulses per revolution×perimeter of shaft
The length can be corrected through times of length (P9.10) and calibration coefficient of length (P9.11), and the length is
the actual length.
Actual length ＝calculated length×calibration coefficient of length÷calibration coefficient of length
When actual length(P9.09)≥preset length(P9.08), the inverter will send out STOP command.When the inverter restarts, it
needs to clear the actual length (P9.09) or make the actual length (P9.09) less than preset length (P9.08), otherwise the in­verter will not start.
Note: (1) The actual length (terminal Xi is defined to function 36) can be cleared by multi-function input terminal. The
