Description
The inverter is a voltage source type machine and the output
voltage is PWM waves including harmonics. Therefore, the
temperature rise, noise and vibration of the motor will slightly
increase compared with power frequency running.
When the inverter drives common AC induction motor to run at a
low speed for a long term, the output torque maybe reduced due to
the heat dissipation effect of the motor. If it is required to run at a
low speed and constant-torque for a long term, a variable frequency
motor must be used.
When using an adaptive motor, the inverter could perform thermal
protection on the motor. In case that the motor is not matched with
the inverter in rated capacity, the protection threshold value must be
adjusted or other protection must be taken for guaranteeing safe
running of the motor.
In case that the motor runs at the frequency over 50Hz, in addition
to increase of the vibration and noise of the motor, the applied

The gearbox, gears and other mechanical devices needing
lubrication probably be damaged when running at a low speed for a
long term , please inquiry in advance if having questions.
For lift load , negative torque is often generated, the inverter may
trip due to overcurrent or overvoltage, and then a appropriate brake
assembly should be selected.
Within the output frequency range, the inverter may encounter the
mechanical resonance point of the load, now the skip frequency
shold be selected.
Selecting DI terminals to control the start/stop of the inverter. It is
prohibited to use contactors and other switching devices at the input
side of the inverter for direct and frequent start/stop in case of
equipment damage.
When the motor is used for the first time or before the motor is used
again after being placed for a long time, insulation check shall be
conducted to prevent the effectiveness of insulation of a motor
winding in case of the damage to the inverter. Wiring is shown in the
following figure. In the testing process, it is supposed to adopt a
500V voltage type megger and guarantee that the insulation
resistance is not less than 5MΩ.
Since the inverter PWM output waveform, fault trip of the inverter or
damage to devices may be caused if a capacitor or an anti-thunder
piezoresistor installed at the inverter output must be removed.
If a contactor and other switching devices will be used between the
output of the inverter and the motor, please ensure that switch
operation is performed on the inverter whitout running; otherwise,
the inverter may be damaged.
It is not suggested to use the inverter beyond the allowable
operating voltage range, and please use a corresponding voltage
increasing/decreasing device for voltage transformation if needed.

Note： The usage and working conditions needs to be considered
when selecting brake
resistor. The following is a description of brake resistor selection：
（1）Brake Resistor Calculation
When the output current equals half the rated current of the motor, the same braking
torque can be obtained as the rated torque of the motor，so the rough calculation of brake
resistor is：𝑅𝑅𝐵𝐵 =
2∗𝑈𝑈𝐷𝐷
𝐼𝐼𝑀𝑀𝑀𝑀
，𝑈𝑈𝐷𝐷 is brake voltage，𝐼𝐼𝑀𝑀𝑀𝑀 is motor rated current，to ensure that the
inverter is not damaged, the minimum value of the brake resistor is 𝑅𝑅𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 when the
current flowing through the brake resistor is motor rated current. When selecting the
resistance of the brake resistor, it must not be less than the below value.
𝑈𝑈
𝑅𝑅𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 = 𝐷𝐷
𝐼𝐼𝑀𝑀𝑀𝑀
According to the above description, the selection range of brake resistor is：
𝑈𝑈𝐷𝐷
𝐼𝐼𝑀𝑀𝑀𝑀
< 𝑅𝑅 ≤
2∗𝑈𝑈𝐷𝐷
𝐼𝐼𝑀𝑀𝑀𝑀
（2）Brake Resistor Power Calculation
𝑈𝑈 2
The power of brake resistor：𝑃𝑃0 = 𝐷𝐷
𝑅𝑅
The brake resistor power is mainly determined by the brake utilization rate ED%.
Because the braking time of the system is relatively short, the temperature rise of the
braking resistor is not enough to achieve a stable temperature rise.So the principle for
determining the brake resistor capacity is to minimize the brake resistor capacity if the
temperature rise of the brake resistor does not exceed its allowable value (i.e. the rated
temperature rise)，The rough algorithm is as follows：
𝑃𝑃𝐵𝐵 = 𝜆𝜆 ∗ 𝑃𝑃 ∗ 𝐸𝐸𝐸𝐸% = 𝜆𝜆 ∗
𝜆𝜆 = 1 −
|𝑅𝑅−𝑅𝑅𝐵𝐵 |
𝑅𝑅𝐵𝐵

3.7 EMC Precautions
The inverter can produce electromagnetic interference，this interference will affect
automation devices and instruments probably.Correct installation can reduce
electromagnetic nosie of devices and improve the interference resistance . To ensure that
the inverter can run normally for a long time, please refer to the following installation
description.
3.7.1Field Wiring
Equipment classification：When multiple equipment is mounted in a common
enclosure,such as inverter, filter, PLC and detection instrument . According to the
ability in emitting electromagnetic noise externally and bearing noise, the devices are
classified into strong-noise devices and noise-sensitive devices. The same type
equipment shall be installed in the same area. The different type equipment shall be
kept distance of 20cm or above. It is suggested to isolate different areas spatially through
metal shells or grounding partition plates in the enclosure.
Wiring in the enclosure: Main power cables and signal cables are generally
arranged in the enclosure. The signal cables are easy to be interfered by the main power
cables and then cause equipment trip. So, the signal cables and the main power cables
are supposed to be distributed in different areas, not in the same cable tray, it is prohibited
to arrange parallel wiring and alternate wiring of the signal cables and the main power
cables in the close distance of 20cm, and the signal cables and the main power cables
shall not be bound together either. If a signal cable must go across a power cable, a
90-degree angle shall be maintained between the signal cable and the power cable. Input
and output cables of the main power shall not be alternately arranged or bound together.
3.7.2 Noise Suppression and Grounding
The inverter must be grounded reliably in the operating process. Grounding is
conducted for the safety of equipment and people and furthermore provides a simplest
and most effective method with lowest cost for solving EMC problems, thereby deserving
priority in consideration.
Shielding cables shall be adopted for all control terminals of the inverter. The
shielding layer is grounded nearby the inlet of the inverter. Cable clamps are adopted for
- 24 -
NVF5 Series User Manual
Chapter 3 Installation and Wiring
grounding to realize 360-degree circular connection. It is prohibited to twist the shielding
layer before connecting it to the inverter in case that the shielding effect is lowered greatly
or even lost.
A shielding cable or an independent cable tray shall be adopted between the inverter
and the motor. One end of the shielding layer of the motor cable or the metal shell of the
cable tray is connected nearby the inverter, and the other end is connected with motor
shell.
The grounding cable shall be as short and thick as possible so as to lower grounding
impedance, grounding cables shall be far away from the input side and the output side of
noise-sensitive devices.
3.7.3 Leakage Current Suppression
Leakage currents include line leakage currents and grounding leakage currents. The
magnitude of a leakage current depends on distributed capacitance of the system in the
wiring process and the carrier frequency of the inverter. The leakage current can be
effectively lowered by reducing the carrier frequency and using motor cables as short as
possible. When the motor cable is long (50m or above), an AC output reactor or a sine
wave filter shall be installed at the output side of the inverter; when the motor cable is
longer, it is supposed to install one reactor at a certain distance.
Two classification and expression modes of leakage currents are：
Grounding leakage current: means the leakage current flowing through a common
grounding cable. It may flow into the inverter as well as other devices through the
grounding cable. The leakage current may cause malfunction to a residual-current circuit
breaker, a relay or other devices.
Lines leakage current: means the leakage current flowing through distributed
capacitors among the cables at the input side and the output side of the inverter. The
magnitude of the leakage current is relevant to the carrier frequency of the inverter, the
length of the motor cable and the sectional area of the cable. The higher the carrier
frequency of the inverter, the longer the motor cable and the larger the sectional area of
the cable, the larger the leakage current is.

6.2.5 Preset Speed Main Frequency Setting
NVF5 can realize 15 preset frequency at most，assigns 4 digital inputs used to select
as frequency reference.Also can be selected less than 4 DI to configure preset speed，For
missing bits, state 0 is calculated.
When the main frequency reference is preset speed, the function selection of DI
terminal should be set to the value of 24-27, that is, the input terminal of preset speed
should be specified.The Multi-Preset Frequency can be set in parameter group FA，see
below parameter setting：

The scale of preset speed is the percentage of Max. frequency F0.07. The positive
and negative parameters determine the direction of operation. If the value is negative, it
means the inverter runs in the opposite direction.
Assigns 4 digital inputs as preset frequency input channel - K1～K4，and compose 4
F5.01
binary digits：Among them, 1 means effective, and 0 means ineffective.
The state can be combined into 15 states. These 15 states correspond to 15 setting
values.See below figure:

6.2.7 Process PID Main Frequency Setting
Process PID control is a common method of process control. Through proportional,
integral and differential calculation of the difference between the feedback signal and the
target signal of the controlled variable, the output frequency of the inverter is adjusted by
the closed-loop, so that the controlled variable can be stabilized at the target value；
When the PID is used as reference, if the PID forbidden is set at the same time
(terminal function 44), the system will switch to the F9.29 standby channel for regulation.

6.6 Vector Control Parameters
Vector control regulator is divided into speed control regulator and torque control
regulator：Speed control mode is that the whole control takes the stable speed as the core
to ensure that the running speed is consistent with the speed reference, and the maximum
load capacity is limited by the torque limit；torque control mode is the whole control to
stabilize the torque as the core to ensure that the actual output torque and torque
reference consistent, and the output frequency is limited by speed limit.

Speed Loop PI Switch
The speed loop PI parameters are divided into two groups: low speed and high speed，
when the running frequency is smaller than F3.03-Switch Frequency1，speed loop PI
regulated parameters are F3.01 and F3.02，when the running frequency is greater than
F3.06-Switch Frequency2 ，speed loop PI regulated parameters are F3.04 and F3.05.
The speed loop dynamic response characteristics of vector control can be adjusted by
setting the proportion and integration time of the speed regulator. Increasing proportional
gain and reducing integration time can speed up the dynamic response of speed loop.
However, if the gain is too large or the integration time is too small, the system will
oscillate.

This parameter can adjust the accuracy of motor speed stability. When the frequency
of the motor is lower than the output frequency of the inverter, the parameter can be
increased. The adjustment of this parameter will affect the inverter output current of the
same load,when the load capacity is weaker in the low speed, this parameter can be
appropriately increased.

Torque Control Reference
Torque Control Reference is set by parameter F3.19.
When the torque reference is given byAI1、AI2、HDI，the final torque reference is：
AI output percentage of analog curve AI（pulse of HDI curve） × motor rated torque.
AI analog curve、pulse of HDI curve：refer to 6.2.3 Analog Main Frequency Setting

When the torque reference is positive，the inverter run forward，when the torque
reference is negtative，the inverter run reverse.
●
Speed→Torque switch point
In order to avoid the system sudden skip in the start-up process, the inverter firstly
complete the start process in the speed mode, and switches to the torque control mode
when reaching the switching point；
This method can effectively solve the problems of insufficient starting torque and
sudden skip of starting torque in torque mode.
●
Torque control Accel./Decel. time
Torque control Accel. Time F3.24 means acceleration time of torque reference from 0

●
Forward/Reverse speed limit value in torque control mode
Used to set up the positive or reverse maximum operating frequency of the inverter
under the torque control mode.
In torque control mode,If the load torque is less than the output torque of the motor,
the speed of the motor will rise continuously. In order to prevent the mechanical system
from flying accidents, it is necessary to limit the maximum speed of the motor.

The integral regulator of the current loop does not use integral time as dimension, but
directly sets integral gain.
If the PI gain of the current loop is too large, the system may oscillate. Therefore,
when the current oscillates or the torque fluctuates greatly, the Proportional gain or the
Integral gain can be reduced manually.
6.7 OverCurrent Stall Protection
If the current exceeds 150% action current of overcurrent stall (1.5 times of motor
rated current) during the running process, the overcurrent stall will take effect and the
output frequency will begin to decrease, until the current returns below the overcurrent
stall point, the frequency will start to accelerate up to the target frequency, and the actual
acceleration time will be increased automatically. The greater the overcurrent stall gain,
the stronger the overcurrent stall, the faster the output frequency drops.

6.10.1 Monitoring Parameters
Customers can directly monitor the parameters of inverter running state and standby
state through the integral keypad, and can select the display state parameters by the
keypad by setting parameters. The setting of state display parameters are in hexadecimal.
Each of the bit is independent. The values of bits, ten bits, hundred bits and thousand bits
should be set separately. At this point, the binary value should be determined first, and
then the binary number is converted to hexadecimal number. The following figure shows
the correspondence between LED and display parameters with parameter F7.05 .Please

A.4.1 RTU Mode
In RTU mode, the bigger one between the function code and Modbus internal
convention value is taken for the free time between frames. The minimum free time
between frames internally agreed by Modbus is as follows: free time of frame head and tail
is not less than 3.5-byte time to define the frame. Data check adopts CRC-16; the whole
information participates in the check; upper and lower bytes of the checksum should be
sent after exchange. Refer to the examples following the reference protocol for the specific
CRC check. Note, at least 3.5-character Bus free time should be kept among frames; Bus
free among frames does not need to accumulate the start and end free.

A.8 Network Wiring
A.8.1 Topology structure
RS-485-Modbus repeater is not configured. There is a trunk cable which is directly
connected with all devices (daisy-chained) or connected through short branch cable.
Trunk cable, also known as Bus, may be very long. The termination resistor must be
connected at the each end of the network cable. Also the repeater can be used among
multiple RS-485 Modbus. And each slave address in the network is unique, which is the
basis for guaranteeing Modbus serial communications.
A.8.2 Length
End-to-end length of the trunk cable must be limited. Maximum length is related to
Baud rate, load quantity on the cable (specification, capacitance, or characteristic
impedance) and daisy chain and network configuration (2-wire or 4-wire system).
Branches must be short and cannot exceed 20m. If multi-port splitter with n branches,
the maximum length of each branch must be restricted to 40m divided by n.
A.8.3 Grounding Mode
“Network Common” circuit (common end of the signal and optional power supply)
must be directly connected to PE ground. It’s better that the whole Bus is grounded in a
single point. Usually, this point is optional on the master or its splitter.
A.8.4 Cable
Modbus cable on the serial link must be shielded. At each end of the cable, shield
must be connected to the PE ground. If the connector is used in this end, the connector
housing should be connected to the cable shielding layer. RS485-Modbus must use a pair
of lines and the third line (for common end).
For RS485-Modbus, cable of diameter wide enough must be selected to allow the use
of maximum length (1000m). AWG24 can meet the needs of Modbus data transmission.。
A.9 Definition of Communication Exception Code
When the corresponding error message is detected in the communication process,
the lower machine (i.e., CPU ) will be position “1” of the function code, and feedback
corresponding error code (exception code), to recognize the current error for the host
computer. The corresponding definitions are shown in Table A.6.

Parameter Change Properties（Changeable or Not/Change Condition）
Parameters are changeable in Stop or Running status
Parameters are changeable in Ready status and Inchangeable in
Running status.
Parameters are actual detection value and inchangeable；
（Inverter has
checked the modification attributes of each parameter,which helps
user avoid misoperation）
2、“Parameter decimal” Most of them are decimal（DEC），If the parameter starts with
"0x", it is represented as Hexadecimal.（Such as 0x0000），When editting parameters , the
range of partial bits can be Hexadecimal.（0～F）。
3、“Default Value” It is represented when resetting parameters to factory default, the
value of the parameter is refreshed; but the actual detection value or record value will not
be refreshed.
4、For better protecting parameters setting, inverter provides password protection
function.See 4.3 Keypad Password Setting.
