Safety Information Description

Compared with power frequency running

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.

Constant-torque low-speed 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.

Electronic thermal protection value of motor

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.

Running over 50Hz

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

speed range of motor bearings and mechanical devices must be ensured, please inquiry in advance if having questions.

Lubrication of mechanical devices

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.

Negative torque load

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.

Mechanical resonance point of load

Within the output frequency range, the inverter may encounter the mechanical resonance point of the load, now the skip frequency shold be selected.

Occasion of frequently start and stop

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.

Motor insulation check before connection to inverter

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.

Capacitor or voltage dependent component for improving power factors

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.

Contactor and switching devices installed on the output of the inverter

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.

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∗𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀

，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. 𝑅𝑅𝐵𝐵𝐵𝐵𝐵𝐵𝐵𝐵 = 𝑈𝑈𝐷𝐷

𝐼𝐼𝑀𝑀𝑀𝑀

According to the above description, the selection range of brake resistor is：𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀

< 𝑅𝑅 ≤ 2∗𝑈𝑈𝐷𝐷𝐼𝐼𝑀𝑀𝑀𝑀

（2）Brake Resistor Power Calculation

The power of brake resistor：𝑃𝑃0 = 𝑈𝑈𝐷𝐷2

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 ∗ 𝑈𝑈𝐷𝐷2

𝑅𝑅∗ 𝐸𝐸𝐸𝐸%，

𝜆𝜆 = 1 − |𝑅𝑅−𝑅𝑅𝐵𝐵|𝑅𝑅𝐵𝐵

is brake resistor derating coefficient（Normally select 16）。

- 15 -


R is actual brake resistor resistance，PB is brake resistor power.

3.2.3 Output AC Reactor Descriptions The cable between Inverter and Motor should not be too long.If the cable is too long,the distributed capacitance will be large, the harmonic current will be generated easily.

The output AC reactor should be selected when the motor cable is too long.Please refer to the table below:

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. Inputand 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 -


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.

6.2.7 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.

Figure 6-6-1 Speed Loop PI Parameter Switch

● Speed loop slip compensation coefficient 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.

● Speed Regulator、Torque Regulator Mode Selection

Speed / Torque Mode is switched by parameter F3.00 ，also it can be switched by

setting DI1 ～ DI and HDI terminals（DI function 38）. ● 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 (AI1、AI2 setting) 、 6.2.4 Pulse 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

to rated torque of motor，torque control Decel. Time F3.25 means deceleration time of torque reference from rated torque of motor to 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.

When the overload protection gain FE.01 is set to 100%, the inverse time limit characteristic of motor overload protection is defaulted to: motor overload fault will occur after running continuously for 10 minutes under the condition of 150% motor rated current; motor overload fault will occur after running continuously for 80 minutes under the condition of 110% motor rated current.

● Motor Overload Early Alarm

Motor overload early alarm function is used to output warning signal to control system through DO before motor overload fault protection. The early alarm coefficient is used to determine the level of early alarm before motor overload protection, and the larger the value, the smaller the early alarm amount.

When the cumulative output current of the inverter is greater than the overload time (the cumulative value of the inverse time curve of motor overload protection) × the overload alarm level FE.03 of the motor, the DO will output the effective signal of motor

8.4 Regular Maintenance According to the using environment, the user can conduct a regular inspection for the

inverter every three months or six months.。 General inspection contents: 1．Whether screws of the I/O terminal are loose, tighten with a screwdriver;

- 98 -


2．Whether the power terminals are in poor contact, whether copper bus bar connections are with overheating signs;

3．Whether the power cables, control cables are damaged, especially the casing in contact with the metal surface is with cut marks;

4．Whether the insulation binders for the power cables have fallen off;

5．Comprehensively clean dust on the circuit board and air duct, using a vacuum cleaner is recommended;

6．For inverter insulation testing,all input and output power terminals（R、S、T and U、

V、W）must be connected with short wires then tested to the ground. Testing the insulation of the single terminal to the ground is forbidden. Otherwise, it is dangerous to damage the inverter. Please use 500V megoh meter；

7．When testing motor insulation, the input terminals U, V, W of the motor must be removed from the inverter and tested motor separately. Otherwise, the inverter will be damaged.

Attention

1. The voltage withstand test has been finished before leaving the factory; the users no longer have to conduct the test again, otherwise the improper test could damage the device. 2. Replacing the original components in the inverter with those different models and electrical parameters may result in damage to the inverter.

8.5 Spare Parts Replacement Wearing parts of the inverter mainly include cooling fan and bus capacitor ; the life of

them are closely related to operational environment and maintenance. The following table shows the general service life.

Table 8.2 Parts Service Life

Discriminant criteria: Whether there is liquid leakage, whether the safety valve has projected, measurement of the electrostatic capacitance and insulation resistance.

3．Relay

Possible damaged reason: Corrosion, frequent action.。 Discriminant criteria: Opening and closing failure.

8.6 Storage After purchasing the inverter, attention must be paid to the following for temporary and

long-term storag：

1．Avoid storing in the hot, humid environment with much dust, metal powder; ensure good

ventilation；

2．The inverters which have been stored for more than 2 years must been done precharge experiment. When energized, the voltage regulator is used to slowly increase the voltage to the rated value for nearly five hours without load.

Figure A-4-1 Modbus Protocol Format Modbus adopts “Big Endian” encoded mode,and sends the upper byte and then the

lower byte. 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.

The following examples show how to read the parameters of the internal register 0x0101（F1.01）of slave 5 in RTU mode.

In ASCII mode, the frame head is"0x3A", the default frame tail is“0x0D, 0x0A”, and the frame tail can be configured by users. In this mode, besides the frame head and tail, the other data bytes are all sent in ASCII code; upper 4-bit byte is sent first, followed by lower 4-bit byte. Data in ASCII mode is 7-bit bytes long. For “A”~“F”, their ASCII codes in capital are used. At this time, the data adopts LRC check, and the check covers the information from the slave address to data. Checksum is equal to the complement of sum (carry bits are abandoned) of all characters participating in the data check.

The following examples are used to write 4000 (0xFA0) to the internal register 0201 (A2.01) of slave 5 in ASCII mode. Request frame：

Code Description

0x03 Read inverter parameters, including function code parameters, command parameters and status parameters.

0x04 Read inverter parameter attribute value.

0x06 Rewrite single 16-bit bytes inverter function code parameters or command parameters.

0x10 Rewrite multiple inverter function codes or command parameters.。 A.5.2 Address mapping rule for function parameter of inverter

- 103 -


Group number mapping of the inverter function parameter is the upper bytes of Modbus register address (0~F corresponding values are 0x00~0x0F); Group Index (parameter number in the group) mapping is the lower bytes of Modbus register address (00~99 corresponding values are 0x00~0x63). When data is only required to be stored in RAM (i.e.,data not stored on power-down), the highest position of the address is “1”. For example：The corresponding register address of Parameter“F5.27”is“0x051B”：

1）Corresponding address is “0x851B”when data only be stored to RAM.

2 ） Corresponding address is “0x051B”when data only be stored to EEPROM(Data stored on power-down). A.5.3 Obtain the parameter attribute of the inverter function code

Parameter attribute of the inverter function code can be obtained by 0x04 command code. Attribute definition format is shown in Table A.2.。

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.
