1: Valid
The over-modulation function means that the inverter increases the output voltage by adjusting the utilization rate of
the bus voltage. When the over-modulation is effective, the output harmonics will increase. If long-term low-voltage and
heavy-load operation or high-frequency (over 50HZ) operating torque is insufficient, this function can be turned on.

Chapter VIII EMC (Electromagnetic Compatibility)
8.1
Definitions
Electromagnetic compatibility (EMC) refers to the ability of electrical equipment to operate in an electromagnetic
interference environment without interfering with the electromagnetic environment and to stably realize its functions.
8.2
Introduction to EMC Standards
According to the requirements of national standard GB/T12668.3, the inverter needs to meet the requirements of
electromagnetic interference and anti-electromagnetic interference.
Our existing products comply with the latest international standard: I e c/e n 61800-3: 2004 (adjustable speed electrical
power drive systems part 3: EMC requirements and specific test methods), which is equivalent to the national standard
GB/T12668.3.
IEC/EN61800-3 mainly investigates inverters from two aspects: electromagnetic interference and anti-electromagnetic
interference. Electromagnetic interference mainly tests radiation interference, conduction interference and harmonic
interference of inverters (this requirement is applicable to inverters used for civil use). Anti-electromagnetic interference
mainly affects the transmission immunity, radiation immunity, surge immunity, fast burst immunity, ESD immunity and
power supply low-frequency end immunity (specific test items include:
1. Immunity test of input voltage sag, interruption and change;
2. Commutation notch immunity test;
3. Harmonic input immunity test;
4. Input frequency change test;
5. Input voltage imbalance test;
6. Input voltage fluctuation test). According to the strict requirements of IEC/EN61800-3, our products are installed and
used according to the instructions shown in 7.3, and will have good electromagnetic compatibility in general industrial
environment.
8.3
EMC guidance
8.3.1 Influence of harmonics:
High-order harmonics of power supply will damage the inverter. Therefore, it is suggested to install AC input reactors
in some places with poor power grid quality.
8.3.2 Electromagnetic interference and installation precautions:
There are two kinds of electromagnetic interference, one is the interference of the electromagnetic noise of the
surrounding environment to the inverter, and the other is the interference of the inverter to the surrounding equipment.
Precautions for installation：
1) the grounding wires of inverters and other electrical products shall be well grounded;
2) The power input and output lines and weak current signal lines (such as control lines) of the inverter should not be
arranged in parallel as far as possible, but should be arranged vertically when there are pieces;
3) It is recommended to use shielded cable or steel pipe to shield the power line for the output power line of the inverter,
and the shielding layer should be reliably grounded. For the lead of the interfered equipment, it is recommended to use
twisted shielded control line and reliably ground the shielding layer;
4) If the length of motor cable exceeds 100m, it is required to install output filter or reactor.
8.3.3 Treatment method of interference of peripheral electromagnetic equipment to
inverter:
Generally, the electromagnetic influence on the inverter is caused by a large number of relays, contactors or
electromagnetic brakes installed near the inverter. When the inverter malfunctions due to interference, the following
measures are recommended:
1) Surge suppressors are installed on devices that generate interference;
2) Install a filter at the input end of the inverter, refer to 7.3.6 for specific operation;
3) The leads of control signal lines and detection lines of inverters shall be shielded cables and the shielding layer shall
be grounded reliably.
8.3.4 Measures to deal with interference caused by inverter to peripheral
equipment:
There are two kinds of noise in this part: one is the radiation interference of inverter, and the other is the conduction
interference of inverter. These two kinds of interference make peripheral electrical equipment suffer electromagnetic or
126
electrostatic induction. Thereby causing misoperation of the equipment. According to several different interference
situations, refer to the following methods to solve them:
1) The instruments, receivers and sensors used for measurement have weak signals. If they are close to the inverter or
in the same control cabinet, they are prone to interference and misoperation. The following solutions are recommended: try
to stay away from interference sources; Do not arrange the signal line and the power line in parallel, especially do not
bundle them together in parallel; Shielding wires shall be used for signal lines and power lines, and the grounding shall be
good; Add ferrite magnetic ring on the output side of the inverter (choose the suppression frequency in the range of 30 ~
1000 MHz) and wind it for 2 ~ 3 turns in the same direction. For the bad situation, you can choose to install EMC output
filter;
2) When the interfered equipment and the inverter use the same power supply, it will cause conducted interference. If
the interference cannot be eliminated by the above methods, an EMC filter should be installed between the inverter and the
power supply (refer to 7.3.6 for selection operation);
3) The peripheral equipment is grounded separately, which can eliminate the interference caused by leakage current
in the grounding line of the inverter.
8.3.5 Leakage current and treatment:
There are two forms of leakage current when using inverter: one is leakage current to ground; The other is the leakage
current between lines.
1) factors affecting the floor drain current and solutions:
There is distributed capacitance between the conductor and the ground, and the greater the distributed capacitance,
the greater the leakage current; Effectively reduce the distance between inverter and motor to reduce distributed
capacitance. The larger the carrier frequency, the greater the leakage current. The carrier frequency can be lowered to
reduce leakage current. However, reducing the carrier frequency will lead to an increase in motor noise. Please note that
installing reactors is also an effective way to solve leakage current.
The leakage current will increase with the increase of loop current, so when the motor power is high, the corresponding
leakage current will be large.
2) Factors causing leakage current between lines and solutions:
There is distributed capacitance between the output wires of the inverter. If the current passing through the wires
contains higher harmonics, it may cause resonance and leakage current. At this time, if the thermal relay is used, it may
cause misoperation.
The solution is to reduce the carrier frequency or install an output reactor. When using the inverter, it is suggested that
no thermal relay should be installed between the inverter and the motor, and the electronic overcurrent protection function
of the inverter should be used.
8.3.6
Precautions for installing EMC input filter at power input end:
1)
Note: Please use the filter strictly according to the rated value; As the filter belongs of Class I electrical
appliances; the metal outer shell for the filter should have good contact with the metal for the installation cabinet of large
area; and it is required of have good conductivity continuity; otherwise; there will be the danger for electrical contact and
seriously affect the EMC effect.
2) Through EMC test, it is found that the filter ground must be connected to the same common ground as the PE end of
the inverter, otherwise the EMC effect will be seriously affected.
3) Install the filter as close as possible to the power input of the inverter.
127
Chapter IX Fault Diagnosis and Countermeasures
9.1
Fault Alarm and Countermeasures
In case of abnormality during operation, the inverter immediately blocks the PWM output and enters the fault protection
state. At the same time, the current fault information is indicated by the flashing fault code on the keyboard. At the same
time, the fault indicator ALM lights up. At this time, it is necessary to check the cause of the fault and the corresponding
treatment method according to the method suggested in this section. If the problem still cannot be solved, please contact
our company directly. Please refer to Table 9-1 Fault Diagnosis and Elimination for corresponding solutions.

Appendix 1: Modbus communication protocol
1. RTU mode and format
When the controller communicates on Modbus bus in RTU mode, every 8-bit byte in the information is divided into 2
4-bit hexadecimal characters, which
The main advantage of mode is that the density of characters transmitted by mode is higher than that of ASCII mode at
the same baud rate, and every message must be continuously transmitted.
(1) the format of each byte in 1)RTU mode
Coding system: 8-bit binary, hexadecimal 0-9, A-F.
Data bit:
1-bit start bit, 8-bit data (lower bit first sent), 1-bit stop bit, and optional parity bit. (Refer to RTU data
frame as sequence diagram)
Error check area: cyclic redundancy check (CRC).

Notes:
1. In the above examples, the address of the inverter is selected as 01 for convenience of explanation. When the inverter is
a slave, the address is set in the range of 1 ~ 247. If any data in the frame format is changed, the check code should be
recalculated. You can download the CRC16-bit check code calculation tool online.
2. The starting address of the monitored items is D000, and each item is offset by the corresponding hexadecimal value
based on this address, and then added to the starting address. For example, the monitoring start item is D-00, and the
corresponding start address is D000H (1D00H). Now read the monitoring item D-18, 18-00 = 18, and if 18 is converted into
hexadecimal for 12H, then the reading address of D-18 is D000h+12h = D012h (1D01H
3. The frame format when the slave response information is abnormal: inverter address+(80H+ function code)+error
code+16-bit CRC check code; If the frame returned by the slave is 01H+83H+04H+40F3H；; 01H is the slave address, 83H
is 80H+03H, indicating read error, 04H indicates illegal data length, and 40F3H is a 16-bit CRC check code.
