1. Abnormal soft start to prevent damage
When the braking resistor is connected incorrectly, or the soft start fails due to the abnormal bus voltage, or the bus is connected to the braking unit failure and short circuit, effective protection can be provided to prevent the inverter from being damaged. After the abnormality is eliminated, it will automatically resume operation.
2. Three-phase SCR rectifier
Change the soft start method of traditional product contactor + resistance to reduce failure points. Fully sealed components enhance the adaptability of the product to high dust environment. It reduces the electromagnetic radiation in space, simplifies the structure layout, reduces the heat generation of the whole machine, and improves the reliability of the whole machine.
3. Independent air duct design
By reserving the independent air duct installation function, the product can be installed in a submerged manner, and the air duct part can be installed through the wall, saving space, and isolating the high-fiber environment from damage to the cooling fan. The flexibility of the product to adapt to the environment is stronger.
4. Speed tracking
The speed tracking restart function realizes smooth start without impact on the rotating motor, and at the same time prevents over-current protection.
5. DC braking
DC braking can achieve smooth, shock-free, fast and accurate braking.
6. Thermal simulation analysis
The thermal simulation analysis of the product can clarify the distribution of the flow field and temperature field, optimize the design of the air duct or cooling system, make the temperature distribution of the whole machine more uniform, and the structure heat dissipation design more accurate, ensuring long-term reliable operation of the product.
7. Strong environmental adaptability
Independent air duct design, optional terminal board according to the protection level, and dust-proof accessories can meet the needs of most places and are easy to clean. It has lightning protection function, strong immunity to power grid fluctuations, and adapts to instantaneous power failure without stopping the power grid. Corrosion resistance adapts to various complex environments.
8. Excellent responsiveness
The vector frequency conversion control technology can achieve quick dynamic response effect, and on the basis of ensuring the stable output speed, the system can quickly follow the load change and improve the operating efficiency of the system.
9. Open loop vector control of permanent magnet synchronous motor
Open-loop vector control permanent magnet synchronous motor is adopted, with simple wiring, high speed control accuracy, and wide product applicability.
10. Excellent anti-overcurrent/anti-overvoltage function
In the extremely short acceleration and deceleration time and load fluctuations, it has superior transient current and voltage control capabilities, no over-current and over-voltage phenomena will occur, and trip-free operation is guaranteed to the greatest extent.
11. Low frequency oscillation
The use of effective suppression algorithms can suppress and solve the problems of stator current oscillation, speed and torque fluctuations in traditional asynchronous motors, and improve the stability of the system.
12. Overmodulation
Compared with the traditional sine modulation, the PWM over-modulation function can improve the utilization rate of the bus voltage and increase the output voltage of the inverter. It is suitable for long-term low grid voltage, or long-term heavy load or impact load occasions.
14. Multiple braking methods
Deceleration DC braking:
It realizes fast, stable and accurate parking, and is suitable for occasions that require stable, impact-free and precise parking, such as knitting, sewing, lifting, hoisting, etc.
Power-on DC braking:
It is suitable for occasions that require the motor to be braked before starting to eliminate irregular rotation caused by external factors, such as large fans.
Energy consumption braking:
0.75~110kW each specification has built-in braking unit. When it needs to stop quickly, it can be directly connected to the braking resistor, which is suitable for the occasions where large inertia load frequently brakes.
Flux brake:
The kinetic energy of the motor is converted into heat energy to be consumed on the motor rotor. This function can effectively suppress the increase of the bus voltage during the braking process.
