CMC-HX soft starter A new intelligent asynchronous motor starting and protection device. It is a motor terminal control device that integrates starting, display, protection and data acquisition. Users can implement more complex control functions with fewer components. The Chinese and English interface display makes the operation easier. At the same time, the CMC-HX soft starter integrates a current transformer, so users do not need to externally match.
First, the role
Reduce the starting current of the motor, reduce the distribution capacity, avoid the investment of capacity increase; reduce the starting stress and prolong the service life of the motor and related equipment; smooth start and soft stop avoid the surge problem and water hammer effect of the traditional starting equipment; A variety of starting modes and a wide range of current, voltage and other settings, can adapt to a variety of load conditions; improve the reliable protection function, more effectively protect the safety of the motor and related equipment;
Second, the characteristics
☆ Unique SCR trigger
Closed-loop control algorithm The unique SCR closed-loop control function is specially designed for standard and heavy loads. The user can select the current limit start and the voltage ramp start according to the load condition to achieve an absolutely smooth torque-free oscillation start effect.
☆Unique load application
The built-in ten load types of the parameters are user-selectable, providing a unique start-up control curve for each type of load, maximizing the soft start to match the load for optimal start and stop.
☆Multiple starting and parking methods
Voltage exponential curve, voltage linear curve, current exponential curve, current linear curve, and programmable kick start torque and starting current limit can be applied in each mode. According to different loads, the corresponding starting curve can be selected to achieve the best starting effect. A variety of parking modes, programmable soft parking, free parking, brakes, pump stop. The unique basic algorithm makes the motor start and stop more accurate and smooth.
☆ advanced communication function
Standard Modbus RTU communication. Optional Ethernet/GPRS communication module facilitates user network connection control and improves system automation and reliability.
☆ analog signal control
The user can input 4-20mA or 0-20mA standard signal, and can set the upper and lower limits of the analog quantity to realize the start and stop control and alarm of the motor. Data (pressure, temperature, flow, etc.) can also be transmitted via a soft starter. With 4-20mA or 0-20mA standard analog signal output function.
☆All refractory materials
Below 90KW is a fully molded shell structure, which is made of flame-retardant ABS material. The upper cover of 90KW and above is made of plastic shell structure, and the main frame is made of aluminum-zinc plate material. It has heat-resisting and anti-corrosion properties.
☆External panel
The panel can be externally led to the operating surface of the device through the fuselage interface for remote operation.
☆ strong anti-interference
All external control signals are optically isolated and have different levels of noise immunity for use in special industrial environments.
☆ double parameter function
With two sets of basic parameters, you can control two motors of different powers separately. ☆ Power frequency adaptive power frequency 50/60Hz adaptive function, convenient for users.
☆ dynamic fault memory
Up to 10 faults can be recorded. It is easy to find the cause of the malfunction.
☆ perfect protection function
The whole process detects current and load parameters, and has microcomputer protection functions such as overcurrent, overload, underload, overheat, phase failure, short circuit, three-phase current imbalance, phase sequence detection, and frequency error.
☆ friendly man-machine interface
It adopts LCD liquid crystal display panel and has two display interfaces in Chinese and English, which makes programming and parameter adjustment more convenient.
