SCR trigger closed-loop control algorithm
SCR closed-loop control function, designed for standard and heavy loads. The user can select current-limiting start and voltage ramp start according to the load condition to achieve smooth torque-free oscillating start effect.
Advanced Unique load application parameters
There are ten built-in load types in parameters for users to choose, and a starting control curve is provided for each type of load, so that the soft start can be matched with the load to achieve a good start and stop effect.
Multiple starting and stopping methods
Voltage exponential curve, voltage linear curve, current exponential curve, current linear curve, and programmable kick starting torque and starting current limit can be applied in each mode. According to different loads, the corresponding starting curve can be selected to achieve a good starting effect. A variety of stopping methods, programmable soft stopping, free stopping, braking, pump stop. The basic algorithm makes the motor start and stop more accurate and smooth.
Advanced Communication function
Modbus RTU communication is standard. Optional Ethernet/GPRS communication module is convenient for users to connect and control the network, and improve the automation level and reliability of the system.
Analog signal control
The user can input 4-20mA or 0-20mA standard signal, and can set the upper and lower limit 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 the soft starter. With 4-20mA or 0-20mA standard analog signal output function.
Fireproof material
Below 90KW is a full plastic shell structure, which is made of flame-retardant ABS material. The upper cover of the power section of 90KW and above is a plastic shell structure, and the main frame is made of aluminum-zinc plate material, which has heat resistance and corrosion resistance.
Movable panel
The panel can be moved to equipment operating surface through machine interface for remote control,which is convenient for on-site use.
Powerful anti-interference property
All external control signals are optoelectronic isolated, and different anti-noise levels are set to adapt to use in industrial environments.
Double parameter function
It has two sets of basic parameters, which can control two motors with different powers respectively.
Self-adaption of power frequency
Adaptive power frequency 50/60Hz adaptive function, user-friendly.
Dynamic fault memory
10 faults can be recorded. It is easy to find the cause of the failure.
Perfect protection function
The whole process detects current and load parameters, and has microcomputer protection functions such as overcurrent, overload, underload, overheating, phase failure, short circuit, three-phase current imbalance, phase sequence detection, and frequency error.
Friendly man-machine interface
It adopts LCD display panel, with two display interfaces in Chinese and English, which makes programming and parameter adjustment more convenient.
