Product overview
Three-phase AC asynchronous motor has been widely used in all walks of life, and it is particularly important to ensure the safe control and reliable operation of the motor. The traditional motor control scheme has complex wiring, design, debugging and maintenance workload; the traditional motor protection scheme (thermal relay) has single protection function, poor accuracy and low reliability, and high power consumption.
ST500F/M/H series intelligent motor controller (hereinafter referred to as the controller) is suitable for motor applications with rated frequency 50Hz, rated voltage up to 690V and rated current up to 820A. It combines microcomputer technology, control technology, communication technology and display technology, integrates a variety of motor protection and control schemes, improves the protection function and simplifies the control scheme. It uses the rapid processing ability of the microprocessor to correctly judge and quickly process the abnormal operation state of the motor according to the preset parameters to ensure the safe and stable operation of the production control system. It can also send out alarm signals in time through the Chinese LCD display interface, light indication, relay signal output and communication and other forms.
The application of the controller greatly improves the design and production efficiency, and reduces the workload of on-site debugging and maintenance. In addition, as a communicable intelligent terminal, he also supports a variety of standard fieldbus communication interfaces to achieve networking solutions, realizing decentralized protection control and centralized monitoring and management of motor equipment, and improving the reliability of system operation.
The product adopts modular design (including body, special current transformer and display module). The product is small in size, compact in structure and easy to install. It can be directly installed and used in 1/4 modulus and above various drawers.

Product Features
　　

  • auxiliary working power supply supports AC/DC power supply (AC220V, DC220V/110V).
  • switching input (DI) supports dry node or wet node input (optional AC or DC external power supply).
  • switch output (DO) supports AC or DC loads, and the "control" and "protection" outputs are independent. Signal relay output is used for device self-test or fault alarm output.
  • measurement function is divided into basic current parameter measurement and additional parameter (voltage, residual current) measurement.
  • supports a variety of motor control logic (direct start, variable frequency start, soft start, star delta start, two-way start, etc.).
  • protection function is divided into basic protection (overload, blockage, locked rotor, etc.) and optional protection (residual current, voltage, underpower, tE time, etc.).
  • The on/off and protection parameters of the protection function shall be set on site by professionals as required, and no loss shall be caused when power is lost.
  • "tE time protection" conforms to national standards (GB3836.3-2000) and is suitable for increased safety explosion-proof motors.
  • the action function of the super-large short-circuit current blocking contactor, and issue the command to trip the molded case circuit breaker.
  • "anti-shake" function to ensure that the motor in the grid "jitter", can ensure uninterrupted production operation.
  • "restart function" function ensures that the motor can be automatically restarted in batches when the power grid is lost for a short time.
  • 4 ~ 20mA analog output can select one of the corresponding motor operating parameters to achieve data upload.
  • controller supports standard fieldbus interfaces such as single/dual Modbus-RTU, single/dual Profibus-DP, and DeviceNet.
  • has management functions such as motor current running/stopping time, cumulative running/stopping time, cumulative number of failures, and operation number record.
  • can query the input/output status of the switching value and the current running status of the motor in real time.
  • has the function of recording eight fault parameters (fault type, data and time) of motor equipment, which is convenient for fault analysis.
  • support Chinese/English LCD display operation interface.
