Introduction
In the past few years, the number and the size of automated car park are increasing. The controlling system should be designed to handle the large amount of parking car efficiently. A reliable and flexible positioning control system is necessary.

Technology
For the positioning control, AC motor is controlled by frequency drive supported with encoder and proximity sensor. After receiving system information, such as weight of car, position, speed configuration etc., it will automatically set up a suitable positioning control parameter configuration for controlling the speed, direction and applying different controlling setpoints. System will follow the above parameters to control operation of motor. It is flexible for different parking system for positioning control.

 Features

• Wide Weight Range
  The different weight of car affects the accuracy of positioning control. Our system can check and handle the different weight of cars, including individual weight of cars or the total weight of parking system, to maintain accuracy and reliability of positioning control.
  

• Accurate Speed Change
  For the balancing between operation time and accurate positioning control, handling for high/low speed change is important. Our technology can apply the system information and configuration to provide the critical speed changing point. It helps to reduce time for storing or retrieving cars, but not reducing accuracy of operation.
  

• Automatic compensation
  System gets different system information to do compensation of movement. It prevents too fast, over-running or missing target.
  

• Highly Efficiency
  By using frequency drive to control AC motor for positioning control, it reduces the cost comparing to stepping or servo motor. Intelligent weight and speed handling help to reduce traveling time and increase efficiency of parking system.
