Standard Synchronization Control Methods

Method 1 - Synchronization Using Motor Starters

  • Encoder 1 and 2 communicate the position of both jack 1 and jack 2 to the controller.
  • The controller turns motor starter 1 and 2 on or off depending on the position of jack 1 and 2.
  
  • Motor starter 1 and 2 apply power to jack motors 1 and 2 based on encoder feedback to keep the system synchronized.

Method 2 - Synchronization Using Variable Frequency Drives (VFD)

  • Encoder 1 and 2 communication the position of both jack 1 and 2 to the controller.
  • The controller commands VFD 1 and 2 to change output frequency to motor 1 and 2 based on each jacks position.
  

  • VFD 1 and 2 change output frequency to both motor 1 and 2 based on the encoder feedback to keep the system synchronized.

  

Method 3 - Synchronization Using Servo Motors With Absolute Encoders

  • The controller commands servo drive 2 to follow server drive 1.
  • Servo drive 2 adjusts the output power to servo motor 2 in order to keep jack 2 in sync with jack 1.
  
  • Integrated absolute encoders in both servo motors feedback position to the controller.
