Digital Display Control Systems are ideal for applications that require live positioning. A feedback device provides a signal to either a panel meter or human machine interface (HMI). The panel meter or HMI then displays live positioning of each device. They provide accurate feedback for various input types and are most often used in conjunction with jog controls.

Features and Benefits

  • Provide Live Feedback
    Digital displays allow users to see the actuator's position, speed, and other relevant data in real-time, enabling informed decisions and adjustments.
  • Shows Up to Four Three-Decimal Positions on Display
    Displays with multiple decimal places allow for a higher level of positional information, enabling fine-tuning of actuator movements for applications requiring precise positioning.
  • Accurate Positioning of Motors
    Enhanced functionality, digital systems enable complex control algorithms, allowing for adjustments to speed, force, and synchronization.
  • Easy to View Process
    Digital display control systems are beneficial for viewing the process of linear actuators due to their enhanced precision, ease of use, and performance optimization.

Options

OPTIONS:

Digital Display Control Methods

Method 1 - Digital Display Controls Using and HMI

Synch-Motor-Starters.jpg

 
  • As the motor turns the actuator the feedback device output changes.
  • The controller reads the output from the feedback devices and displays the actuator position on the HMI
  • HMIs can display positions of multiple devices on one screen.
 
  • Controllers can accept 4 – 20 mA, 0 – 10 VDC, and pulse type inputs.
  • Common feedback devices are linear sensors, potentiometers, and incremental encoders

Method 2 - Digital Display Controls Using A Panel Meter

  • As the motor turns the actuator the feedback device output changes.
  • The panel meter reads the output from the feedback device and displays the position of the actuator
  • Panel meters can accept 4 – 20 mA, 0 – 10 VDC, and pulse type inputs.
 
  • Panel meters come in AC or DC powered models.
  • Each feedback device requires its own panel meter
