Machine Controls

Description

Machine controls are devices used to automatically control the operation of industrial machinery. The machine controllers work on the basis of two principles: programmable logical control and numerical or computer numerical control techniques. The controller instructs the machine to start or continue an operation by reading the signals from an output device. The machine controllers make use of advanced technology to perform input and output sequencing, machine sequencing, and control solutions for a variety of industrial applications.

Types

Different types of machine controllers are listed below:

• Card type machine controllers
• Stand alone machine controllers
• DIN rail mounted machine controllers
• Embedded machine controllers
• Handheld or portable machine controllers
• Panel mounted machine controllers
• Rack mounted machine controllers

Features

Machine controllers have the following features:

• Vibration resistant
• Integral software
• Global positioning system (GPS)
• Multi-speed control
• Optically isolated to protect the signals
• PID control
• Encoder feedback for digital positioning
• Can be used as a data logger or recorder

Specifications

Specifications for machine controllers include

• AC or DC supply voltage
• Input frequency
• Drive power
• Memory
• Number of axes

Advantages

Machine controllers offer the following benefits:

• Increase productivity by mechanized movement
• Improves the quality
• Highly efficient
• Minimize commissioning time
• Easy and safe to operate

Applications

Machine controllers find their application in automotive, medical, aerospace, marine, military and other industrial areas. Machine control systems are used in construction applications to manage and control heavy equipment. They are also used in earth moving machinery such as bulldozers, excavators, pavers, farm equipment, skiffs, and motor graders.
