In today's world of industry, where technological developments to support the production process for accuracy, speed and quality as expected and meet the market standard, the technology of production machines nearly all been equipped with the system control / drive in either electronic instrument panel and the drive such as touch screen panel for monitoring panels, Inverters, DC drives, Servo drives and PLC Programmable Logic Controller.
Mostly in automation industries use programmable logic controllers (PLCs). In the industrial automation systems that support it include:
1. Inverter / AC Drive, it is a device used to control a motor cycle production machines.
2. Dc Drive, it consists of an SCR (Silicon Controlled Rectifier) bridge, which converts the incoming three-phase or single AC volts to DC volts. During this conversion process the DC drives can then regulate speed, torque, voltage and current conditions of the DC motor.
3. Servo Drive, it can be used in CNC machining, factory automation, and robotics, among other uses. Their main advantages of DC or AC motors are the addition of the motor feedback. This feedback can be used to detect unwanted motion, or to ensure the accuracy of the commanded motion.
