This document describes a project to automate a stenter machine using a PLC and HMI for speed control. A VFD controls the speed of the master motor, which then synchronizes the speed of the slave motor. The system uses a Delta PLC and HMI for automatic control. Programming is done using WPL software for the PLC and screen editor for the HMI. Potential applications include plastic industry, product counting, drying machines, and more. The goal is to demonstrate speed synchronization between a master and slave motor for a stenter machine model.

3. ABSTRACT
In this project assembly of stenter machine is operated
automatically using PLC and HMI .The speed is
control by vfd.
Principle : speed synchronization
There is one master motor and no of slave motors are
synchronized throgh the command of master motor.
As we are preparing a demo model of the system which
operate stenter machine so only one slave motor is
used.

4.  Introduction to stenter machine

5.  Benefits of PLC for stenter machine
1. Reduce human effort
2. Quick and easy operation
3. Easy to control
 PLC implementation
 PLC converts speed in rpm into analog count and
according to that speed synchronization is achieved.
