Motion Control in a Nutshell


A motion control system is very similar to a sound system.

The main components of a sound system are;

1) Loud Speaker
2) Power Amplifier
3) Source of Information
4) Power Supply

Besides the above components, the following elements may be incorporated in the system;

1) Limit or End of Travel Switches

These switches stop the motion in the case they are hit. This feature is to protect the mechanical system against a malfunction.

2) Home Switch

Some systems need to search for a reference point during the power-up. A home switch serves this purpose.

3) Discrete, TTL / CMOS Signals

Some applications may require to interface with other switches, transducers, sensors and devices with TTL / CMOS outputs.

4) Analog Signals

Some applications may require to interface with other transducers, sensors and devices with analog outputs.

5) Quadrature Signals

Some applications may require to interface with other transducers, sensors and devices with quadrature outputs.
