From Galil Motion Control

A majority of amplifiers in the market place today take a control signal from a motion controller that is in the form of +-10VDC or a pulse train and direction bit. However there are some amplifiers that expect a control signal that is a pulse width modulated (PWM) signal with a varying duty cycle. All Galil controllers have the ability to provide this type of output as well. The tables below explain how to configure the controller for different types of PWM signals.

CNC Controllers
CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.
Machine Controllers and Monitors
Machine controllers and monitors use electronic numeric control and monitoring interfaces for programming and calibrating computerized machinery.
Motion Controllers
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
