An MPG is similar to an encoder in that it is a type of pulse generator that can be used to communicate a speed and direction to the Commander core. The difference between the two is that an MPG commands motion, while an encoder reports the motion.

The MPG input can be used for a number of functions such as:

  1. A manual pulse generator, which allows for fine adjustment of an axis.
  2. Cam follower, which will allow the axis to follow a cam axis based on its encoder output.
  3. Electronic gearing, which allows an axis to follow the input commands but at a different rate of speed (faster or slower).
  4. Encoder Frequency and Impulse Multiplier/Divider

More information on MPG operation can be found in Section 2.5.2 Manual pulse generator (MPG) operation.
