Manual Pulse Generator
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).
The Commander core has a dedicated MPG input for each axis. To enable the MPG input, set the MPE[axis] command to 1. To disable the MPG input, set the MPE[axis] command to 0.
The MPG inputs are controlled by three commands: MPG signal input mode (POL[axis]), multiplication (MPM[axis]) and division (MPD[axis]). These work together to set how the pulses from the MPG input controls the motion of an axis.
MP[axis] can be written to set an MPG position or read to see the current position. The counter value here is the final counts after the electronic gearing stage.
