Virtual Axis (Local Mode)

The DMC-3425 controller has an internal motion profiler, also referred to as a virtual axis. This axis is designated as the N axis and has no encoder input and no DAC output. With the N axis, a commanded position profile can be generated using the following modes of motion:
