6.2.3.2. Pulse Train Resolution
l The parameter CR (RS-232C communication) sets the resolution of pulse train command.
l In addition to the angle magnification with the parameter PC, another angle magnification may
be selected with the parameter CR for øA/øB input.
l Refer to Table 6-10 for the concrete example of resolution.
