NSK MEGATORQUE M-ESA-Y3040T25 - Pulse Train Resolution

— 10-13 —
10.2.3.2. Pulse Train Resolution
l Set the resolution of the pulse train with the CR parameter (via RS-232C).
l In the case of øA/øB input, the pulse train resolution is multiplied by the PC parameter value, then
by the CR parameter value.
l Refer to Table 10-7 for the concrete data of resolution.
