(5) Manual pulse generator smoothing magnification setting registers
(D752 to D754) .................................................... Command device
(a) These registers set the smoothing time constants of manual pulse
generators.

(b) When the smoothing magnification is set, the smoothing time constant is as
indicated by the following expression.
Smoothing time constant (t) = (smoothing magnification + 1)
