Example 3:
b[1:0] = 01= 10, 11 @ Combined unit: unit for position: um; unit for speed: pulse/sec (PPS)
Assume: D1818 (D1898/D1978) = 2,000 (Pulse/REV), D1820 (D1900/D1980) = 100 (um/REV), target position
P(I): 10,000 (um), and operation speed V(I): 10K (PPS). Solve the number of pulses required by pulse
instruction of the positioning controller.

b2 and b3 of D1816 (D1896, D1976, D2056): setting of multiplication of position data
The position data, i.e. zero point position (HP), target position (I) (P(I)), target position (II) (P(II)), current position
(CP), have to be multiplied by the multiplication values listed in the table below.
