(2) Assignment for each axis
Input and output signal for each signal consists of one byte respectively for input and output bit register
(RX, RY) and one word for input and output word register (RWr, RWw).
Control signal and status signal are ON/OFF signals in bit units.
Position data designation and present position data are integers with a sign of one word (16 bits), and the
PLC can handle numeric values of –32,768 to +32,767 (unit=1/100mm), however, set the position data in
a range (0 to effective stroke length) of soft stroke for its actuator.
