Remarks
RD75 (CW/CWW mode)
(Note)When (CW/CWW mode) and (PULSE/
SIGN mode) are connected incorrectly, the
motor moves only one direction.
RD75 (PULSE/SIGN mode)
The number of pulses are multiplied by 4 to
count. When differential line driver is used,
the number of pulses after the number
encoder pulses is quadruplicated should be
500k pulses/s or lower. When open collector
is used, the number should be 200k pulses/s
or lower.
