separate CW and CCW pulses are output. When nondirectional pulses are
output, the direction signal determines the direction of positioning. Set this

This pin selects the direction in which the origin is searched for and the direc-
tion from which the origin is reached. If the present position of the positioning
system is near the origin, the origin is searched for in the direction opposite
to that set by this pin.
This pin enables or disables the origin proximity signal. When the pin is set to
ON, ORIGIN SEARCH is executed using the origin and origin proximity sig-
nals. (Note that the origin proximity signal is necessary in modes 1, 2, and 3.)
