In this example, a servomotor driver is employed and the Z-phase of the encoder
is connected to the origin line driver input terminal and used as the origin signal.
(X axis only for the NC113.)
Note Do not connect anything to the origin signal (10 (X) /32 (Y)). In this example an
OMRON Servomotor Driver is used.

When only one axis is used, short-circuit the CW limit input and CCW limit input
of unused axis to 0 V in 12 to 24 VDC. If these are not short-circuited, the ER-
ROR LED will light, but the axis in use will operate normally.
