Mode 3 makes use of the origin adjustment functions of OMRON Servomotor
Driver R88D-H. The servomotor's positioning completed signal (INP) is used as
the origin search completion signal. Do not use an origin, Z-phase, or error
counter reset signal.
Use the origin proximity signal to ensure sufficient deceleration time when origin
proximity reverse is needed. Bit 01 (proximity signal) and 04 (proximity reverse)
of addresses 2021 (X axis) and 6021 (Y axis) are ON.
ORIGIN SEARCH (Start)
When the servomotor driver receives the origin adjustment command (H.RET)
from the Position Control Unit, the error counter of the servomotor driver is inter-
nally reset by the Z-phase signal (which is output by the encoder) and the servo-
motor driver stops.

The point at which positioning stops is the same as in modes 1 and 2. There are
some differences in operation depending on the starting position for ORIGIN
SEARCH. For details, refer to the examples under Mode 1.
