This example diagram shows the use of the origin adjustment function of the
OMRON R88D-EP/SR Servomotor Driver. The driver completed input (INP)
is used as the origin search completed signal as well as the driver completed
signal. Using this servomotor driver, it is possible to determine the origin
quite accurately. Be sure to set the servomotor driver such that the driver
completed signal is OFF during motor operation and ON while it is stopped.
