(5) Inversion at limit end, zero return operation at low speed, and stop at origin (value of
parameter 1 address A+0003 set to "04")
With this mode, only the origin signal is captured from the external input connector and zero return
is performed. The limit end signal is used instead of the origin proximity signal.
Both open collector and differential driver output origin input signals can be input.
In this mode, operation is started at high-speed zero return as shown below, operation is
immediately inverted by the limit end signal after which operation is continued at low-speed zero
return, and operation is stopped immediately by the initial origin signal to confirm the origin.
(6) Origin proximity signal and origin signal both unused
(value of parameter 1 address A+0003 set to "05")
Neither the origin proximity signal nor origin signals are used. The point where zero return is started
up is taken as the origin. This mode is mainly used for speed control on rotation systems or for initial
testing.

(Note)When inversion operation is performed at the limit end, perform zero return at a speed that
will not apply stress on the mechanical system as inversion is instantaneous.
