Use the origin proximity signal to ensure sufficient deceleration time when the
origin proximity reverse is needed. In this example, DIP switch pins 3 and 8
are ON. For DIP switch settings, refer to

Deceleration begins when the origin proximity signal
turns ON.
The origin is sought after the origin proximity signal
turns OFF.

After positioning has been stopped, a deviation counter reset signal of about
30 ms is output.
In this mode, if deceleration has not ended when the origin proximity signal
has turned OFF, positioning is stopped by the origin signal input after decel-
eration has ended. If the deceleration period is short for some reason (such
as starting inside the origin proximity area), the Position Control Unit will de-
