●In-position Signal (INP Signal)
A signal sent when positioning is completed. This signal is to be put out in a allowable range set up against a targeted position.
●Incremental Encoder
An encoder capable of detecting the relative position. Implementation of the return to origin action is needed whenever it is powered on, as this type of encoder can detect only relative positions.
●Incremental Position
A position from any point settled. The antonym is “absolute position.”
●Inertia
A property of matter by which it continues in its existing state (against an inertial system) unless that state is changed by an external force.
