In-Position Signal INP

The in-position signal INP from a servo motor driver indicates its
deviation error. If there is no deviation error then the servo’s posi-
tion indicates zero. The signal names, pin numbers, and axis num-
bers are shown in the table below:

The input circuit of the INP signals is shown in the diagram below:

The in-position signal is usually generated by the servomotor
driver and is ordinarily an open collector output signal. An external
circuit must provide at least 8mA current sink capabilities to drive
the INP signal.
