3.6 In-position Signal INP
The in-position signals INP from the servo motor driver indicate the
deviation error is zero, that is the servo position error is zero. The relative
signal name, pin number and axis number are shown in the following table.

The input circuit of the INP signals are shown in the following diagram.
The in-position signals are usually from servomotor drivers, which usually
provide open collector output signals. The external circuit must provide at
least 5 mA current sink capability to drive the INP signal active. For more
details of the INP signal operating, please refer to section 4.2.1.
