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.
