3.5 In-position Signal INP
The in-position signals INP from the servo motor driver indicates
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 dia-
gram.
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.
