3.6 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 input circuit of the INP signals is shown in
the diagram below:
Figure 3-9: In-position Signal INP
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 6mA current sink capabilities to drive
the INP signal. For more details of INP signal operations, refer to
section 4.7.
