Operating mode / I/O assignment
In this chapter you can read about:
I/O assignment for control via the Compax3 inputs/outputs ............................................134
I/O assignment, control word and status word with control via COM port .......................135
The operating mode defines the I/O assignment of the Compax3 I/Os.
4.1.10.1
I/O assignment for control via the Compax3
inputs/outputs
If control is not made via RS232 / RS485, an M - option (M10 or M12) will be
required. The assignment of the inputs and outputs is fixed.

The display of the digital inputs in the optimization window of the C3 ServoManager
does not correspond to the physical status (24Volt=on, 0Volt=off) but to the logic
status: if the function of an input or output is inverted (e.g. limit switch, negatively
switching), the corresponding display (LED symbol in the optimization window) is
OFF with 24Volts at the input and ON with 0 Volts at the input.
