10.2.3.4 Analog Inputs and Outputs
The expansion card "PosI/O-Monitor" adds analog inputs and outputs to the servo ampli-
fier were pre-programmed signals can be assigned to. A listing of these pre-programmed
functions can be found on the screen page "Analog I/O" of the setup software.
10.2.3.4.1 Analog Outputs ANALOG-OUT 1 and 2
You can use terminals X3C/17 (Analog-Out 1) respectively X3C/19 (Analog-Out 2) to
deliver analog values converted from internal digital values (e.g. tachometer voltage).

10.2.3.4.2 Analog Inputs ANALOG-IN 3 and 4
You can use terminals X3C/21-22 (Analog-In 3) respectively terminal X3C/24-25 (Ana-
log-In 4) with several pre-programmed functions.
