Analog input configuration
ƒ Use C0034 to set whether the input is to be used for a master voltage (
±10 V) or a
master current (+4 ... 20 mA or ±20 mA).
ƒ Set jumper bar X3 according to the setting in C0034:
(
Stop!
Do not plug the jumper on the pins 3−4! The axis module cannot be initialised
like this.

Use as master current input
ƒ Master current < 2 mA:
– Variable AIN1_bError_b = TRUE
– An error handling can be set via C0598.
ƒ Master current >= 2 mA:
– Variable AIN1_bError_b = FALSE
