2.5.1 Inputs_ANALOG1 (analog input)
The input is the interface for differential analog signals between terminals X6/1, 2. It can be used as
a setpoint input or as an actual value input.

C0034 can be used to set whether the input is to be used for a master voltage or a master
current:

Please also observe the jumper position X3 at the front of the 9300 Servo PLC in this
connection (see terminal assignment).
Use as a 4 ... 20 mA master current input
·
If the input is used as a master current input (C0034 =1), then AIN1_bError_b = TRUE as long
as the absolute value of the master current is < 2 mA, otherwise it is FALSE.
·
C0598 can be used to set the response for the case that the absolute value of the master
current is < 2 mA:
