Connection of analog signals
Analog signals are connected via the 2 x 4-pole terminal block X6.
Depending on the use of the analog input, the jumper of X3 must be set accordingly.

The maximum permitted voltage difference between an external voltage
source and theGND1 (terminal X6/7) of the controller is 10V (common mode).

The maximum permitted voltage difference between GND1 (terminal X6/7)
and the PE of the controller is 50V.

Configuration of the internal voltage supply:
l
Set a freely assignable analog output (AOUTx) to HIGH level.
l
E. g. terminal X6/63: Assign FIXED100% to C0436 (
&
7-10 ),
10V are thus applied across terminal X6/63.
Note!
Use one of the predefined configurations in C0005 for this application. With
C0005 = XX1X (e. g. 1010 for speed control with control via terminals) FIXED
100% is automatically assigned to the output X6/63 (corresponds to 10 V at the
output X6/63).
