1)
On the Technology Units of the SK 2xxE and on the basic I/O of the SK 300E and the basic I/O and standard I/O of the SK 700 / SK 750E, the analog inputs are
implemented as differential inputs. In order to ensure the correct functioning of the potentiometer, the analog input "AIN-" must be connected with the analog ground.
2)
For devices with an AS interface (SK 220E and SK 230E) Analog Inputs 2 (Terminal 16), and instead of AGND (Terminal 12), Terminal 14 (GND) must be used.
In addition, the function of Analog Input 2 (P400[-02]) must be parameterised to the setting {01} = "Setpoint frequency".
3)
Connection of SK POT1-1 to an SK 2x5E can alternatively by made to an IO extension module (SK xU4-IOE) via a suitable mains unit (SK xU4-24V-
…). The
connection is made according to the following pattern.
