3.1.2 Potentiometer adapter, SK CU4-POT
Part no.: 275 271 207
Digital signals R and L can be directly applied to the corresponding digital inputs 1 and 2 of the
variable frequency drive.
The potentiometer (0 - 10 V) can be evaluated via an analog input of the variable frequency drive (if
present) or via an I/O extension. An optional 24 V module (SK xU4-24V-...) also provides the
possibility of converting analog setpoints to proportional pulses (frequencies). These pulses, in turn,
can be evaluated via one of the digital inputs 2 or 3 (P420 [02]/[03] = 26/27) of the variable frequency
drive in the form of a setpoint (P400 [-06]/[-07]).
