3.2.4 Potentiometer adapter, SK CU4-POT
Digital signals R and L can be directly applied to the corresponding digital inputs 1 and 2 of the
frequency inverter.
The potentiometer (010 V) can be evaluated via an analogue input of the frequency inverter (if
present) or via an I/O extension. An optional 24V module (SK xU4-24V-...) also provides the possibility
of converting analogue setpoint values into proportional pulses (frequencies). These pulses can in turn
be evaluated via one of the digital inputs 2 or 3 (P420 [02]/[03] = 26/27) of the frequency inverter in the
form of a setpoint (P400 [-06]/[-07]).
