3.4.2 Potentiometer Adapter, SK CU4-POT
The digital signals R and L can be directly applied to the corresponding digital inputs 1 and 2 of the
SK 2xxE.
The potentiometer (0-10) can be evaluated via a 24V module or I/O extension and converted to proportional
impulses (frequency). In addition, with the inverter versions SK 2x5E, an optional 24V module
(SK xU4-24V-...) provides the possibility of converting analog setpoint values into proportional pulses
(frequencies). These impulses can then be evaluated via the digital input 2 or 3 (P420 [02]/[03] = 26/27) of
the SK 2xxE in the form of a setpoint value (P400 [-06]/[-07]).
