Minimal configuration with options
In order to implement completely autonomous operation (i.e. independent of control cables etc.) a
potentiometer unit (SK CU4-POT) is required. In combination with an integrated mains unit
(SK CU4-
…-24V) a solution can be implemented with an SK 2x5E which uses only one mains cable
(1~ / 3~ according to the version), and a suitable speed and direction control can be ensured (See
connection example below).

NOTE
An 8-Bit A/D converter is integrated into mains units SK TU4- …-24V and SK CU4-…-24V. This
makes it possible to connect a potentiometer or other analog setpoint source to the mains unit
and to transfer this to the digital input of the frequency inverter via a corresponding pulse signal.
