Minimum configuration with options
One switch and one potentiometer (such as SK CU4-POT) are required in order to implement
completely autonomous operation (independent of control lines, etc.). In combination with an
integrated power supply unit (SK CU4-…-24V), a solution that only has the power supply line can be
set up with an SK 2x5E, and demand-oriented speed and rotation direction control can be ensured
(
Section 3.2.4 "Potentiometer adapter, SK CU4-POT").
Information
Convert analog signal
An 8-bit A/D - converter is integrated in the SK TU4-…-24V and SK CU4-…-24V power supply units. This makes
it possible to connect a potentiometer or another analog setpoint source to the power supply unit. The power
supply unit can convert the analog setpoint into an appropriate pulse signal. This signal can be connected to a
digital input of the variable frequency drive and processed by it as a setpoint.
