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