With appropriate wiring, the frequency inverter can be
controlled directly using the PotentiometerBox. No
additional internal or external components are required.
The motor can be started, stopped and the direction of rotation changed by means of the buttons. The LEDs
indicate the status of the box buttons.
The required setpoint value of the frequency is adjusted with the potentiometer after it has been enabled
(green button).
The integrated 24V mains unit can supply a control voltage to the SK 200E and any additional modules.
