4.3.3 Commissioning examples
All SK 1x0E models can be operated as delivered. Standard motor data for a 4-pole standard
asynchronous motor of the same power is parameterised. The PTC input must be bypassed, if a
motor with PTC is not available. Parameter (P428) must be changed if an automatic startup with
"Mains On" is required.
Minimal configuration
The frequency inverter provides all the necessary control voltages (24 VDC / 10 VDC).

Minimal configuration with options
In order to implement completely autonomous operation (independent of control cables etc.) a switch
and a potentiometer such as potentiometer adapter SK CU4-POT is required. In this way, the speed
and direction control in accordance with requirements can be achieved with only a single mains cable
(single phase or three-phase depending on version) (
