4.3.4 Commissioning examples
All SK 2xxE devices can basically be operated in the condition in which they are delivered. Standard
motor data of a standard NORD 4-pole asynchronous motor of the same power is parameterized. The
PTC input must be bypassed if no motor PTC is available. Parameter (P428) must be changed if an
automatic startup with "Power On" is required.
