8 Technical data
8.1 General data for frequency inverter series SK 1x0E
Function Specification
Output frequency 0.0 … 400.0 Hz
Pulse frequency 3.0 … 16.0 kHz, standard setting = 6 kHz
Power reduction > 8 kHz for 115/230V device, >6 kHz for 400 V device.
Typical overload capacity 150% for 60 s, 200% for 3.5 s
Protection measures against Overtemperature of the frequency inverter,
overvoltage and undervoltage Short-circuit, earthing fault,
overload, idling
Regulation and control Sensorless current vector control (ISD), linear V/f characteristic curve,

The current which is drawn from the digital outputs must also be covered by this. Any control modules which are
connected to the RJ12 socket also place a load on the 24V supply. (150mA = I
