2.8 Output choke SK CO1
To reduce interference signals from the
motor cable or to compensate for cable
capacitance in long motor cables, an
additional output choke can be installed
into the inverter output.
During installation take care that the pulse
frequency of the frequency inverter is set
to 3 - 6 kHz (P504 = 3 - 6).
These chokes are specified for a
maximum supply voltage of 480 V at
0 - 100 Hz.
An output choke should be fitted for cable lengths over 100 m/30 m (unshielded/shielded). All chokes
have a protection class corresponding to
IP00. The choke used must therefore be installed in a control
cabinet.
