2.3.2 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 (motor 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.
