2.6 Output choke (accessories)
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.
Take care during installation that the pulse frequency of the
frequency inverter is set to 3-6kHz (P504 = 3-6).
These chokes are specified for a maximum supply voltage of
460V at 0-100 Hz.
An output choke should be fitted for cable lengths over
150m/50m (unshielded/shielded). Further details can be found
in Chapter 2.10.4 "Motor cable".
The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.
