The data in the table specifies the typical cable length in the sense of the distance between
the motor and the converter when parameterizing the standard clock cycle frequency. Larger
distances are also possible for individual types. Contact the factory for precise values if you
are in the limit range or if there is a long distance between the motor and converter.
Damage to the converter output filter
If you lay too many wires in parallel for the motor cable, the capacitive current in the motor
cable can increase unacceptably and destroy the converter output filter. In the case of
operation with several motors or parallel wiring of motor cables, the maximum possible
distance between converter and motor is reduced. Cabinet units are suitable for wiring in
parallel. Contact the factory for the precise values. Reduce the number of parallel wires to
permissible values.
