Motor cable length
Always dimension the motor cable so that the ohmic losses are less than 5 % of the inverter
power rating.
The permissible length of the motor cable also depends on the quality of the motor cable and
the inverter pulse frequency. The values specified below are applicable for high quality
cables, such as CY100 or similar, and for the pulse frequencies set in the factory.
Pulse frequencies (Page 86).
If you set other pulse frequencies, then you must ensure that the EMC category is complied
with on the plant or system side.
