4.2.2
Length of the motor cable
Always dimension the motor cable so that the ohmic losses are less than 5 % of the
converter power rating.
The permissible length of the motor cable also depends on the quality of the motor cable and
the converter 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.
Technical data (Page 53)
If you set other pulse frequencies, then you must ensure that the EMC category is complied
with on the plant or system side.
EMC-compliant wiring is required in order that the converter complies with the EMC category
listed in the following table.
EMC-compliant installation of a machine or system (Page 19)
Carefully observe the following section for operation in the first environment:
Electromagnetic compatibility of variable-speed drives (Page 72)
