6.10.5 Voltage drop
Select the cable cross-section of the motor cable so the voltage drop is as small as
possible . An excessively high voltage drop means that the full motor torque is not
achieved.
You can determine the expected voltage drop using the following tables. For shorter
cables, you can calculate the voltage drop by converting in proportion to the length.
