Motor cable length
The tables below show the maximum motor cable lengths for
400 V drives with different switching frequencies. Examples for
using the table are also given.
Under heading “Operational limits”, the “Basic unit” columns
define the cable lengths with which the basic drive unit works
without problems within the drive specification, without installing
