Key signal cables shall adopt shielding cable. It is suggested that the
shielding layer shall be grounded with 360-degree grounding method and
sleeved into the metal tube. The signal cable shall be kept far away from
the drive power input wire and output motor wire. If the signal cable must
cross the power input wire and output motor wire, they shall be laid
orthogonal.
When analog input of voltage or current is adopted for remote frequency
setting, twisted shielding cable shall be used. The shielding layer shall be
connected to the grounding terminal PE of the drive, and the signal cable
shall be no longer than 50m.
