Wiring system
The motor cable shall be sleeved into the metal tube.
The input power wire and output motor wire shall be kept away from each other if
possible. The equipment and signal cables vulnerable to interference shall be kept far
away from the drive.
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.
The wiring of TA/TB/TC shall be separated from wiring of other main circuit terminals.
It is forbidden to short circuit the shielding layer and other signal cables or
equipment.
