Grounding the motor cable shield at the motor end
Always ground the motor cable shield at the motor end. For minimum radio frequency
interference, ground the motor cable shield 360 degrees at the lead-through of the
motor terminal box, or
ground the flattened twisted shield (width > 1/5 · length).
DC connection
The UDC+ and UDC- terminals are intended for common DC configurations of a
number of drives, allowing regenerative energy from one drive to be utilized by the
other drives in motoring mode. Contact your local ABB representative for further
instructions.
