Shielded Cable Connection - INVT Goodrive880 Series Hardware Manual

Goodrive880 Series Water-Cooled Drive Hardware Manual
When laying multiple types of cables, the cables should always be routed along the alignment grooves or
metal pipes in equipotential connection, with different types of cables separated as much as possible. You
can better improve electromagnetic compatibility by using metal spacers to isolate different types of cables
in the same metal groove or metal pipe.

4.3.4 Shielded cable connection

The shield layer of signal cable is grounded at both ends, of which the grounding points must be the same.
That is, if the shield layer at the upper computer side is connected to PE, the shield layer at the drive side is
also connected to PE; if the shield layer at the upper computer side is connected to GND, the shield layer at
the drive side is also connected to GND. It is recommended to connect the both ends of the shield layer to PE,
which is the housing.
The unshielded part of the control cable that is shielded should be as short as possible, and the shield layer
is connected to the nearest PE end. If the cable is stripped too long, the core is susceptible to interference of
signals, especially analog, communication, and encoder signals.
