Notes
1. Connect the NYCe 4000, power supplies or other equipment on a metal
frame or mounting base and make sure there is a galvanic contact.
2. EncVref and EncGND are allowed to be used.
Follow these cabling instructions:
●
Always use a shielded cable.
●
The shielding on the NYCe 4000 side of the cable must be connected to
Shield (house connector).
●
If the equipment on the application side is metal, connect the shield to
the equipment housing.
For proper use, this ground may not be connected to motor or
digital I/O ground.
