The VFD itself doesn't cause interference until the spindle is running so would it need a ferrite on the spindle CY cable? Also I have already got all shielding running to a central bank of earth terminals on the sun rail but I thought we were only supposed to connect one end...are we meant to earth both ends?[emoji848]

Ask 10 people and you'll get 12 different replies.
I work in an industry where EM emissions and susceptibility are treated very seriously, and at relatively high power levels. Power systems (emissives) are typically, within these systems, shielded both ends.
You'll find that as the VFD is placed under load it will present some of the heavier switching currents onto it's supply lines. Hence the ferrites. But, horses for courses.
...but there's not enough popcorn in the world to cater for the ensuring arguments.
i have the same setup anychance you have pictures of the actual connections
on the vfd and the axbb-e because it is driving me nuts
cheers
finally got it going no relay needed
removed jumper then
A01 = VI
ACM = 5V0
DCM = 24V0
FOR = pin 7 port 1
REV = pin 8 port 1
pid001 on vfd = 1
pid002 on vfd = 1
