Hello,
I would like to use VFD for my bandsaw, but I am quite confused about wiring in the vfd manual and I did not found any answers online.
Here is the wiring diagram from manual:
Can anyone please answer me some questions?
1) Grounding
I dont understand how to ground the motor. 3 phase input with ground cable connects to the vfd, but how to ground the motor? Does the motor needs separete grounding?
Or can I just wire the motor to U, V, W and the groud cable to the same place as the input ground cable?
Here is a simple diagram showing what I mean:
2) VFD cables
I would also like to use VFD cables, just because they are meant for vfd and because of EMI. I am just not sure, were to use them. Between the motor and the VFD or also between power input and VFD?
I would be very grateful if someone can help me answer these questions.
Michal
