Wiring Diagram check

[eurikain]

Last update of the diagrams:


Note: this is a basic wiring diagram.

Potential changes / improvements:

1. Some people don't cut power directly from the VFD, they use a the start/stop pin of the VFD control interface and control it with a relay. This is safer for the spindle, it allows the VFD to slow down the spindle gradually without hurting it. if you really want to cut completely power from the VFD, some people (JAZZ apparently) also use a timer relay that delays for a few seconds the power cut to the VFD I'm not sure how to do it, I will look at it some time, and then modify the diagram in consequence.
2. Pull earth cable from the star point to the shield of stepper motors and limit switches.
