Another question is for Machine Safety. I included a Killswitch which cuts the 230V input power completely. Now I read somewhere that its better to kill just the wires to the spindle, so that the capacitors cannot uncharge via the spindle and making the spindle down time longer? Is that true?
Do you all use RCD Type B for your CNC with VFD?
What ever you do. Do not put any switch between the spindle and the vfd as that would kill the vfd.
