Diyengineer,
Thanks for the info,
that changed my mind and at the end i bought a 0.8kw chinese water spindle.
I couldn't find Hitachi in EU for a good price and the shipping from USA was too much, and customs..., so i went with a Toshiba VFNC3.
I was reading other post of yours and wonder what went wrong when you programmed your first spindle and burnt it?
I still have some unanswered questions like:
-How the hell 0.8kw spindle can draw 6AMPs, its not possible, what is the real rating of this spindle as i need it to program the thermal protection in the VFD?
-my VFD has four input options for control:
0: Voltage signal input (0 - 10 V)
1: Current signal input (4 - 20 mA)
2: Logic input
3: Voltage signal input (0 - 5 V)
So i was thinking is it not possible to control it directly from MAch3 by option Logic Input as i read now the
manual and in section 6.5.2 it seems that this VFD can be commanded by frequency pulse input signals which if i am not wrong is PWM and Mach3 outputs this
