Quick addition of 2.2kw spindle with VFD - Is this possible?

[Doddy]

Just to note, the Sprint 400 manual claims that all terminals, including pots (for speed control) float at mains voltages. So, in theory - to answer your question - yes, but I would suggest that the output from the Spindle 5 board is used to drive one, and only one of the speed controllers. Best that you have a connector system that requires you to disconnect from one to feed the other to avoid possible inadvertent contact.

Thanks Doddy, I was already considering fitting of a connector system.

Looking at how the system is set up at the moment I am a little bemused. The motor control relays on the Spindle V5 aren't connected so I assume the Sprint board turns the spindle on/off (or the Cable porter spindle is soley controlled with the 0-10v output). Either way am I correct that for the spidle powered by the VFD I don't need the Sprint? If this is the case my easiest (and foolproof) option is the simply add a new Spindle V5 and add a connector so only one can be used at a time. Can you suggest any PWM to Analogue boards to ue instead of the spindle V5?

My setup is wired similar to this except the stop/cc and stop/cc are not used


Spndle V5 board for reference


Thanks
