I am putting together a 3 axis CNC mill system using the KFlop and KStep. There is a VFD which is used to power the spindle.
The VFD has 5VDC and 24VDC auxiliary outputs in addition to its normal VFD motor output. It would be convenient to use this 5VDC supply to power the KFlop and the 24VDC for the limit switch and input circuits. This way, I would not need to install dedicated 5VDC and 24VDC power supplies.
My question is - will this work acceptably, or do you expect excessive noise on the 5V supply from the VFD such that it might cause problems?
