Something that rarely gets mentioned...Power required...
I have a 3ph 2.2kW spindle motor on a vfd, 700w X servo, 700w Y servo, 400w Z servo, maybe 100w for pc and controller on this machine.
How do i calculate the supply capacity allowing for diversity - it will not be running 100% flat out all the time :)
I know i need to uprate the MCB's and supply cables as the build was originally for the small 1.5hp spindle motor.
Adding up the maximum ratings for all drives gives a figure way more than i can supply :)Last edited by Davek0974; 05-10-2016 at 09:26 AM.
