[PAULRO]

it's time to wire my spindle and inverter so i could do with some guidance. i have read the threads and hope my understanding of what's required is up to scratch. i have the Huanyang HY02D223B VFD and 2.2 KW spindle. i have the VFD wired 220 vac to '' R & T'' on the input side. i have the spindle wired with 4 core 1.5 mm2 with the earth soldered to pin 4. i tried to undo the back cover of the spindle to get an earth to pin 4 on the spindle side of the plug but met with resistance so i read the threads again and realise i will more than likely have to reseal the back flange once disturbed. so i'm thinking,leave well enough alone and maybe i could take a seperate earth from the spindle bracket back to my VFD earth terminal and save myself the hassle of uneccessary resealing.
this then leaves the wiring of the spindle to the inverter. wires 1,2,3, to U,V,W, and earth (as mentioned) .
so my BOB has a PWM input but i want to become more familar with the inverter and the manual input side of things and maybe in a couple of days when i'm up to speed with the VFD then introduce the PWM. this is the slow approach to the set up but i'm waiting on a pump for the spindle so i have the time. so my question is as follows,.. am i better off to power the VFD and set the parameters without the spindle wired in or does it matter?
