GENTLE PEOPLE , GENTLE PEOPLE
It is ok to "make it work" , it is ok to make it right , it is Always "best practice" to make it right.
As a wise man once said " make it dirty, make it work if you are in concept mode. when it is proven you then do it pretty (right) "
i have tried both methods and they both work. there really isnt a wrong answer.
i am repairing cnc machines now, big 18000 kg beasts using 12ga wire on a 50 foot chord to power and test functionality, is it osha-no
have i accomplished my mission of functionality -yes , will i run parts-no . but i can show the machine to sell and test every function-yes
As for the issue of connecting "SHIELDED WIRING FOR SERVO/MOTOR/DRIVES" ABSOFRIGGENLUTELY you should have a shielded ground all the way back to the drive.
you may not know this but quality drives will LOOK at ground for phase/voltage/ac/dc/rf ...... and the ground should be same size as the power leads.
shielding is only important if you have electronics in a system, OH YEAH i think you cnc has a bit, you should have shielded cables on everything.
just look at "twisted pair" wires cables and such, ugly stuff but why???
if you have an idea or are experimenting , by all means use whatever you have to GET_R_DONE, but stop and then put it together the RIGHT way, with safety and quality for all.
In a busy woodshop, I thought it would be much safer to have the cables exiting the cable track at the rear of the machine so I wouldn't snag anything while carrying boards past it. And imo it just looks cleaner.
Spindle grounding:
I contacted solar.Jean and asked if their pin4 was connected or unused? And number of poles. I got this response:
"New message from: solar.jean
Dear friend,
Thanks for your message!
My friend, the earth is connected from pin 4 to the motor housing. And our motor is 2 pole.
When you use this VFD for this spindle motor 0-400HZ , Please set the parameters of the VFD as our following suggestion step by step, and don't change the sequence:
Step 1: Set PD005 =400
Step 2: Set PD004 =400
Step 3: Set PD003 =400
Step 4: Set PD072 =400
PD144=3000"
