Aluminium Profile Type Router - Initial questions

[CNCRY]

Thanks kitwin , think that makes sense now , will connect one up to UCCnc and test.
Looks like too late for replacement ballscrew from Fred , can any 1610 ballscrew work with the SFU nuts ? Or is the fit not right unless factory paired ?
E.g if I get a gten machined one will it work with SFU ballnut from Fred...

Replacement ball screw ordered now, so will report back if SFU nut fits well.
I tested the limit switches and all working as they should - they even light up:) Thanks Kitwin !
The final piece of the wiring puzzle (until I add things!) is the spindle, while I'm awaiting delivery I want to make sure I know what I'm doing and this is the bit I've been avoiding:)

High level, do I connect up power and the spindle, then go in and set the PD* values , power down and wire up to AXBB-E , then go in and test?

Wiring
The wiring I have based on CharlieRams thead is



Does this look correct ? In that thread Charlie couldn't get 0-10v to work so stuck with 0-5v. Any issue with just leaving the jumper on AXBB on so its 0-5V and setting PD070 to 1 to match the 0-5V control?

Also I'm thinking why is FOR/REV needed, I can't think of a use now for reverse so can I just link DCM and FOR ? Or will I lose the ability for UCCNC to turn on/off the spindle and e-stop?

I'm planning to use 1mm CY 4 core cable - seems like there are differing opinions here, but I'm trying to minimize cable size and 1mm should sustain a max of 8Amps rating and the spindle will use 5A or less in use as Jazz has measured, so gives so overhead for voltage drop etc.

PD Values
This is where I'm a bit stumped, maybe the manual will explain more (probably not) but some blogs etc people set only a couple of values while the sticky here suggests loads.
Is the sticky still correct as of 2020?
Control:
PD001/002 = 1
Frequency:
PD005 - 400
PD004 - 400
PD003 - 400
PD006 - 2.5
PD007 - 1.20

PD008 - 220
PD009 - 15
PD011 - 120
PD014 - 5
PD015 - 10
PD044 - 2
PD045 - 3
PD072 - 400.00
PD143 - 2
PD142 - 7
PD144 - 3000, factory setting is 1440 ->3000 gives correct RPM of 24000 at 400hz

PD070 (optional to 1 for 0-5V rather then 0-10v)

Thanks !

Doesn't matter really you won't hurt anything either way. I just connect everything up then set the settings but I've fitted 100's and confident so just do what you feel most comfortable doing. There's no right or wrong way provided you DONT wire it when powered up.! (like I often do.)

You can actually power up the VFD without the spindle connected and enter the settings on the bench if you prefer, I often do this before fitting into the control box's on machines that are fiddly to access or I'm waiting for other stuff so do it to save time later.

I find 0-10V gives better scaling and more accurate speed than 5V but both work ok and neither is very accurate but for most machines, a few 100rpm tolerance is perfectly fine.

Only connect FOR because these spindles are not designed to run in Reverse, they will run in reverse ok electrically but the collet system isn't designed to run in reverse and will unscrew it's self if put under heavy loads.


1mm/2 cable is perfectly fine provided you are not running very long lengths. Again I've built dozens of machines that are fitted with 1mm and never had any issues.
Like KIT mentioned it helps with the spindle connector because space is very tight. Take your time here and use heat shrink on the pins so they can't touch. Also and this is THE MOST IMPORTANT make sure you fit a Cable strain on the bracket or Z front plate to hold the cable so it takes the pressure off the connector. This is THE single biggest reason why spindles blow up which ties in closely to KIT's poor wiring job advise, fail to do both correctly and it's just a matter of time untill BOOM.!!
