General Mach Discussion / Re: hello there - help please, how do you do the light sensor limit switch - 3 wires

« on: February 02, 2023, 06:08:14 PM »

on my controller
i have 12 volt out
ground
and the input

i think

i think i get it

pin 1 12 volt in
pin 2 to ground on controller board
pin 3 is the input pin out of switch -  to x++ = = == x++ means either way of x axis up or down, x-- the otehr way and the other switch
so i have 6 ground wires going in

or thats how it would work with a proximetry switch

ahh
so what i really need to look into is the release dates of for exampl
200w panasonic systems
yaskawa sets
and mitsubishi
mitsu for example
Mitsubishi HC-MFS23 200W AC Servo Motor
gate on the box
2015

thats not ancient.........
find the matching drive to the hc-mfs23
which is a
Mitsubishi MR-J2-20B Servo Drive
then go - no used ones, move on.....
etc

yaskawa
Yaskawa SGM-02A312 200w motor    SGDA-02AP fm 200w driver

yes i shall do the cheap stepper motors 4 phase bi polar parrallel and the cheap drivers to get it going
then search for a set of three of the above

make sure they all work off the machine and swap them in.

what I mean is..... is that an offer of help regards the actual connection and setting up of the drives and the tuning
I think thast what stopped me fitting the minas a4 set i had to my last machine, it was all a bit too specialist

what is the real kick in the pantaloons is
I had three sets of panasonic minas a4 200w motor and drives

the motors share this machines 50mm mounting and bore - its the exact same, I originally thought they were a servo motor when i measured them as nema 23 is 56mm on centres

anyways

i sold them years ago, but I might treat myself

then it will be
bolt on botors
connect to drives
connect controller to drives

vroom vroom

does anyone bother with for example 200w little servos and drives on a tiddly machine

there is no information on 200w panasonic minas motors and drives used in hobby cnc
or mitsuboshi
or yaskawa

shame really
ok so a set of motors and drives is 500 odd - used
thast not out of this world

....................................................................

no, sod that
3 nema 23's 41mm long 8 wire bipolar £21
3 3a stepper drivers £27
one 24v 10 a psu £30

total 78

3 panasonic minas a5 200w servo motors and drives £600 - 700
hmm

edit
- not to self
DO NOT BUY panasonic minas a5 200w servo drive part number
MADHT1507
DO NOT buy panasonic minas a5 motor 200w part number

yes, you went through the 32 bit to 64 bit software no worky on me new pc tarbarkle - them youngling don't know they are born.

so yes, 1997 = its all a bit not worth it, the otehr thing is, when looking on the ebay and there being real lots of them for sale means no one has gotten their heads around a re-porpoise
seems a shame to cut the cables from them too, BUT The shielded cable 'appears' to be worth more than the motors them selves


some of them in my control box = easy

no, the cross is an x I put on it for x -axis
the machine was complete
 the 'really' funky things is I have bought two complete machines
this is a small mill
the other is a double wire hot wire cutter for foam cutting - cutting foam to keep you still in a thingbob machine
i think this machine has a light box draw that you pull out and use as a digitiser type thing - still junk nowadays, but hey ho


was on the ebay for ages, typically 5 miles up the road and got the first one in my little car
going to get the other on the weekend

like you say, the first thing I did was pull it apart as it was in an enclosure - check the dates on the giblets
its all really high quality stuff, but I fear its from 1997
I have already bought the new little nema 23's 8 wire
i have some 3a drivers that I know how to set up
and I have a network cable 3 axis breakout board
a mach 3 license

would have been nice to use the motors, I did check the data sheets and as soon as I saw they were ten core new it was out of my realm, or league,
then i checked the price of them on ebay....................

pic of controller
rs232 so a simply rs232 parallel input, i could simply work out the i/o and connect it to mach3?
