tb6560 power

[Denrow]

I have a 3 axis tb6560 board . and wanted to know how to power the 12v power source for the board. is it just a 240v power source to the 12v ???

You need a DC power supply - either regulated or unregulated should be OK.

Such a power supply will take your 240 v AC line power and convert it to 12 volts DC.

Depending on the characteristics of the motors that you will be using, you may want greater than 12 volts, but you may not want to go much more than 24 volts at the high end (although some people do).

i have a 12v power supply for the board . but im unsure if i just get a plug straight from the mains and connect the live-neutral and earth to the 12volt box i have which came with the package i bought.

[James Newton]

Wouldn't that be a question for the people you bought the package from?

[Denrow]

it is and i have they just said look at the pic on ebay but thats no help.

my 12v converter has:

live - neutral -earth - com -com -com - +v - +v -+V so not sure as to how that all goes together in to the control board . ive looked online and cant find anything

I'm somewhat hesitant to make a recommendation inasmuch as my direct knowledge of UK AC power wiring is limited to having once or twice plugged my electric shaver into the outlet in a London hotel room's bathroom.

It was a very fine hotel with a very fine bathroom and a very fine outlet, and so I have fond memories of my time spent in London, as stressful as it was (due to the challenging business purpose behind several of the trips), but I will defer to someone closer to you to address UK electrical hookup questions.

Hi Denrow ,

I would use two switches to control the mains supply to your switch mode power supply

a two pole switch illuminated rocker switch (or rotary switch) as the main
on /off switch

also depending on the E stop switch you use

1 or 2 normally closed switch contact(s) on your emergency stop switch
as a Quicker and easier to use on /off switch
and another switch contact to trigger an E stop to the control system

switching just the live is OK but live and neutral is better

for me , only having a software E stop is not good enough
while an E stop ,when the control software is responding ,
will stop the steppers quicker

you need to remove the mains supply as well
since the pc may have stopped responding
you could have an over load due to a fauty power supply or stepper driver


don't switch the DC supply to the stepper drive board
that will damage the stepper IC's

on the power supply ,the three common terminals are connected together
and the three positve terminals are connected togerther
this makes it easier to connect the 3 pairs of supply wires to three individual stepper drivers
with the all in one board you only need to connect to
one - common terminal and one positive terminal

Hi John

Thanks very much for the help , its has been very useful.

I was intending to put a rotary isolator switch from direct mains into dc convertor but the switch i have isnt straight foward . it has l1 & l2 on opposite sides of the switch and at the rear has earh (x2) and neutral (x2) as ive never come across these switches before its a bit of a problem have already asked guys at work and looked online for wiring diagram but cant seem to find one so i im thinking just a normal swich instead.

Doorknob -
I in fact had the same issue when i visited Texas for a month , The hosts i stayed with found it quite funny at how huge our plugs were , thier said '' Where the hell is that ment to go'' when i told them it was a plug they found it funny as hell.

Hi Denrow ,

A picture of your switch may help some one to identify the switch terminals

modern switches are usually made up of a number of sections
each comprising of two switches that are forced open by the cam
the two switches are wired as a single double throw switch

yes the UK plugs are some what larger but for a good reason

PS for non UK forum members
unlike the two pin shaver plugs ,the UK 13Amp plugs are fitted a 1" HRC fuse
very often its a 3A , 5A or 13A to suit the appliance and its mains cable
( 1A, 2A, 7A and 10A fuses are also available)
the 13A sockets are connected to a ring circuit thats protected by a 30A fuse or circuit breaker
