I like this bit.

Is that from delivery or dispatch?

I have ordered one of thease TB6560 boards back on the 27/10/2009, before I asked about them here.

I have no idea how long it is going to take to get from china to me with all the dam royal mail strikes on going.

The eBay ad says that it should only take upto 6-10 business days, but I will have to wait and see.

I went for the TB6560 over the TA8435H as it is ment to support upto 36volts, and the TA8435H can only support upto 24volts.

I am going to be using this board with my Astrosyn MY103H702 stepper motors.

I am looking at running 34volts to try and get as much speed out of the stepper motors as possible.

I will report back once I have got the board.

Hi

I'm interseted to see how you get on, I've been looking at them myself but put off by the fact its all on one board and max 36v.
But £50 ish for 4 axis with opto sounds like my budget

Well the post and been and gone today, but no sign of my parcel yet.

Oh well it looks like I will not get unto next week now.

I have been reading the so called bad english manual for the driver board to work out what DIP Switch settings I am going to need.

I am only intrested in switches 1-4.

Switches 1-2 are for the current setting, 100%, 75%, 50%, 25%.

Is this a case of 3.00amps, 2.25amps, 1.50amps, 0.70amps, or does the board self sence the current and when at idle or hold, hold the current at said % of the stepper motors max current.

Next is Switchts 3-4 for the Buffer, the manual just has, Fast, 25%, 50%, Slow, so at a guess I need to set it to Fast.

Then the last two switches 5-6 are for the step modes, this I understand.

If you look at the datasheet here , pages 9 and 10 you will see that switches 1-2 are the torque current settings relative to maximum current(default 100%) and switches 3-4 are the Decay Modes (default I suspect should be fast). The max current is actually set by the big resistors on the board, but its hard to tell what colour the stripes are, should be Brown, green, silver, silver which is 0.15ohm for 3.3A.

irving2008: Thanks for your reply, I have just been hunting around the net to see if I can find better pictures.

So far all I have been about to find are thease two pictures.




To me it looks like the current sence resistors are, Brown, Brown, Silver, Gold, 0.11ohm 5%.
If that is right we are looking at 4.5A.

Well the board has just this sec turned up.

I was worng about the current sence resistors, they are infact, Orange, Orange, Silver, Gold, 0.33ohm 5%, so thats a current limit of 1.51amps.

I have not done any testing yet, so I will report back with how I get on.
