Good Day All.
eBay now have the TB6560 Stepper Motor Driver Boards, in 3,4, and 5 axis.
I have ordered my self ones of the 4 axis versions.
I see that there is a topic about the eBay TA8435H Stepper Motor Driver Boards here but I wanted to start a new topic to stop cross posting or going off topic.
I have gone for the TB6560 over the TA8435 due to the fact that the TB6560 is ment to be able to run voltages of upto 34volts.
I am going to be running Astrosyn MY103H702 stepper motors in Bipolar Parallel, 1.4amp per phase.
Reading the datasheet for the TB6560 chip I can see that the current is set by current sensing resistors.
As I have not yet got my board I can only go by looking at the pictures, and if I am right the current sence resistors are, Brown, Brown, Silver, Gold, 0.11ohm 5%, If that is right we are looking at 4.5A, but the TB6560 chip is only rated to 3.5 amps peak.
Then you have the 6 dip switches, switches 1-2 are once again for current limit, 100%, 75%, 50%, 25%.
Are we looking at a current % of 3.0amps, 3.5amps or 4.5amps?
So how do I set up the board for use with my stepper motors.
Does anyone have one of thease board, or can anyone clear a few things up for me.
Thanks for your time.
Best Regards.
