Need Help!- 5718L-03P Stepper Motors

[eqalizr]

Hi everyone!
This is my first post, but I have been on the site for over 2 years attempting to gleen information to build my own CNC router. I recently completed my first, only to inadvertly leave my driver on for 14hrs overnight which burned up to of the HP steppers I was using. The board the TB6560 appeared to be OK. I found a good deal on 3 5718L-03 LIN steppers, but didn't notice the amps/phase was 4.2A.

My question is, Will the TB6560 be able to support the LIN 5718L-03 or will I have to change the controller?

Thanks in advance.

The limit for that driver is about 3A.

I understand (I think) but wouldn't that just underpower the motors but still work?

Your driver will probably be fine as long as you select a current setting resistor below the max, but most likely the real maximum for a TB6560 is around 2.5A which is far below your target.

Excuse my ignorance but does that mean I don't need to limit the output and can connect directly to the driver?
