Connecting Delta Asda-b2 to Axbb via line driver type

Postby KlausLim » Tue Feb 14, 2023 1:36 pm

Good afternoon guys.
I have some questions about connecting delta b2 step dir signals to axbb.
I would like to use the linear method.
Because if you connect through an open collector, the pulse frequency will be only 200 kHz.
Is it possible to connect for example positive signals (37, 41), as in the photo, to non-isolated outputs (O9-O17 on Axbb), and put negative ones (39, 43) into 5V0?

I don't really want to use isolated outputs (O2-O8) for open collector connection.

Also, can I connect the fourth axis in a linear way using the outputs O1-O9 on Ucsb?
I was going to put positive signals on them and minus signals at 5V0 on Axbb.

Thank you in advance :D

how fast do you need your machine to go?
i use 200Khz and set drives gearing to 300 pulses per mm.
never run out of speed yet! machine rapids at 40m/ minute

the leadshine servos i use while listed as 200khz single ended, accept way faster signal input than that without errors.

I have this configuration: ball screw 5mm, for more accuracy, 5 servos for 3 axes + 4th axis.
A friend of mine advised me to have more than 200 kHz to compensate for the small step of the ball screw.
But this is not the main thing, speed is not so important for me.
I just have a problem that if I connect the motors through an open collector, then I will not have enough pins on Axbb (O2-O8).

I found that my Leadshine AM882 stepper drives, while rated for 250Khz, actually ran better at the 400Khz setting.
