Hello.
I have some troubles with Berger Lahr D900.50 stepper motor drive board.
The motor was running fine for some time but after weekend motor just moves back and forward. Drive board shows no error also on LED lights.
I have 5 of those boards in my machine, I changed the position of the boards and problem goes with board. So it can't be motor fault.
Please advise me, how could I fix the board.
Regards,
Marek
