Kuffs,
I have old Flex software on an old laptop. It very basic and the the drive connects. My problem is I had a motor bearing fail and got the exact motor new. Put it on and I get fault codes? cleared the fault codes Zero and one tries to move them faults. I noticed that who ever set up the drives last time had a a 50A-233 in the description they try to zero but fault. I changed to motor setup to 50N-233 like the name plate now they hold position and won't move at all. Did I erase something. I'm pretty sure they are just slaves to the PC/desktop that runs the program with a I/O card.
