I have been testing the L6480 with a NEMA 17 and 23 motor. I got the NEMA 17 to work by entering the Ke , mH and the ohms in the BEMF tool. Once I got the 17 working fine I started working on the NEMA 23. I tried the 23 valves in the BEMF tool and it will not go over 600steps/s. The NEMA 23 is a 8 wire parallel bipolar motor, is there anyway this could be causing a problem? Just as a test, I disconnected the coils in parallel. so I only had 4 wires hooked up and it worked fine.
Any ideas?
