I hooked up a usb converter that can do 1M serial. Sent the output to a 75als191 differential driver and tried to feed the REC leads on the panasonic drive. . still get encoder error.
Out of ideas. Perhaps my inter character time is too long. I was sending and ascii ctl-g or a "c" to simulate the commutation signal.
Anyone actually know what the Pansonic drive wants to make it self happy?
