The alarm bits are just a 4 bit code(codes are listed in one of the controller manuals), This would require tri-stateable differential drivers on those PWM pins (and knowing when to change dir: DRDY?)
Yes 6-PWMs signals for 6 transistors on the 3phase bridge.
I worked on this about a year back .So If I remember right,the alarm signals are just multiplexed digital signals.No other protocal involved.
hello i am again. s700 have a Fanuc robot, buy blcd picosystem converters. I also have these drivers.
and according to my research are these,,,,,
I share all my data,

These Fanuc servo amplifiers require SIX PWM signals for each axis. If you have 5 motors on the robot (typical) then you would need THIRTY fast PWM channels to drive the 5 axes. Also, the top and bottom transistor of each pair must never be on at the same time, or it will likely blow the transistors. It might be better to just use 3 PWM generators with a pair of deadtime generators each to produce the 6 transistor drive signals. This would get into custom FPGA development.
