I tried to run this machine.
It have two FSSBs that connect to servo amplifiers. The first one connect to 2 amplifiers which drive 5 servo motors. The second connect to another 2 amplifiers which drive 3 axis servo motors and two servo motors act like spindle. All motors have absolute pulse coders.
I set dogless zero return with absolute encoder. After ref. return only first 5 motors (on first FSSB) remember zero point, 3 others do not (on 2nd FSSB).
Do I miss something?
