Snow Sun
Apr 19yes, as your said. the FFA and FFB are encoder feed back output for the controller(here are 6563 ); the RDC6563 controller will accept the FFA and FFB as a position feed back and also has a position feed back with a capacitor sensor to detect the height of the nozzle and output a analog speed signal to the servo drive to do a close loop control. For a Z axis live focus control, it is a little bit complex. if possible, pls send me the servo drive datasheet in English my email is :ssh@rd-acs.com
: Hello, maybe someone can help me, after a long time I finally managed to get the Z axis to work. But when adjusting the height, the Z moves down to the material and as it approaches it also moves away, but does not return to the desired height. What am I doing wrong please help. Greetings Matthias
