    Hitachi seiki HT-25S lathe Varispeed serwo drive

    I try to repair servopack yaskawa varispeed 626MTII, after power supply fault, I have broken positioning card. I found some pdf for 626MTII but only width simple magnetic sensor positioning card. My card are based on 8031 CPU and using encoder. I found similar card in 626MTiIi pdf but it's not...

    Deckel FP3a CNC2101 stop on 00 error code

    I think that eprom are ok. I dump it and disassembly, code look good. Using logic analyser I check that NMP52 board wait for communication from npc52, checking control register of mc6821 in loop. I found this adres and check in program code. Npc52 - drive keyboard and respond to simple command...
