    Dear all, i hope you have a good day.
    We have a machine SM74-5 year of construction 2000, at starting up after cutting the power off a symbol like a man appears at the screen. I don't understand what this symbol mean. After we start the machine the machine don't start automatically but after i check the error messages the machine can be start automatically. I went to check the INIT and DYN and the errors where as follows:
    INIT t = 0 :
    S-SAK FFEF
    S-HAK 5 M1 FFF5
    S-SSK 1 M9 FFFC
    DYN t=0:
    A-FEU 1 FFFE
    The problem of M1 and M9 is not a affecting the process but the problem of SAK and FEU is not clear for me.
    could you please help me in this issue.
    Thanks in advance.

    A-FEU is due to the encoder of the main motor of the machine. S-SAK checks the battery of the card.
