    Fanuc series 21-T

    I changed the battery of a device after changing 1815 number 1 to 0 it became like this????
    417 servo alarm: 1 axis DGTL PARM
    417 servo alarm: 2 axis DGTL PARM
    750 SPINDLE SERIL LINK ERROR
    751 SPINDLE-ALARM DETECT (AL-64)

    This alarm occurs when the nth axis (axis 1-8) is in one of the following conditions.
    The value set in parameter No.2020 (FANUC motor type) exceeds the specified limit. (The value setting corresponding to the motor model is wrong)
    The value in parameter No.2022 (motor rotation direction) is not set, and the correct value is (111 or -111).
    Parameter No.2023 illegal data (the number of speed feedback pulses per motor rotation is lower than 0, etc.).
    Parameter No.2024 illegal data (the number of position feedback pulses per motor rotation is less than 0, etc.).
    Parameters No.2084 and No.2085 (flexible excitation gear ratio) are not set.
    Limit value or discontinuous value exceeding {1 to number of controlled axes} (parameter No.1023 (servo axis number) contains a value outside the range of 1 to the number of axes, or an isolated value (for example, 4 is not 3).

    My brother, I am a beginner, can you explain to me better to solve this problem. I did not see these errors, but after changing the battery and entering the 1815 parameter and changing the number 1 to 0, I received these errors. Thank you????

    You need to set APZ for each absolute axis ie XZ on a two axis lathe. (Bit 4)

    1) Power Up
    2) Switch to MDI Mode
    3) Hit offset key twice and change Parameter Write Enable (PWE) from 0 to 1
    4) Hit feed hold button to silence the parameter write alarm
    5) Hit System Key, should bring you to the parameter page by default
    6) Type 1815 and hit the "No. SRH" soft key (number search) should bring you to Parameter 1815
    7) There will be a row for each axis (xyz) and under the APZ column, change from 1 to 0 for one of the axis.
    8) It should automatically bring you to the message screen, telling you to power off (go ahead and power off and wait 15 seconds)
    9) Power back up, Alarm should sound (silence with feed hold button) switch from MDI to hand jog and jog the axis along its travel.
    10) After you've jogged back and forth for several inches, jog toward the zero reference alignment mark, slightly pass the alignment mark (but don't go more than an inch beyond or you will overtravel)
    11) Bring it back until the alignment marks match (just eyeball this)
    12) Switch back to MDI mode and go back into SYSTEM>PARAM> 1815 and change the APZ back to 1
    13) It should ask you to power off again. Power Back up and repeat steps again for any other absolute axis (if needed)

    The above was on CNCZone in 2020.

    Brother, I have the problem of the axle not working and it shows me 1axis / 2axis instead of showing me the x axis / z axis
