    Question 1994 Mori CL-25 with Yasnac LX3 controller 366 error

    We recently acquired this machine when power is put to it, it does turns on, but we have get a 366 alarm PG Error (s) This is Pulse Generator error for the spindle. I checked the connections as stated in the manual in the control panel but everything seems fine and connected. Any idea of what and where I should go to see if I can correct this error?

    this is from the manual

    4.2.14 ALARMS361, 362 AND366 (PG Disconnec- disconnection check of A, B and C phases from
    tion Error) PG and check by PG input comparison at the
    time when TGONsignal from Servopack turns ON.
    They perform 2 types of checkup: Signal wire
    Trouble
    Disconnection or
    contact failure of
    signal wire between NC
    unit and servopack
    Failure of PG detector
    circuit connection
    No shorting plug connector even without
    spindle PG.
    Servopack failure
    PG failure
    Setting failure of
    TGONsignal detect
    level for Servopack
    (Abnormal case)
    Check Method
    .
    .
    .

    Check for looseness and removal of
    MB20board’s connectors CN1 (X-axis),
    CN2(Z-axis), CN3(spindle) and/or
    CN4(spindle PG).
    Check looseness and removal of
    Servopack connectors.
    Perform wiring check according to
    Connection Manual.
    This type of alarm results when main
    power is applied though result of check
    for above item 1 is normal.
    Shorting plug connector to CN4at CPU
    module is required for such specifications without spindle PG.
    ● Check if
    m#1288 D7=1
    (X-axis TG ON)
    #1289 D7=1
    (Z-axis TG ON)
    occur at motor stop.
    “ If alarm occurs above the speed to
    turn ONTGONsignal, it may be PG
    output signal failure of Servopack.
    “ If alarm occurs above the speed to
    turn ONTGONsignal, it may be failure
    of PG.
    This type of alarm results when position
    detector PPS is low. Motor may reach
    running speed at TGONsignal detect
    level in case of a large speed change
    ratio with an external detector (such as
    Inductosyn, linear scale).
    Solution
    ● Correct looseness and/or
    removal of connectors.
    “ Correct wiring as necessary.
    Replace MB20.
    Contact YASREP.
    Mount shorting plug
    connector.
    Replace Servopack.
    Replace PG
    This is a rare case.
    But, change TGONsignal
    detect level of servopack
    to 12% from the standard
    ~.

    I have the same machine with the same error code.
    Did you find the problem and get it working?
