    Good day.

    I have a problem with the Roland 300 machine.
    The machine does not start. After turning on the sound signal, then I press the button to turn on the main relay and start the engine for 1 second and STOP.

    The screen shows an error:
    UWR: Die Maschinendrehzahl ist unzulassig

    or

    HA: Drehzahlerfassung

    There is error 38 on Beumuller BKF12

    I checked:

    Wiring between the incremental encoder (1024) => BKF12, I also made a new cable.
    Second used encoder (1024). I checked the next encoder (3600) and changed the parameter to BKF12 to 3600 (P143). Always start the machine, only 1 second.
    I checked the BKF12 parameterization
    I checked the brushes on the Baumuller GNAG132 engine, they are all very good, the motor was completely repaired 2 years ago.

    Is this a problem with BKF12?

    Sorry for my English.

    Regards Kuba

    Is not a problem with BKF12
    Check the machine sensor. Check that the degrees change correctly. The same is the case with the wrong direction of travel. Is the machine installed now or has it been running for a long time?
    PP check parameter 142 with what is written on the mаin drive parameter disk.

    The machine stops every dozen or so degrees, about 30 deg.
    Can a problem also arise with the second absolute encoder?
    The error description signals to check the motor armature. Could this be a problem if the engine starts for a while?

    Thank you very much for the response.

    The machine worked for a long time, earlier there was an occasional error.
    There used to be a similar problem and the brushes were turned off.

    If the main machine sensor does not work correctly, this causes an error. Turn the machine 1-2 turns manually. Observe the degrees on the display on 1st u.

    I have encoder 5V 1024

    What is RODIMO?

    Error station 7 was from several years.

    What do you think about this error?

    What else should I check for error 38 on BKF? This is the most important problem.

    Dear sir:
    Check this :
    [BKF12] K1 / [K3] and K2 / [K1] on main drive activated; deactivated only when machine speed is „0“
    K2 [K1] (main drive) closes bypass via +Ax -A343 K1 and K2 (necessary for 4-quadrant-run)
    K1 / [K3] (main drive) closes the circuit to -K022
    UWR-Relay on -A566-board (-K3) is activated
    -K022 is activated
    With -K022 (contactor break release) micro switch -S804 is closed
    High-signal on PIN 18

    Blessing

    1. Does machine turn after signal? Turn one degree or more or it does not move at all?
    2. Did you have some power problems in printshop?

    Check fuses under BKF, 250A

    Yes, the machine rotates after a signal, the engine rotates 1/2 to 1 turn and STOP.
    It rotates about 30 degrees
    In fact, there was a voltage drop on that day, but earlier this error also appeared at start-up times.
    The fuses are OK, I checked at the beginning, the engine started.
    Brake releases (operation K022)

    Armature winding - 0,5 Ohm
    Field winding - 80 Ohm
