    Hello everyone
    An error f11 on simoreg 6RA2275 which is related to a tachometer
    We have replaced the tacho with a new one and still the same after Running the machine it stopped and shows f11
    We even changed parameters l33 related to the error
    what else could be the problem ?
    Thank you

    Do you test cable from encoder to driver ? Can you measure 5v that should be in the encoder ?

    hello,
    you can measure the Tacho voltage at main drive X1 pins 1 and 3 OR X003 pins 5 and 6. The voltages would be like this Tacho signal from motor 15000 rev/h = 3000 rev/min. =180VDC
