    Hi everyone,
    I have a problem with a compact sm74 2p.
    When I run the press some times machine doesn't run smoothly and there is a dreadful sound.
    When the press runs with the impression on, if the speed pass 6000 the trouble appears.
    When we want to increase the speed it seems there is a delay.
    There is an error in the dyn test that says the press and motor speed are incompatible.
    I have checked the motor belt and it doesn't slip.
    Does anyone has any idea?

    Hi sir;

    You must go to the shop machine, the motor, for maintenance time, and exchange the Encoder

    Every electric motor, must have maintenance every year ; for LUBE+BALL BEARING+Varniz. etc

    Good luck

    Blessing

    I have checked the encoder sensors l, they work properly. The sound is not from the motor but I'm planning to test it.
    Thanks for the reply.
