Sm72-2p running problem

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?

 

have you checked the brake?

 

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

 

Yes, I I have checked the brake.
Thanks for the reply.

 

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.

 

Please take t steps indicate before

Otherwise you would take around in the same problem.

 

Could you show us by picture the errors that the machine indicates and the DYN test. Thank you
