SM74-4 L

Hi expert
I have problem with our SM 74-4 L it's can't run, inching and crawling speed is okay. But if we start run before reach 2600 SPH it's suddenly stop. I try clean the belt I thought it's slip. But after we do it still the problem occurs.

 

is this press a perfector?

 

No, it's straight

 

It comes to a hard stop? What about error codes?

 

MOT 7F7F dyn test

 

"induced motor voltage stays below the setpoint values ". May I suggest you check your incoming voltage, and the outputs of your secondary transformer?

 

Okay then I ask our electrician to check it...thanks for the suggestion

 

Hi,
Check the belt, it may slip over the pulley because of oil and dirt. Clean belt and pulley with washup solution and apply anti-set off powder on belt. It absorbs oil and drop off from the belt when get dry.

Good luck,

The problem already solve. I replace the motor brake encoder, and the machine starts run....
So if there's you guys find same problem with me you can check it first...
