Heidelberg sm52-4 year 1997

Dear There
hope all have a nice time, while i need help with the sm52-4 while I have error as I show you on the attached photos, I appreciate if any one can guide me to the write way to fix this error while the technician tell me may the bet-con card defective.

 

Hi dear sir, what is wrong with the machine before we get to DYN test!
Thanks a lot

 

Hi
I just move the machine from place to another and but it took 3 month without installation the machine and when the technicians installed the machine it give this error shown in photo

 

Hi sir
- check brake tension try to clean the encoder blow with compressed air and put it back in its place
- try to clean the brake, the springs and loosen if there is rust.
if all goes well
-try to check the brake control on the UVM card at a specialized electronics technician, or change encodor
Good luck sir

 

when starting do you hear the brake release

 

Hello dear sir please check the cable or connections! I need to know what the interface displays.

 

no sound just when I press the run button just beeps hear and stop, no break sound release

Please check 48V DC on UVM card perhaps is defective

 

Check care full encoder(main motor) carefully.
As per code problem seems in encoder/connection

 

I asked him about the brake release sound and he confirmed that there is no brake movement so I think the encoder error is a consequence

 

As per pix send above blt con 7fdf (dyn) comes immediately after power on.
It means probelm in main motor encoder/connector.
Error mean is all sensor giving same signals

 

can you give me more explanation

 

Did you check the 48v dc on the uvm card ??

 

For main motor two cable (1 big one Nd second small round cable) to plugged in property.
Normally round connector encoder cable remain loose
Just remove and tight again
