heidelberg speedmaster sm 52 error code

Hi guys
I have a problem with the heidelberg speedmaster sm 52 .2
error code with motor symbol with number 14 As shown in the picture.. What is the meaning of this symbol?
Finally, I hope someone can help me with a table of error codes for the machine, thanks

 

good evening dear sir, check if a court point button (red button) must be activated

 

There are three emergency buttons in the machine and all of them work correctly and appear on the screen when it works. And the main emergency number his code 15 works as well

 

Good evening dear sir, if you say that the buttons course fist works properly, please check the motor brake!

 

good evening.
No problem with the brakes, I think this is a general parking alarm, but I don't know what this symbol means

 

I was faced with a problem like this but I don't remember.

 

the emergency stop switch of a peripheral device connected to the interface adapter is locked
