Why like this.

Need to know you MMC--likes you have MMC100.2 --open check back of the HMI 

also Pleasze post picture of 810D CCU from display

PR on you should have communication CCU to MMC (PR=PLC RUNNING)

SF on means your drive all no parameters or something wrong in the drive.

Hello! 

Please help me if possible in the following problem: sinumerik 810d led sf is lit and so it remains with error 120008 on the display. I guess I followed the plc reset procedure on the site and led PR is green and the SF led is red, CB led yellow and blinks. For more clarifications, we added 1pictures of machine problems.

thank you.

ps. Excuse English!

hello I have an 810D operating system, the condition of the 810D controller is SF error, before the machine was still fine but after 10 days of rest, the machine reported an error that needed to change the battery.  Then I changed the battery, but the error is gone, but I can't use it
