Procedure in case of an error

•For deeper analysis of the error case are following data necessary:

Diagnostic file (before Restart command) -> see Diagnostic File.

Load Error Data -> see Load Error Data.

•Check the corresponding error code and execute the necessary steps

•To leave the Error Control Mode, the Error Recovery function can be used or Restart Controller see Services.

7 | 0 | 7 | Wrong ident code axis 3 AND axis 2 AND axis 1 |
7 | 7 | 7 | Do not operating mode active |

1) Mechanical movement problem:

•Check for differential pressure

•Remove foreign object in movement area

•Eliminate tight movement

•Repair mechanical failure
