Concerns products with the Order Nos.:                                      

                                                                            

6ES5 848-6FC12   Modular PID and Fuzzy Control software package             

6ES5 848-8FA.1   Modular Closed-Loop Control software package               

6ES5 848-7FA.1   Modular Closed-Loop Control software package               

                                                                            

                                                                            

                                                                            

_Reason for the change:_                                                    

                                                                            

On page 4-61 of the English manual it says: "The Controller OFF             

function has priority over all other controller modes. It can be            

used as a protective function." .... ""0" is always output when             

the speed controller is switched off."                                      

                                                                            

This is not always true because in the controller modes Manual              

and SHAWD=1 the current manual value is output instead of "0".              

                                                                            

_Upgrading to revision level A03:_                                          

                                                                            

An upgrade is available from your local Siemens office. Please              

specify the ID No. or Serial No. of the original software on                

your order to be eligible for the special price.                            

                                                                            

_Note:_                                                                     

                                                                            

The same fault also occurs with the Modular Closed-Loop                     

Control package (Order No. 6ES5 848-8FA.. and 6ES5 848-7FA..).              

In view of the fact that this software will be replaced by the              

Modular PID and Fuzzy Control package, no fault correction will             

be carried out.
