Sinumerik Alarm 22070 TO unit %1 Please change tool T= %2 into magazine. Repeat data backup
%1 = TO unit
%2 = T number of tool
The alarm can only occur when the tool management function is active in the NCK. (TOOLMAN = tool management) A data backup of the tool/magazine data has been started. During the backup, the system detected that tools are still located in the buffer magazine (= spindle, gripper, …). During the backup, these tools will lose the information which defines the magazine and location to which they are allocated. It is therefore practical – assuming that the data are to be stored exactly as before – to ensure that all tools have been deposited in the magazine before the data backup!! If this is not the case, some magazine locations will have the ‘reserved’ status when the data are loaded again. This ‘reserved’ status must then be reset manually. For tools with fixed location coding, the loss of the information allocating their location in the magazine has the same effect as a general empty location search when they are returned to the magazine.
