Offizielle Schritte zur Fehlerbehebung
%6 [Cause of error] - The SPLC program has requested an illegal safety function over PP_AxGrpStateReq in the ApiToSafety (symbolic memory interface of SPLC to the core safety software SKERN). ERR-ID = Exact information ObjId = Axis group causing the error Param = Depends on the ERR-ID ERR_ID: 100: Requested safety function is not supported Param = Requested safety function 200: The safety function SLI_S was requested for a axis group that is not of the spindle type. Param = No meaning 300: The safety function SLI_2, SLI_3 or SLI_4 was requested for an axis group that is of the spindle type. This safety function is not allowed for spindles. Param = Requested safety function 400: The safety function SLS_4 or SLI_4 was requested for a axis group and the function is not enabled. Param = Requested safety function 401: A direct change is requested from the safety function SLS_2, SLI_2, SLS_3 or SLI_3 into the safety function SLS_4 or SLI_4. This direct change is not allowed. Parameter = Requested safety function 402: A direct change is requested from the safety function SLS_4 or SLI_4 into the safety function SLS_2, SLI_2, SLS_3 or SLI_3. This direct change is not allowed. Parameter = Requested safety function 500: The SPLC requested the safety function STO or STO_O for an axis group whose drives are still in the control loop. The requested safety function can be requested only if all drives of this axis group have been switched off. Parameter = Value of the required safety function [Error correction] - Check the ERR ID: 100 - Use only safety functions that are supported with this software level. 200 - Request the safety function SLI_S only for axis groups with spindles. 300 - For spindles, request only the SLI_S function. 400 - Do not request a safety function or enable the safety related operating mode SOM 4 in machine parameter permitSom4. (Check the preconditions for enabling) 401 - Switch off the drives between the change of safety function and request SOS for at least one cycle. 402 - See 401 10/2023 [539] 500 - Switch-off with the stop functions over PP_AxGrpStopReq. - Inform your service agency
