Hello, The symbol 'S' (system error) usually symbolizes one or combination of the following:
Considering the error message is "PLC Process Control Failure" could be related to: ● Module errors (only for hardware controllers) ● I/O access errors (only for hardware controllers) ● Parameter assignment errors (only for hardware controllers) The error propagation could happen from the connected FbDrive block which needs to be investigated further. (tough to conclude with the current screenshot/information). However, I hope these inputs give you a direction to troubleshoot your issue. You can also refer the 'Error handling' section 2.1.6 in the manual linked here (you can also refer FbDrive's error handling from the manual) -> APL 9.0 SP3 Manual |

Hi, Are you using real hardware? If not, try setting parameter: DataXchg1 to value 16#4 of the Fbdrive block. Do this as well for all channel drivers such as readback value (Pcs7AnIn) |

Hi Oreca, Yes, FbDrive working with SE Altivar 630. Your proposal with DataXchange1 = 16#04 didn't work. |

Hi, OK, have you checked if one of the External messages is active: ExtMsg1, ExtMsg2 or ExtMsg3. One other possibility is that the readback value is outside setpoint limits. Have you checked the RbkWH_Lim and RbkWL_Lim parameters? Otherwise motor feedback or motor protection is a possibility. The Trip signal should be set to 1 which means no active trip. Sometimes because of the Profidrive framework, the trip signal should be inverted that is coming from Fbdrive. Can you share some more information like a print screen from the CFC chart containing Fbdrive and MotSpdCL block in test mode? |

Hi, I cannot see any error in your print screen, only one thing which you can try: - Insert an Or04 block and connect its output to: ATV_In_Out.On. The input of the Or04 should be connected to: M.Fwd and M.Rev. Download and check if this works...
