1. Check the hardware connection: First, check the hardware connection related to the shaft, including cable and motor connection. Make sure all connections are secure and correct.
2. Check the parameter settings: check the parameter settings of the shaft in the PLC program, including the motor type, encoder resolution, speed and acceleration values, etc. Ensure that these parameters match the actual installed equipment.
3. Check the power supply: ensure that the power supply required by the shaft is stable and meets the specification requirements.
4. Check the programming logic: check the logic parts related to the shaft in the PLC program, such as motion control instructions and limit switch detection. Ensure that the logic flow is configured correctly and can run normally.
5. Check the alarm information: check the alarm information of PLC200 configuration software or PLC, know the specific error code or alarm information, and refer to relevant manuals or documents to find the corresponding troubleshooting methods.
6. Simulate and test the fault: If possible, try to simulate or manually operate the fault of the trigger shaft, so as to diagnose and eliminate the fault more accurately.
If the above steps can't solve the problem, I suggest you contact Siemens' technical support or seek relevant training and consulting services for further help. Technical support personnel can provide professional guidance and suggestions to solve the errors of two axes in PLC200 configuration.
