Hi! The F11 error on your SIMOREG 6RA2275 suggests issues with the tachometer circuit, such as incorrect wiring, polarity, or unstable output. Double-check the wiring and polarity. Verify the tachometer output at various RPMs using a multimeter to ensure it’s consistent and meets specifications, like 20V at 1000 RPM for DC units. Inspect the mechanical coupling for alignment issues and ensure the CNC controller's signals properly match the drive states. If the issue persists, it might require advanced diagnostics or parameter tuning to resolve

The tacho is new and the wiring is good so is the polariy and the voltage
I started to think its in the drive electonics or parameters
Im not sure yet .
