Record current state:
Attempt to rotate the machine axis manually using a hand wheel or wrench on the ball screw. It should move smoothly without binding.
The internal Hall effect current sensors on the LT module can drift, falsely reporting a current saturation to the control card. 4. Control Module (Regelung) Faults or Parameter Mismatch simodrive 611 error 607
Given the vintage nature of the Simodrive 611 series, if your diagnostics point to an internal LT module or control card failure, reaching out to a specialized CNC electronics repair depot for component-level refurbishment is often the fastest, most cost-effective path to getting your machine back in production.
Ensure that the DC link voltage (typically 600VDC or more, depending on input) is present and stable when the drive tries to start. Record current state: Attempt to rotate the machine
: Isolate the machine from the main power supply. Follow Lockout/Tagout procedures. Wait at least five minutes for the drive's DC link capacitors to discharge before touching any components.
