: A broken wire, loose motor connector pin, or failed internal conductor in the heavy-duty power cable prevents current from flowing evenly across all three phases.
A physical crash can jam the mechanical assembly, physically locking the rotor.
Some systems route the pulse enable through external safety relays. A tripped overload relay, open door switch, or high motor temperature can pull the signal low. simodrive 611 error 607

Use a Megohmmeter (Megger) at 500V or 1000V to test insulation resistance from each phase to the motor chassis ground. Any reading below 10 Megohms indicates insulation breakdown or moisture ingress.
“You want to rebuild the power module?” Lena asked, eyes wide. A tripped overload relay, open door switch, or
Jumper X111.663 to X111.664 temporarily (with extreme care) to test if the fault is external. Do not operate the machine – just test the interlock.
By systematically ruling out mechanical binds, cabling faults, and motor issues, you can isolate Error 607 and return your Siemens-controlled machine to service with minimal downtime.
Error 607 usually points to encoder/feedback related issues but can stem from multiple layers (mechanical, electrical, firmware, parameter). A systematic diagnostic approach — verify wiring, power, signal integrity, parameters, and hardware — minimizes downtime. Where component-level repair is needed, use certified parts and follow Siemens service guidance.
