Verify that the drive module is getting fed properly from the central power supply.

An extreme mechanical bind or seized axis gridlocks the motor. The drive pushes maximum current to break the bind, fails, and times out with Error 607. 3. Feedback and Control Loop Failures

Whether the error happens or only when the axis attempts to move .

If you determine that your Simodrive 611 hardware needs replacing or servicing, it is important to use reliable sources.

Siemens SIMODRIVE 611 Error 607 is a classic “can’t start” fault that intimidates many due to its safety interlock nature. Yet, with a methodical approach starting at the 48V power supply and following the signal chain, it is one of the most solvable errors in the Siemens drive family.

This paper examines error code 607 on Siemens SIMODRIVE 611 servo drive systems. We analyze possible causes, diagnostic procedures, and step-by-step remediation strategies to restore safe operation. The goal is to provide technicians and engineers with a concise, practical reference for troubleshooting and resolving Error 607 while minimizing downtime and avoiding equipment damage.
