Simodrive 611 Error 607 2021 -

607 Designation: Mains phase failure / Missing Phase Description: Error 607 indicates that the Simodrive 611 power supply module has detected a loss of one or more phases in the incoming mains power supply, or a significant voltage imbalance between phases. In simpler terms, the drive is not receiving the correct 3-phase power required to operate.

If you are currently troubleshooting this error on a machine, let me know:

Mark and swap the power output cables and the matching encoder control cables at the drive module face between the failing axis and an identical working axis. Boot up the machine carefully. : simodrive 611 error 607

If the , high-resistance bottlenecks prevent fast current delivery to the power transistors.

: Check that the DC link busbars are tight and that the voltage is present and stable. Inspect Control Card 607 Designation: Mains phase failure / Missing Phase

When your Siemens Simodrive 611 throws an (often appearing as Fault 607), it signals an issue related to the DC link voltage, frequently indicating that the DC bus voltage is missing or has dropped out entirely. Troubleshooting this error safely requires a structured approach to prevent equipment damage.

: Check the yellow LED on the Infeed Module to ensure the DC bus is operational. Ensure the DC link busbar screws are tightened according to the Simodrive 611 Manual . Boot up the machine carefully

Cycle power to the drive (24 hours off to discharge DC link) or send a “Reset” command (e.g., reset key on SINUMERIK panel). If logic fault remains, use SimoCom U to perform a “factory reset.”

The plug-in closed-loop control card sitting on the front of the module may have corrupt parameters, dried-out capacitors, or failing logic chips. D. Incoming Power and DC Link Instability

), the error may persist even after mechanical and cable checks. Troubleshooting Steps

Ensure power is disconnected and locked out (LOTO) before performing physical inspections. Wait at least 5 minutes after disconnection to allow DC bus capacitors to discharge.
