Troubleshooting Siemens SIMODRIVE 611 Error 607: Causes, Diagnostics, and Fixes

Troubleshooting SIMODRIVE 611 Error Code 607: Motor Overload / I²t Tripped

1. Error Definition

Error Code: 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.

Step 1: Observe Symptom Patterns

• Does Error 607 occur immediately at power-on? → Likely internal drive short or mains overvoltage.
• Does it occur only during deceleration? → Braking resistor or chopper issue.
• Does it occur randomly while running? → Mains fluctuation or capacitor aging.
• Does it occur with a specific axis? → Mechanical overhauling or motor cable fault on that axis.

10. Conclusion

Resolving SIMODRIVE 611 Error 607 requires methodical troubleshooting focused on encoder feedback integrity and drive electronics. Use the stepwise procedure provided to isolate root causes, apply targeted fixes, and implement preventive measures to reduce recurrence. simodrive 611 error 607

Step 4: Small Modules (No External Contactor)

• If the machine design does not use an external mains contactor (direct mains feed), check for a jumper wire on the Power Supply Module terminals (often across terminals X11 or designated "Link").
• If this jumper is missing, the drive defaults to Error 607 because it cannot detect a "contactor."
