Never ignore intermittent 607 faults. What happens once a week will eventually happen every cycle, often taking out the entire power module. Use the diagnostic roadmap in this guide, prioritize safety, and restore your machine’s reliability.
A: Not instantly, but repeated overvoltage events stress the DC link capacitors and IGBTs. Continued operation with a faulty braking system will lead to catastrophic module failure. simodrive 611 error 607
When the voltage exceeds approximately (depending on the specific module variant), the drive immediately triggers Error 607, shuts down the output stages to prevent damage to the IGBTs and capacitors, and displays the alarm. Never ignore intermittent 607 faults
If your machine control panel has just displayed “Fault 607” or “Alarm 607” on the Simodrive 611 power module, you are likely dealing with a critical drive malfunction. This article dissects every aspect of this error, from its root physical causes to step-by-step diagnostic procedures and proven repair strategies. In Siemens terminology, Error 607 is a DC link overvoltage fault . It occurs when the internal DC bus voltage of the drive inverter rises above the maximum permissible threshold. Under normal operation, the rectifier converts AC mains input into DC voltage (typically around 600V DC for a 400V AC system). The drive’s internal logic monitors this voltage constantly. A: Not instantly, but repeated overvoltage events stress
For complex or recurring cases, download the or contact Siemens Technical Support with the exact module type (e.g., 6SN1123-1AA00-0HA1) and firmware revision.
Replaced braking resistor – no change. Replaced power module – error returned after 2 weeks.
A: Most likely internal drive aging (capacitors) or a chopper transistor that intermittently fails to turn off, dumping excess voltage into the DC link. Conclusion Simodrive 611 Error 607 is a DC link overvoltage alarm that demands immediate attention but rewards systematic troubleshooting. In 70% of field cases, the solution is a $200 braking resistor replacement or a simple parameter adjustment. In the remaining cases—chopper failure, capacitor aging, or mechanical overload—more in-depth repair is required.
