Simodrive 611 Error 607 < LATEST ✪ >

A: Yes, if resistance matches and wattage is equal or higher. However, ensure the mounting and thermal dissipation are adequate. Undersized resistors will fail within hours.

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: Yes, if resistance matches and wattage is equal or higher

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. For complex or recurring cases, download the or

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.

Introduction The Siemens Simodrive 611 is a cornerstone of industrial motion control, powering countless CNC machines, milling centers, and robotic systems across the globe. Known for its robustness and modular design, it is not immune to faults. Among the various alarms that can bring production to a screeching halt, Error 607 is one of the most common—and often misunderstood.
