Simodrive 611 Error 607 May 2026

Internal current sensors on the drive can drift, reporting excessive current even when actual load is normal.

This step requires electrical expertise.

At its core, Error 607 signals: "DC link overvoltage" (also described in some documentation as "Regenerative feedback monitoring" or "Overvoltage in the intermediate circuit"). simodrive 611 error 607

To put it simply, the SIMODRIVE 611 has detected that the voltage in its internal DC bus—the central power reservoir that feeds the drive’s inverter stages—has exceeded safe operating limits. In a typical 3-phase AC drive system, the rectifier converts incoming AC into DC (usually around 565–620V for 400V systems). Error 607 triggers when this voltage rises above a critical threshold (typically > 820V DC).

This isn't a "warning" level; it's a protective shutdown. The drive is essentially saying: "I am about to self-destruct, so I'm shutting down immediately to save the IGBTs and capacitors." Internal current sensors on the drive can drift,

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.”

No. The enable interlock is for safety. Forcing the drive to run with missing pulse enable can destroy IGBTs and the motor. Internal Drive Issues:

This error can be caused by external power supply issues or internal drive component failures. The most common causes include:

A less intuitive cause: A phase-to-ground short in the motor cable can create asymmetric voltage spikes that reflect back into the DC link, causing an overvoltage condition. This often triggers 607 alongside other faults like 608 or 314.
