If you have a dual-axis drive module or multiple identical drives in the same cabinet, swapping components is the fastest way to isolate the fault.

If you operate a multi-axis machine, you can leverage adjacent drives to isolate the problem.

: A broken or disconnected motor power cable (the orange cable) or a loose connector.

A common pitfall is relying strictly on no-load bench tests. A damaged LT-module might pass basic static resistance tests with a multimeter, only to trip with Error 607 immediately when forced to deliver dynamic torque under production loads. Step-by-Step Troubleshooting Checklist

Error 6 on Simodrive after changed motor bearings - SiePortal - Siemens

To clear this fault and restore your system, it is crucial to understand its primary causes and the systematic steps required to get your machine running again. What is the Simodrive 611 Error 607?

The alarm can be triggered by a wide range of physical or configuration faults. It can manifest in different ways—intermittently or permanently, at startup or after a period of operation.

Consult the official Siemens Support portal for detailed hardware manuals, wiring diagrams, and community threads discussing similar fault codes.

. This occurs when the drive attempts to reach a setpoint by outputting maximum voltage, but the measured motor current remains below the expected value. Root Causes The most common reasons for this fault include: Physical Disconnection

: A faulty control module (the card that plugs into the power unit) can also be the root cause. The most efficient diagnostic method is module swapping :

: For new installations or service jobs, verify that the configuration parameters (like P1106) are set correctly for the power section.

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).

: Disconnect the motor from the load to see if the drive can run without error. If it can, the problem is likely a mechanical jam in the machine axis.

If the internal 24V mechanical brake fails to release completely, the motor fights its own brake, overloading the current loop. 2. Motor and Power Cable Issues
