Simodrive 611 Error 607 Jun 2026

| Condition | Action | | :--- | :--- | | Only braking resistor open | Replace resistor only | | Braking chopper failed | Repair module (cost-effective) | | Multiple aged capacitors bulging | Replace module or perform full recap | | PCB burned near DC link terminals | Replace module (repair cost exceeds value) | | Error appears on multiple axes simultaneously | Investigate mains supply or common DC bus |

In Siemens terminology, Error 607 is a . 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.

If the error persists after checking cables and mechanics, the control module LT (Power) section may be defective and require replacement. Siemens SiePortal 4. Safety Note Always wait at least 30 minutes simodrive 611 error 607

If the drive powers up briefly without tripping:

Coolant or oil ingress into the motor terminal box bridges the power terminals, altering electrical resistance. C. Drive Module Failures | Condition | Action | | :--- |

A: Yes, but the error will return immediately unless the physical overvoltage condition is resolved. Cycling power resets the latch, not the cause.

The quickest way to rule out a mechanical jam is to separate the motor from the load. Uncouple the servomotor from the ball screw or gearbox. Safety Note Always wait at least 30 minutes

If the fault appears only during rapid acceleration/deceleration, increase the ramp-up time (P1060) or reduce the torque limit (P1120). This masks the symptom but not the root cause—use cautiously.

The plug-in closed-loop control card sitting on the front of the module may have corrupt parameters, dried-out capacitors, or failing logic chips. D. Incoming Power and DC Link Instability
