Error 607 [2021] - Simodrive 611

The Siemens Simodrive 611 error 607 is a critical diagnostic message typically associated with a Contouring Error (also known as a following error). This fault occurs when the difference between the setpoint position (where the machine thinks the axis should be) and the actual position (where the axis is) exceeds a predefined limit set in the machine parameters. Primary Causes

Q3: How do I clear Error 607 after fixing the cause?

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.” simodrive 611 error 607

3. Diagnostic and Troubleshooting Steps

WARNING: Hazardous Voltage. Ensure power is disconnected and locked out (LOTO) before performing physical inspections. Wait at least 5 minutes after disconnection to allow DC bus capacitors to discharge. The Siemens Simodrive 611 error 607 is a

Misdiagnosis: First technician replaced Z-axis power module ($2000) – fault returned after 3 days. Relay Failure on PSM: The internal relay on

C. Internal Drive Failures

  1. Relay Failure on PSM: The internal relay on the Power Supply Module PCB that sends the 24V signal to the external contactor coil has failed.
  2. Input Circuit Failure: The digital input on the PSM that reads the feedback signal is damaged.

Frequently Asked Questions (FAQ)

Q: Can I clear Error 607 by cycling power?
A: Yes, but the error will return immediately unless the physical overvoltage condition is resolved. Cycling power resets the latch, not the cause.

Many third-party shops (e.g., Artus, Radwell, Global Electronic Services) offer flat-rate repair for SIMODRIVE 611 modules ($500–$1500). Siemens also offers exchange service but typically more expensive.

The Control Card: If you are running a multi-axis system and have an identical axis on the same machine, attempt to swap the control card (plug-in module) to see if the 607 error migrates to the other axis. If the error moves, your control card is likely defective.
