Simodrive 611 Error 607 Verified May 2026
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
Real-World Case Study
Machine: 5-axis machining center with SINUMERIK 840D and four SIMODRIVE 611 drives.
Solutions and Repair Strategies
Case A: Braking Resistor Open / Damaged
- Solution: Replace with an identical Siemens resistor (or a compatible unit with equal resistance and higher wattage rating). Never operate the drive without a functional resistor on regenerative axes.
- Upgrade option: Install a larger external braking resistor unit if the axis frequently triggers 607 during normal deceleration.
Verify DC Link: Measure the DC bus voltage and ensure the busbar screws are tight. simodrive 611 error 607
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.
1. Defective or Undersized Braking Resistor
The external braking resistor (often labeled like "6SN1113-1AB00-0DA1") is the first line of defense. If it becomes open-circuit (burnt out), disconnected, or has incorrect resistance, the drive has no path to dump regenerative energy. The Siemens Simodrive 611 error 607 is a
To diagnose and resolve the fault, technical support forums like Siemens SiePortal suggest the following:
Module Swapping: If the error persists on a specific axis (e.g., the X-axis), try swapping the control module with a known-good unit from another axis to determine if the fault follows the card or stays with the power section. When to Seek Professional Repair Solution: Replace with an identical Siemens resistor (or
Simodrive 611 components are legacy products, and repairing them requires specialized testing rigs. If troubleshooting points to a hardware failure, it is often more cost-effective to send the module to a certified Siemens repair center rather than attempting a board-level fix in-house, as the power transistors (IGBTs) and gate driver circuits are highly sensitive.
