Markus nodded to Dieter. “Run a dry cycle. Slow.”
The exact of your Simodrive module (e.g., 6SN1123...).
: Check the yellow LED on the Infeed Module to ensure the DC bus is operational. Ensure the DC link busbar screws are tightened according to the Simodrive 611 Manual .
If internal drive fault suspected:
A common scenario: A vertical milling machine with a heavy spindle head. When the operator executes a rapid downward move and then an emergency stop, the spindle head tries to decelerate. The kinetic energy of the heavy axis, combined with gravity (which pulls downward even during deceleration), overwhelms the braking resistor. Error 607 appears.
If the axis is seized or requires immense effort to turn, repair the mechanical way-guides, bearings, or braking system. Step 2: Inspect the Power Cables and Motor
Use the CNC's diagnostic screen to check if the drive is hitting its current limit (often linked to Fault Code 6 on related modules). For detailed technical documentation, you can refer to the Siemens SiePortal Support Forum parameter numbers simodrive 611 error 607
It should read approximately under normal conditions. If it sits significantly lower during an axis move, focus your attention on the Infeed/Regen (NE) module or incoming 3-phase line voltage. Step 4: Swap the Control Card (Axis Cross-Test)
Excessive heat degrades the internal capacitors on Simodrive control cards and degrades the thermal paste behind IGBT modules. Ensure cabinet air conditioners and fans are functioning perfectly.
“No,” Markus replied, raising his cup. “It said help me . And you did.” Markus nodded to Dieter
The (often visible on the LED display as E-A607 , E-B607 , or CNC alarm 300607 ) indicates a "Current Controller Output Limited" fault. This critical hardware-protection error triggers when the drive control module attempts to force the maximum allowable current into the motor, but the system is physically unable to establish or maintain that current level.
Follow this structured diagnosis sequence from easiest to hardest to isolate whether your fault lies in the cabling, the motor, or the drive electronics. Step 1: Safe Volumetric & Mechanical Checks
Error 607 on a SimoDrive 611 system, while potentially disruptive, can often be resolved through systematic troubleshooting. By checking the encoder and its connections, verifying the encoder settings, ensuring a stable power supply, inspecting mechanical components, and resetting the system, you can typically identify and fix the issue. If the problem persists, it may be necessary to consult with a technical support specialist or a qualified service technician who has experience with SimoDrive systems. : Check the yellow LED on the Infeed
Before blaming the specific axis drive module, verify the shared power backbone. Measure the voltage across the DC link terminals ( bus) using a digital multimeter safely.
