Simodrive 611 Error 607 [work]

The individual power modules (LT-modules) rely heavily on the shared DC bus bar supplied by the Infeed/Regenerative module (IR module or UI module). If the main 315-Amp DC link fuse inside the drive housing has blown, or if the busbar screws have loosened, the drive cannot pull the current it demands. 4. Control Module or Memory Card Corruption

Partial short circuits or ground faults cause excess current.

If you are currently facing this issue on your machine, I can help you narrow down the exact component failure. Please let me know:

is a DC link overvoltage alarm that demands immediate attention but rewards systematic troubleshooting. In 70% of field cases, the solution is a $200 braking resistor replacement or a simple parameter adjustment. In the remaining cases—chopper failure, capacitor aging, or mechanical overload—more in-depth repair is required. The individual power modules (LT-modules) rely heavily on

| Condition | Action | |-----------|--------| | Mechanical binding | Repair mechanics | | Incorrect parameters | Reconfigure drive | | Motor winding short | Replace motor | | Drive current sensor failed | Replace drive module | | Intermittent 607 (once per week) | Likely parameter or cooling issue |

Use a digital multimeter to measure across the to confirm the voltage is safely below 15V before touching anything. Control Module or Memory Card Corruption Partial short

Based on Siemens documentation and field reports, Error 607 commonly correlates with one or more of the following:

: They opened the bus cover to inspect the DC link busbars . Loose or corroded connections here prevent the drive from getting the stable voltage it needs to power the motor.

: A broken wire, loose motor connector pin, or failed internal conductor in the heavy-duty power cable prevents current from flowing evenly across all three phases.

The Siemens 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 .
