Simodrive 611 Error 607 |verified|

If an IGBT suffers an internal short circuit, an open gate, or an over-temperature breakdown, its collector-emitter voltage ( Ucecap U sub c e end-sub ) spikes out of spec during conduction.

on the 7-segment display) occurs when the motor cannot reach its setpoint speed or position because it has hit its maximum voltage output, yet it is still drawing maximum current. Effectively, the drive is "maxing out" trying to move the motor but failing to do so. Siemens SiePortal 2. Common Causes Phase Failure:

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. simodrive 611 error 607

The control card plugged into the power section may be malfunctioning, incorrectly interpreting feedback signals.

Internal current sensors on the drive can drift, reporting excessive current even when actual load is normal.

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 . Primary Causes If an IGBT suffers an internal short circuit,

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.

Check the orange motor cable for damage, burns, or abrasion, especially near connectors.

Step 3: Test the MotorUsing a megohmmeter (Megger), check the insulation resistance of the motor windings to the ground. A low reading usually indicates a motor that needs to be cleaned or rewound. Siemens SiePortal 2

If you have a multi-axis system, try swapping the control module with a known working one from another axis to see if the fault follows the module.
