Simodrive 611 Error 607 -
In the Siemens Simodrive 611 system, (often displayed as on the drive or on the Sinumerik CNC) indicates that current controller output is limited
4. Incorrect I²t Time Constant (P1025)
Measure encoder supply voltage:
Power Module or Control Card FailureThe most frequent culprit is a hardware malfunction within the Simodrive 611 unit itself. A failing LT-Module (Power Section) or a glitchy High-Performance control card can misinterpret feedback signals or fail to output the necessary voltage, triggering the limit error. simodrive 611 error 607
Inside the power module, an IGBT transistor (the "brake chopper") turns the braking resistor on/off. If this transistor fails short-circuit, the resistor will overheat and burn open; if it fails open-circuit, the resistor never engages. In the Siemens Simodrive 611 system, (often displayed
