If the drive detects that it has pushed its voltage or current output to its absolute maximum limit for too long—and yet the motor is still not reaching or maintaining its targeted state—the drive triggers Fault 607 to protect itself and the machine from catastrophic thermal or mechanical failure. 2. Common Root Causes of Fault 607
The power section of the SIMODRIVE 611 (LT-module) might be damaged or faulty.
: If multiple axes are present, swapping the control module or power module with a known working one can help determine if the hardware itself is failing.
Wait at least 5 minutes for the DC link capacitors to discharge safely. simodrive 611 error 607
A loss of gating/triggering signals coming from the control card to the semiconductors. 3. Absence or Degradation of DC Link Voltage
The Siemens Simodrive 611 is a cornerstone of legacy CNC automation, powering countless machine tools worldwide. However, aging hardware inevitably encounters faults. One of the most disruptive issues operators face is , which indicates a "Current Control Output Limited" condition. When this fault occurs, the drive module safely shuts down, bringing your machine tool and production line to an immediate halt.
Is this happening on a or dual-axis power module? If the drive detects that it has pushed
607 Designation: Mains phase failure / Missing Phase Description: Error 607 indicates that the Simodrive 611 power supply module has detected a loss of one or more phases in the incoming mains power supply, or a significant voltage imbalance between phases. In simpler terms, the drive is not receiving the correct 3-phase power required to operate.
can send "funny" signals that make the servo behave erratically and hit its limits. Faulty Control Module
collector-emitter voltage monitoring circuit. This circuit constantly watches the health of the internal Insulated Gate Bipolar Transistors (IGBTs). : If multiple axes are present, swapping the
Ensure that the contouring error limit (tolerance) hasn't been set too low for the current mechanical state of the machine.
: Ensure all motor phases are connected and the orange power cable is intact.
