Understanding and Troubleshooting Simodrive 611 Error 607 The is a specific fault indicating that the current controller output is limited . This occurs when the drive system cannot impress the required setpoint current into the motor, even though it has reached its maximum voltage output.
: Measure insulation resistance from each phase terminal to the motor frame. Any reading indicating a short to ground requires a motor rewind or replacement.
For more technical specifics, you can refer to the official Siemens SiePortal support forums or the SIMODRIVE 611 universal Function Manual . Simodrive 611: error 607 etc. - Siemens SiePortal
: Inspect the motor power cables for breaks and ensure the terminals on both the motor and the Simodrive module are tight. simodrive 611 error 607
). The readings should be perfectly balanced and typically low (under a few ohms).
This error triggers when the internal drive processor detects that the commanded current setpoint cannot be established in the motor, despite the power section delivering maximum voltage output. Specifically, if the actual current reading ( Iactcap I sub a c t end-sub
: Use a digital multimeter to check the resistance between the phases ( Any reading indicating a short to ground requires
When your Siemens Simodrive 611 throws an (often appearing as Fault 607), it signals an issue related to the DC link voltage, frequently indicating that the DC bus voltage is missing or has dropped out entirely. Troubleshooting this error safely requires a structured approach to prevent equipment damage.
Error 607 rarely points to just one isolated component. Instead, it represents an equilibrium problem where the drive cannot satisfy the motor's power demands. The primary causes fall into four distinct categories: A. Mechanical Overload and Jams
The most common cause is a physical open circuit between the inverter module and the servo motor. If one of the three power phases (U, V, W) is severed, loose, or corroded, the drive cannot balance the current loop. 2. Tripped Uce Monitoring Circuit - Siemens SiePortal : Inspect the motor power

: First, they checked the motor supply cable and connector for any loose phases or damage. A missing phase can cause the motor to struggle under load, triggering the 607 alarm.
Markus wiped his hands on a rag. “The new IGBT is rated for fifty thousand hours. The solder joints are better than factory. I’d say… longer than the contract.”
Consider reaching out to authorized Siemens parts distributors or experienced industrial electronics repair houses to have the drive unit refurbished. If you are currently facing this issue, could you tell me:
