Simodrive 611 Error 607 -
In the Siemens error code hierarchy, translates to:
The modular design of the Simodrive 611 relies heavily on solid busbar continuity. Error 607 - SiePortal - Siemens
“Not somewhere,” Markus sighed, pulling a worn schematic from his back pocket. “In the drive itself. The IGBT module. It’s the heart of the thing. When 607 pops up, it means the transistors that shape the current to the motor have essentially welded themselves shut.”
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: simodrive 611 error 607
Are there any showing on the drive or the CNC screen? Share public link
: Unplug the orange motor power cable from both the Siemens Simodrive 6SN11 LT-Module and the motor housing terminal box.
If the internal 24V mechanical brake fails to release completely, the motor fights its own brake, overloading the current loop. 2. Motor and Power Cable Issues In the Siemens error code hierarchy, translates to:
In practical terms, the drive is "maxing out" its effort to move the motor but isn't seeing the expected electrical response, which often leads to related secondary alarms like "Contouring Error" on the CNC interface. Primary Causes of Error 607
: Disconnect the orange motor power cable at both ends. Use a digital multimeter to verify phase-to-phase impedance directly on the motor terminals.
The underlying triggers for Error 607 span across the power module, physical cabling, and internal circuit safety relays. 1. Motor Disconnection or Missing Phase If one of the three power phases ( The IGBT module
If error 607 occurs immediately after a new installation or during commissioning, incorrect parameters are a likely cause. For example, the "calculate motor data" or "calculate controller data" functions might not have been executed properly, or there may be an issue with the speed/position feedback encoder. A Chinese reference also suggests that a faulty encoder or poor shielding on its cable can lead to "motor runaway," a symptom sometimes associated with Error 607. Another configuration issue can arise if the torque reduction via analog inputs or PROFIBUS is set to zero, which can cause the system to misinterpret it as a request for zero torque (see Causes for Error 608).
: Internal hardware failure, specifically in the current sensing circuits or the transistor modules, can trigger this error even if the external wiring is perfect.
The Insulated Gate Bipolar Transistors inside the Simodrive power module handle high-voltage switching. A shorted or degraded IGBT cannot deliver balanced current.
