Simodrive 611 Error 607 · Premium Quality
) prevents the controller from neutralizing steady-state errors efficiently.
Damaged or poorly shielded encoder cables can introduce signal noise or intermittent connection drops, especially during high-speed movements.
Thermal cycling looses power terminal screws over time. Periodically check the tightness of the DC link busbars and motor output lines.
Error 6 on Simodrive after changed motor bearings - SiePortal - Siemens simodrive 611 error 607
Error 607 can be attributed to three main categories of failure:
While the drive is dismantled, visually and electrically inspect the snubber capacitors and resistors for signs of burning, leaking, or physical damage. Operating the drive with failed snubber components is dangerous and should be avoided. 4. Evaluate the Infeed Module
Error 607 on a SimoDrive 611 system typically indicates a problem with the encoder or the feedback device connected to the drive. The specific error code may vary slightly depending on the version of the drive and its configuration, but generally, Error 607 points to an issue with the motor feedback system. Periodically check the tightness of the DC link
) can cause the loop to overshoot and saturate its output buffer. 5. Internal Axis Card Hardware Failure
DC, focus your troubleshooting on the Infeed/Regen (NE) module or main incoming line supply chokes. Step 2: Perform Static Motor and Cable Tests Rule out the external power train components.
Aging capacitors, degraded current-sensing resistors, or failing transistors on the High Standard or High Performance control card inside the module can cause inaccurate internal readings, falsely triggering the fault. Step-by-Step Diagnostic and Troubleshooting Guide In Siemens terminology
When a drive module displays "607" on its 7-segment display, it indicates that the drive has tripped due to an —essentially, the motor has been operating above its rated current for too long, causing a calculated thermal overtemperature condition.
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.
