How to Resolve Siemens Motor Encoder Problem on Drive F31115

Question:

Hello team, I am currently experiencing a problem with my Siemens motor. Oil seeped into the motor while it was running, which prompted me to open the motor encoder and clean it. However, after reattaching the encoder, an alarm keeps triggering on the Siemens drive F31115. I have tried setting the encoder position according to the markings in the pictures, but the issue persists. Any suggestions on how to properly set the encoder position to resolve the continuous alarm on starting F31115 would be greatly appreciated. Thank you in advance. Best regards,

While I may not have specific knowledge about this particular servo motor, I have encountered other servo motors with an integrated encoder (such as Bosch Rexroth) that required re-phasing to the motor after removal. This process involved a proprietary procedure and software adjustments. Ultimately, we had to replace the motor and send the faulty one for repair.

Hi there! You've already made a good start by cleaning the motor encoder. However, the alarm could be due to incorrect alignment during reattachment. Ensure the markings align precisely as they were prior to disassembly. Moreover, don't forget to check the wirings and connectors for any damages as they might also trigger false alarms. For the encoder settings, you might have to refer to the Siemens service guide specific to your motor model. It should provide you with information about ideal encoder positions. Hope this helps and you're able to resolve the issue soon!

Hey there! It sounds like you’ve done a thorough job cleaning the encoder, but the persistent alarm can be frustrating. One thing I’d suggest is double-checking the encoder's alignment and making sure it’s seated properly—they can be a bit finicky. Also, have you tried resetting the drive parameters after reattaching the encoder? Sometimes, the system needs a reset to recognize the changes. If that doesn’t help, looking at the wiring for any possible damage or loose connections might be a good next step. Good luck, and I hope you get it sorted out soon!

Hey there! It sounds like you’re dealing with a frustrating issue. When it comes to resetting the encoder position, make sure you’re following the exact alignment and torque specifications outlined in the Siemens manual, as even slight misalignments can lead to alarms. Additionally, have you tried a full power cycle after reattaching the encoder to clear any cached faults? If the problem continues, checking the wiring and connections to the encoder might help, as oil might have affected them as well. Good luck!
