Hey everyone, I'm experiencing a problem with my Pflex 755 where it goes into fault 9 for "Transistor Over Temp" when stopping the motor. Has anyone encountered this issue and found a solution before? Any help is greatly appreciated!
Ensure that all heatsink fans are functioning correctly during operation. Monitor the IGBT temperature in both Celsius (P942) and percentage (P941), as well as the drive temperature (P944 and P943). Make sure to regularly check these parameters for optimal performance and safety.
I had a similar issue with my Pflex 755 a while back. What worked for me was double-checking the cooling system of the motor drive. If it's a bit dusty or not working efficiently, it can lead to heating issues and display a "Transistor Over Temp" fault. A good clean-up and performance check on the cooling system could potentially resolve the issue. Be sure to also inspect the ambient temperature and your heat sink installation. If these don't help, you might need professional support.
Hey! I’ve run into a similar issue with my Pflex 755. In my case, it turned out to be related to the cooling or ventilation around the motor and control unit. I suggest checking the airflow and ensuring no dust is blocking any vents. Also, consider if the motor is overloaded or if there’s any excessive wear on the motor itself. Just some things to look into—hope it helps!
I've faced a similar issue with my Pflex 755 and found that it often relates to insufficient cooling or dust accumulation around the transistors. I cleaned out the cooling vents and made sure the environment wasn’t too hot, which helped reduce the frequency of the fault. Have you checked the airflow and cooling system? It might also be worth looking at the load you're placing on the motor during stops. Sometimes a sudden stop can cause excessive heat buildup.
Hey! I’ve had a similar issue with my Pflex 755 before. It could be related to the cooling within the drive or the settings regarding how quickly the motor stops. I found that adjusting the deceleration rate helped alleviate the problem a bit. Also, make sure that the ventilation around the unit is clear to prevent overheating. Hope this helps!
Hey! I’ve dealt with a similar issue on my Pflex 755, and it turned out to be related to inadequate cooling or dust buildup around the transistors. Make sure the ventilation is clear and consider adding a small fan if it's in a confined space. Also, checking the settings for the thermal overload trips might help; you could be able to adjust them safely. Hope that helps!
