Greetings everyone, I am excited to share that I am utilizing the latest Kinetix 5100 system in my facility. I have successfully configured the movement in Speed Mode and have set up the Analog signal transmission from my programmable logic controller (PLC) to the drive. After tuning the motor, I am currently testing the system by sending the analog signal to the drive. I have noticed that at low speeds, the motion seems inconsistent and jumps between positions, while at high speeds, the movement is smooth and constant. I am seeking advice on how to adjust the velocity loop to ensure a consistent motion as the analog signal increases. Any suggestions or tips would be greatly appreciated. Thank you.
If you are experiencing issues with Stribeck friction, also known as stick slip, especially at low speeds, seeking assistance through online forums or communities can provide valuable insights and solutions to overcome this problem. Share your experience and seek advice to effectively address this issue.
Hey there! It sounds like you've already made some solid progress with your Kinetix 5100 system. As for the issue of inconsistent movement at low speeds, tweaking the Velocity Loop Gain might be your best bet. By increasing it gradually, you can improve precision at low speeds. However, keep a close eye on the motion while doing so to prevent any potential instability. It's also a good idea to enable filtering to enhance motion smoothness. Lastly, consider the implementation of an S-curve acceleration profile which can provide a smooth ramp up, reducing the jumpy motion. Hope this helps and happy tuning!
Hi there, congrats on your progress with the Kinetix 5100 system! About the inconsistency at low speeds, it could be an issue of resolution of your analog signal or a low torque output from your motor at low speeds. For the former, check the signal's resolution and consider amplification if it's too low. For the latter, ensure your tuning is correct. In tuning, issues can arise from poor inertia match between the load and motor. When it comes to adjusting the velocity loop, it sounds like the system may require a more responsive control at lower speeds. Consider tightening your velocity loop by increasing the gain (P or PI). But do remember, too aggressive gain adjustments might incur instability, so increment it gradually. Also, using a notch filter to suppress mechanical resonances might help, though it might be more advanced. Hope this helps and best of luck!
It seems like you may be experiencing problems related to low speed instability. This is not uncommon when working with servo systems. In such cases, aspects such as friction, backlash or even electrical noise can affect the readability of the encoder, making low speed regulation challenging. I would recommend trying to increase the Integral Gain (Ki). This can often enhance the performance at low speeds. However, be careful to avoid setting it too high as it can cause the motor to oscillate. I would also suggest double checking your wiring for any loose connections which could cause intermittent signal loss. Hope this helps!
Hi there, it seems like your system could be experiencing some instability at lower speeds due to gain settings in your velocity loop. It's worth checking if your tuning parameters are optimized for your system's characteristics. You might want to experiment with reducing the velocity loop gain to smooth out the motion at low speeds. However, be careful not to set the gain too low, as this could result in a sluggish response at higher speeds. Furthermore, try enabling a notch filter, it can help eliminate specific resonant frequencies that might be causing these issues. Lastly, ensure your feedback system is working optimally. Inaccurate feedback can also result in system instability.
Hey there! It sounds like you’re off to a great start with the Kinetix 5100. For the inconsistent motion at low speeds, I'd recommend checking your velocity loop settings—specifically, the proportional and integral gains. Sometimes, increasing the integral gain can help with steady-state errors at lower speeds, but be careful not to set it too high, as this can lead to overshoot or oscillation. You might also want to experiment with the damping settings and make sure the acceleration and deceleration rates are suitable for the application. Keep us updated on your progress!

Specifically, increasing the integral gain can help improve the response at lower speeds, but be careful not to make it too aggressive, as that could lead to overshooting or oscillations. Also, consider implementing a low-pass filter on your analog signal to smooth out any noise, which can contribute to those position jumps. Good luck with your testing!
