Hi y'all,
This issue is not directly related to an NI control issue, but I was hoping someone may have had the same issue as me and knew where to start.
I have a brushless rotary motor from Harmonic Drive Systems (Model: FHA-25C-50-US250-A) connected to a torque sensor which is being read through an NI DAQ. The motor controller is also given a simple position command from the NI analog output.
When the motor is on (and holding a position) there are these weird voltage spikes being read on the torque sensor (see attached picture). These spikes occur with a period of 4.25 seconds, and cannot be simply filtered out. I've tried all the basic shielding/grounding solutions I could find online to no avail.
I don't expect someone to provide a magical solution, but this is my first time using a motor system (besides some introductory stuff from school), so I am unfamiliar with how to even begin troubleshooting the issue.
Any assistance, or even a redirection to a more appropriate forum would be much appreciated. The manufacturer doesn't have any lines of support, so I'm stuck in the deep end trying to resolve this issue for my lab.
Thanks!
