My application requires maintaining constant tension on a fiber production line and I’m considering using an O-Drive kit in torque/current control mode as a direct drive to achieve this. I’ve searched the documents and see only cursory references to how to set current control.
I would like to know what are the ranges of torques I can achieve with this mode, the resolution and if I will get constant torque or if torque amplitude will have some temporal (or positional ripples)? I’m particularly interested in a low-speed domain (0.1 to 5 RPMs) and low torque values (<0.001 Nm).
Can anyone comment if they have used these motors in a constant current/torque mode and what are the performance ranges?
