I’ve been using an odrive 3.6 successfully with a 32V, 10A power supply to control a D6374 motor. I want to run it at higher torques, so have swapped to a 48V 50A Meanwell power supply (an RSP-2400). But now I find the USB connection keeps dropping out as soon as I send a command to move the motor.
I have a USB isolator connected to my PC, and am using the USB cable that came with the odrive. The cable from power supply is about 80cm long, twisted along its length, and the cables from odrive to motor are about 30-40cm long. The mains cable from the power supply is about 60cm long, and I’ve tried to keep it physically separate from the DC output as much as possible. I’ve also tried to keep the USB and DC cables to the odrive as far apart as possible. Other than encoder, motor thermistor and a button connected to RST to act as a stop switch, nothing else is connected. My understanding is that with the USB isolator, I shouldn’t be having an issue with ground loops, correct?
I’d be grateful for any suggestions how to resolve this problem.
