LOW RPS with Odrive Pro and D5312s 330KV

Hello,

I am using the Odrive Pro with the D312s 330KV motor and an MSP-200-24 power supply. I have a picture of my power configuration below. I am using the Odrive onboard encoder without the thermistor. When viewing the Desmos calculator with a 24V bus, I am suppose to be able to reach 115 rps in a free air configuration.

My problem is that when I run the motor at no load I am only able to get 14 turns/s before a DC_BUS_OVER_VOLTAGE Error. I dont have access to a larger power supply currently but do I need to increase the voltage to reach higher speeds. Is the problem caused by a lack of a brake resistor. I have tried using a S1 with a brake resistor and the results were marginally better. What is the problem with my configuration / setup?

Hi! What encoder are you using?

I’ve been using the encoder built into the ODrive Pro and the Odrive S1. I have no external encoder.
