When I shut down the controller, the PWM values turn into NaN

Support ODrive S1 Support

Hello,

I want to use the Odrive S1 motor driver in velocity mode, controlled by PWM signals from a Myrio 1900 controller. The motor driver operates correctly when the system is powered on, but when I shut down the controller, NaN (Not a Number) values are measured as PWM signals. I have confirmed that the controller outputs a PWM signal of 0 before shutting down. However, immediately after shutdown, NaN values are input to the motor driver, causing the motor to behave erratically.

I’m curious about how to resolve this issue. Thank you.

Have you confirmed your ODrive S1 is updated to 0.6.8? This was a recent bug that should’ve been fixed.
