V5 Motor Current Limit vs Temperature

[Sylvie]

V5 Motor Temp in Percent?

The original conversion, the one that’s still in the VCS August version, is this. double temp_in_percent = (motor_temperature - 21.0) / (100 - 21.0) * 100; which was then limited to the range 0 to 100% so 0% was 21C and 100% was 100C, we knew these were not the real limits, it was really just a place holder until final numbers were determined. We updated in September to this. double temp_in_percent = (motor_temperature - 20) / 50 * 100; so 0% would be 20C and 100% would be 70C, this m…

The motor firmware will cut maximum motor current in half at 55 degC, to 1/4 at 60 degC, 1/8 at 65 degC and disable the motor completely if it reaches 70 degC.

@jpearman is this still true? Have the values been tweaked since 2019?

after some testing they seem to, but I can’t confirm the 70+ number

Tangentially related, is there a way to find the current draw from the ADI ports?

nothing has changed.
