Motor Temperature

FALCON supports motor temperature monitoring using an external thermistor connected to the motor thermistor input. Both NTC thermistors and linear PTC sensors (PT100/PT1000, KTY81/KTY84) are supported. The temperature is calculated from the thermistor resistance and is broadcast over CAN in the 0x630 - Temperature Data message.

info

All motor temperature parameters are located in the /motortemp/ folder.

Parameters​

thermistor_r0 [Ohm]​

Resistance of the thermistor at 25°C. Set to 0 to disable motor temperature measurement.

thermistor_k [K]​

Thermistor coefficient. The sign selects the sensor type:

  • Negative — NTC thermistor. The value is the NTC Beta coefficient in kelvin (e.g. -4050).
  • Positive — linear PTC sensor (PT100/PT1000, KTY81/KTY84). The value is interpreted as 1/alpha in kelvin (e.g. 127 for KTY81-110).
