Cause : Internal braking resistor thermistor temperature monitoring fail (size 0 only) comes when no internal brake resistor is installed, set Pr 0.51 (or Pr 10.37) to 8 to disable this trip.
If an internal brake resistor is installed:
1. Ensure that the internal braking resistor thermistor is connected correctly.
2. Ensure that the fan in the drive is working correctly.
3. Replace the internal braking resistor.
