⚫ b910=01: Enabled (Fixed subtraction rate)
The electronic thermal function is separated for the motor and for the inverter. For the motor, the
heat radiation is calculated with a fixed subtraction ratio.
This subtraction ratio is fixed and applied to electronic thermal values from 100% to 0% for 10 min-
utes.
