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.

b910=02: Enabled (b911 subtraction rate)
The electronic thermal function is separated for the motor and for the inverter. The heat radiation is
calculated with the subtraction ratio set in b911.
Set the b911 value according to the thermal time constant of the motor.

b910=03: Enabled (b912 time parameter subtraction)
The electronic thermal function is separated for the motor and for the inverter. The heat radiation is
calculated with the time parameter set in b912.
Set the b912 value according to the thermal time constant of the motor.
