Figure 31 – Example of thermal protection with speed reduction
If the speed reduction is not sufficient to stop the temperature rise, and the NTC reaches the
shutdown temperature, the motor is turned off, and the Inverter temperature reduces
naturally. After the NTC temperature drops down to the turn-on limit, the compressor
restarts automatically, and the motor speed follows the setpoint (Figure 32).
