Learning Protection Features
Protection features provided by the H100 series inverter are categorized into two types: protection
from overheating damage to the motor and protection against the inverter malfunction.
6.1
Motor Protection
6.1.1
Electronic Thermal Motor Overheating Prevention (ETH)
ETH is a protective function that uses the output current of the inverter, without a separate
temperature sensor, to predict a rise in motor temperature to protect the motor based on its heat
characteristics.
