Frequency Relay How It Works, Application

Does the frequency converter have thermal relay protection

The electronic thermal relay (ETR) in the frequency converter is used to protect the motor from overheating by calculating the motor temperature based on actual current and speed. It allows programmable options to stop the motor, reduce output, or ignore the condition. Observe the setting value of the overload protection and modify it if necessary.
