Set the Motor Current - The inverter has thermal overload protection that is designed to protect the inverter and motor from overheating due to an excessive load. The inverter’s uses the motor’s current rating to calculate the time-based heating effect. This protection depends on using the correct current rating for your motor. The level of electronic thermal setting, parameter B012, is adjustable from 20% to 120% of the inverter’s rated current. A proper configuration will also help prevent unnecessary inverter trip events.

Read the motor’s current rating on its manufacturer’s nameplate. Then follow the steps below to configure the inverter’s thermal overload protection setting.
