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 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 overload protection setting.
