4. 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 ,
is adjustable from 20% to 100% of the inverter's rated current. A proper con-
figuration 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.
