Drive Motor Overload Protection
Set parameter 02-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motor overload
protection is UL listed and in accordance with the NEC and CEC.
■ 02-01 Motor Rated Current
Setting Range: Model Dependent
Factory Default: Model Dependent
Set 02-01 to the full load amps (FLA) stamped on the nameplate of the motor.
■ 08-05 Motor Overload Protection Selection
The drive has an electronic overload protection function (OL1) based on time, output current, and output frequency, which protects the
motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an external thermal overload
relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
