6 -60 Motor Overload ProtectionYou can protect the motor from overload using the Inverter's built-in electronic thermal overload relay.Related Constants* 1. The factory settings depend on the Inverter capacity. The values for a 200 V Class Inverter of 0.4 kW are given.* 2. The setting range is 10% to 200% of the Inverter's rated output current. The value for a 200 V Class Inverter of 0.4 kW is given.Con-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torE2-01 Motor ratedcurrentSets the motor rated current in 1A units.These set values will become thereference values for motor pro-tection, torque limits and torquecontrol.This constant is automaticallyset during autotuning.0.32 to6.40*21.90 A*1 No Q Q Q Q 30EHE4-01 Motor 2 ratedcurrentSets the motor rated current in 1A units.These set values will become thereference values for motor pro-tection, torque limits and torquecontrol.This constant is automaticallyset during autotuning.0.32to 6.40*21.90 A*1 No A A A A 321HL1-01 Motor protec-tion selectionSets whether the motor overloadfunction is enabled or disabledat electric thermal overloadrelay.0: Disabled1: General-purpose motorprotection2: Inverter motor protection3: Vector motor protectionIn some applications when theInverter power supply is turnedoff, the thermal value is reset,so even if this constant is set to1, protection may not beeffective.When several motors are con-nected to one Inverter, set to 0and ensure that each motor isinstalled with a protectiondevice.0 to 3 1 No Q Q Q Q 480HL1-02Motor protec-tion time con-stantSets the electric thermal detec-tion time in seconds units.Usually setting is not necessary.The factory setting is 150%overload for one minute.When the motor's overloadresistance is known, also set theoverload resistance protectiontime for when the motor is hotstarted.0.1 to5.0 1.0 min No A A A A 481H
