6 -56 Detecting Motor TorqueIf an excessive load is placed on the machinery (overtorque) or the load is suddenly lightened (undertorque),you can output an alarm signal to multi-function output terminal M1-M2, P1-PC, or P2-PC.To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection NO/NC) in one of the following constants: H2-01 to H2-03 (multi-function output terminals M1-M2, P1-PC, andP2-PC function selection).The overtorque/undertorque detection level is the current level (Inverter rated output current 100%) in V/fcontrol, and the motor torque (motor rated torque 100%) in vector control.Related ConstantsCon-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torL6-01Torque detec-tion selection10: Overtorque/undertorquedetection disabled.1: Overtorque detection onlywith speed agreement;operation continues afterovertorque (warning).2: Overtorque detectedcontinuously duringoperation; operationcontinues after overtorque(warning).3: Overtorque detection onlywith speed agreement;output stopped upondetection (protectedoperation).4: Overtorque detectedcontinuously duringoperation; output stoppedupon detection (protectedoperation).5: Undertorque detection onlywith speed agreement;operation continues afterovertorque (warning).6: Undertorque detectedcontinuously duringoperation; operationcontinues after overtorque(warning).7: Undertorque detection onlywith speed agreement;output stopped upondetection (protectedoperation).8: Undertorque detectedcontinuously duringoperation; output stoppedupon detection (protectedoperation).0 to 8 0 No A A A A 4A1HL6-02 Torque detec-tion level 1Open loop vector control: Motorrated torque is set as 100%.V/f control: Inverter rated cur-rent is set as 100%.0 to 300 150% No A A A A 4A2H
