6 -34Related Constants* These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.Setting PrecautionsWhen this function is enabled, if the main circuit voltage rises, the regenerative torque limit will decrease to avalue less than its set value and so the motor will not rotate at the speed specified by the speed reference.Therefore, in applications where it is necessary to rotate the motor at the speed specified by the speed refer-ence, disable this function and use a converter, a dynamic braking resistor, or a power regenerative unit to sup-press rises in the main circuit voltage.Con-stantNumberName Description SettingRangeFactorySettingChangeduringOpera-tionControl Methods MEMOBUSRegis-terV/fV/fwithPGOpenLoopVec-torFluxVec-torL3-11Overvoltageinhibit selec-tion0: Disabled1: EnabledUsed to enable or disable thefunction for inhibiting main cir-cuit overvoltages by reducingthe regenerative torque limitaccording to the main circuitovervoltage level.If this function is enabled, whenthe main circuit voltage rises,operation will be performedwith the regenerative torque lessthan the set value.0 or 1 0 No No No A A 4C7HL3-12Overvoltageinhibit volt-age levelSets the main circuit voltagelevel for which the regenerativetorque limit is restricted to 0.Usually, there is no need tochange this setting.If main circuit overvoltagesoccur even with the overvoltageinhibit function enabled, reducethis setting.350 to390 * 380V * No No No A A 4C8H
