C-44 Parameter ReferenceAC30 series Variable Speed DriveCurrent LimitParameters::Motor Control::Current LimitDesigned for all Motor Control ModesThis function allows you to set the maximum level of motor rated current (as a % of the user-set Motor Current) which is allowed to flow beforecurrent limit action occurs. If the measured motor current exceeds the current limit value with a motoring load, the motor speed is reduced to controlthe excess load. If the measured motor current exceeds the current limit value with a regenerating load, the motor speed is increased up to amaximum of 100% Speed in RPM (Scale Setpoint).The maximum value of current limit for a particular motor is limited by the AC30V current rating.If a motor of larger rating than the AC30V is connected, then the current limit max value is limited by the AC30V current rating.If a motor of lower rating than the AC30V is connected, then the current limit max value is limited to 300% (if compatible with the AC30V currentrating) for an induction motor (IM) and to the ratio PMAC Max Current to PMAC Rated Current for a PMAC motor.% are always expressed as % of the user set Motor Current (rated current of PMAC or IM Motor).Parameter Name No. Path Default Range Units WritableCurrent Limit 0305 Setup::Motor Control ::Control and TypeParameters::Motor Control::Current Limit 150.0 0.0 to 600.0 % ALWAYSThis parameter sets the level of motor current, as a % of Motor Current (refer to the relevant MOTOR definition , PMAC or IMfunction) at which the Drive begins to take current limit action.Regen Limit Enable 0307 Parameters::Motor Control::Current Limit TRUE ALWAYSThis parameter enables or disables regenerative current limit action.Note that this parameter only works in open-loop VOLTS / Hz motor control mode.Functional DescriptionInternal limit : output of the Stack Inv Time module + reductionas a function of electrical low speed ( < 3Hz ) and as functionof heatsink temperatureminimumCurrent limitInternal limitCurrent Limit Output
