Parameter Reference C-113AC30 series Variable Speed DriveMotor LoadParameters::Motor Control::Motor LoadMotor Protection, function of the motor type.The Motor Load parameters determines the allowed level of motor overload. This can be especially useful when operating with motors smaller thanthe drive rating.For an IM, an IxT protection is used and provides a current reduction if the max overload level is reached.The max overload level is calculated based on a 150% for 60s.For a PMAC motor, the motor load is calculated using the rated motor current and the thermal time constant (2 parameters of the PMAC motormodule). The Thermal time constant is used as the constant time of a simple 1 st order low pass filter.% Are all related to rated motor current.Parameter Name No. Path Default Range Units Writable100% Mot Current 0332 Parameters::Motor Control::Motor Load x.x 0.0 to 10000.0 NEVERMotor current in Amps rms corresponding to 100%Mot Inv Time Overload 0333 Parameters::Motor Control::Motor Load x. 0 to 500 % NEVEROnly available for IM motorOverload % of the motor inverse time protectionMot Inv Time Delay 0334 Parameters::Motor Control::Motor Load 6.000 to 60.000 s ALWAYSOnly available for IM motorOverload time of the motor inverse time protection from cold state
