22.3–FUNCTIONS/MOTOROVERLOAD
The overload control function provides integrator logic to protect the motor against thermal overload. This protection
presents the characteristic I²t behaviour and is an emulation of the thermal relay of the motor controlled by the ADV
drive.

22.3.3 3204 Motorovldtime s FLOAT 30.0 10.0 300.0 ERWS FVS
Setting of the motor overload duration in seconds. It represents the moment in which the protection (“Motor Over-
load”) is enabled, if the motor current value is above the overload set in the Motorovldfactorparameter. This alarm
can be assigned to a programmable digital output (Motoroverloadtrip).
The trip time depends on the motor current value and is as follows:
Motor ovld factor
Rated current
Trip time [s]
Motor current [%]

22.3.4 3206 Motorservicefactor perc FLOAT 100.0 25.0 200.0 ERWS FVS
Setting of the motor service factor. This is the difference between the peak current and rated current. It is used to
calculate the thermal image of the motor.
