22.4 – 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.
When the function is enabled, the value reached by the integrator is stored each time the drive is switched off. The
saved value is restored each time the drive is switched on.
