Description Two parameters in the S4 work together to congure how the motor timed overload operates:
DRV 01 - Nom Mtr Amps and AFN 22 - TOL Select.
DRV 01 (Nom Mtr Amps) should be congured to the value on the nameplate of the motor. This value is
used in calculating the percentage of load on the motor.
AFN 22 - TOL Select determines the graph of Trip (Fault) time vs. Percent Current that is used by the
Motor TOL functionality. This protective feature is speed-dependent to handle standard induction motors
whose cooling is limited by the shaft-mounted fan. Blower cooled motors and most inverter duty motors
do not have this limitation.
