Description Two parameters in the S4 work together to congure how the motor timed overload operates:
DRV 01 - Nom Mtr Amps and AFN 22 - TOL Select.
DRV 01 (Nom Mtr Amps) should be congured 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.
