Motor Poles
Motor Poles contains the number of motor poles. The drive
calculates this value during the Quick Motor Tune portion of the
start up routine.

Service Factor
Enter the minimum level of current that causes a motor overload
(I
2
T) trip under continuous operation. Current levels below this
value never result in an overload trip. For example, a service
factor of 1.15 implies continuous operation up to 115% of
nameplate motor current.
