* The rated currents in given ambient temperatures are achieved only when the switching
frequency is equal to or less than the factory default. Thermal management might reduce the
switching frequency.
** System software version NXP00002V186 (or newer) must be used for the motor thermal memory
and memory retention functionality to conform to UL 508C requirements. If an older system
software version is used, motor overtemperature protection is required at installation to comply
with UL requirements.
