When two-speed motor functionality is used, these settings allow the selection of proper parameters for the thermal model
when motor is switched to the second speed. There is one thermal model in the M60, and it has inputs for overload condi-
tions from calculations at both speeds. As such, the accumulated thermal capacity is calculated from overload contributions
at each speed.
Refer to the Thermal model sub-section for details on settings for thermal model at the second motor speed.
