2.2.8 Speed Range:

Operator's Speed Adjustment............................................................................... 0 to rated speed

Specification Speed Range ........................................100:1 based on top speed and tachometer

2.2.9 Drive Efficiency:

Drive Only........................................................................................98.6% (rated load and speed)

Drive and Motor............................................................................................................85% typical

2.2.10 Displacement Power Factor, Power Loss P

and Output Current:

Power Factor: 88% typical (rated load & speed, decreasing linearly with speed)

Typical percent speed depends on motor operating speed and motor frame size.

Power Consumption at no load: see P

in Table 2-3.
