Speed Range:
Operator's Speed Adjustment ............................................................................. 0 to rated speed
Specification Speed Range ................................100:1 based on Gear In Speed and tachometer
Drive Efficiency:
Drive Only ...................................................................................... 98.6% (rated load and speed)
Drive and Motor ..........................................................................................................85% typical
Displacement Power Factor, Power Loss Pv 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
