Performance (Torque
Capabilities)
PowerFlex™ 7000 drives have been tested on a dynamometer to verify
performance under locked rotor, accelerating, and low speed-high torque
conditions. Table 22
shows the PowerFlex 7000 drive torque capabilities as a
percent of motor rated torque, independent of the momentary overload
conditions of the drive.
