RS-232, Macro, and USB connectivity are available. Both Turbo UMAC and QMAC work with virtually any stepper or servo motor and amplifier . Ability to use standard synchronous motors brings out their advantages of efficiency, reliability, and lower initial cost. Existing synchronous motors can also be retrofitted with these newer MV drives, says Robicon . The scarcity seems to be in qualified combinations of motors and controls.
Low demand is also a contributor.
Not to despair, the product you seek is available. Moeller's Compact Drive comes in 0.55-11 kW sizes , with IEC motors, and was on exhibit at Hannover Fair in Germany. A NEMA-style motor should be a possibility, given some level of user demand. Here is just a sampling of the innovations. The white paper contains comprehensive technical analysis and cost-savings information about intelligent MCCs.
