Description

There are AC/AC configurations with 6-, 12- and 18-pulse rectifiers, DC/AC with a common bus, and regenerative ones with an AFE active rectifier. The drives are UL/CSA certified, and the STO safe torque off function meets PL e / SIL3 under Machinery Directive 2006/42/EC. The AD5000 works with induction motors and permanent magnet synchronous motors. Control is V/f, sensorless vector or field-oriented with an encoder or resolver, efficiency up to 98 %, output frequency 0.1–200 Hz, PWM frequency 1.5–8 kHz. The degree of protection is IP20 for frame sizes I–VI and IP00 for VII–VIII, and the width is only 11 inches. Ethernet protocols and legacy fieldbuses are supported.

How to choose

First determine the voltage class, 380–480 V or 500/525–690 V AC, or 650 and 975 V DC. The AD5000 gives 18.5–450 kW per drive (up to 3.6 MW in parallel) and 200–500 kW per drive up to 4 MW with up to 8 units in parallel, and the AFE reaches 5.3 MVA. The Accel500 is intended for general industrial and high-performance tasks, including common-bus inverters (frame sizes FR4–FR13) and application software for cranes and winders. The AD9000 serves as a power module for medium-voltage, marine and multipurpose applications, and PCS for BESS and solar plants are built on such modules.
