Yaskawa D1000 – Regenerative Drive Unit
The Yaskawa D1000 is a high-performance Active Frontend unit designed for energy-efficient four-quadrant operation. Instead of being wasted as heat, braking energy is actively fed back into the supply grid and made available to other consumers — reducing energy costs and improving production efficiency through shorter machine cycles.
Clean grid feedback: The sinusoidal input current features a total harmonic distortion of less than 5%, with a power factor of approximately cos φ = 1. This protects generators, transformers, and cables while minimising interference with other system components.
Stable DC bus voltage: Even under fluctuating supply conditions, the DC bus voltage remains constant — ensuring consistent control quality for connected drives regardless of installation location.
Flexible configuration: The D1000 is suitable both as a 1:1 solution for single drives (elevators, escalators, presses) and for complex 1:n multi-drive systems combining frequency inverters, servo systems, and robots. In a shared bus configuration, braking energy is distributed directly within the common DC link.
Power range: 5 to 630 kW, for 200 V and 400 V networks, with an overload capacity of 150% for 60 seconds.
Complete package: The D1000 is supplied as a complete package including LCL filter module, input chokes, and optional EMC filter — a single order number, all components perfectly matched. Certified to UL, CE, and RoHS.
