D1000 Series

Regenerative Converter Unit

The D1000 regenerative converter unit complements Yaskawa’s product range with a low-harmonic active front-end solution. It is suitable for both standalone regenerative drive systems and AC drive, servo axis, or robotic applications. Instead of dissipating braking energy as heat, it feeds it back to the power grid.

4Q Operation for Energy Savings

Excess braking energy is reused by other loads on the same power network, boosting energy efficiency. The system supports 100% duty cycle for full braking power, reducing machine cycle time and improving productivity.

User-Friendly Package

Delivered as a complete, single-part-number package, D1000 simplifies procurement and guarantees full component compatibility.

Compliant with Global Standards

Fully compliant with major international standards such as UL, CE, and RoHS.

R1000 Series

Regenerative Unit

The R1000 is an intelligent and efficient alternative to dynamic braking for single or multi-axis drive systems with high regenerative activity. Instead of wasting excess braking energy as heat, it feeds it back to the grid—reducing energy consumption.

Smart System Design

R1000 is sized based on braking power, allowing for smaller dimensions than the associated drive. This minimizes footprint, lowers cost, and maximizes efficiency.

Cool Operation

By eliminating the need for braking resistors, R1000 saves space and reduces fire risks. Less heat is generated, lowering ventilation demand and maintenance requirements.

Cost-Effective

In demanding applications like cranes, escalators, and elevators, the R1000 offers significant benefits. Smaller installation size and lower thermal output reduce installation costs, while regenerated energy cuts operating costs—allowing for a rapid return on investment.
