Yaskawa U1000 matrix drive, 5–800 HP, regenerative, low harmonics, IEEE 519

The Yaskawa U1000 is an all-in-one matrix drive for applications where low harmonics and full regeneration of energy to the mains are important. It needs no separate active front end or braking resistor and helps to meet IEEE 519 requirements.

Eco-Mode reduces THD almost to the level of direct-on-line starting; the power factor is close to unity at full load. Built-in input fuses, SCCR 100 kA, high efficiency compared to other low-harmonic topologies, MTBF 28 years.

Output 0–400 Hz, overload 120 % 60 s (ND) and 150 % 60 s (HD). Control of induction and PM motors, closed and open loop vector, continuous auto-tuning, high-frequency injection. Modbus RTU as standard, options for major industrial networks, STO SIL CL3 / PLe / category 3.

Key features:

• Regeneration without external AFE or braking resistors
• Low harmonics — easier approval by the utility
• More compact than a drive + filter + regenerative unit combination
• One unit for IM and PM motors
