b maXX 6500 compact monoblock servo converters 2.5–600 A, up to 315 kW

Country: · Model: b maXX 6500

The b maXX 6500 monoblock servo converter is rated for currents of 2.5–600 A and a power of up to 315 kW, with a maximum current of 5–800 A. In the cabinet it takes noticeably less space than ordinary drives, because size 4 of 75 kW is 71 % smaller than the market-average volume. It is used with DS2, DA1 and DST2 motors in casting machines, extruders, presses and shredders.

Description

The series from the b maXX 6000 generation has six sizes. The first, BM 6512–6516, is cooled by air only, has dimensions of 80 × 310 × 201 mm and currents of 2.5–10 A. Next come BM 6522–6526 for 7.5–22.5 A, BM 6532–6535 for 22.5–60 A (up to 120 A), BM 6543–6546 for 80–150 A, BM 6554–6556 for 210–300 A (up to 390 A) and BM 6563–6566 for 300–600 A with a peak of up to 800 A. The mains is 207–528 V AC, 50/60 Hz, the electronics are powered from an external 24 V DC, and the PWM frequency is 2/4/8 kHz. For size 4 the peak current is 20 % higher than for b maXX 5500, so a smaller size is often enough. The encoder can be a resolver, optical or digital; safety ranges from hardware STO/SS1 to integrated ISF functions. Programming is in ProDrive and ProMaster, with drivePLC support. Certification is CE and cUL, manual 5.22004.

How to choose

Focus on the motor rated current and the peak in the cycle. For 75 kW size 4 is used, with a maximum of up to 250 A, and for a rated current above 150 A one moves to size 5 or 6. The overload covers 1.3–3.6, so a less powerful model is often enough for short peaks. For long full-power load look at b maXX 5700 of 260, 450 and 720 A, and for multi-axis systems b maXX 6300 of 2 × 3…180 A.
