b maXX 5000 / 5100 DC link power supply units 5–200 kW, including with regeneration to the mains

Country: · Model: b maXX 5000 / 5100

b maXX 5000 and 5100 are DC link power supply units for a modular servo drive system. The 5000 series gives a 5–200 kW link and 7.5–300 kW peak, while the 5100 adds regeneration of braking energy to the mains at 36–200 kW. From one unit, single- and double-axis b maXX 5300 and 6300 modules are fed through a common link.

Description

The 5000 series is a system rectifier in three frame sizes. The range includes the BM 5030 (5/7.5 kW), BM 5031 (10/15 kW), BM 5032 (18/27 kW), BM 5043 (36/54 kW), BM 5044 (70 kW), BM 5074 (150/300 kW, overload 2) and BM 5075 (200/300 kW). In the 5100 series, braking energy is not turned into heat in a braking resistor but is returned to the mains as sinusoidal current. The range BM 5173 (36/54 kW), BM 5174 (64/96 kW), BM 5192 (150/300 kW) and BM 5193 (200/300 kW) allows overload for up to 120 s, with a nominal DC link voltage of 640 V. Energy costs account for more than 90 % of the life-cycle cost of a drive, so regeneration noticeably reduces total costs.

How to choose

The modules are mounted directly next to the power supply unit and connected with the drive connect system, so an individual module can be removed or added without taking the whole system apart, and the number of axes depends on the link power. Mains voltage is 207–528 V AC (nominal 400 V), 50/60 Hz, and the electronics are supplied from an external 24 V DC. Cooling is by air, through a plate (cold plate) or by water using push-through technology. The central STO module switches off all motors in the power supply unit and meets SIL 2 per IEC 61508 or PLd cat. 3 per EN ISO 13849-1. The BM5-CAP capacitance module stores braking energy for the next acceleration, and the units are certified to CE and cUL.
