Description
The power units are made in seven frame sizes and five cooling variants. The range runs from the BM 4412 (2.5 A, max. 5 A, 1.1 kW motor) through the BM 4434 (45/90 A, 20 kW) and BM 4446 (150/200 A, 75 kW) to the BM 4473 (615/780 A, 315 kW motor, 520 × 600 × 340 mm). The overload factor is 2.0 for small frame sizes and 1.3 for large ones. Mains is 207–528 V AC (nominal 400 V), 50/60 Hz, the nominal DC link voltage is 540 V, the PWM frequency is 2/4/8 kHz, and the output voltage is up to 95 % of the mains voltage. The electronics are supplied from an external 24 V DC with diagnostics preserved, and the fans from 24 V DC (frame sizes 1–3) or 230 V AC (4–7).
How to choose
The main difference is modularity, with up to eleven slots for exchangeable modules. More than 30 function and option modules are available, including 24 V digital inputs and outputs, analog ±10 V and 4–20 mA with 8–16 bit resolution, encoder interfaces (SinCos Hiperface, EnDat 2.1/2.2, resolver, 5 V incremental, SSI) and a parameter memory module for 8 sets and 16 positioning profiles, which makes it possible to replace a drive without knowing the software. The standard bus is EtherCAT, and EtherNet/IP, CANopen and others are supported. The b maXX-drivePLC module executes 1000 lines of STL in 100 µs and can offload or replace the control PLC. Certification CE, CSA and UL.
