The Bosch Rexroth IndraDrive Power Supply Unit, MPN R911296724 (HMV01.1E-W0030), is a modular converter element that provides a 30 kW output and nominal 700 V DC bus voltage for coupled inverters. The unit features a Smart Energy Mode to reduce energy losses in the mains connection line and limit peak loads. Design includes internal air cooling via an integrated blower, a single-line configuration, and a metallic IP20-protected housing. It supports HMS01 and HMD01 devices, requires a 24 V ±5% control voltage, has a maximum inrush current of 5 A, and consumes 55 W at control voltage input. The unit measures 350 mm by 262 mm by 440 mm, weighs 13.5 kg, and contains 2 × 470 nF capacitance against housing.

Frequently Asked Questions

What is the significance of the 2 × 470 nF capacitance to the chassis in this unit?

These capacitors help suppress electromagnetic interference (EMI) by filtering high-frequency noise to the housing/ground, reducing conducted emissions on the DC bus. In practice they ensure compliance with EMC standards and protect downstream drives from voltage spikes.

How does the 24 V control voltage input ±5% affect control reliability?

A tolerance margin of ±5% means fluctuations (22.8-25.2 V) are accepted without triggering control faults, ensuring stable operation even with minor drops or surges in the control supply. If the voltage falls outside this band, the device may issue error messages or shut down non-safely.

What are the DC bus voltage and its implications for compatible drives when using the HMV01.1E-W0030-A-07-FCN1?

The nominal DC bus voltage is ~700 VDC, which requires drives rated for that voltage; mismatched voltage ratings can cause overvoltage damage or underperformance. Also, high DC bus voltage means better performance for high speed/torque motors but imposes stricter insulation and safety requirements.

How does maximum inrush current (5 A at 24 V control voltage) affect startup sequencing and protection?

The inrush to the control circuits must be considered when sizing fuses or protection devices — if many similar units start simultaneously, combined inrush can exceed supply limits. Soft-start or staged powering of control voltages helps avoid nuisance tripping.

What are the effects of the mains choke inductance specification in HMV01.1E-W0030 (≈ 400 µH) on performance during dynamic loads?

The mains choke limits AC ripple and helps stabilize the bus during load changes; with ~400 µH, this unit smooths current peaks and limits voltage drop under sudden power demand, improving drive stability and reducing mains stress. Lower inductance could yield faster response but more ripple; higher could slow response and increase size/weight.
