Frequently Asked Questions

What are the implications of using the Bosch Rexroth Indramat HMV01.1R-W0120-A-07-NNNN in terms of DC‐bus energy recovery?

Because it’s a regenerative supply unit, braking or deceleration energy from connected drives can be fed back into the DC bus rather than wasted in resistors, improving overall energy efficiency and reducing heat loads in the system. It also means downstream components must tolerate regenerative currents and the DC‐bus must be sized for peak energy surges.

How does the high DC voltage (≈700V nominal) impact safety and insulation in wiring and enclosures?

Wiring insulation, creepage and clearance distances must conform to safety standards for high voltage; components must be rated to withstand worst-case surges. Enclosure design must prevent accidental contact, provide proper grounding, and satisfy regulatory requirements (e.g. UL/CE) for live parts above 50V.

How many on-off cycles per minute can the unit tolerate, and what effect does that have on reliability?

Max is “one cycle per minute”; exceeding that increases mechanical and electrical stress on internal components (contacts, capacitors, blower), leading to premature failure. For applications needing rapid cycling, external buffering or slower switching strategies are recommended.

What diagnostic and interface features are available for preventive maintenance?

The HMV01 series includes signals for “supply unit ready”, “power supply ok”, warnings such as overtemperature or braking resistor overload via contacts (X31), and optional interfaces like RS-232. Regular monitoring of these signals aids early detection of issues before full failures.

How will using this unit in a B2B industrial automation setup (with robotics or motion systems) translate into cost vs. benefit?

Regenerative energy means reduced energy consumption and lower cooling costs (less waste heat), which over time cuts operational cost especially in systems with frequent deceleration phases. However, the initial investment, wiring, infrastructure (e.g. proper mains, safety enclosures) and maintenance overhead must be factored in—break-even depends on duty cycle and energy cost.
