Description
Product Overview
HMV01.1R-W0018-A-07-NNNN (R911297460) is a regenerative mains supply unit for the Bosch Rexroth IndraDrive M modular servo drive platform. It converts 3-phase AC mains into a common 700 VDC shared DC bus for multiple HMS01 single-axis servo inverters. The “R” suffix means regenerative capability: braking energy from servo axes can be fed back into the grid instead of dissipating on brake resistors, saving energy. It forms the central power backbone of multi-axis motion control systems, widely used for machine tools, metallurgical lines and heavy automation equipment.

Key Features
- Regenerative Energy Feedback: Returns motor braking kinetic energy back to the AC power grid, reduces heat loss and eliminates large external braking resistors.
- Shared Common DC Bus: One HMV supply feeds multiple HMS01 axis inverters; axes can exchange energy directly across DC bus for coordinated motion.
- Integrated Protection Functions: Overvoltage, undervoltage, overcurrent, over-temperature, mains phase loss and DC bus short-circuit protection, fault codes stored for troubleshooting.
- Built-in Diagnostics & Status Display: Front panel LED indicators for power, operating state and fault alarms; communicates drive status to higher-level controller.
- Modular Slide-in Design: Hot-swappable after full DC bus discharge and lockout/tagout, convenient for maintenance and spare replacement.
- High Stability DC Bus Regulation: Maintains stable 700 VDC under dynamic load fluctuations for high-precision servo motion.
- Compact Cabinet Installation: Optimized for cabinet layout, works seamlessly with IndraMotion MLC/MTX motion control platforms.
Applications
- Heavy-duty CNC machine tools, metal stamping and forming machines
- Metallurgical rolling mills and continuous processing production lines
- Printing, paper and packaging high-speed multi-axis lines
- Material handling, crane and lifting servo motion control
- Automated assembly lines and robotic multi-axis systems
Installation & Maintenance Notes
- Execute strict lockout-tagout procedure. DC bus capacitors retain dangerous high voltage long after AC power is cut; mandatory discharge before opening unit.
- Use ESD protection during handling and replacement.
- Maintain adequate cabinet ventilation, regularly clean cooling fan and filter to prevent overheating.
- Verify 3-phase mains wiring, DC bus connection and grounding before power-on.
- Match firmware versions when replacing spare HMV unit; verify communication with connected HMS axis inverters.
- Periodically inspect blower operation, terminal tightness and dust accumulation during scheduled maintenance.
- Confirm regenerative power capacity matches total peak power demand of all connected servo axes.
FAQ
Q: What does the “R” in HMV01.1R mean? A: “R” = Regenerative type, can feed braking energy back to grid. The “E” version is non-regenerative (diode rectifier).
Q: What is the difference between HMV01.1R-W0018 and HMS01.1N-W0110? A: HMV01 is the central rectifier power supply unit, creates shared DC bus. HMS01 is single-axis inverter that drives individual servo motors; multiple HMS inverters connect to one HMV supply.
