Bosch Rexroth HMS01.1N-W0054-A-07-NNNN Single-Axis Inverter
A DC-bus-fed HMS01 inverter with internal air cooling for one controlled motor axis.
Key Information
HMS01.1N-W0054-A-07-NNNN is a Bosch Rexroth IndraDrive M single-axis inverter, material number R911295325. It is supplied from the DC bus of a compatible IndraDrive supply unit and generates the controlled motor output for one axis.
The complete ordering string identifies line 01, design 1, no integrated power supply, internal air cooling, the W0054 current class, IP20 construction, a 700 V nominal DC bus and no additional design option. The complete suffix must be retained during replacement.
Functions
- Converts the shared DC-bus energy into a variable motor output for one servo axis.
- Operates as a modular drive-axis component together with the compatible supply unit, control section and motor feedback system.
- Uses an integrated blower to support cabinet-mounted internal air cooling.

Installation
- Match the complete type plate, material number, control section and firmware package before ordering.
- Verify the upstream IndraDrive supply unit, DC-bus architecture and 24 V control supply before installation.
- Maintain the manufacturer-defined mounting orientation, ventilation clearances and cabinet cooling path.
- After replacement, restore the controlled parameters and test enable, feedback, braking and axis motion under the approved machine procedure.
Lifecycle
- Record the inverter material number, control-section identity and firmware together in the asset file.
- Keep the integrated blower and heatsink airflow path clean during planned maintenance.
- Plan legacy-system support at complete IndraDrive axis level rather than treating the power section as a universal substitute.
FAQ
Does HMS01.1N-W0054-A-07-NNNN contain its own mains supply?
No. HMS01.1N-W0054-A-07-NNNN is a DC-bus-fed single-axis inverter and requires a compatible IndraDrive supply arrangement.
What should be matched before replacing HMS01.1N-W0054-A-07-NNNN?
Confirm R911295325, the complete type code, control section, firmware, option modules, motor feedback and DC-bus design.
Can another W0054 inverter replace HMS01.1N-W0054-A-07-NNNN?
Only after the complete ordering code and material number are proven equivalent; matching the W0054 current class alone is insufficient.
What cooling provision does HMS01.1N-W0054-A-07-NNNN require?
The inverter uses internal air cooling with an integrated blower, so mounting clearances and cabinet airflow must remain unobstructed.
What evidence is useful for an HMS01.1N-W0054-A-07-NNNN enquiry?
Provide the power-section and control-section labels, firmware display, cabinet position, connected supply-unit reference and fault history.
