Product Description:
The HMS01.1N-W0036-A-07-NNNN-AA axis inverter belongs to the HMS Axis Inverters series from Bosch Rexroth Indramat. It converts the constant energy of a DC bus into controlled three-phase power for synchronous or induction motors, allowing closed-loop speed and torque control in industrial automation lines. Through standardized power connectors and signal interfaces, the unit can be stacked with matching modules, which supports compact multi-axis assemblies and coordinated motion commands from higher-level PLCs. This arrangement helps keep cabinet layouts compact and lets adjacent axes share a common platform for power distribution and signal routing.
Its continuous output is limited to a rated maximum current of 36 A, so motor and cable selection must stay within that value to avoid thermal overload. The inverter draws energy from a shared bus stabilized at DC 700 V, which provides a high intermediate voltage that can help reduce conductor size and switching losses. Heat generated by the IGBT stage is removed by internal air cooling with an integrated blower, so cabinet air is circulated across the heat sink without the need for an external fan assembly. The unit has an IP20 protection class and must be installed inside a closed control cabinet. Because the cooling air is drawn from the cabinet interior, surrounding equipment must allow unobstructed airflow across the module surfaces. The product is Design Version 1, so its mechanical dimensions and connector assignments match the earliest HMS release.
The control electronics obtain auxiliary power externally because the unit is not equipped with an internal 24 V source, which allows a centralized low-voltage supply to serve multiple axes. Using an external control supply also separates low-voltage support power from the main DC bus, so the control section can be integrated with centralized cabinet power distribution. The inverter uses Line Version 1, and drive tools reference that code when loading parameter sets. The device is identified as HMS in diagnostics and engineering records, which helps distinguish it from other product types in a multi-axis cabinet.
