Product Description:

The HMS01.1N-W0210-A-07-NNNN is an axis inverter module produced by Bosch Rexroth Indramat. As part of the HMS Axis Inverters series, it operates in a modular drive system with a central power supply. The unit converts DC link energy into controlled three-phase output for servo motors, positioning stages, and other motion axes used in automated machinery. In a multi-axis machine, it serves as the power stage between the shared DC link and the connected motor, supporting controlled motion for positioning and synchronized axis movement.

The inverter uses internal air cooling with an integrated blower, so the built-in fan moves cabinet air across the heat sink and no external ventilation duct is needed. Its nominal DC bus is rated at DC 700 V, allowing the module to draw regulated energy from a common supply and deliver it to the motor phases through pulse-width modulation. The rated maximum output current is 210 A, which supports high-torque demand on large servo axes without continuous derating. The front panel uses finger-safe terminals and bus bars within an IP20 enclosure, which helps protect against contact with larger solid objects while still allowing cabinet airflow. Because the cooling path is internal, cabinet airflow can be directed through the inverter area without separate duct hardware.

The module has no internal logic supply, so it requires 24 V control power from an external source during startup and fieldbus communication. Separating the control supply from the power stage allows communication and startup functions to remain available before the main drive section is energized. The product type is HMS, and the unit is design version 1. It follows the shared footprint and wiring pattern used across the series, which helps maintain consistent cabinet layouts in multi-axis systems.
