Product Description:

The HMS02.1N-W0028-A-07-NNNN axis inverter is produced by Bosch Rexroth Indramat for the HMS Axis Inverters series. It converts energy from a shared DC bus into closed-loop three-phase output for servo or induction motors in coordinated motion systems. Positioned between the supply module and the motor, the unit adjusts voltage and frequency so the higher-level controller can carry out precise position and speed commands on packaging lines, gantries, and assembly cells. Because the inverter regulates motor output in real time, it supports synchronized axis movement during acceleration, deceleration, and steady-speed operation. In multi-axis systems, this allows the controller to coordinate motor response across separate stations without relying on fixed-speed operation.

Thermal management uses internal air cooling with an integrated blower, which pulls air through the heat sink and discharges it into the control cabinet. On the power side, the inverter can deliver a continuous phase current of 28 A, so connected motor demand must remain within that limit during sustained operation. The module is tied to a common bus of DC 700 V, which sets the available motor voltage for the output stage. The housing has an IP20 rating, so the drive must be installed in an enclosure that prevents accidental contact and limits exposure to conductive dust. It comes without an integrated logic supply, so a separate 24 V source is required at the control terminals for control electronics and feedback circuits. Cabinet airflow should also account for the heat released by the blower because that warmed air remains inside the enclosure.

Configuration data identifies the unit as design version 1, indicating the first revision of this model. The power interface is line version 2, which matches the bus bar and connector arrangement used with second-generation supply units. The inverter is part of the HMS product type, so it follows the naming structure used for this drive platform. These version codes distinguish the mechanical and electrical arrangement used for the unit within the series. They also help place the inverter with the correct group of compatible system components in the same platform.
