Product Description:
The HMS01.1N-020-SE axis inverter is produced by Bosch Rexroth Indramat and belongs to the HMS Axis Inverters series. As a single-axis power module, it converts DC bus energy into regulated three-phase output for servo or induction motors, forming the power stage of a drive system in industrial automation. The module is designed for cabinet installation where a compact profile and network-synchronized motion are required. In coordinated systems, it responds to drive commands quickly so torque and speed can be adjusted during positioning, conveying, and indexing tasks. This makes it suitable for packaging equipment, transfer systems, and other automated machinery that relies on repeatable axis response.
Communication is handled over SERCOS, providing deterministic timing between the inverter, the central controller, and other drives on the ring. Logic circuits receive isolated power from a 24 VDC supply, permitting parameter retention and controlled shutdown when mains are removed. During normal duty, the unit delivers a continuous phase current of 12.1 A, with thermal stability maintained by internally guided airflow across its heat sink. The housing measures 440 mm in height and only 50 mm in width, so multiple axes can be lined up without exceeding typical cabinet space. A rated input draw of 14.0 A matches circuit-breaker sizing, and an RS232 service port supports direct setup access and diagnostic capture.
The drive’s protection class is IP20, so it must be mounted behind a closed panel to reduce accidental contact and limit the entry of larger particles. An installation mass of 5.27 kg keeps handling manageable during cabinet mounting while still providing enough thermal mass for stable operation. For brief acceleration commands, it can supply up to 20 A of motor current, after which it returns to its steady-state range. Internal switching losses generate 165 W of heat that the cabinet ventilation must remove. When paired with machinery that needs as much as 5.5 kW of mechanical power, the inverter remains within its intended electrical operating range even though it does not include an integrated DC bus supply.
