Product Description:

The HMS01.1N-W0020-A-07-NNNN-AA is an axis inverter produced by Bosch Rexroth Indramat and assigned to the HMS Axis Inverters series. It converts regulated DC bus energy from a central supply unit into controlled three-phase output for servo or induction motors used in automated machinery. Within a multi-axis system, the inverter executes torque, speed, and position commands from the motion controller as the actuator side of closed-loop automation. This arrangement allows a shared supply architecture while each inverter regulates the output delivered to its own motor.

This unit removes internally generated heat through internal air cooling with an integrated blower, so the cabinet only needs adequate ventilation paths instead of an external heat exchanger. Because cooling air is handled inside the unit, the surrounding panel should leave clear airflow paths around the inverter. The power stage uses a nominal bus voltage of DC 700 V, which matches the high-energy links used in modular drive systems and supports fast current response on dynamic axes. The enclosure has an IP20 rating, so it must be installed inside a protected cabinet and is guarded against contact with larger solid objects. The converter can deliver up to 20 A of phase current, making it suitable for low-to-medium power servo motors and induction motors. The unit is marked as Design Version 1, indicating the first design revision of this inverter format.

The control section has no internal power supply, so low-voltage logic power must be provided from an external source. The inverter is identified as Line Version 1, indicating the first line release of this platform. Separating the control supply from the main power stage supports modular system layouts in which several axes share a central DC source. It also keeps logic power distribution separate from the inverter power section in multi-axis cabinet installations.
