Product Description:

The HMS02.1N-F0070-A-07-NNNN is an axis inverter manufactured by Bosch Rexroth Indramat in the HMS Axis Inverters series. Installed in multi-axis drive cabinets, it converts DC bus energy into controlled three-phase output for servo or induction motors in automated machinery. By regulating motor torque and speed, the unit forms the electrical link between the machine controller and the driven axis. This makes it suitable for coordinated motion tasks in production equipment where several axes share one cabinet-based drive platform. Its cabinet-mounted format is intended for machines that centralize power electronics instead of mounting drives on the machine frame.

This model uses liquid cooling, so heat is removed by a coolant circuit instead of depending on panel airflow. That cooling method supports dense cabinet layouts because thermal load is carried away from the power section without requiring large air channels around the inverter. The enclosure has an IP20 protection class, which provides finger-safe access protection but is not sealed against water, making it appropriate for enclosed electrical cabinets. During operation, the power stage can supply a continuous 70 A to the motor windings from a shared DC link held at DC 700 V. A high DC bus level lets the inverter deliver the required motor voltage over a wide operating range. The inverter is design revision 1.

The control section does not include its own auxiliary supply, so external 24 V logic power is required for startup and diagnostics. The unit is line version 2. Separating logic power from the main DC bus allows the control electronics to be energized without turning on the full power stage. This keeps communication and status functions available during control-side checks while motor output remains inactive. It also fits systems that keep control power active during main power interruptions.
