Product Description:

The HMS02.1N-F0150-A-07-NNNN is an axis inverter manufactured by Bosch Rexroth Indramat for the HMS Axis Inverters series. It is used in a modular drive system that supplies controlled DC power to servo and spindle amplifiers in multi-axis industrial equipment. By regulating motor current and processing feedback signals, the unit helps connected axes follow commanded speed, torque, and position values from the higher-level controller. Its position between the central supply module and the motor-connected amplifiers supports coordinated motion across automated production systems.

This inverter uses liquid cooling, which transfers heat to an external coolant loop and helps keep the electronics at a stable operating temperature inside the cabinet. Its rated maximum output is 150 A, so the unit can supply high continuous armature current for demanding axes that require strong acceleration and steady torque delivery. The shared DC link operates at a nominal value of DC 700 V, providing the energy source for connected drive modules within the system. The enclosure is rated IP20, which protects against accidental contact with live parts, but the inverter should still be installed in a closed control cabinet where dust or fluids may be present. Using an external coolant circuit also helps move heat away from the cabinet interior instead of releasing it directly into the surrounding air.

The unit is design version 1 and uses line version 2, which identify its release and line coding within the platform. It comes without an internal power supply, so a separate 24 V control voltage must be provided for the control electronics. This arrangement allows the control section to be supplied independently from the main DC bus when the cabinet layout is built that way. It also supports use with matching power supplies and bus modules that follow the same modular system structure.
