Product Description:
The HMS01.1N-W0070 axis inverter is manufactured by Bosch Rexroth Indramat as part of the HMS Axis Inverters series. Within an automation cell, it acts as the intermediary between the line supply and a servo or induction motor, generating a variable-frequency, variable-voltage output that lets the machine controller dictate precise speed and torque profiles. This function makes the unit a core component in packaging lines, metal-cutting centers, and handling systems where tightly coordinated multi-axis motion is required. It is suited for systems that need repeatable acceleration, controlled deceleration, and stable speed regulation during changing process loads. This supports coordinated motion in machines with frequent starts and stops.
For continuous duty the power stage can supply 42.4 A, giving enough margin for motors that draw high RMS current under load. When rapid accelerations are needed, the drive permits a peak output of 70 A, helping the axis overcome inertial spikes without shutting down. Line conductors feed the converter with a rated input of 49.0 A, and this value is useful when selecting upstream wiring and protection. Heat generated by the IGBT switching devices is removed through internal air cooling with an integrated blower, so cabinet layouts do not require external ducting. The loss budget lists a steady-state dissipation of 485 W, which helps determine enclosure airflow and thermal spacing between adjacent modules.
The control section is powered from a separate 24 V DC source that keeps logic active during line power interruptions and supports fieldbus communication. Dynamic response includes a load time constant of 50 ms, showing that motor current can settle quickly after a command change. For panel layout, the housing stands 440 mm tall and uses a slim front profile, which helps fit multiple axes in a compact cabinet. Installation weight is kept to 7.9 kg, reducing the load placed on mounting hardware during installation. The narrow mechanical format also leaves more room for cable routing and airflow around neighboring drive modules.
