        Overview Manuals Energy Flow High-Current Wiring Cycle Validation Application
        • Keep the 300 A maximum-current capability distinct from the 150.1 A continuous rating at 4 kHz
        • Use 108 A as the continuous-output limit when the selected switching frequency is 8 kHz
        • Check acceleration demand, DC-bus voltage drop and high-current cabling together during replacement validation

        HMS01.1N-W0300-A-07-NNNN is a Bosch Rexroth IndraDrive M HMS01 single-axis inverter power section designed for high peak-current duty.

        Its 254–750 V DC-bus input supplies up to 300 A maximum output, with continuous current limited to 150.1 A at 4 kHz and 108 A at 8 kHz.

        During acceptance testing, monitor DC-bus stability and motor current through acceleration, verify 357 m³/h cooling airflow, and confirm the control section, firmware and commissioned current limits.

        Description
        HMS01.1N-W0300-A-07-NNNN is a Bosch Rexroth high-current single-axis inverter power section in the IndraDrive M HMS01 family.

        Bosch Rexroth HMS01.1N-W0300-A-07-NNNN is an air-cooled IP20 IndraDrive M HMS01 inverter power section for one axis, using a 254–750 V DC bus and delivering three-phase motor output. The complete code identifies the IndraDrive M HMS01 power section, air cooling, current class and A-07-NNNN design. It is not a complete drive controller by itself: the control section, firmware and required system components are separate identities.

        Before installation or replacement, confirm the complete HMS01.1N-W0300-A-07-NNNN type plate, separate control section, power and motor connections, cooling arrangement, firmware and commissioned parameters.

        Technical notes
        HMS01.1N-W0300-A-07-NNNN is an inverter power section, not a complete drive controller; the control section and firmware remain separate. Match the full type plate, DC-bus supply, motor data, cooling and commissioned parameters before replacement.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why is HMS01.1N-W0300-A-07-NNNN not a drop-in substitute for W0210 despite the same dimensions?
        Its input, output, peak-current and thermal curves differ. Recheck the DC-bus supply, protection, motor duty, parameters and cable sizing rather than relying on the shared enclosure.
        Can HMS01.1N-W0300-A-07-NNNN absorb regenerated energy by itself?
        It is an inverter power section, not the system energy sink. Regeneration must be handled by the documented supply, braking or common-bus architecture sized for the machine cycle.
        Why can an HMS01.1N-W0300-A-07-NNNN axis exceed its thermal limit even when the motion profile never reaches 300 A?
        The 300 A value is not a continuous-duty allowance. Thermal loading depends on RMS current, acceleration frequency, dwell time, switching frequency, ambient conditions and cooling airflow. Evaluate the complete machine cycle rather than its single highest current value.
        Why can HMS01.1N-W0300-A-07-NNNN produce inaccurate torque after a motor or feedback-device replacement?
        The control section may still contain motor, encoder, polarity or torque-constant data from the previous hardware. Verify the exact motor and feedback identity, cable connections, commutation data, current scaling and approved parameter set before load operation.
        What control-section information is required with HMS01.1N-W0300-A-07-NNNN?
        Record the exact control-section type, firmware, safety option, motor encoder interface and parameter archive. The power-section code alone does not define the finished drive.
        How should the 24 V control supply be sized for HMS01.1N-W0300-A-07-NNNN?
        Include the documented power-section control demand together with the control section, motor brake, relays, I/O and voltage drop in the wiring. Verify both continuous and transient demand at the drive terminals rather than sizing the supply from the nominal power-section value alone.
        Can the current limit of HMS01.1N-W0300-A-07-NNNN be raised simply to improve acceleration?
        No. The permitted limit must protect the motor, motor cable, coupling and driven machine and remain within the approved drive duty. Investigate load inertia, acceleration time, DC-bus capacity and mechanical resistance before changing current or torque limits.
