Product Description:
The HMS01.1N-W0020 is an axis inverter manufactured by Bosch Rexroth Indramat for the HMS Axis Inverters series. It functions as a power conversion stage that links a 400 V cabinet supply to individual servo or induction motors, enabling precise current and voltage modulation under drive controller commands. By handling commutation, protection, and diagnostic tasks inside a narrow housing, the inverter supports multi-axis packaging machines, gantries, and process lines that need coordinated motion while keeping panel space usage low and cabinet layouts easier to organize.
This model delivers a continuous output of 12.1 A and is energized by a control circuit that expects 24 V DC. Heat produced by the switching elements is removed by internal air cooling with an integrated blower, so external ducting is unnecessary. The power stage accepts a 3 AC 400 V supply and can provide up to 20 A during peak loading. A carrier frequency of 4 kHz sets how often the IGBTs switch each second, balancing dynamic response and switching losses. Standby demand remains modest because the electronics draw 0.4 A and 10 W when the motor connection and brake are idle. Because the unit does not include an internal power supply, it relies on external 24 V control wiring for logic, brake relay, and blower operation.
The housing weighs 5.3 kg, measures 309 mm deep, and is only 50 mm wide, allowing high-density stacking on rail systems. Overall height is 440 mm, and the enclosure uses design version 1 within line version 1, which keeps connector placement consistent with matching drive controllers. These proportions let the HMS inverter fit above or beside other Rexroth power modules without altering cabinet depth, while preserving uniform airflow paths and practical cable routing inside the automation enclosure.
