Rexroth HMS01.1N-W0210-A-07-NNNN IndraDrive Single-Axis Inverter
Overview
The Rexroth HMS01.1N-W0210-A-07-NNNN (Ordering Code R911295328) is a high-performance single-axis inverter from the Bosch Rexroth IndraDrive M series. Designed as a modular drive converter, it is typically supplied with DC voltage from a central power supply unit and generates a regulated AC output with variable amplitude and frequency for precise motor control. Its high current capacity and robust construction make it a powerful and scalable solution for demanding multi-axis systems in industrial automation.
Technical Features
High Power and Current Capacity – This model has a maximum current of 210 A and a continuous current of 150.7 A. It is designed for a typical motor nominal power of 75 kW, making it suitable for high-power applications.
Wide DC Bus Voltage Range – The inverter operates on a nominal DC bus voltage of 700 V DC, with a supported input voltage range of 254 to 750 V DC. This wide voltage capability ensures compatibility with various power supply configurations.
Adjustable Output Frequency – The inverter provides an output voltage of up to 500 V AC. The output frequency is adjustable and depends on the switching frequency setting: 0-400 Hz at 4 kHz, 0-800 Hz at 8 kHz, 0-1200 Hz at 12 kHz, and 0-1600 Hz at 16 kHz. This wide frequency range enables high-speed operation for applications such as spindles, while also supporting low-speed positioning tasks.
Advanced Control Section (07) – The model includes an 07 control section, which provides a mounting slot for a single-axis control unit with various interfaces for connection to the automation environment. This includes support for encoder systems, safety technology, and other digital and analog signals.
Integrated Air Cooling – The inverter features an internal air cooling system with an integrated blower to ensure reliable operation under various load conditions. This robust cooling solution maintains performance and prevents overheating during intensive industrial processes.
Modular and Scalable Design – The inverter is part of the IndraDrive M modular system and can be used in multi-axis applications, where it is supplied with power from the DC bus of supply units like HMV01 or HMU05. For smaller axis packages, it can also be powered from the DC bus of an HCS converter, provided sufficient power reserve is available.
Robust Construction and Protection – The inverter features an IP20 protection class and is designed for industrial environments. It measures 440 mm in height, 200 mm in width, and 309 mm in depth, weighing approximately 16.25 kg.
Core Functionalities
Precise Motor Speed and Torque Control – The inverter converts DC voltage from the bus into a regulated AC output with variable amplitude and frequency, enabling precise control of motor speed, torque, and position for high-performance motion control.
Efficient Multi-Axis System Integration – In multi-axis applications, the inverter shares the DC bus with other axes, allowing regenerative energy from braking axes to be used by other accelerating axes, significantly improving overall system efficiency.
High Dynamic Response and Overload Capacity – The drive is designed to deliver high dynamic response with a peak current capability of 210 A for short-term overloads, making it suitable for applications requiring rapid acceleration, deceleration, and high peak torque.
Wide Speed Range and High Positioning Accuracy – The inverter supports a wide speed range up to 1,600 Hz and provides high positioning accuracy, making it suitable for precision motion control applications such as machine tool feed drives and robotics.
Flexible System Integration – The 07 control section supports various communication protocols, enabling easy integration with higher-level controllers such as PLCs, HMIs, and industrial PCs.
Configurable Motion Logic – The integrated technology functions can be configured based on motion logic to perform a wide and diverse range of process-oriented tasks.
