Rexroth HMS01.1N-W0036-A-07-NNNN Servo Drive

Rexroth HMS01.1N-W0036-A-07-NNNN Servo Drive for IndraDrive Automation

The Bosch Rexroth HMS01.1N-W0036-A-07-NNNN is a high-performance AC servo drive from the IndraDrive series, engineered to deliver precision motor control while minimizing operating load across demanding industrial production environments. As factories face increasing pressure to reduce operational costs and carbon footprints, the HMS01.1N-W0036-A-07-NNNN stands out as a cornerstone component for industrial automation system — enabling plant engineers to optimize drive efficiency, reduce idle-state power draw, and extend equipment service intervals.

Rated at 36A continuous output current, this single-axis servo drive module integrates seamlessly into Rexroth IndraDrive multi-axis systems, sharing a common DC bus with companion power supply units such as the HMV01.1E-W0120 supply module, which enables regenerative energy feedback to the grid — a critical feature for reducing net operating load in servo-intensive production lines. When paired with the HCS02.1E-W0054 compact converter, the HMS01.1N-W0036-A-07-NNNN supports flexible single-axis configurations where shared bus topology is not required, giving system integrators the freedom to design energy-efficient drive architectures tailored to specific machine requirements.

System Compatibility and Application

Deploying the HMS01.1N-W0036-A-07-NNNN within a well-designed IndraDrive system architecture unlocks significant operational stability at the system level. The drive’s shared DC bus topology allows kinetic energy recovered during motor deceleration to be redistributed to other axes still accelerating — a process managed by the HMV01.1E-W0120 or HMV02.1E regenerative supply modules. This inter-axis energy exchange reduces the total power drawn from the mains supply, directly lowering electricity costs in high-cycle applications such as servo press lines and multi-axis robotic cells.

For motion control coordination, the HMS01.1N-W0036-A-07-NNNN communicates with higher-level controllers via SERCOS III or PROFIBUS DP, enabling tight synchronization with Rexroth IndraMotion MLC or IndraMotion MTX CNC controllers. This real-time communication backbone ensures that drive commands are executed with microsecond-level precision, eliminating unnecessary motor dwell time and reducing unplanned downtimed during positioning cycles. The CSB01.1N and CSE01.1C control section modules, which plug directly into the HMS01.1N drive housing, extend the drive’s functional scope — supporting advanced encoder feedback, safety functions (STO, SS1), and multi-encoder management for complex servo axes.

On the motor side, the HMS01.1N-W0036-A-07-NNNN is optimized for use with Rexroth MSK070 and MSK100 synchronous servo motors, which feature high torque density and low rotor inertia — characteristics that directly translate to faster acceleration profiles, shorter cycle times, and reduced energy per production unit. When the drive’s auto-tuning and adaptive control algorithms are activated, the system continuously adjusts current and voltage vectors to maintain peak motor efficiency across varying load conditions, preventing the energy losses associated with over-excitation or sub-optimal flux control.

For power quality monitoring and energy data acquisition, integrating the HMS01.1N-W0036-A-07-NNNN with a Rexroth RMB02 power measurement module or a compatible condition monitoring gateway allows plant engineers to log real-time power consumption per axis, identify inefficient operating windows, and generate energy reports for ISO 50001 compliance. This data-driven approach to drive management transforms the servo system from a passive actuator into an active participant in the factory’s maintenance planning strategy.

Maintenance and Replacement Notes

In a typical automotive body panel stamping line, servo axes driven by HMS01.1N-W0036-A-07-NNNN modules operate in highly repetitive motion profiles — accelerating, dwelling, and decelerating hundreds of times per hour. Without regenerative drive technology, the kinetic energy released during each deceleration phase is dissipated as heat through braking resistors, representing a direct and measurable energy loss. With the HMS01.1N integrated into a common DC bus system, this energy is instead fed back to accelerating axes, reducing peak demand from the supply module by up to 30% in high-inertia applications.

Beyond energy recovery, the HMS01.1N-W0036-A-07-NNNN contributes to production line optimization through its advanced diagnostic and condition monitoring capabilities. The drive continuously monitors motor winding temperature, encoder signal quality, DC bus voltage stability, and output current harmonics. Deviations from baseline parameters trigger predictive maintenance alerts — transmitted via the IndraMotion MLC controller to the plant’s SCADA or MES system — allowing maintenance teams to schedule interventions during planned downtime rather than reacting to unplanned failures. This shift from reactive to predictive maintenance reduces mean time between failures (MTBF) and lowers the total cost of ownership over the drive’s operational life.

For facilities managing spare parts inventory, ZYPLC maintains ready stock of the HMS01.1N-W0036-A-07-NNNN alongside compatible components including the HMD01.1N double-axis module and CFL01.1 filter modules, ensuring that replacement drives can be shipped and installed within the same business day — minimizing production downtime and protecting line throughput targets. Every unit undergoes functional load testing and parameter verification before dispatch, and is covered by a warranty terms confirmed during quotation from the date of shipment.

Product Sourcing FAQ

Q1: How much energy can the HMS01.1N-W0036-A-07-NNNN save compared to a standard non-regenerative drive?
In multi-axis IndraDrive systems using a shared DC bus with an HMV01 or HMV02 regenerative supply module, operational stability of Actual operating results depend on the installed system, load profile, and commissioning parameters. Single-axis configurations using the HCS02 converter do not benefit from inter-axis energy exchange but still gain from the drive’s high-efficiency PWM control and standby power reduction features.

Q2: Is the HMS01.1N-W0036-A-07-NNNN compatible with my existing IndraDrive system?
The HMS01.1N-W0036-A-07-NNNN is compatible with Rexroth IndraDrive M (HMS/HMD) multi-axis systems using HMV01 or HMV02 supply modules. It accepts CSB01 or CSE01 control section plug-ins and supports MSK, MKD, and MHD motor families. Firmware version and control section selection determine available communication protocols (SERCOS III, PROFIBUS, EtherCAT). Please confirm your existing supply module rating and control section type before ordering.

Q3: What is the recommended replacement process for a failed drive on a live production line?
ZYPLC recommends maintaining at least one spare HMS01.1N-W0036-A-07-NNNN in your critical spares inventory. Replacement involves: (1) safe isolation of the DC bus and motor power, (2) transfer of the control section (CSB01/CSE01) from the failed unit to the replacement drive, (3) restoration of drive parameters via the IndraWorks engineering tool or parameter backup file, and (4) functional test under no-load conditions before resuming production. ZYPLC’s technical team can provide parameter backup support remotely.

Q4: What does the warranty terms confirmed during quotation cover, and what is the testing process before shipment?
Every HMS01.1N-W0036-A-07-NNNN shipped by ZYPLC undergoes a full functional test including DC bus energization, control section communication verification, output current measurement, and encoder interface validation. The warranty terms confirmed during quotation covers manufacturing defects and functional failures under normal operating conditions. It does not cover damage resulting from incorrect installation, overvoltage events, or operation outside specified environmental parameters. Warranty claims are processed within 5 business days of receipt of the returned unit.
