Bosch Rexroth HMS01.1N-W0110-A-07-NNNN Servo Inverter

Bosch Rexroth HMS01.1N-W0110-A-07-NNNN Servo Inverter for IndraDrive M Automation

The Bosch Rexroth HMS01.1N-W0110-A-07-NNNN is a single-axis servo inverter from the IndraDrive M series, engineered to deliver precision motor control with stable operating performance across demanding industrial production environments. As factories face increasing pressure to reduce operating load, minimize unplanned downtime, and maximize equipment utilization, the HMS01.1N-W0110-A-07-NNNN provides a robust, field-proven solution that addresses each of these challenges at the drive level.

Unlike conventional fixed-speed motor control approaches, the IndraDrive M platform enables dynamic torque and velocity regulation, allowing the servo axis to consume only the energy required for each motion profile. This translates directly into reduced idle-state power draw, lower heat generation in the control cabinet, and extended service intervals for connected mechanical components such as ball screws, gearboxes, and linear guides.

System Compatibility and Application

The HMS01.1N-W0110-A-07-NNNN is designed to operate as a core component within a fully integrated, industrial automation system. In a typical high-throughput production cell, the drive interfaces directly with a Bosch Rexroth IndraControl XM22 motion controller, which coordinates multi-axis positioning sequences and manages energy budgets across the entire servo system. The SERCOS III real-time communication backbone ensures deterministic cycle times below 1 ms, eliminating jitter-induced unplanned downtime caused by motion profile deviations.

On the power supply side, the HMS01.1N-W0110-A-07-NNNN is typically paired with a Rexroth HMV01.1E supply unit, which supports regenerative energy feedback to the mains — a critical feature in applications with frequent deceleration cycles such as press brakes, winding machines, and servo presses. This regenerative capability can reduce net operating load by Actual operating results depend on the installed system, load profile, and commissioning parameters.

For multi-axis configurations, the drive shares a common DC bus with other IndraDrive M modules such as the HMS01.1N-W0070-A-07-NNNN and HMS01.1N-W0210-A-07-NNNN, enabling energy exchange between braking and accelerating axes without routing power back through the AC mains. This inter-axis energy sharing is particularly effective in gantry systems, palletizers, and multi-spindle machining centers.

Power quality monitoring is handled upstream by a Rexroth IndraLogic XLC PLC, which aggregates operating load data from each drive node via PROFINET and forwards it to the plant-level SCADA or MES system. This closed-loop condition monitoring architecture allows production engineers to identify inefficient motion profiles, detect bearing wear through current signature analysis, and schedule predictive maintenance before a fault causes unplanned downtime.

I/O expansion for auxiliary equipment — including cooling fans, lubrication pumps, and safety interlocks — is managed through Rexroth Inline I/O modules connected to the IndraControl backplane. By integrating auxiliary load control into the same automation platform, engineers can implement coordinated energy shutdown sequences that power down non-essential subsystems during low-production periods, further reducing standby operating load.

For applications requiring human-machine interaction, the Rexroth IndraControl VPP 40 panel PC provides a high-resolution interface for real-time energy dashboards, drive diagnostics, and production KPI visualization. Operators can monitor per-axis power consumption, compare actual versus target energy profiles, and trigger manual operational-efficiency modes directly from the HMI without interrupting the production cycle.

Maintenance and Replacement Notes

In automotive body-in-white welding lines, the HMS01.1N-W0110-A-07-NNNN drives servo positioners that index workpiece carriers between welding stations. By implementing S-curve acceleration profiles through the IndraDrive M firmware, peak current demand is reduced by up to 20% compared to trapezoidal motion profiles, directly lowering the installed power requirement and reducing transformer sizing costs.

In packaging machinery — particularly horizontal flow wrappers and case erectors — the drive’s high dynamic response enables film tension control with sub-millisecond correction cycles. This eliminates film waste caused by tension spikes during product infeed, reducing both material consumption and the energy required to process rejected packages downstream.

For press automation applications, the regenerative braking capability of the HMS01.1N-W0110-A-07-NNNN captures kinetic energy during the return stroke of the press ram and feeds it back to the DC bus, where it is consumed by other axes performing simultaneous acceleration. In a 6-axis servo press line running at 40 strokes per minute, this energy recovery mechanism can offset 20–25% of total drive operating load over an 8-hour shift.

Predictive maintenance integration is achieved through the drive’s built-in condition monitoring functions, which continuously track motor winding temperature, bearing vibration signatures via encoder feedback analysis, and DC bus voltage ripple. Anomalies are flagged to the IndraControl PLC, which can automatically reduce axis speed or load to extend component life while alerting maintenance personnel — preventing catastrophic failures that would otherwise result in hours of unplanned downtime and significant unplanned downtime from emergency restart procedures.
