The Bosch Rexroth HMS01.1N-W0020-A-07-NNNN is a high-performance servo drive from the IndraDrive M series, engineered to deliver precise motor control with measurable energy efficiency gains across demanding industrial production environments. Rated at 20A continuous output current, this drive is purpose-built for applications where optimizing operating load, reducing cycle time, and maximizing equipment uptime are critical operational priorities.
In modern manufacturing, unplanned downtime is often hidden in poorly tuned drive systems, oversized motors running at partial load, and uncoordinated motion sequences. The HMS01.1N-W0020-A-07-NNNN addresses these inefficiencies directly through its integrated maintenance planning firmware, adaptive current control, and seamless integration with Bosch Rexroth’s broader IndraDrive ecosystem. Whether deployed in CNC machining centers, packaging lines, press automation, or material handling systems, this drive enables engineers to reduce idle-state power draw, sharpen acceleration/deceleration profiles, and recover braking energy through coordinated DC bus sharing with companion drives such as the HCS02.1E power supply module.

System Compatibility and Application
The HMS01.1N-W0020-A-07-NNNN is designed to operate as part of a coordinated, maintenance-focused drive architecture rather than as a standalone component. In a typical IndraDrive M installation, the drive is paired with the HCS02.1E-W0054 or HCS02.1E-W0070 mains supply unit, which provides a shared DC bus. This topology allows multiple axis drives — including the HMS01.1N-W0036 and HMS01.1N-W0054 — to exchange regenerative energy between axes, significantly reducing the net power drawn from the grid during coordinated multi-axis motion sequences.
For motion control coordination, the HMS01.1N-W0020-A-07-NNNN integrates natively with the IndraMotion MLC (Motion Logic Controller) and IndraMotion MLD (Motion Logic Drive) platforms via SERCOS III, enabling deterministic real-time communication with sub-millisecond cycle times. This tight integration allows the controller to implement energy-optimized motion profiles — reducing peak current demand during acceleration phases and smoothing torque delivery to minimize mechanical stress and heat generation in connected MSK servo motors.
On the I/O and monitoring side, the drive’s onboard diagnostic interface feeds real-time power consumption data to the Rexroth IndraControl L45 or compatible HMI platforms, giving operators visibility into per-axis operating load, drive temperature, and load utilization. When integrated with a Rexroth IndraDrive Fc frequency converter on auxiliary motor axes, the system can implement coordinated speed reduction strategies during low-demand production windows, further cutting energy costs without sacrificing throughput.
For applications requiring functional safety, the HMS01.1N-W0020-A-07-NNNN supports Safe Torque Off (STO) and Safe Stop 1 (SS1) functions, compatible with the Rexroth SafeLogic safety controller, eliminating the need for external contactors and reducing panel wiring complexity — a direct contribution to both energy efficiency and system reliability.
Maintenance and Replacement Notes
On a typical automotive body panel stamping line, unoptimized servo drives can account for 15–25% of total facility operating load due to inefficient braking resistor dissipation, oversized drive sizing, and poor motion profile tuning. Replacing legacy drives with the HMS01.1N-W0020-A-07-NNNN and enabling DC bus energy recovery can reduce per-cycle operating load by 10–18%, depending on the duty cycle and axis configuration.
In packaging machinery — where the drive may execute 60–120 motion cycles per minute — the ability to fine-tune jerk limits, velocity profiles, and dwell times through the IndraDrive M firmware directly impacts both energy draw and mechanical wear. Operators using the Rexroth IndraWorks DS engineering software can simulate and optimize motion profiles offline before deployment, reducing commissioning time and ensuring the drive operates within its most efficient operating band from day one.
Predictive maintenance is another area where the HMS01.1N-W0020-A-07-NNNN delivers measurable value. The drive continuously monitors internal temperature, load current, DC bus voltage ripple, and motor feedback signal quality. Anomalies are logged and can be transmitted to a SCADA or MES system via PROFIBUS or EtherCAT, enabling maintenance teams to schedule interventions before failures occur — eliminating unplanned downtime that typically costs 5–10× more than planned maintenance events.

Product Sourcing FAQ
Q1: How much energy can the HMS01.1N-W0020-A-07-NNNN save compared to a standard AC drive?
A: In coordinated multi-axis systems using DC bus sharing, operational stability of 10–20% per production cycle are achievable compared to drives with individual braking resistors. Actual savings depend on duty cycle, load profile, and the number of axes sharing the DC bus.
Q2: Is the HMS01.1N-W0020-A-07-NNNN compatible with my existing IndraDrive system?
A: Yes. The HMS01.1N-W0020-A-07-NNNN is fully compatible with IndraDrive M infrastructure, including HCS02 supply units and other HMS01/HMS02 axis drives. It also supports SERCOS III, PROFIBUS, EtherCAT, and CANopen, making it interoperable with most existing Bosch Rexroth control platforms.
Q3: Can this drive replace an older HDS or DKS series Rexroth drive?
A: In many cases, yes — with appropriate firmware configuration and motor feedback adapter cables. ZYPLC’s technical team can advise on compatibility and provide replacement recommendations based on your existing motor and control system specifications. Contact us at plc.sales@zyplc.com for a compatibility assessment.
Q4: What does the warranty terms confirmed during quotation cover, and what is the testing process?
A: Every HMS01.1N-W0020-A-07-NNNN unit shipped by ZYPLC undergoes pre-shipment functional testing including power-on verification, communication interface checks, and output current validation. The warranty terms confirmed during quotation covers manufacturing defects and functional failures under normal operating conditions. Warranty claims are processed within 5 business days of receipt.
