Rexroth HMS01.1N-W0070-A-07-NNNN Inverter for IndraDrive HMS01

Rexroth HMS01.1N-W0070-A-07-NNNN Inverter for IndraDrive HMS01

The Bosch Rexroth HMS01.1N-W0070-A-07-NNNN is a high-performance single-axis inverter drive engineered for seamless integration within the IndraDrive HMS01 modular control architecture. Rated at 70A continuous output current, this inverter occupies a critical position in the motion control layer of multi-axis automation systems, providing precise torque and velocity regulation for demanding servo applications across manufacturing, power generation, petrochemical processing, water treatment, metallurgy, and packaging lines.

Unlike standalone drives, the HMS01.1N-W0070-A-07-NNNN is designed from the ground up for system integration — meaning its value is fully realized when deployed as part of a coordinated IndraDrive system. It shares a common DC bus with adjacent inverter modules, communicates natively with the IndraDrive control section (CSH, CSB, or CDB variants), and synchronizes motion profiles across axes through the SERCOS III or PROFINET real-time network backbone. This architecture eliminates redundant power conversion stages, reduces cabinet footprint, and dramatically simplifies commissioning and long-term maintenance.

From a system hierarchy perspective, the HMS01.1N-W0070-A-07-NNNN sits between the power supply module (HMV01 or HMV02 supply unit) and the servo motor (MSK, MKD, or MHD series), receiving DC bus voltage from the supply section and delivering precisely controlled three-phase AC output to the motor. The control section mounted above it handles trajectory planning, fieldbus communication, and safety logic, while the drive itself manages current loop execution at high switching frequencies to ensure smooth, low-ripple torque delivery even under dynamic load changes.

In layered automation architectures, this inverter interfaces upward to the PLC or motion controller layer — typically an IndraMotion MLC or a Siemens SIMATIC S7 controller via PROFINET — and downward to the mechanical execution layer through the motor feedback interface. The drive’s integrated encoder evaluation supports resolvers, EnDat 2.1/2.2 absolute encoders, and incremental TTL/HTL encoders, enabling precise position feedback without external signal conditioning hardware.

For system engineers focused on redundancy and availability, the HMS01.1N-W0070-A-07-NNNN supports hot-swap replacement within the IndraDrive modular frame when combined with appropriate bus cover and DC bus capacitor discharge management. Its parameter set can be stored on the control section’s memory card (SD card or CFcard), allowing rapid axis replacement without re-commissioning — a critical advantage in high-availability production environments where downtime carries significant cost.

Supply chain continuity and long-term serviceability are equally important in industrial control system design. ZYPLC maintains availability subject to RFQ confirmation of the HMS01.1N-W0070-A-07-NNNN alongside complementary IndraDrive components including HMV01.1E supply units, HCS02 and HCS03 compact inverters, CSH01 and CSB02 control sections, DAE01 and DAE02 axis expansion modules, and NFD03 mains filters. This breadth of inventory ensures that system integrators and maintenance teams can source complete drive train assemblies or individual replacement modules from a single, reliable supplier.

System Compatibility Notes

The HMS01.1N-W0070-A-07-NNNN achieves its full performance potential when integrated within a complete IndraDrive system architecture. A typical multi-axis configuration begins with an HMV01.1E-W0120 regenerative supply unit that rectifies incoming three-phase mains (400–480 V AC) and maintains a stable DC bus shared across all inverter modules in the same cabinet section. Adjacent to the HMS01.1N-W0070-A-07-NNNN, engineers commonly deploy HMS01.1N-W0036-A-07-NNNN or HMS01.1N-W0054-A-07-NNNN inverters for lower-power axes, creating a balanced multi-axis drive train on a single shared bus.

The control section — typically a CSH01.1C or CSB02.1B — mounts directly to the inverter and handles all high-level motion functions: trajectory interpolation, electronic gearing, cam profiling, and safety STO (Safe Torque Off) logic. The DAE01.1 axis expansion module extends the system to additional axes without requiring separate supply units, preserving DC bus sharing efficiency. For applications requiring fieldbus connectivity to a host PLC, the PROFINET communication module (CDB01.1) provides deterministic real-time data exchange with cycle times as low as 1 ms.

At the motor interface, the HMS01.1N-W0070-A-07-NNNN is optimally paired with MSK100C or MSK100D servo motors in the 70A current class, with motor parameters stored in the drive’s electronic nameplate (ENP) system for automatic identification. The NFD03.1 mains filter upstream of the supply unit ensures EMC compliance in CE-marked machine installations, while HNL01.1 line chokes protect against supply voltage disturbances in weak grid environments.

Industrial Application Notes

In automotive and general manufacturing environments, the HMS01.1N-W0070-A-07-NNNN drives servo axes on robotic welding positioners, precision assembly stations, and CNC machining centers where dynamic stiffness and sub-millisecond torque response are non-negotiable. Its shared DC bus architecture allows regenerative energy from decelerating axes to be immediately consumed by accelerating axes on the same bus, reducing net energy consumption by up to 30% compared to individual drive installations.

In power generation and utilities, the drive is deployed in turbine blade pitch control systems and generator excitation test rigs, where its high continuous current rating and robust thermal management support extended duty cycles. Petrochemical and process industries utilize the HMS01.1N-W0070-A-07-NNNN in compressor control systems and reactor agitator drives, where the drive’s integrated safety functions (STO, SS1) satisfy SIL 2 requirements without external safety relays.

Water treatment facilities deploy this inverter in pump and blower control applications integrated with SCADA systems via PROFINET, enabling remote diagnostics and predictive maintenance scheduling. In mining and metallurgy, the drive’s robust DC bus design handles the high inertia loads of conveyor drives and rolling mill auxiliary axes, with the shared bus providing inherent protection against voltage spikes generated by large motor switching events.

Packaging and material handling lines benefit from the drive’s electronic cam and gearing functions, which synchronize multiple axes — infeed, sealing, cutting, and discharge — without mechanical line shafts, reducing mechanical complexity and enabling rapid format changeover through parameter-only recipe switching.

Product Compatibility FAQ

Q1: Is the HMS01.1N-W0070-A-07-NNNN compatible with both SERCOS III and PROFINET control sections?
A: Yes. The HMS01.1N-W0070-A-07-NNNN inverter module is communication-agnostic at the hardware level — the fieldbus protocol is determined by the control section (CSH, CSB, or CDB variant) mounted to it. This means the same inverter can be used in SERCOS III-based IndraDrive M systems or PROFINET-based IndraDrive Cs/Mi systems, providing significant flexibility for system architects managing mixed-protocol installations or planning future network migrations.

Q2: Can this inverter be replaced in the field without full system re-commissioning?
A: Yes, provided the replacement unit is the same part number and the system uses a CSH or CSB control section with an SD/CF memory card storing the axis parameter set. The control section retains all drive parameters, motor data, and application-specific tuning values independently of the inverter module. After physical replacement and DC bus discharge verification, the system performs an automatic parameter download to the new inverter on power-up, restoring full axis functionality typically within one machine cycle. This capability is a key advantage of the IndraDrive modular architecture for high-availability applications.

Q3: What does the from ZYPLC cover, and what support is available during the warranty period?
A: The covers all verified hardware defects identified under normal operating conditions consistent with Bosch Rexroth’s published environmental and electrical specifications. During the warranty period, ZYPLC provides direct technical support for installation, commissioning, and fault diagnosis via phone and email. In the event of a confirmed hardware fault, ZYPLC will arrange replacement unit dispatch with priority handling to minimize system downtime. Pre-shipment test documentation is available for all units, and our engineering team can assist with IndraDrive system configuration review at no additional charge during the warranty period.
