System Architecture & Signal Flow
The HMS01.1N-W0020-A-07-NNNN operates within the IndraDrive M system topology as follows:
- Power Supply: Shared DC bus fed by an HMV or HCS supply unit; the HMS axis module draws from the common DC rail
- Control Communication: SERCOS III ring connects the CNC/PLC master (e.g., Rexroth IndraMotion MTX or Siemens 840D) to each HMS axis via fiber or copper Ethernet
- Feedback Loop: Motor encoder signals (Hiperface/EnDat) feed directly into the HMS DSP for closed-loop current, speed, and position control at 16 kHz PWM
- Safety Channel: STO input (24 V DC) connects to the machine safety relay or safety PLC; de-energizing disables gate drive without removing DC bus power
- I/O Expansion: Optional I/O extension modules (HAS) mount directly to the HMS unit for local digital/analog I/O without additional wiring runs

Technical FAQ
Q: Is the HMS01.1N-W0020-A-07-NNNN compatible with a Siemens 840D controller?
A: Yes. The SERCOS III interface (slot 07) is protocol-standard and interoperable with any SERCOS III master, including Siemens 840D sl and Fanuc 30i series, provided the drive firmware supports the required SERCOS profile.
Q: Can this drive operate on a 480 V supply without modification?
A: Yes. The HMS01.1N accepts 3-phase input from 200 V to 480 V AC without hardware modification. Ensure the DC bus supply unit (HMV/HCS) is rated for your mains voltage.
Q: What is the difference between HMS01.1N and HMS01.1E?
A: The HMS01.1N uses a standard (non-export-controlled) firmware variant. The HMS01.1E designation indicates an export-restricted version with enhanced safety or encryption features. For most industrial applications, the .1N variant is appropriate.
Q: Do you provide the original Rexroth documentation and parameter files?
A: Yes. We can supply the Rexroth project engineering documentation (DOK-INDRV*-HMS+HMD****-PR01-EN-P) and, where available, the original parameter backup file (.par) from the previous installation.
Q: What is the lead time for stock and non-stock units?
A: In-stock units ship within 1–3 business days. Non-stock or new OEM orders typically carry a 4–8 week lead time. Contact us for current availability.
