Selection Guide
Use the following criteria to confirm the HMS01.1N-W0070-A-07-NNNN is the correct model for your application:
- Step 1 – Current Rating: Confirm motor continuous current ≤ 70 A (peak current per datasheet)
- Step 2 – Supply Voltage: Verify 3-phase AC 200–480 V availability at cabinet
- Step 3 – Communication Protocol: Confirm SERCOS II or PROFIBUS DP is used (slot 07)
- Step 4 – Safety Requirements: NNNN = no integrated safety; if STO/SS1 required, select HMS01.1N-W0070-A-07-NNNV or similar
- Step 5 – Axis Count: HMS = single axis; for dual-axis, consider HMD series
- Step 6 – Firmware: Match firmware version to existing system to avoid parameter incompatibility

Replacement & Compatibility FAQ
Q: Can I replace HMS01.1N-W0070-A-07-NNNN with an HMS01.1E variant?
A: The HMS01.1E (Economy) series shares the same power stage but may have reduced feature sets. Verify IndraWorks compatibility and firmware support before substitution.
Q: Is the communication slot (07) field-configurable?
A: No. The communication option is factory-configured. Ensure your system uses SERCOS II or PROFIBUS DP before ordering.
Q: What is the difference between HMS and HMD series?
A: HMS = single-axis inverter; HMD = double-axis inverter. Both share the same IndraDrive platform and supply module infrastructure.
Q: Can this unit work with non-Rexroth motors?
A: Yes, with proper motor data configuration in IndraWorks. Third-party motor commissioning requires manual parameter entry and may void warranty.
Q: Do you offer repair or exchange service?
A: Yes. Contact us for repair evaluation, exchange programs, and emergency loan units for critical downtime situations.
