System Architecture & Signal Flow
The HCS02.1E-W0028-A-03-NNNN operates as a self-contained single-axis drive within the IndraDrive HCS topology. AC mains power is rectified to a 750 V DC bus, which feeds the IGBT inverter stage to generate variable-frequency, variable-voltage output to the connected servo motor (MSK/MSM series). The IndraDrive firmware processes position/velocity/torque commands received via the fieldbus interface (SERCOS III or PROFIBUS DP). Encoder feedback from the motor is evaluated by the integrated encoder circuit, closing position and current control loops at up to 4 kHz. The 24 V DC control supply maintains logic and communication functions independently of the main power stage, enabling safe power sequencing and STO functionality.

Technical FAQ
Q: Is the HCS02.1E-W0028-A-03-NNNN compatible with IndraDrive Cs motors?
A: Yes. The HCS02 series is designed to operate with Rexroth MSK and MSM servo motors within the IndraDrive ecosystem. Verify that the motor power rating does not exceed the drive’s continuous output current.
Q: What firmware version is pre-loaded?
A: Firmware version varies by production batch. Rexroth IndraWorks can update firmware to the latest release. Contact us for specific firmware version confirmation prior to order.
Q: Can this drive be used with third-party servo motors?
A: The HCS02 supports third-party motors with compatible encoder interfaces (EnDat, Hiperface, resolver) via appropriate encoder adapter modules. Consult Rexroth application engineering for the full compatibility matrix.
Q: What does the suffix -A-03-NNNN indicate?
A: The suffix encodes hardware options: “A” = standard housing, “03” = firmware/communication option set, “NNNN” = no additional hardware options. Variants with different suffixes may include additional I/O, safety, or communication options.
Q: Do you provide export documentation for customs clearance?
A: Yes. Full export documentation including commercial invoice, packing list, and certificate of origin is provided with every international shipment.
