Bosch Rexroth HCS02.1E-W0054-A-03-NNNN – Compact AC Servo Drive with 5.4 kVA Output | IndraDrive C Platform
Engineering Background: The IndraDrive C (HCS02) series represents Bosch Rexroth’s compact, cost-optimized servo drive platform engineered for single-axis and multi-axis motion control in industrial automation. Designed to operate within the SERCOS III / PROFIBUS / EtherCAT ecosystem, HCS02 drives deliver deterministic torque, velocity, and position control for demanding production environments.
Product Positioning: The HCS02.1E-W0054-A-03-NNNN is a 5.4 kVA rated AC inverter unit targeting machine tool, packaging, printing, and material handling applications where compact footprint and high dynamic response are critical. This unit is sourced as verified surplus/refurbished stock and is fully tested prior to shipment.

System Architecture & Signal Flow
The HCS02.1E-W0054-A-03-NNNN operates as a standalone single-axis drive or as a slave axis within a multi-axis IndraDrive topology sharing a common DC bus (HMV supply unit). Signal flow: AC Mains → HMV/HCS Rectifier → DC Bus → HCS02 Inverter Stage → Motor Encoder Feedback → Closed-Loop Control → PROFIBUS DP Command Interface → PLC/CNC Controller.
The drive accepts incremental and absolute encoder feedback (EnDat 2.1/2.2, Hiperface, resolver) via the X8 motor feedback connector, enabling sub-micron positioning accuracy in coordinated multi-axis applications.

Technical FAQ
Q: Is this drive compatible with non-Rexroth motors?
A: The HCS02 is optimized for Rexroth IndraDyn motors. Third-party motor compatibility requires custom motor data set configuration via IndraWorks DS and is possible but not guaranteed.
Q: What is the difference between W0054 and W0070 variants?
A: W0054 = 5.4 A continuous output current; W0070 = 7.0 A. Select based on your motor’s rated current and peak torque requirements.
Q: Can this unit replace an HCS02.1E-W0054-A-03-B2NN?
A: The NNNN suffix indicates no optional modules. If your application requires the B2 safety option (STO via X41), this unit is not a direct drop-in replacement without hardware modification.
Q: Is PROFIBUS DP the only fieldbus option?
A: For this specific part number (option code 03), yes. Other variants support SERCOS III (S3), EtherCAT (EC), and PROFINET (PN). Contact us if you need a different fieldbus variant.
Q: Do you provide commissioning support?
A: We can provide parameter backup files and remote guidance. On-site commissioning is not included but can be arranged through our partner network.
