Description

Technical Architecture & Functional Positioning

The HCS02.1E-W0028 is the economy-performance member of the IndraDrive C series, delivering full converter functionality in the smallest mechanical footprint of the 400–500 V class. It integrates power stage, control unit, braking chopper, and Multi-Ethernet interface, and STO safety in one housing — reducing cabinet volume by more than 50 % compared to traditional separate power/control designs.

Its 32-bit DSP achieves current loop cycles of 62.5 μs and velocity loops of 125 μs, providing torque rise times below 1 ms — performance previously reserved for higher-power models. The integrated energy recovery capability via shared DC bus and internal braking chopper makes it ideal for applications with moderate regenerative duty cycles without external resistors.

Engineers particularly value the “one-cable solution” compatibility (Hiperface DSL or EnDat 2.2) that reduces motor wiring to a single hybrid cable, cutting installation cost and improving EMC behaviour in long cable runs.

Typical Application Scenarios

Packaging machines (form-fill-seal, cartoning) requiring synchronized electronic gearing and cam profiles
General material handling and conveyor systems with frequent start-stop cycles
Small to medium printing and labelling machines needing precise web tension control
Automated assembly lines using linear motors or torque motors up to 50 Nm
Retrofit replacement for older Rexroth EcoDrive 03 or Indramat DKC02/DKC03 systems
Textile and woodworking machinery where compact size and low heat dissipation are critical

Quality Standards & Testing Procedures

Our SOP for the HCS02.1E-W0028 has been executed on several thousand IndraDrive units and is specifically tuned to catch the most common failure modes seen in the field (IGBT degradation, fan bearing wear, capacitor aging).

Visual & Mechanical Inspection

20× microscopic inspection of IGBT solder joints and DC bus bars
Capacitance and ESR measurement of all electrolytic capacitors
Fan bearing play and impeller cleaning

Live Burn-In & Load Testing

Minimum 48-hour continuous operation at 40 °C, 8 kHz switching, 28 A RMS using water-cooled RL load bank
Real-time monitoring of DC bus voltage, IGBT junction temperature, and fan RPM
Thermal imaging to verify heatsink temperature gradient <8 °C
