HCS02.1E-W0054-A-03-NNNN

The Bosch Rexroth Indramat HCS02.1E-W0054-A-03-NNNN is a drive controller in the HCS IndraDrive Controllers series. It supplies modulated power to servo or induction motors, allowing automation systems to adjust speed, position, and torque electronically rather than mechanically. The unit integrates into production lines, packaging equipment, and material-handling stations where compact power electronics and coordinated motion are required.

Design Version 1 sustains a continuous output current of 20.6 A at a switching frequency of 4 kHz, allowing stable operation during constant-speed duty cycles. For rapid transients, the inverter supplies a peak current of 54 A. With a line choke fitted, continuous power reaches 10 kW, and peak power increases to 16 kW; without the choke, the corresponding limits are 7 kW and 12 kW. Power losses total 270 W, and the DC bus has 0.405 mF of capacitance to smooth regenerated energy. The controller draws 19 A from the DC link, while its control electronics consume 23 W. A maximum output frequency of 1600 Hz supports high-speed motors. The controller can absorb 9 kWs of braking energy before reaching its thermal limits.

The controller accepts a three-phase AC 200–500 V supply with a ±10% tolerance and draws an inrush current of 2.8 A while the bus capacitors charge. An internal blower circulates cooling air through the unit, reducing the need for additional cabinet ducting. The enclosure provides IP20 protection against accidental contact and solid objects larger than the applicable size threshold. During short braking cycles, the brake chopper can dissipate 18 kW. The unit has a minimum insulation resistance of 8 MΩ, and the logic supply has an overvoltage limit of 33 V. Its 1.5 to 11 kW power range supports many medium-power axes, while the infeed and regenerative power supply topology allows compatible HCS02 units to exchange energy through a shared DC bus.
