Product Description:

The HCS03.1E-W0150-A-05-NNNN is a drive controller manufactured by Bosch Rexroth Indramat as part of the HCS IndraDrive Controllers series. This unit serves as the power and control interface between plant-level motion commands and the three-phase motors that move conveyors, tooling tables, or printing cylinders in automated machinery. By regulating current and voltage in real time, it supports accurate speed and torque control during changing load conditions. In automated lines, it coordinates the transition from incoming command values to controlled motor output without requiring a separate power stage. It is intended for cabinet-mounted systems that require coordinated operation with other IndraDrive components.

The controller uses internal air cooling driven by an integrated blower, so no external heat exchanger is required. This cooling method keeps the unit suitable for standard cabinet integration where airflow is managed at the enclosure level. The device supports up to 150 A peak current for short acceleration bursts without triggering overcurrent trips. The power stage accepts an AC 400–500 V mains supply with a tolerance of +10% and -15%, allowing installation on standard factory power networks. Within that supply class, the amplifier covers a 15–75 kW power range for different motor ratings. The IP20 housing limits finger ingress and conductive debris, but it is intended for enclosed panels with cabinet ventilation.

The unit is shipped as design version 1. Power is exchanged through an infeeding and regenerative supply section, so excess energy can return to the DC bus instead of being dissipated as heat during deceleration. This arrangement supports shared DC bus operation in multi-axis systems where braking energy from one axis can be used by another axis. It belongs to the HCS03 line, which uses the mounting dimensions and connector layout of that product line. The voltage code 05 indicates a 500 V class version for systems that use this supply category.
