Product Description:
The HCS03.1E-W0070-A-05-LNBV is a drive controller produced by Bosch Rexroth Indramat and supplied in the HCS IndraDrive Controllers series. It is installed in multi-axis automation cabinets where it governs the exchange of energy between the mains and synchronous or induction servo motors, delivering closed-loop speed and torque control while coordinating with higher-level PLCs. As the regulating element in the IndraDrive platform, the unit sets motor operating points, monitors feedback, and triggers protective responses during overload or mains disturbances. It also supervises feedback signals so the connected motor can respond accurately to commanded changes in speed or load.
This controller is connected to a three-phase supply rated at 3 × AC 400–500 V (+10 %, –15 %), allowing direct integration into common factory distribution networks without step-down transformers. Within that input range, it covers a power bandwidth of 15 to 75 kW, so the same frame can manage moderate pump drives as well as larger material-handling axes. During fast accelerations it can source up to 70 A of device peak current, a reserve used by the control stage for short-term torque demands during transient loading. An internal airflow path with an integrated blower provides internal air cooling, moving heat away from the power semiconductors without external ducting. Component surfaces are protected only against finger contact and settled dust because the housing is rated at IP20.
The model belongs to the HCS03 line, so mechanical dimensions and terminal layouts follow that sub-series for consistent panel integration. The unit is design version 1, indicating the first internal revision of this controller platform. The voltage adaptation within the type code is shown by 05, which aligns the intermediate-circuit components with the stated mains window. Because the power section can operate either as an infeed converter or as a DC-bus consumer, its supply category is infeeding and fed operation, enabling common-bus configurations that recycle braking energy among neighboring axes.
