Product Description:

The HCS03.1E-W0210-A-05-NNNV-AA is a drive controller produced by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. As a central component in multi-axis automation, the unit regulates motor torque, speed, and position by converting incoming mains power into a controlled DC bus and switched output phases. It is intended for machine tools, packaging lines, and handling systems that demand coordinated motion and dependable regenerative energy management. This operating role supports servo axes that must accelerate quickly, hold stable speed, and decelerate in a controlled manner under changing load conditions.

During operation, the device can deliver a peak output current of 210 A, allowing it to start and decelerate large servomotors without loss of control. The housing carries an IP20 rating, so live parts must be installed inside a cabinet while ventilation paths remain open for heat removal. The permitted mains supply is 3 × AC 400 to 500 V with a tolerance of +10%/−15%, so standard industrial plant power can be used without an isolation transformer. Within that voltage window, the controller covers a continuous power range of 15 to 75 kW, which suits mid-range spindles, pumps, and press axes. Thermal management is handled by internal air cooling, where an integrated blower moves air across the heat sinks without the need for external ducting. The enclosure rating is intended for protected cabinet installation rather than exposed mounting on the machine frame.

The unit is design version 1, which identifies the first design release for this controller format. The power section supports infeeding and DC-link-fed operation, so it can draw energy from the AC mains or operate from a shared DC link in a multi-axis system. This allows the controller to fit systems that distribute energy between several connected axes during motoring and braking. Control electronics use DC 24 V auxiliary power for low-voltage functions inside the controller. The assigned voltage code 05 corresponds to the 500 V class used by this model, which distinguishes it from lower-voltage members of the same controller family.
