Product Description:

The HCS03.1E-W0100-A-05-LNBV-AA is a drive controller manufactured by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Within an automation cell, it functions as the command and power stage between the plant’s AC mains and connected servo or spindle motors. This role allows the unit to translate control commands into regulated motor current for positioning, speed control, and spindle operation. It coordinates torque, speed, and braking energy to keep multi-axis machinery synchronized during changes in load or direction. The line designation HCS03 places it in a controller group that shares dimensional interfaces and compatible configuration tools.

The controller is supplied from a three-phase network of 3 x AC 400 to 500 V, +10%/-15%, so it tolerates the voltage swings often found in large production lines. A device peak current of 100 A lets the unit handle rapid acceleration commands without saturating the power semiconductors. Its housing carries an IP20 rating, so the terminals are touch-safe but the unit still requires installation inside a cabinet. Thermal management relies on internal air cooling through an integrated blower, and the built-in fan pulls air across the heat sink to maintain semiconductor temperatures without external ducting. Because the cooling air is handled internally, the surrounding cabinet still needs clear airflow paths to avoid heat buildup around the chassis. With a continuous 15 to 75 kW power handling window, the model can supervise medium-size pump drives, packaging axes, or gantry modules while remaining within its thermal range.

The power section is classified for infeeding and regenerative operation, enabling the same module to draw energy from or return regenerated energy to a common DC bus. This arrangement supports energy sharing between accelerating and decelerating axes on the same machine. Hardware evolution is marked as Design Version 1, so matching accessories and parameter sets can be selected for this build. Voltage Code 05 aligns the controller with motors and power supply components intended for the stated mains window, which helps keep the electrical combination consistent across the drive system.
