Product Description:
The HCS03.1E-W0280-A-05-NNNV is a drive controller produced by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. It functions as the command and power interface between the facility’s AC mains and connected synchronous or induction motors, regulating torque, speed, and positioning tasks in automated cells and material-handling lines. This arrangement lets the unit deliver controlled motor power while staying responsive to commands from the surrounding automation system. It is suited for axes that must accelerate, decelerate, and hold speed consistently during repetitive machine cycles.
This controller uses internal air cooling through an integrated blower to move air across the heat sink, so no external ducting is required. An enclosure rating of IP20 allows cabinet mounting in dry, debris-free areas while still providing finger-safe protection. The mains section accepts three-phase power at 3 x AC 400 to 500 V (+10%, -15%), a range that accommodates typical plant voltage swings. Within that input window, the hardware supports a continuous output span of 15 to 75 kW, which suits several motor frame sizes. Control electronics and the onboard brake transistor are powered by DC 24 V from the shared DC bus, so a separate auxiliary supply is not required and the safety circuit remains active during mains outages.
The unit is design version 1 on this mechanical platform. The line designation HCS03 identifies the controller platform used for this model. Power routing is categorized as infeeding and fed operation, meaning the controller can return regenerated energy to the DC link or receive it from an upstream supply module. That arrangement supports installations that share braking energy across multiple connected axes. Voltage code 05 corresponds to the network class used by this power section and matches the insulation and component spacing inside the unit.
