Product Description:

The HCS03.1E-W0150-A-05-LNBN is a drive controller produced by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. As a stand-alone power stage, it interfaces between a three-phase plant supply and synchronous or induction motors, issuing controlled current and voltage so axes can accelerate, brake, or hold position under numeric or PLC command. Within an automation cell, the unit forms the electrical core of conveyor, packaging, and handling stations by converting mains power into regulated motor energy while reacting to feedback in real time.

The controller uses internal air cooling through an integrated blower, so cabinet airflow is directed across its heat sink without external ducting. During transient mechanical demands, it can deliver up to 150 A of peak output current, allowing short bursts of torque before returning to continuous limits set in the paired drive. An enclosure rating of IP20 limits installation to clean, closed panels but leaves the connector rows directly accessible for wiring. The supply side accepts 3-phase 400–500 V AC with a +10 / -15 percent tolerance, matching common industrial mains. Across that voltage band, the device spans a continuous power window of 15–75 kW, so one hardware class can cover multiple machine sizes. In addition, the DC bus is configured for infeeding operation, allowing surplus regenerative energy from braking axes to be returned to the line or shared with neighboring drives instead of being dissipated as heat.

Controller identity is fixed as Design Version 1, which identifies the hardware revision used for its parameter structure and fault-code handling. The electronics belong to the HCS03 line, which sets the mechanical outline, connector pitch, and supported accessory modules for this platform. The unit also carries Voltage Code 05, which marks the 500 V class used by the power section.
