Product Description:

The HCS03.1E-W0070-A-05-LNBV-AA is a modular drive controller manufactured by Bosch Rexroth Indramat and belongs to the HCS IndraDrive Controllers series. Acting as an inverter stage for synchronous or induction motors, the unit converts three-phase mains power into controlled output voltage and frequency so coordinated speed, torque, and positioning can be carried out in automated machinery. It combines the power section, control electronics, and protective monitoring in one housing, which helps conserve panel space in multi-axis systems. This layout supports applications such as conveyors, process equipment, and other machines that require consistent motor control across changing loads.

The housing carries an ingress protection rating of IP20, which means the terminals are finger-safe but the unit is not sealed against dust or water jets, so cabinet installation is required. During acceleration or load surges, the power stage can deliver a device peak current of 70 A, enabling short-term torque increases without exceeding thermal limits. The mains connection supports 3 × AC 400…500 V +10%, –15%, covering common industrial supply networks while allowing moderate voltage variation. Heat generated by the IGBTs is removed by an internal blower, so no external ducting is required.

Continuous output power falls within a 15 to 75 kW range, allowing the same controller frame to serve medium-sized pumps, conveyors, and process drives. The unit is design version 1. Its integrated power supply section is classified as Infeeding / Feeded, which means it can return energy to the DC bus or draw power from a shared intermediate circuit, depending on the system topology. The controller is part of the HCS03 line, and it uses voltage code 05 for the supported supply range and performance class.
