Product Description:

The HCS02.1E-W0012-A-03-NNNN-AA is manufactured by Bosch Rexroth that joins the top-selling HCS IndraDrive Controllers series. As a compact drive controller, it features input voltage range of 3 x AC 230...480 V (-15 %...+10 %) that accommodates mains variations which ensures stable operation under fluctuating supply conditions. A 50/60 Hz input frequency tolerance of ~2 % matches global utility standards which maintains consistent drive performance. Rated current of 12 A delivers sufficient drive capacity which supports medium-power single-axis applications.

A 24 V DC control voltage tolerance of -15 %...+20 % stabilizes logic circuits, thus avoids undervoltage faults. Continuous output current of 12 A for this module at a 4 kHz switching frequency maintains steady motor torque which preserves motion smoothness. Output power varies according to connected motor type which provides flexibility for synchronous or asynchronous drives. Moreover, the process of internal fan cooling removes heat via an integrated blower which prevents thermal overload without external chillers. IP rating of IP20 blocks solid objects above 12 mm, thereby safeguards live components in control cabinets. A control cabinet mounting form factor ensures secure installation within electrical enclosures which minimizes wiring exposure. Dimensions of around 105 mm x 355 mm x 263 mm deliver a narrow footprint which increases space efficiency.

The base version of HCS02.1E-W0012-A-03-NNNN-AA controller lacks a communication interface which reserves the control unit slot for option cards. Design version 1 aligns hardware revisions with firmware updates that simplifies lifecycle management. Also, a single control unit slot accepts fieldbus or scalable interface cards to extend connectivity options. For this variant, the power ranges from 1.5 kW to 11 kW covers typical industrial motor requirements. Operating temperature up to 40 degrees C secures reliable function in standard industrial environments, hence avoids derating under moderate heat.
