Product Description:
The HCT02.1E-W0025-A-03-B-L8-2S-NN-NN-NN-FW is a unit in the HCT Multi Axis Drive Controllers series from Bosch Rexroth Indramat. It combines power conversion, axis supply, and central logic so several servo drives can run from a single cabinet slot. This arrangement lets the controller manage shared power distribution and centralized axis coordination in one place. In an automated line, it feeds the DC bus, supervises motion commands, and communicates with higher-level controls through an embedded PC based on the LX 800 platform and a SERCOS III master interface.
The controller accepts a three-phase mains range of 3 x AC 200...500 V, allowing use on international grids within the specified ±10% tolerance. From that input range, it generates a DC link that supports output frequencies up to 400 Hz, covering both standard induction motors and high-speed servo spindles. The common DC link supports multiple connected axes, so stable bus generation is important during acceleration and speed changes. Continuous supply for the primary X5.1 axis channel is rated at 35.0 A, matching the main drive current required by medium-frame motors. At 25 kW, it delivers nominal power to the DC bus while an internal choke limits ripple. If the link rises toward 900 V, the electronics initiate a safety shutdown, and an onboard braking module absorbs 100 kWs through a discrete 10.17 Ω resistor for controlled deceleration.
During steady operation, the unit draws 44.0 A from a three-phase AC 400 V line and dissipates 850 W of heat through an internal blower that delivers 310 m3/h of forced air. This cooling keeps the power stage and control electronics within their temperature limits while the enclosure remains at IP 20. The integrated brake resistor is rated at 5.00 kW, and a DC bus capacitor bank of 1.18 mF stabilizes the intermediate circuit so the drive can support short current peaks up to 37.5 kW without excessive voltage swing. The available encoder and probe connections allow feedback capture and position-related signal handling directly at the controller. With 32 digital inputs, 16 outputs, four encoder channels, and four probe inputs, the device supports coordinated multi-axis cycles without auxiliary I/O modules.
