Product Description:
The HCT02.1E-W0020-A-03-B-L8-2N-NN-NN-NN-FW belongs to the HCT Multi Axis Drive Controllers series manufactured by Bosch Rexroth Indramat. This multi-axis drive controller supplies coordinated power and motion commands to several servo and spindle drives, making it a central element in automated machining and assembly lines where synchronized positioning is required. By combining CNC control and drive coordination in one platform, it supports linked axis movement, contouring, and timed spindle operation across complex machine sequences. The unit is part of product line 02 in the HCT family.
The unit supports 3 axes, and each axis is routed through two independent channels so motion blocks can run concurrently, with four interpolating axes available per channel for contouring moves. The controller operates from a three-phase supply of 3 × AC 200–500 V, and the input can vary by ±10% without derating. Its power stage provides 20 kW of continuous output and is cleared for a fault current of 42 000 A rms. An integrated blower removes heat while the enclosure maintains an IP 20 rating. The feeding-type power module also forwards DC bus energy to downstream inverters, and version 1 includes two spindle interfaces for applications that use a main spindle and an auxiliary spindle under common timing.
The embedded automation platform includes 64 MB of CNC user memory for part programs, while 2 MB is reserved for PLC logic. Static data such as system parameters are stored in 44 MB of nonvolatile memory, and a standard CompactFlash slot provides removable data storage for machine files. For communication, the controller provides 8192 B In / 8192 B Out of deterministic fieldbus space, along with 8 digital inputs and 8 digital outputs for sub-millisecond reactions and 32 local inputs with 16 outputs for cabinet wiring. Motion and I/O cycles are managed by an Embedded PC, LX 800 master, and it can execute two PLC tasks in parallel. This arrangement keeps program handling, fieldbus exchange, and local signal processing on the same control platform during machine operation.
