Product Description:
The CSB02.1A-ET-EC-EM-NN-NN-NN-FW is a compact drive controller produced by Bosch Rexroth Indramat and assigned to the CSB Drive Controllers series. It is installed in multi-axis automation cabinets to regulate servo and spindle power stages, interpret encoder feedback, and relay status information to higher-level PLCs. By integrating motion control, bus communication, and low-voltage power management in one module, this unit streamlines machine wiring and speeds setup in packaging, handling, and machining lines. Its compact format also suits centralized control layouts where several axes share common power infrastructure and networked supervision.
Power consumption remains at 17 W, so the module releases little heat inside the enclosure. All logic circuits are supplied from a regulated DC 24 V line; at power-up, the inrush current is less than 5 A and the associated surge lasts 1 ms, which helps protect upstream supplies. Position feedback is digitized by an EC converter with 12-bit resolution, balancing accuracy and processing speed. The 12 V encoder rail can deliver up to 500 mA, and the 5 V encoder supply supports the same current level for mixed sensor topologies. One ±10 V analog input is provided for velocity or torque references, while two probe inputs capture edge-precise position latches. Two optional slots allow add-on safety or I/O cards, and the encoder interface uses a 15-pin female D-Sub connection for quick replacement.
Control signals enter through 7 digital inputs, giving the axis immediate start, stop, and homing commands without network latency. Real-time communication follows the Ethernet physical layer defined by IEEE 802.3, and the controller natively exchanges cyclic data over Sercos III, EtherCAT, EtherNet/IP, and PROFINET IO. This combination allows synchronized motion data exchange with plant networks while still supporting direct hardwired control functions. Two internal probe channels synchronize capture events with these buses, allowing time-aligned position sampling during machine operation.
