Product Description:
The CSB02.1A-ET-EC-NN-L3-NN-NN-NW belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. As a compact single-axis drive controller, it coordinates current, velocity, and position loops for servo or induction motors used in automated machinery, packaging lines, and material-handling cells. Through its integrated communication stack, the unit bridges fieldbus traffic with feedback data so that higher-level PLCs can issue motion commands and receive status information in real time.
An analog channel with a resolution of 14-bit is provided for speed or torque reference signals, while one analog voltage input allows a continuous command profile to be applied. Network connectivity is handled by Multi-Ethernet hardware, allowing transitions between EtherCAT, PROFINET, or SERCOS without changing the base module. The controller has 7 digital inputs for limit switches, homing sensors, or user interlocks. On the Ethernet side, the controller supports 100Base-TX for deterministic 100 Mbit/s links to neighboring nodes. For functional safety, the drive can remove motor power internally through the certified Safe Torque Off channel.
The feedback interface uses a 15-pin D-Sub female connector and accepts multiple encoder formats through its multi-encoder interface, which simplifies retrofits from resolver systems to absolute feedback protocols. Dual ports with an 8-pin RJ-45 format support daisy-chain wiring or service access. Two optional slots can accept fieldbus couplers or additional I/O, and two probe inputs capture high-resolution position latches during camming tasks. One configurable I/O channel can be assigned as an extra input or output to match machine-specific logic. The relay contact inside the unit switches loads up to 30 V, and the auxiliary 24 V supply delivers an output current of 500 mA for encoder or sensor power.
