Product Description:
The CSB02.1B-ET-EC-PB-NN-EM-NN-FW is a single-axis drive controller built by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. In automation cells it governs a servo or linear axis by conditioning feedback, executing motion profiles, and forwarding power-stage commands downstream. The module mounts in a control cabinet and coordinates with higher-level PLCs, delivering position, speed, and current loops that keep machinery accurate and responsive.
Control circuitry is energized from DC 24 V, aligning with common cabinet supplies and simplifying power distribution. The card supports an axis count of 1, so it dedicates its internal processor and feedback resources to a single motion channel. It presents 3 analog inputs for sensor references such as torque limits, while 2 analog outputs can retransmit process variables to external drives or displays with a resolution of 24 mV per increment. Discrete signaling is handled by 11 digital inputs and transistor drivers that source up to 500 mA; this combination allows fast start, stop, and diagnostic flags without auxiliary relays.
Network connectivity is oriented toward distributed automation. Motion data, parameters, and diagnostics move through Multi-Ethernet hardware that supports 100Base-TX signaling on an RJ-45, 8-pin jack, permitting standard-length Cat5e cabling. For legacy controllers, a dedicated PROFIBUS interface is also present. The multi-encoder port accepts absolute and incremental feedback and can emulate either format to downstream devices, easing retrofit work. Internal logic draws just 17 W, which limits heat buildup and allows dense stacking without forced airflow. No integrated safety functions are included, so machine-level protection must be realized with external devices.
