Product Description:

The CSB02.1B-ET-EC-EP-L3-NN-NN-FW is a drive controller from the CSB Drive Controllers series produced by Bosch Rexroth Indramat. As a control unit, it manages torque, speed, and position loops for servo axes used in automated machinery and material-handling cells. By integrating feedback, safety, and network interfaces into one module, the product simplifies drive cabinet layouts and reduces setup time in industrial automation.

The controller processes analog feedback with 11-bit resolution on current inputs and handles voltage inputs at 13-bit, while its conversion bandwidth reaches 1.3 kHz. These figures show how accurately and how quickly the unit can translate sensor signals into control reactions. An additional analog output is provided at 24 mV/incr, enabling finely scaled command signals for external devices. Multi-turn or single-turn devices can be attached through a Multi-Encoder Interface, and a bank of 11 digital inputs accepts field signals; type A levels are recognized once they exceed 15 V. Two probe inputs capture position events, and their 4 µs minimum pulse width preserves timing integrity during high-speed measurements. The controller sources up to 500 mA on each digital output, enough to drive contactors or indicator lamps directly. A 300 Ω input resistance on current channels prevents loading of sensitive transducers, and relay contacts inside the unit carry up to 1 A when galvanic isolation is required.

Network traffic is handled by a Multi-Ethernet stack that supports 100Base-TX signaling over a single RJ-45, 8-pin connector, so the drive can switch between EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Safe Torque Off is implemented as certified STO, removing drive power through redundant channels instead of relying on software alone. A relay output rated at 1000 mA max supplies hardwired status to safety relays. Two programmable probe channels support precise event capture for synchronized motion tasks.
