Product Description:

The CSB02.1B-ET-EC-PB-NN-NN-NN-AW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed inside modular IndraDrive systems, the unit executes closed-loop speed, position, and torque regulation for servo and synchronous motors used in packaging, handling, and machining equipment. Its electronics link motor feedback, local I/O, and higher-level PLC networks so motion commands, status data, diagnostic information, and axis coordination can pass through one compact module without requiring a separate interface card for each function.

The controller includes an integrated Multi-Encoder interface, which lets it read several encoder formats on the same axis without external adapters. It has 3 analog inputs, so temperature probes, load cells, or potentiometers can be sampled directly, and command values or process variables can be returned through 2 analog outputs that are isolated for noise immunity. Network traffic is handled by built-in Multi-Ethernet hardware, which supports real-time motion telegrams alongside standard TCP/IP service data, while 11 digital inputs operating on 24 V logic allow deterministic monitoring of switches, sensors, and interlocks within the control loop.

External feedback devices can draw up to 500 mA at 12 V, which helps low-impedance encoders remain stable during high-speed motion and reduces the need for an added supply module. Real-time telegrams travel over an Ethernet stack that supports SERCOS III, EtherCAT, EtherNet/IP, and PROFINET IO, allowing the same hardware to fit different plant communication standards without changing the control section. A separate fieldbus interface supports PROFIBUS, and the board uses a D-Sub 9-pin female connector plus an internal repeater that supplies 5 V at 75 mA to downstream bus segments. Five digital outputs, two current inputs, and twin probe inputs complete the I/O set and support edge-triggered position capture without additional interface cards.
