Product Description:

The CSB02.1B-ET-EC-CN-L3-EM-NN-FW is a drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. This unit governs servo axes by processing feedback and network commands, then modulating a matched power section. In factory automation it links motion tasks to higher-level PLCs, providing closed-loop control for positioning, velocity, and torque functions. It is intended for cabinet installation alongside modular power inverters where space and clear cable routing are important.

It manages a single-axis workload and draws logic power from a DC 24 V control supply, isolating the control electronics from the main drive bus. Multi-protocol networking is built in, and the controller exposes a multi-Ethernet port that can be switched among EtherCAT, EtherNet/IP, PROFINET IO, and sercos III without additional hardware. When paired with HCS02, HCS03, HCS04, or HMS01 power sections, it can scale to different current classes while maintaining the integrated Safe Torque Off function for safe shutdown of torque output. A single-line display presents status codes locally, and a secondary CANopen channel supports diagnostic traffic independent of the main motion network.

Field wiring is straightforward. The CANopen service port is provided on a D-Sub 9-pin female connector, while feedback cloning or test rigs attach to a D-Sub 15-pin male emulation socket. That emulation output transmits incremental signals at 4 MHz, and it can mirror RS422, single-ended, or SSI formats through the multi-encoder interface for compatibility with existing control systems. The controller offers encoder emulation for legacy drives but omits a microSD slot, so parameter archives reside in the host PLC. The secondary interface on the front panel allows access to CANopen node ID and baud-rate settings without removing power.
