CSH02.1B-CC-EC-CN-L3-EM-NN-FW

The Bosch Rexroth Indramat CSH02.1B-CC-EC-CN-L3-EM-NN-FW is an advanced motion control unit in the CSH Advanced Controllers series, engineered for precise regulation of electrical motors. Designed as part of the Rexroth IndraDrive drive system, it features SERCOS III Master communication, a Multi-encoder primary interface option, and supports 2 analog outputs. This combination of high-speed communication and flexible encoding inputs positions the controller for demanding industrial automation applications, including coordinated multi-axis control and real-time feedback integration.

In its technical implementation, the control section integrates a Safe Torque Off safety module to prevent unintended motor startup and ensure operator protection. The multi-encoder interface accommodates sin-cos encoders (1 Vpp) with EnDat 2.1, 5 V-TTL square-wave encoders with reference track, and MSK/MSM motor encoder families, offering extensive compatibility. The SERCOS III Master link guarantees deterministic, low-latency data exchange with servo drives, while the dual analog outputs provide precise current or speed feedback signals.

Additional features include an encoder emulation interface that processes absolute (SSI) and incremental signals, all galvanically isolated to enhance signal integrity. The controller also offers a CANopen interface and supports user-installable firmware, ordered separately. Rated as category C3 under IEC 61800-3, it requires appropriate line filters to mitigate electromagnetic interference. Pulse width modulation frequencies of 4 kHz, 8 kHz, 12 kHz, and 16 kHz are supported, optimizing efficiency and reducing acoustic noise. In industrial environments, this controller delivers robust performance, high reliability, and seamless integration for sophisticated machine automation.
