Product Description:
The CSH02.1B-ET-EC-EC-NN-EM-NN-FW is a compact motion and I/O controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In multi-axis automation cells, it coordinates servo drives, reads encoder feedback, and distributes real-time data between drives and PLCs to support deterministic positioning tasks. Output signals are also available as encoder emulation pulses, which let the unit duplicate incremental feedback for legacy drives.
The controller dissipates 17 W of base power, so cabinet ventilation must remove that heat during continuous operation. Its analog monitor channel has a resolution of 13-bit, allowing fine voltage scaling for process variables. Network traffic is handled through a Multi-Ethernet port set, giving access to EtherNet/IP, PROFINET, and SERCOS over the same connection. The EC interface group draws just 1.1 W from the internal supply, leaving power available for other options. Its sine encoder converter digitizes feedback with 12-bit accuracy. A second EC function can track high-frequency square-wave encoders, while two Multi-Encoder ports accept absolute or incremental transducers. The ET communications daughter card requires 2.7 W and uses the standard Ethernet link layer.
The high-speed square-wave limit of 1000 kHz supports position capture on fast rotary tables, and the EM option supports shielded cable runs up to 40 m so encoders can be mounted on distant axes. An internal budget of 6 W is allocated to power those external sensors, and that supply is protected by thermal monitoring. The ET board complies with IEEE 802.3 for connection to standard network switches. An additional 1.2 W is reserved for the EM circuitry, probe inputs recognize edges as narrow as 4 µs, and the onboard relay is rated for 1 × 10⁸ mechanical operations. Because no safety option is installed, machine safety must be implemented with external devices.
