Product Description:
Bosch Rexroth Indramat manufactures the CSH01.1C-ET-EN2-NNN-NNN-S2-S-NN-FW universal control section for IndraDrive systems in the CSH Advanced Controllers series. Serving as the motion-processing core, it links higher-level PLC commands to drive power stages and coordinates encoder feedback, analog references, and real-time Ethernet traffic within automated machinery. This arrangement allows one control section to manage signal handling, axis communication, and safety-related coordination in a compact drive platform.
The analog front end accepts command voltages over a bandwidth of 1.4 kHz, so the input channel can respond quickly to changing reference signals. A high input impedance of 160 kΩ minimizes loading of upstream signal sources, and conversion granularity of 2 mV/inc allows the control loop to resolve small setpoint changes. For actuator feedback, the output stage can source up to 1 mA while driving loads down to 5 kΩ, enabling direct interfacing with standard servo drives or process indicators. Encoder wiring is handled through a D-Sub 15-pin connector, and the interface supports EnDat 2.1, incremental 1 Vpp, or 5 V TTL formats so digital and analog encoders can be used on the same axis. A regulated 5 V supply is available on the connector to power the transducers.
Supplementing the analog channels, the module offers an output step size of 19.5 mV/inc for fine control of analog actuators. Network traffic passes through a Multi-Ethernet stack with two RJ45 ports running at 100Base-TX, which supports line, ring, or star topologies without extra switches. A single-line control panel supports local diagnostics, and relay contacts rated at DC 24 V, 1 A provide field-isolated signaling for brakes or contactors. The integrated Safe Motion option is certified to SIL2 / Cat. 3 PL d, allowing reduced-torque or safely limited speed modes without external safety relays.
