Product Description:

The CSH01.3C-ET-EN2-EN2-CCD-L2-S-NN-FW is a single-axis drive controller from Bosch Rexroth Indramat produced within the CSH Advanced Controllers series. It serves as the central control section for IndraDrive power units, translating high-level machine commands into coordinated torque and position profiles for servo and induction motors in automated cells, presses, and material-handling lines. By concentrating motion logic, field communication, and integrated safety in one compact module, the unit simplifies cabinet layouts and supports efficient system integration in industrial automation systems.

Its I/O layer provides two galvanically isolated analog channels that source up to 1 mA each at a fixed reference of 5 V, and every increment is quantized at 19.5 mV/inc for fine analog setpoint generation. The outputs can drive feedback or valve electronics with loads down to 5 kΩ without distortion. Discrete signaling is handled by eight transistor outputs that deliver a maximum continuous sink current of 0.5 A, which is suitable for solenoid or relay pilot duties. Higher-level data exchange is routed through the configurable Multi-Ethernet port, and the board accepts EtherNet/IP, PROFINET, EtherCAT, and TCP/IP services through a 100Base-TX interface with an RJ-45 eight-pin engineering jack. For synchronous drive-to-drive coordination, cross communication is executed over SERCOS III with deterministic cycle times.

Position feedback is accepted through independent EnDat 2.1, 1 Vpp, or 5 V TTL encoder ports for both primary and secondary channels, allowing dual-loop operation when mechanical compliance must be compensated. A standard control panel on the front face provides keypad access for diagnostics, while parameter uploads can also be completed over the RS232 service interface, which supports cable runs up to 15 m. Two form-C relays rated for 24 VDC at 1 A provide hard-wired status outputs to safety circuits. The integrated functional safety layer delivers Safe Torque Off, instantly removing drive energy without tripping the upstream supply when a stop category 0 signal is issued.
