Product Description:

The CSH01.2C-S3-ENS-MEM-CCD-L1-S-NN-FW controller belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in IndraDrive power sections, it executes motion logic, fieldbus exchange, and safety supervision for single-axis servo applications. By translating high-level PLC instructions into synchronized position, velocity, and torque references, the module shortens overall cycle time and simplifies cabinet wiring. Because all processing electronics are concentrated on this replaceable card, the control section can be updated without changing the entire drive assembly.

During operation, the card draws a base power consumption of 8.5 W, supplied from a chassis control line of DC 24 V. Real-time axis commands travel on a SERCOS III ring, while deterministic cross-communication between drives is handled by a separate IEEE 802.3 Master channel; both networks terminate on RJ-45 8-pin ports at the front edge. A single-line display allows quick verification of node numbers and diagnostic codes, and incremental or SSI encoder emulation can be activated from the same menu. The onboard relay contact, rated for DC 24 V at 1 A, lets the controller release a motor contactor when a safe stop is required. Encoder feedback wiring uses a 15-pin female D-Sub connector, and a dedicated 9-pin D-Sub carries safety I/O.

Fast local inputs tolerate frequencies up to 400 kHz, and the capture circuit recognizes individual pulses as narrow as 100 µs. The initial energization surge is limited to 4 A, allowing protective devices to be sized precisely. A safe stop uses Category 0 behavior, removing torque without delay. For sensor power, the controller provides a stabilized output of 11.6 V at 500 mA, keeping absolute and incremental transducers within their intended operating range. The combination of local high-speed inputs, integrated safety I/O, and onboard sensor supply supports direct connection of compatible feedback devices and safety circuits.
