Product Description:
The CSH01.1C-SE-ENS-MEM-MA1-L1-S-NN-FW is a motion-control main card released by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive systems, it coordinates axis commands, feedback, and safety interlocks so that servo drives follow programmed trajectories without drift. The unit connects directly to higher-level PLCs and synchronizes drive functions, making it a central component for multi-axis automation and machine tools that demand deterministic timing.
This controller communicates with drives through the SERCOS optical ring, which supports cyclic data exchange with microsecond-level jitter. For analog feedback, the base input range is ±10 V, and an expansion board adds 2 differential channels for additional process signals. Command voltages are issued through a native 5 V reference, while two supplementary analog outputs allow independent actuator adjustment. Internal logic and sensor power share a common field supply of DC 19-30 V, eliminating separate bus adapters. Position data can be rebroadcast over the emulation port; this port uses a 15-pin D-Sub and sends SSI-formatted pulses without an external power feed, simplifying connections to indexing tables or legacy counters.
The serial service channel operates on RS232 and is routed to an 8-pin mini-DIN so that service computers can adjust parameters offline. Encoder signals are reproduced as absolute and incremental formats, letting downstream devices choose between single-turn words or quadrature pulses; supported primary encoders include IndraDyn, HIPERFACE, and 1 Vpp sinusoidal types. When machine safety is required, the integrated Starting Lockout function disables drive enable lines through a dedicated 9-pin D-Sub control input and meets stop category 0 (EN 60204-1), so power is removed without controlled deceleration.
