Product Description:

The CSH01.1C-CD-ENS-NNN-NNN-S1-S-NN-FW is a single-axis motion controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It operates as the command and feedback hub inside modular drive stacks, interpreting fieldbus traffic, processing encoder signals, and issuing real-time torque or velocity setpoints to the attached power section. By combining high-speed I/O with integrated safety terminals, the unit coordinates servo positioning tasks in packaging machinery, handling systems, and other automated cells that rely on deterministic motion sequences.

The analog front end presents an input impedance of 160 kOhm, so external transducers are not loaded by the controller. Outgoing analog signals are generated with a resolution of 19.5 mV/inc, allowing fine voltage scaling when the drive must follow a precise reference profile. Internal housekeeping draws only 7.5 W, which eases power-supply sizing in dense control cabinets. Each digital input switches to its logical on state at 15 V, matching common 24 V sensor rails while maintaining noise margins. Network traffic arrives through a D-Sub 9-pin connector that hosts the selectable DeviceNet or CANopen fieldbus module, enabling peer communication with PLCs and higher-level controllers without additional gateways.

For actuator loads, every sourcing output can deliver up to 500 mA, and this same current limit also applies to the encoder supply line, which is stabilized at 11.6 V. A start-up inrush of 4 A must be considered when sizing fuses and circuit breakers. Serial diagnostics is available over the integrated RS-232 port, which transmits at rates up to 115 kBaud for parameter cloning and service access. The relay channel switches up to 1 A, and the Safety Technology I/O block provides a 0.5 A output for force-guided contactors. Position transducers connect through a D-Sub 15 female interface that works with the standard encoder evaluation hardware, completing the feedback loop for closed-loop motion control.
