Product Description:

The CSH01.1C-PB-ENS-NNN-NNN-L1-S-NN-FW is a modular motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed to serve as the central processing card inside Rexroth drive stacks, this unit provides axis coordination, fieldbus connectivity, and user interaction for automated machinery. Its role in industrial automation is to translate high-level program commands into deterministic drive signals, enabling precise speed, position, and safety management across multi-axis systems.

Signal conditioning on the controller begins with an analog input range of ±10 V, terminated by an input impedance of 160 kOhm, so external transducers experience minimal loading. For closed-loop references, the board delivers an analog output of 5 V / 1 mA, which is suitable for common servo amplifier command inputs. Field communication with upper-level PLCs or HMIs is handled over PROFIBUS-DP, while a single-line display on the control panel allows local parameter checks. The electronics draw only 7.5 W during steady operation, supporting fanless cabinet layouts, and the encoder interface supplies 12 V to feedback devices without an auxiliary source. A safety acknowledge channel rated at 24 V / 1 A is present so external relays can reset the controller's integrated starting lockout function after a fault.

At power-up, the board accepts a base inrush of 4 A that can be sustained for a maximum pulse width of 100 ms, and sizing the upstream circuit breaker to these figures helps prevent nuisance trips. Control contacts inside the module can switch loads up to 24 V DC / 1 A, and its safety circuit monitors a logic level of 24 V / 3 mA to verify guard door or emergency-stop status before enabling motion. The starting lockout described above remains active until this low-current confirmation is met, ensuring drives remain disabled if wiring is open or shorted.
