Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PL-EN1-NNN-NNN-S1-S-NN-FW, a control section in the CSH Advanced Controllers series. The unit serves as the logic and I/O layer inside IndraDrive modular drive assemblies, translating sensor feedback and command signals into actionable drive directives for automated machinery. Its compact format and dedicated analog, digital, and safety channels allow coordinated axis control in packaging, printing, and material-handling installations. This arrangement allows the control section to manage signal processing and interface tasks while the associated drive hardware handles power conversion for the motor.

The controller accepts an analog command span of ±10 V, and its input circuitry presents 160 kΩ of impedance, which helps limit loading on upstream motion controllers. When feedback or reference signals must be retransmitted, the module supplies a 0 to +5 V analog output range. A base consumption of 7.5 W keeps cabinet thermal rise low, while a momentary inrush of 4 A must be considered for fuse and power-bus sizing. For position feedback, it evaluates resolver and HSF formats; the resolver channel excites the transducer with 18.2 Vpp at 4 kHz. Command data can also reach the board over the parallel interface, and sixteen discrete inputs plus sixteen outputs are available through logic-level connectors. The EN1 port uses a D-Sub 15 female socket that groups most real-time I/O functions. This combination supports direct integration with external control devices and machine-level signaling without requiring separate interface hardware for every basic command path.

Dedicated safety circuitry on the CSH01 section is implemented through the Safety Technology I/O option. All risk-related wiring terminates on a D-Sub 9 Female connector, separating it from standard process lines. The safety inputs are rated at 24 V / 3 mA, enabling direct connection to light curtains or emergency stop buttons, while the safety outputs can source up to 24 V / 0.5 A for contactor coils or status lamps. The matching parallel I/O count of 16 channels per side remains unaffected by the safety layer, so standard machine signaling can remain available alongside the dedicated safety functions. This separation helps keep protective circuits distinct from routine control wiring and simplifies signal organization inside the drive assembly.
