Product Description:

The CSH01.1C-PB-ENS-ENS-ENS-S2-S-NN-FW controller is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted inside an IndraDrive power section, it coordinates drive functions, feedback evaluation, and fieldbus communication in automated machinery. It interprets encoder signals, scales analog references, and exchanges data over Profibus, RS-232, and dedicated safety links so that multi-axis systems can execute synchronized motion, fault monitoring, and status reporting without separate interface hardware.

The two differential analog inputs present an impedance of 160 kΩ, which minimizes loading on upstream sensors. Each input converts voltage changes into position or speed commands at a resolution of 1.23 mV/inc. Outbound reference channels can drive actuators with loads up to 5 kΩ while issuing setpoints in steps of 19.5 mV/inc. During idle operation, the card draws only 7.5 W, which helps limit thermal rise inside the cabinet. Signals leave through a D-Sub 15 female encoder connector, and a separate D-Sub 9 female Profibus port supports cyclic data exchange. The RS-232 link operates over cable lengths up to 15 m, and each analog cycle uses a maximum pulse width of 100 ms to keep updates deterministic.

Digital control paths are rated for a continuous sink or source of 500 mA per point, with a combined group capacity of 1000 mA so connected logic devices can share one return path without overloading. The encoder supply delivers 12 V to incremental or absolute transducers. Startup current can reach 4 A, which should be considered when selecting circuit breakers. Safety signaling is routed through a D-Sub 9 female connector, and its semiconductor outputs provide 24 V at 0.5 A while dual relays can interrupt DC 24 V loads up to 1 A for emergency stop circuits.
