Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PB-ENS-NNN-NNN-S2-S-XP-FW control card for the CSH Advanced Controllers series. Installed in an IndraDrive chassis, it coordinates axis groups, manages safety I/O, and exchanges data over Profibus. By interpreting encoder feedback and scaling analog references, the board issues synchronized setpoints so servo inverters follow the commands required in packaging, printing, and material-handling lines.

The analog front end accepts differential inputs over a range of ±10 V, letting external controllers feed position or torque references without extra conditioning. Two output channels return a proportional voltage of 0 to +5 V for speed or tension feedback. Transistor drivers can source up to 500 mA to energize contactors or opto-isolators. The D-Sub 15 encoder port samples edges reliably up to 500 kHz, and a built-in 120-ohm termination is provided. At power-up the card draws 4 A of inrush current to charge its capacitors; steady operation requires only 7.5 W, keeping cabinet heat low.

The remaining supply paths support the safety circuit. The logic, interface, and safe motion blocks are all powered from a single DC 24 V source that can be paralleled with other IndraDrive modules. To limit bus disturbances, the initial surge is confined to a window of 100 ms; this short duration protects upstream relays when multiple controllers energize simultaneously. When safety functions such as STO or SS1 are commanded, the auxiliary terminals can deliver up to 1.6 A, ensuring that external relays and light-curtain feedback loops remain energized without overloading the primary logic regulators. Profibus communication is routed through a female D-Sub 9 connector with an additional repeater output rated at 75 mA, simplifying daisy-chain wiring across the machine.
