Product Description:
The CSH01.1C-NN-ENS-EN1-NNN-L2-S-NN-FW is a control section from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. Installed in modular drive stacks, this board handles signal conditioning and low-level logic so that servo inverters follow motion commands issued by a higher-level PLC. By combining analog, digital, and safety interfaces on one card, it supports machine integration in packaging, printing, and material-handling equipment. Its role is focused on control processing rather than power conversion, so it works alongside the main drive hardware instead of replacing it.
The controller can source analog feedback loops with an output current of 1 mA, a level that helps prevent overload on downstream velocity or torque inputs. Its corresponding analog reference is limited to 5 V, which matches common differential amplifier stages inside drive units. Internal electronics draw only 7.5 W of base power, helping keep cabinet heat rise low during normal operation. Each digital output channel can deliver up to 500 mA, which is sufficient for relay coils or optocouplers without added boosters. The EN1 high-speed feedback port supplies encoders with 250 mA at 8 V, helping incremental sensors maintain stable operation over longer cable runs. These electrical limits help the card distribute 24 Vdc control power across connected circuits without overloading the attached devices.
The ENS interface provides a reference voltage of 11.6 V for single-turn encoder heads, supporting the excitation needed by that feedback channel. At power-up, capacitors draw an inrush pulse that lasts no more than 100 ms, after which the input demand settles to its normal operating level. Communication with a host PC takes place over an RS-232 link that operates up to 115 kBaud for parameter access and diagnostics. Standard 24 Vdc logic is accepted on the supply terminals, and the Safe Torque Off circuit monitors that rail with a low sense current so the stop function can supervise the control voltage without requiring a separate external relay. This arrangement keeps the safety input tied directly to the controller supply used by the drive system.
