Product Description:
The CSH02.5B-CC-EC-EM-NN-DA-NN-NW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it serves as the central processor that issues torque and position commands, handles encoder feedback, and manages machine sequencing for closed-loop axis control. By integrating motion control, general logic, and fieldbus communication on one board, the unit streamlines cabinet layouts and supports multi-axis coordination in industrial automation lines that use distributed drives and synchronized machine functions.
This controller communicates with drives and PLCs over a SERCOS III master interface, allowing deterministic cyclic data exchange for synchronized motion profiles. Analog monitoring channels digitize motor phase current with a resolution of 12-bit, while separate converters sample analog voltage feedback at 14-bit resolution to support precise current-loop tuning and fault detection. The internal 12 V rail can supply up to 500 mA to sensors and daughtercards, and a parallel 5 V rail can supply the same current to low-power logic devices. The controller also has 11 digital input channels for limit switches or probe triggers, and three optional card slots allow digital or analog I/O expansion for machine-specific requirements.
The emulation block delivers position data to legacy motion controllers at frequencies up to 1 MHz, sourcing differential signals rated for 20 mA per channel by using the RS422 standard. With an SSI cable limit of 75 m, absolute position feedback can be routed across large gantries without repeaters. The block also supports resolver reference frequencies of 8 kHz for hybrid feedback chains, and the board is not equipped with safety technology, so hardwired external circuits must provide emergency-stop functionality and related safe shutdown functions.
