Product Description:

Bosch Rexroth Indramat builds the CSH02.1B-CC-EC-ET-SB-EC-NN-FW motion controller as part of the CSH Advanced Controllers series. The module serves as the control section within an IndraDrive system, translating PLC motion blocks into synchronized torque, speed, and position commands for connected servo inverters. It is installed in machinery such as cartoners, gantry loaders, and web presses where deterministic multi-axis coordination and integrated safety logic are required. By combining high-speed fieldbus communication with local encoder evaluation, the unit reduces cycle time and maintains precise axis alignment during continuous production on coordinated multi-axis equipment.

For field communication, the controller functions as a SERCOS III master, exchanging cyclic data with drives every 250 µs. The I/O panel provides 11 digital inputs for limit, home, or fault contacts, while 5 configurable digital I/O lines can be used either as outputs for relays or as additional sensor inputs. Process variables such as hydraulic pressure or analog follower commands are issued through 2 analog outputs with 12-bit resolution. Encoder ports share a 6 W power budget, allowing several high-resolution sensors to operate without separate external supplies. The Multi-Ethernet expansion bus links Profinet, EtherNet/IP, or EtherCAT devices, and three optional slots permit additional communication or I/O cards when needed.

The encoder interface provides 500 mA encoder supply current at 5 V and 12 V to support incremental TTL, absolute SSI, or HIPERFACE encoders without external power adapters. Differential signals can traverse up to 75 m over TTL cable, which is useful on tall gantry columns or remote rotary tables. Motion functions are protected through the Safe Motion Bus, enabling decentralized STO, SS1, and SLS states inside the drive chain. Two probe inputs capture position latches for print-mark or cut-to-length applications, and multi-encoder channels allow auxiliary feedback for gantry master/slave alignment during synchronized travel.
