Product Description:

The CSH01.3C-PB-ENS-NNN-CCD-S2-S-NN-FW controller is manufactured by Bosch Rexroth Indramat and is part of the CSH Advanced Controllers series. It is designed to act as the primary command module inside multi-axis drive assemblies, processing I/O signals and coordinating motion profiles for industrial automation equipment such as packaging lines and material-handling stations. By integrating fieldbus communication, safety logic, and basic HMI functions into one slot-mounted unit, it simplifies cabinet layout and minimizes wiring.

Machine-level networking is handled through the integrated PROFIBUS-DP interface, which transfers process data at fixed update times through a D-Sub 9-pin female connector. Each of the two analog input channels presents 160 kΩ of input resistance, so sensors place minimal load on upstream circuits. The analog outputs are generated with a resolution of 19.5 mV/Inc, allowing fine voltage scaling when the controller feeds external actuators. Digital outputs can source up to 500 mA per channel for direct relay or lamp activation, and the encoder supply delivers a regulated 12 V through the D-Sub 15-pin socket to power TTL or SinCos feedback devices. A single-line display on the front panel supports quick parameter checks. The unit operates as the master on the cross-communication bus to synchronize neighboring drives.

Power-up behavior is characterized by an inrush current of 4 A that lasts about 100 ms, so cabinet fusing and contactors must be sized accordingly. For auxiliary switching tasks, the onboard relay can carry up to 1 A on its isolated contact, while safety output stages are limited to 0.5 A because they comply with the Safe Motion function that disables torque when a hazard is detected. The safety and Profibus networks are connected through additional D-Sub sockets, keeping high-current paths separate from signal wiring.
