Product Description:
The CSH01.1C-PB-EN1-EN2-NNN-S1-S-NN-FW is an intelligent drive controller in the CSH Advanced Controllers series from Bosch Rexroth Indramat. Installed in modular servo drive racks, it supervises axis positioning, gathers encoder feedback, and exchanges real-time data with plant PLCs. By combining motion processing with integrated safety I/O, the unit serves as a compact command layer for packaging machines, gantry systems, and flexible machining centers. Its control role keeps feedback handling and network communication in one module, which helps coordinate multiple motor axes during synchronized machine motion.
This controller dissipates a base power of 7.5 W, easing cabinet cooling requirements in dense drive assemblies. Each of its two analog outputs can reach +5 V against a 5 kΩ load, and the analog output resolution is 19.5 mV/incr, enabling fine process setpoints. A dedicated digital output supplies 24 V / 0.5 A for relays or solenoid valves, so nearby actuators can be switched directly from the controller. The primary fieldbus connector supports PROFIBUS-DP, letting the drive share cyclic position, velocity, and diagnostic data with a master controller. Encoder channel 1 accepts resolver or HSF feedback energized by an 18.2 Vpp carrier at 4 kHz, while channel 2 provides a regulated 5 V supply to EnDat 2.1, 1 Vpp, or 5 V TTL encoders for redundant position verification.
Parameters can be accessed through an Ethernet engineering interface running at 100Base-TX, and a local RS-232 port is also available. On the PROFIBUS network, the unit operates at up to 12 MBaud, which matches common factory communication speeds for cyclic motion data. Machine safeguarding is handled by the integrated Safety Technology I/O, which supports safe stop commands within the control architecture. For auxiliary signaling, the onboard relay is rated at DC 30 V / 1 A, making it suitable for status lamps or interlock chains. The RS-232 connection supports local serial access for systems that still use that communication method.
