Product Description:

The CSH01.1C-SE-EN2-NNN-NNN-L2-S-XP-FW is a plug-in control section manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. When combined with an IndraDrive power section, it forms a compact drive that performs axis regulation, fieldbus communication, and safety monitoring for industrial automation lines. By generating command values and processing feedback in real time, the module enables coordinated positioning and speed control for servo motors, actuators, and machine subsystems across packaging, handling, and processing equipment.

Its primary fieldbus interface is SERCOS II, allowing deterministic cyclic data exchange with PLC supervisors. Two differential analog outputs supply reference signals; each channel offers a resolution of 19.5 mV/inc and can source up to 1 mA, while the output swing is stabilized at 5 V for drive or sensor interfacing. Internal electronics draw only 7.5 W of base power, conserving cabinet energy budgets, and a separate digital I/O rail can deliver 1.1 A to external limit switches or proximity sensors. Additional encoder power rails furnish 5.0 V at 350 mA, and the EN2 option dissipates 6 W when activated, matched to a minimum 35 Ω load.

Safety and diagnostic resources are integrated rather than added externally. The controller supports the certified Safe Torque Off function through a 9-pin female D-Sub safety connector, eliminating residual motion when the channel is triggered. For high-resolution feedback, the EN2 socket reads incremental and absolute signals that comply with the EnDat 2.1 encoder standard, while service access is provided through a 100Base-TX Ethernet port on an 8-pin RJ-45. These interfaces let service software download parameters and capture trace data without interrupting the real-time SERCOS bus.
