Product Description:

The CSH01.1C-S3-ENS-EN2-EN2-L2-S-NN-FW is a single-axis motion and logic controller manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It occupies the command slot in modular IndraDrive platforms, translating machine-level instructions into synchronized torque and position commands for servo and spindle drives in automated production cells. Parameter adjustments are made by the standard single-line control panel on the front bezel. Its role in the modular drive system is to manage command processing, feedback evaluation, and communication between the machine control and the connected axis.

The unit has 4 combined I/O points that can be assigned to fast limit switches or simple status lamps. Each digital output is rated at 24 V / 0.5 A, allowing it to drive small contactors or opto-isolated inputs without relays. Motion profiles and diagnostics travel over the SERCOS III master interface, and the controller links to the drive stack through an RJ-45, 8-pin network plug that also transports real-time synchronization data. Primary feedback is accepted through the multi-protocol encoder port; it supplies 11.6 VDC at up to 500 mA and supports IndraDyn / HIPERFACE / 1 Vpp signal formats.

The safety layer is integrated rather than external. A Safe Torque Off circuit routes through a D-Sub 9 female connector and relies on a 24 V / 1 A contact and a 24 V, 3 mA pilot input to satisfy category stop requirements. The core protective function is Safe Torque Off, which disconnects gate signals to the power stage within microseconds. Secondary feedback can be wired in parallel; the port delivers 5.0 VDC at 350 mA and reads the EnDat 2.1 / 1 Vpp / 5 V TTL protocols for redundant position checking. An RS232 serial interface is provided on the lower edge of the housing for service access.
