Product Description:

The CSH01.3C-SE-ENS-ENS-CCD-L2-S-NN-FW is a single-axis motion and I/O controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drive functions in automated machinery and manages the interaction between the control system, the power section, and the motor. It is intended for machines that require coordinated axis control and local I/O handling. The unit also provides closed-loop command processing, fieldbus connectivity, and safety monitoring during normal motion and safety-related stop conditions.

This controller supplies an analog output current of 1 mA or an analog output voltage of 5 V, so connected equipment can use either current-mode or voltage-mode feedback. Axis commands and diagnostic data move over SERCOS II, and a cross-communication setting assigns the unit as the network master for subordinate nodes. Machine switches and proximity devices are read through digital inputs rated at 24 V / 3 mA. Status lamps or contactors can be driven by digital outputs rated for up to 24 V / 0.5 A. These limits show the allowable field-wiring load without external relays or amplifiers.

For position feedback, both encoder ports accept the ENS format, and each port can source up to 500 mA at an encoder supply level of 11.6 V, which allows direct power for multi-turn absolute encoders without an auxiliary supply. An internal relay contact rated at 24 VDC and 1 A can isolate a brake release or interlock loop. Pulse-direction references such as high-resolution handwheels are captured through a TTL channel that registers edges up to 400 kHz. Safe Torque Off is included on the module, cutting the drive enable lines when a safety input is triggered, and a front-panel RS232 port supports local setup and service access without using the main network.
