Product Description:

The CSH01.1C-CO-EN2-NNN-MEM-S2-S-NN-FW control section belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Mounted on an IndraDrive power module, it supervises positioning, velocity, and machine-level safety for a single servo axis in industrial automation cells. Its role is to convert network telegrams and local sensor signals into coordinated motion commands, allowing PLCs to manage drives through the same hardware layer that handles analog feedback, encoder data, and relay logic.

The analog input accepts signals up to ±10 V and is buffered by a high input resistance of 160 kΩ, which limits loading on connected transducers. For actuator feedback, the board supplies an analog output span of 0 to 5 V with a source capability of 1 mA, suitable for reference voltages to external devices. Digital outputs can switch loads that draw up to 500 mA, letting the controller energize contactors or signal towers directly. Motion parameters may be simulated through the encoder-emulation channel, which operates to a maximum carrier frequency of 1 MHz so high-resolution drives can be tested without a real motor. The unit is designed for single-axis operation and exchanges process data over CANopen or DeviceNet, simplifying integration into multi-vendor machine networks.

Two built-in encoder sockets support EnDat 2.1, 1 Vpp, and 5 V TTL formats while delivering up to 350 mA at a stabilized 5.0 VDC to the sensing head. A third port reproduces that position information on the emulation channel for downstream controllers. Field devices that cannot be driven from logic lines can be switched by the relay, rated at 30 VDC / 1 A, providing galvanic isolation from the electronics. The controller’s integrated Safe Motion technology monitors speed and position in real time, allowing machinery to meet safety requirements without separate hardware.
