Product Description:
The CSH01.1C-PB-EN2-ENS-MA1-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Serving as the logic and communication core inside IndraDrive units, this module directs servo power stages. It also exchanges fieldbus data with higher-level PLCs for coordinated motion sequences in industrial automation. Because it operates as the main control layer inside the drive, it combines command handling, feedback processing, and communication functions in one section. This helps the drive respond to machine commands while maintaining organized data exchange with the rest of the control system.
The EN2 option supplies secondary encoder power and signal routing through a D-Sub 15-Pin receptacle. Internally, the EN2 lines are energized at 5.0 V and can deliver up to 350 mA, which is sufficient for most incremental or absolute transducers. The MA1 analog module offers two differential input channels and two voltage outputs; each path is digitized or generated with 12-bit resolution and operates across a ±10 V span, enabling closed-loop torque or process pressure control. Master communication to the drive is handled through PROFIBUS, and a D-Sub 9-pin female connector carries telegrams at a maximum bus rate of 12 MBaud for deterministic cycle times in multi-axis cells. For local diagnostics or setup, the integrated RS-232 port supports point-to-point transfers up to 115 kBaud, allowing parameter uploads without occupying the fieldbus.
Supplementary sensor power is available on the ENS socket at 12 V, so external temperature probes or reference switches can be fed directly from the control section. The S1 digital interface accepts 24 V control signals that draw only 3 mA, and it can drive actuators at a maximum of 24 V / 0.5 A, eliminating the need for external relays on small solenoids. For high-resolution position feedback, the X4 port accommodates EnDat 2.1 / 1 Vpp / TTL encoders, while the X8 port recognizes IndraDyn / Hiperface / 1 Vpp / TTL formats. This supports mixed-sensor architectures within the same machine and allows the control section to work with different feedback devices on a common platform.
