Product Description:
The CSH01.1C-SE-ENS-EN1-MD1-L2-S-NN-FW control section is built by Bosch Rexroth Indramat for use in the CSH Advanced Controllers series. Mounted on compatible drive bases, it acts as the central motion and I/O processor for one axis, translating fieldbus commands into power-stage signals for industrial automation equipment. By combining configurable encoder channels, analog conditioning, and digital safety features in a single plug-in module, the unit streamlines axis supervision and parameter handling in packaging, material-handling, and assembly machinery. Because the control electronics are concentrated in this section, the drive base can focus on power conversion while the plug-in module manages communication and signal processing.
On the signal side, each differential analog input can accept up to ±10 V; this range allows the card to sample position or torque references generated by external process controllers. The tracks present an input resistance of 160 kΩ, so connected sensors experience minimal loading and retain linear accuracy. Command values are returned through an analog output with a span of 5 V and a current capability of up to 1 mA, which is adequate for driving standard controller inputs without additional amplification. Discrete actuators such as contactors are addressed through eight transistor outputs, and every channel can deliver a continuous 500 mA sink current for direct connection of solenoid valves or indicator lamps. The integrated MD1 option board supplies twelve opto-isolated digital inputs and organizes all field wiring on spring terminals. This arrangement allows analog references, digital status signals, and switched loads to be handled from the same control section.
Real-time communication is handled by SERCOS II at 16 MBaud, keeping interpolation cycles brief during synchronized axis control. Two independent feedback ports accept ENS and EN1 encoder formats, powering the first sensor with 12 V and the second with 8 V, which eliminates the need for external supply modules. Functional safety is addressed through the integrated Safe Torque Off channel routed to a D-Sub 9 female connector, and when the contacts open, the power section is de-energized in under ten milliseconds. The communication and feedback connections are housed on the control section, keeping encoder supply and signal routing local to the axis module.
