Product Description:

The CSH01.1C-SE-EN2-EN1-EN1-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a modular drive rack, this unit handles motion commands and feedback evaluation for single-axis drive applications. It also provides integrated safety functions for industrial automation cells with synchronized servomotors, coordinated axes, and machine-level I/O.

Field communication is handled on a real-time optical ring through SERCOS II, and telegrams are exchanged at rates up to 16 MBaud for sub-millisecond cycle times across the drive network. At power-up, the control electronics draw an inrush of 4 A. Once initialized, they consume only 7.5 W, which eases thermal design inside compact cabinets and helps limit heat buildup around adjacent modules. A diagnostic analog channel offers a full-scale span of 5 V and a resolution of 19.5 mV/inc, enabling precise monitoring of drive variables during operation. An internal 8 V HSF rail supports secondary feedback, while the primary port supplies EnDat 2.1, 1 Vpp, or 5 V TTL encoders and can capture pulses up to 100 ms long. Resolver excitation is delivered at 18.2 Vpp and 4 kHz, and a secondary interface accepts two resolver or HSF signals for master-slave configurations. Safety Technology I/O is integrated on the board to separate standard motion commands from safety-related channels.

The feedback interface provides up to 350 mA to the main encoder so position data remain stable even over long cable runs. Safety inputs are evaluated at 24 V / 3 mA, while dual-channel safety outputs switch loads at 24 V / 0.5 A, allowing direct connection to contactors, gate switches, or light curtains. These interfaces support encoder supply, safety signaling, and direct connection of external protective devices without additional interface modules, which helps keep the rack layout compact and reduces extra wiring between the controller and the safety circuit.
