Product Description:

The CSH01.1C-PL-EN1-NNN-MEM-L1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. This module installs into IndraDrive power units to execute positioning, velocity, and auxiliary logic for servo motors used in industrial automation cells, conveyors, and material-handling stations. It interprets commands from upper-level PLCs, evaluates encoder data, and issues enable or interlock signals to the drive, forming the core decision layer between machine sequencing and power electronics.

Five signal resources form the I/O foundation of the board. The analog command channel accepts input swings up to ±10 V, enabling proportional speed or torque references from external process controllers. Two reference outputs are available; one is limited to 1 mA so it can drive high-impedance measurement circuits, and the other is fixed at 5 V for detector excitation or logic thresholding. Internal consumption is restrained to 7.5 W, which eases cabinet thermal budgeting. On the discrete side, the module brings in 11 optically isolated digital inputs that can trigger homing, limit switch, or quick-stop functions. These values indicate the electrical limits that must be respected when wiring this controller to shop-floor sensors.

Additional subsystems extend motion feedback and safety. A resolver or HSF encoder is powered through an auxiliary line that supplies 8 VDC at up to 250 mA, ensuring stable sensor excitation during rapid axis cycles. The MEM interface can clock position data over runs as long as 40 m, while transfer rates reach 1 MHz to maintain fine interpolation. Four transistorized outputs, represented by the value 4, allow drive-ready, brake release, or external relay actuation. A D-Sub 37-pin PL port offers host-side cabling, and the built-in starting lockout with option L1 halts drive activation until the monitored circuits confirm a safe machine state.
