Product Description:

The CSH01.1C-PL-ENS-MEM-MA1-S2-S-NN-FW is a compact control section built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted on an IndraDrive power stage, it serves as the real-time interface between higher-level PLCs and the drive inverter, executing interpolation, feedback conversion, and integrated safety functions required for coordinated multi-axis motion in automated production lines. The module packages signal conditioning, pulse processing, and user-selectable option boards in a single-slot form factor, reducing panel footprint while retaining deterministic control.

At its 5 V TTL input, the controller accepts position pulses up to 400 kHz, permitting direct capture of high-resolution external encoders. Those edges are converted by a 12-bit position counter, providing 4096 discrete steps per cycle before scaling to machine units. The encoder connector supplies 11.6 V at 500 mA to power absolute or incremental devices, and a startup inrush of 4 A must be considered when sizing the supply fuse. For conventional switches, the board offers 16 inputs on a parallel port, while the MA1 piggyback card adds two analog inputs and two analog outputs for precise torque or tension commands.

Complementing those functions, the MEM pulse channel can stream step sequences at up to 1 MHz, and the signals can be transmitted over cables as long as 40 m without additional line drivers. Individual pulses may be stretched to a maximum width of 100 ms, allowing synchronized hold functions during homing routines. Sixteen transistor digital outputs distribute status or trigger signals to actuators, and the integrated safety layer identified as Safe Motion keeps brakes engaged or speed limits enforced when the main control loop is interrupted. Encoder emulation can present both absolute and incremental formats to legacy drives, and the MA1 analog generation path supplies setpoints back to existing equipment.
