Product Description:

The CSH01.1C-PL-EN2-EN1-MEM-S1-S-NN-FW is a motion and logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. The board installs into an IndraDrive stack where it oversees servo axis coordination, feedback evaluation, and safety signal processing for automated conveyors, gantries, and packaging lines. By integrating resolver excitation, high-speed counting, and safe I/O supervision on one card, it reduces cabinet wiring and simplifies the control architecture in industrial automation cells. Its combined control and feedback functions allow the drive system to process motion commands and machine signals through one compact control platform.

Core electrical characteristics keep power demand and signal integrity predictable. The controller’s standby draw is only 7.5 W. On encoder channel EN1, it delivers a stabilized supply of 8 V DC while driving the resolver carrier at 4 kHz with a peak-to-peak amplitude of 18.2 Vpp. These values support accurate rotor angle conversion without external boosters. Encoder channel EN2 also supports distributed sensors, and its differential sense lines may extend up to 75 m before reaching the cabinet. The interface maintains proper logic levels with a 5.0 V DC reference, and returned pulses must remain below 100 ms to be accepted so unwanted signal stretching is avoided during rapid cycles.

Complementing the feedback stages, the EN2 port can source up to 350 mA, which is suitable for low-power optical encoders, while the drive as a whole can tolerate a startup surge of 4 A without tripping upstream protection. The MEM channel handles distributed latches over cable runs to 40 m, offering 20 mA push-pull drivers and a maximum toggling rate of 1 MHz for deterministic registration tasks. Sixteen parallel digital inputs and sixteen parallel digital outputs are available for standard machine signaling, which helps the controller interact directly with external sensors and actuators. For safety circuits, the card accepts 24 V logic at 3 mA and can switch outputs rated at 24 V / 0.5 A, enabling direct control of safe contactors or brakes without intermediate relays.
