Product Description:
The CSH01.1C-SE-EN2-NNN-MEM-NN-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. This module serves as the motion and I/O coordinator inside a modular Rexroth drive stack, receiving SERCOS fiber-optic commands and generating incremental or SSI position feedback for the drive. Within an automation cell, it links higher-level PLCs to motor encoders while handling interpolation, safety monitoring, and field power sequencing for the associated power section.
Total internal loss is limited to 17.5 W, which is the amount of heat that must be removed by the cabinet ventilation system. During power-up, the board briefly draws an inrush of 4 A, so fusing and circuit breakers must accommodate that peak so the SERCOS ring remains stable. Each configurable analog output can source 5 V / 1 mA, providing a small-signal channel for torque or speed trim. Motion telegrams circulate with a minimum SERCOS cycle time of 1000 µs, allowing sub-millisecond position updates. Inside the En2 interface, the differential pair is terminated by 35 ohms, matching the impedance of short encoder cables and preventing reflection errors at high data rates.
The MEM timing block streams setpoint pulses up to 1 MHz, while its sink driver can deliver 20 mA to downstream counters without distortion. A form-C relay on the board can switch up to 30 V DC / 1 A, giving the control system a galvanically isolated channel for brake release or contactor feedback. Pulse outputs are restrained to a maximum width of 100 ms, so watchdog logic can detect line breaks quickly. The En2 supply rail is set at 5.0 V with a continuous capability of 350 mA, supporting EnDat 2.1, 1 Vpp, or 5 V TTL encoder formats without an external regulator.
