Product Description:

The CSH01.1C-PB-ENS-MEM-CCD-L1-S-NN-FW is a single-axis motion and safety controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Mounted in an IndraDrive cabinet slot, it generates setpoint data for servo inverters, acquires encoder signals, and exchanges diagnostics with the supervising PLC. Its role is to synchronize position, velocity, and torque loops while enforcing certified stop functions, making it a central component for pick-and-place lines, packaging stations, and material-handling axes.

The module exchanges cyclic process data over the fieldbus interface PROFIBUS-DP, so legacy PLC platforms can address it at deterministic update rates. For high-resolution feedback, it provides absolute position information in the SSI format, letting downstream drives accept 24-bit angle values without external converters. A built-in digital-to-analog stage supplies a reference of 5 V when an analog velocity or torque command is required. The encoder supply rail is held at 12 V to power inductive or optical feedback devices directly from the controller backplane. During operation, the logic section draws only 7.5 W, reducing cabinet heat and allowing passive ventilation in many installations.

At power-up, a surge limited to 4 A appears on the DC link, so line fuses and soft-start devices must account for this inrush peak. The controller can generate command pulses as long as 100 ms, enabling direct triggering of contactors or pulse-width-driven brakes, while serial maintenance access reaches 115 kBaud for rapid parameter uploads. Functional safety is implemented with dual channels that monitor 24 V circuitry, and acknowledgment is accepted when 1 A is sourced on the safe-ack line while the input side senses 3 mA at 24 V. A drive release is blocked until the system fulfills the Stop Category 0 starting lockout, ensuring mechanical energy is safely removed before restart.
