Product Description:

The CSH01.1C-PL-ENS-NNN-MEM-S2-S-NN-FW is a drive-mounted control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is intended to coordinate motion commands, handle encoder feedback, and exchange process signals between IndraDrive power sections and higher-level PLCs in automated machinery. By combining position evaluation with programmable logic, the unit supports precise axis synchronization needed in conveying, converting, and assembly stations.

The module is powered from a logic rail of DC 24 V, and its startup surge is limited to 4 A, so power supply sizing must absorb this short inrush without tripping. All real-time setpoints are transferred through a Parallel Interface, eliminating bus latency when multiple axes share a common clock. Sixteen onboard digital input channels and sixteen digital output channels give direct access to sensors and actuators, and the input side accepts up to 16 discrete signals with a maximum pulse width of 100 ms. For parameter storage and high-speed recipe exchange, the MEM port drives a 1 MHz data stream over memory cables up to 40 m in length. The ENS encoder connector supplies 12 V to supported S1, M1, S2, or M2 feedback devices, while the SSI format is available for absolute position capture.

Functional safety is handled through a dedicated connector using a D-Sub 9-Pin Female interface. Each safe input is rated at 24 V / 3 mA, and every safe output can source up to 24 V / 0.5 A for interlock relays or contactors. The integrated Safe Motion functions allow drive-based STO, SS1, and other monitored stop functions without external relays. These safety circuits operate independently from the main control logic, so encoder power, memory communication, and the single-line front-panel display remain unaffected during a safety shutdown.
