Product Description:

The Bosch Rexroth Indramat CSH01.2C-PL-EN1-NNN-CCD-S1-S-NN-FW is a motion and logic module within the CSH Advanced Controllers series. It serves as the primary control layer in multi-axis drive assemblies, linking servo drives, encoders, and safety terminals. By processing high-speed parallel data and supervising cross-communication, the unit coordinates precise positioning tasks and manages integrated safety functions across an automation cell. This arrangement lets the module coordinate motion commands and logic responses in the same control platform.

The controller exchanges cyclic process signals through a parallel interface routed to a D-Sub 37 connector. A bank of 16 digital inputs accepts position sensors or discrete status bits, while an equal number of isolated outputs can drive relays or interlocks without creating ground loops between field devices and the logic core. For upstream networking, it assumes the master role on an IEEE-compliant link, using the IEEE 802.3 standard to distribute setpoints or receive diagnostic data from subordinate nodes. Parallel data is then combined with the internal motion kernel before sub-millisecond command words are forwarded to the drive bus.

The feedback section accepts incremental or absolute data through a D-Sub 15 female socket. When an HSF or RSF encoder is used, its signals pass through an internal converter that resolves position to 12-bit precision; the converter is energized from a regulated DC 8 V rail and draws 250 mA during active sampling. Resolver feedback is also supported, with a 4 kHz carrier at 18.2 Vpp for coarse rotor-angle tracking in harsh environments. Safety Technology I/O lines are powered separately, and the dedicated rail can deliver up to 1.6 A so emergency-stop chains and light-curtain circuits remain energized even if field I/O power is lost. This separation helps maintain feedback availability during safety-related events.
