Product Description:

Bosch Rexroth Indramat builds the CSH01.1C-S3-EN2-NNN-MD2-S1-S-NN-FW control section for the CSH Advanced Controllers series. Mounted on an IndraDrive power module, it executes drive-level motion logic, supervises encoder feedback, and exchanges real-time data with higher-level PLCs. The controller supports speed loops, position interpolation, and coordinated multi-axis motion, making it a core element in packaging lines, pick-and-place gantries, and printing presses. By combining communication, safe I/O, and local processing on one card, it helps reduce panel wiring while maintaining deterministic cycle timing across the drive stack.

The unit offers an analog monitor channel that can source 1 mA into loads up to 5 kΩ, and this path is commonly used with external meters or recorders for live process values. Each increment on that channel equals 19.5 mV/inc, which provides fine output resolution for signal monitoring. Command and diagnostic traffic moves over the optical ring of SERCOS III, allowing synchronized position updates with very low timing variation. Discrete sensors switch reliably because the digital input ON threshold is 15 V, while relays or indicator lamps can draw up to 500 mA per digital output without overloading the driver stage. These electrical limits apply to peripheral devices wired directly to the controller.

An internal encoder supply delivers 5 V to EnDat 2.1, 1 Vpp, or TTL feedback devices, eliminating the need for a separate sensor supply. The MD2 expansion mezzanine provides 16 transistor outputs for cam table functions or alarm routines. An RS-232 service connection is available at up to 115 kBaud, and cable lengths can reach 15 m for local serial access. This arrangement gives the controller a direct setup and diagnostic path when a network connection is not being used.
