Product Description:

The CSH01.1C-PB-ENS-NNN-MD2-L2-S-NN-FW is a single-axis motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for IndraDrive platforms, it manages servo or spindle functions and coordinates auxiliary peripherals in automated machinery. The unit serves as the central command layer, translating fieldbus instructions into real-time drive signals and returning diagnostic data to the plant control system. Its integrated processing core executes position, velocity, and torque loops, while the pluggable option slots allow application-specific I/O expansion.

The controller operates its onboard logic and sensor circuitry from a dedicated 24 VDC supply, and its base power consumption is only 7.5 W, which helps limit cabinet heat generation. Field-level communication with PLCs is provided through a PROFIBUS interface, while service software connects through the integrated RS232 port. The controller provides 2 current-sourcing analog output channels that can feed process transducers or external drives. The primary encoder socket accepts IndraDyn, Hiperface, 1 Vss, or TTL feedback formats, allowing use with several common feedback types. A standard front control panel gives local parameter access, one relay contact with 1 N/O switching is available for auxiliary circuits, and the unit has an overall depth of 103 mm. The Option 3 slot contains a digital I/O plus SSI encoder module, while Option 2 is not equipped.

The housing width of 49.5 mm and height of 241 mm allow high-density mounting next to power inverters on DIN rails. One dedicated safety slot integrates the drive-level Safe Torque Off circuit, and this implementation meets SIL3 / Cat. 3 PL e functional safety requirements. The separate safety channel supports immediate torque isolation for emergency-stop functions without using the standard control interfaces. The narrow profile also leaves more room in the enclosure for adjacent drives or terminal blocks.
