Product Description:

The CSH01.2C-PB-ENS-NNN-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Installed in an IndraDrive rack, the unit functions as the motion and communication brain for drives that require coordinated positioning, speed regulation, and integrated safety. In automated lines it receives set-points from higher-level PLCs, evaluates encoder feedback, and distributes bus data so that axes, sensors, and supervisory stations operate in a single deterministic cycle.

Encoder transducers connected to the board are powered by a regulated supply of 12 V DC, eliminating the need for an external sensor rail. Parameterization and diagnostics are performed over an engineering interface that is Ethernet-based, allowing standard TCP/IP tools during commissioning. Real-time command exchange with the host PLC uses PROFIBUS PB, a fieldbus chosen for its predictable cycle times in multi-axis environments. Network wiring terminates at a D-Sub, 9-pin, female connector integrated on the front panel, so shield continuity and strain relief are handled by standard PROFIBUS plugs. The driver stage exhibits an output impedance of 350 Ω, matching the characteristic line impedance to reduce reflections on long cable runs and maintain signal integrity.

For segment extension the internal repeater draws only 75 mA from the backplane and is energized by 5 V DC, keeping the module’s thermal load modest in tightly packed cabinets. Functional safety is addressed through Safety Technology I/O (S1); each input channel is monitored at 24 V, 3 mA, enabling reliable supervision of e-stop buttons and guard switches without stressing their contacts. A service port using RS232 remains available for firmware flashing or quick parameter uploads when network access is restricted.
