Product Description:

The CSH01.2C-PB-ENS-NNN-NNN-S1-S-NN-FW control section is supplied by Bosch Rexroth Indramat for IndraDrive control systems. Designed for IndraDrive servo amplifiers, the module serves as the central processor and fieldbus interface, translating higher-level PLC instructions into drive setpoints while forwarding high-resolution encoder data to the controller. It coordinates motion commands, feedback, and safety signals in automated machinery, allowing the connected drive to regulate motor operation in response to real-time control data.

During operation, the control section draws a base power consumption of 8.5 W, so internal heat dissipation remains low inside densely populated cabinets. Incoming supply surges are limited to an inrush current of 4 A with a pulse width of 100 ms, reducing stress on upstream fuses and power distribution components. The two differential analog inputs have an input resistance of 160 kΩ, preventing significant loading of connected sensor circuits, while the analog output provides 5 V / 1 mA for reference commands sent to external equipment. An Ethernet-based engineering interface supports online diagnostics and trace capture. The RS-232 service port supports cable runs up to 15 m at a maximum rate of 115 kbaud for configuration and diagnostic tasks.

Field connectivity centers on PROFIBUS, which is accessed through a 9-pin female D-Sub connector that links the unit directly to plant controllers without additional gateways. Incremental and SSI feedback devices connect to the 15-pin female D-Sub encoder port; these transducers receive an isolated supply of 11.6 VDC and up to 500 mA, supporting low-resistance cabling on extended machine axes. Separate I/O for functional safety is provided through another 9-pin socket. Its logic inputs are rated at 24 V / 3 mA, and the semiconductor output can switch up to 24 V / 0.5 A to initiate the safe torque off function immediately when required.
