Product Description:

The CSH01.SE-ENS-NNN-NNN-S2-S-NN-FW is a control unit engineered by Bosch Rexroth Indramat for the CDB Control Units series. As a modular controller section, it coordinates drive functions and field communications in multi-axis automation cells. By processing feedback, command data, and safety signals, the unit serves as the central decision layer between higher-level PLCs and the power electronics that move servo axes in industrial machinery. This arrangement allows commands and operating data to pass between the machine controller and connected drive components.

The internal converter samples analog references at 12-bit resolution, providing the axis processor with 4,096 discrete counts across each voltage span and supporting precise torque or speed control. Real-time motion data moves across SERCOS II, with fiber-optic cables providing galvanic isolation and resistance to electrical noise over long cabinet runs. Each channel uses a differential signal swing of 1.0 Vpp, while the receiver has an input resistance of 120 ohms to minimize signal reflections on the communication ring. The encoder feedback port uses a 15-pin female D-Sub connector that carries excitation and incremental signals to the control logic. Status information appears on a single-line display that works with the standard control panel mounted on the front of the module. The display gives operators direct access to operating information without requiring a separate visualization device.

Auxiliary communication is provided by an RS-232 service port located on a female eight-pin Mini-DIN jack. The connected cable can reach 15 meters, and data transfers run at up to 115 kbaud for configuration tasks or controller backups. Encoders can draw up to 500 mA from the integrated 11.6 V DC supply, eliminating the need for external regulators. High-speed inputs accept transistor logic signals at frequencies up to 400 kHz, allowing the controller to record rapid marker pulses without losing input events. The Safe Motion package supervises velocity and position directly in the control hardware. It supports monitored stopping, limited-speed operation, and other certified motion functions without requiring external safety relays.
