Product Description:

The Bosch Rexroth Indramat CSH01.1C-CO-ENS-EN2-MA1-L2-S-NN-FW is a plug-in control section within the CSH Advanced Controllers series. Mounted on a compatible power module, it executes motion profiles, handles process feedback, and provides the electrical interfaces needed to connect sensors, actuators, and higher-level networks in automated assembly lines and material-handling systems. This module includes analog and fieldbus resources aimed at precise setpoint handling. Its control functions let the drive respond to external commands while maintaining coordinated operation with upstream machine control.

The analog section provides 2 inputs and 2 outputs. Each channel operates across a span of ±10 V, and conversion precision is fixed at 12 bit, enabling the drive to resolve small reference changes when regulating speed, pressure, or web tension. The input calibration aligns with the base analog requirement, so no external scaling resistors are necessary. A separate base output is limited to 0 to +5 V, which suits tachometers or indicator cards that cannot accept bipolar levels. These analog resources let the controller accept reference signals and return measured values to external devices without extra interface hardware. Networked control is managed through DeviceNet/CANopen, permitting cyclic data exchange and diagnostic messaging over the CAN physical layer already common in plant installations.

Digital signaling and service ports complete the interface set. Command lines are accepted at 24 V, 3 mA, while switching of solenoids or contactors is handled at 24 V, 0.5 A through solid-state outputs; the integrated relay accommodates 24 VDC at 1 A for isolated circuits. Service access is available through 100Base-TX Ethernet, and runs of up to 100 m can link the controller to a programming terminal. For legacy tools, an RS232 maintenance link supports 115 kBaud. Encoders can be powered directly with 11.6 VDC at 500 mA on the primary channel and 5.0 VDC at 350 mA on the secondary. Functional safety is achieved with the Safe Torque Off circuit, which disconnects drive energy without disrupting fieldbus communication.
