Product Description:

The CSH01.1C-PL-EN2-NNN-MEM-L2-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It serves as the central control unit in modular drive systems, combining motion control with local safety logic so that servo axes, encoders, and plant-level networks can be coordinated from a single plug-in card. By inserting this controller into a compatible drive rack, the system can provide deterministic axis control, parameter handling, and real-time diagnostics without adding a standalone PLC. This arrangement keeps motion processing and safety-related control within the same platform.

The card measures 49.5 mm wide, 241 mm high, and 103 mm deep, allowing high-density mounting inside a Rexroth drive stack. It provides 2 analog outputs, and each channel sources up to 1 mA at a nominal 5 V level for tasks such as setpoint generation to external amplifiers. An internal EN2 interface supplies 5.0 V at 350 mA to power feedback devices that use EnDat 2.1, 1 Vpp, or TTL signaling. When encoder signals must be replicated for auxiliary equipment, the Option 3 module provides hardware-based encoder emulation, and high-speed command transfer is handled through a parallel master interface while setup and service functions remain accessible through an RS232 serial port.

For machine I/O, the PL section offers 16 digital inputs and 16 digital outputs that can be scanned or driven directly by the controller. Functional safety is integrated, and the controller supports Safe Torque Off with a rating of SIL3 / Cat. 3 PL e, allowing drive power to be removed through certified circuitry instead of external contactors. The available I/O, encoder connectivity, and communication channels allow the unit to manage motion tasks and safety-related signals in the same controller. This arrangement also lets the controller interface directly with status sensors, interlocks, and actuator signals in modular machinery without requiring separate I/O hardware for every axis section.
