Product Description:

The CSH01.1C-SE-ENS-NNN-MEM-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive servo systems, this module handles axis coordination, fieldbus exchanges, and local I/O processing for automated machinery such as packaging, printing, and material-handling lines. By combining motion functions and sequencing in one slot-mounted card, it simplifies cabinet layouts and supports deterministic command execution within distributed drive architectures.

The card supplies one differential analog input with an impedance of 160 kΩ, limiting loading errors when sensors deliver small signals. It has 2 configurable analog outputs for proportional speed or torque references. It also has 11 opto-isolated digital inputs for edge-triggered events, so a PLC can hand off mode selects and limit switches without extra expanders, while four transistor digital outputs return drive status to external indicators. Communication with the master controller occurs over the SERCOS interface, allowing cycle-synchronous data exchange. The L1 safety channel accepts a control signal of 24 V / 3 mA and executes a Category 0 stop that terminates power to the power stage without delay. A standard control panel and a standard encoder evaluation interface complete the local service and feedback functions.

The external wiring set uses a front-mounted 9-pin D-Sub connector for the L1 channel, and its stop loop is monitored by a starting lockout feature that prevents unintended restart after an emergency event. For absolute or incremental feedback simulation, the integrated MEM generator drives cables up to 40 m and reproduces signals at frequencies as high as 1 MHz so downstream drives or counters can be synchronized. The generator is fed from an encoder supply of 12 V, while a dedicated RS232 port supports service diagnostics.
