Product Description:
The CSH01.1C-SE-EN2-MEM-MA1-L2-S-NN-FW is a single-axis motion controller from Bosch Rexroth Indramat in the CSH Advanced Controllers series. It is intended for cabinet-mounted drive systems where one control unit must manage feedback processing, field communication, and safety-related shutdown functions for a connected servo inverter. In automated machinery, the controller supports accurate position, speed, and torque control while also handling local signal exchange for coordinated axis operation.
Real-time communication is handled through SERCOS by way of the X20 transmit and X21 receive ports. The digital I/O section operates from DC 19-30 V and draws up to 1.1 A, which allows connected field devices to share the same supply source. The MEM card can generate position pulses at 1 MHz, supporting fast command updates for demanding motion sequences. Incremental or SSI output signals can be produced, and external encoders receive a regulated 5 V supply from the controller. Drive disabling is performed by the integrated Safe Torque Off function, which removes torque-producing power from the output stage while communication remains active.
A maintenance computer can connect through the RS-232 interface for parameter access and diagnostics without interrupting cyclic network traffic. High-resolution motor feedback can be accepted through EnDat 2.1, 1 Vpp, or TTL inputs, allowing the controller to process precise position information from several encoder types. The MA1 module adds two differential analog inputs scaled to ±10 V and two matching analog outputs for integration with external control equipment. Each of those analog channels uses 12-bit conversion to keep transmitted values consistent, and the base unit also includes an additional differential input together with two analog outputs for extended signal handling.
