Product Description:

Bosch Rexroth Indramat's CSH01.1C-ET-ENS-NNN-MD2-L2-S-NN-FW control section belongs to the CSH Advanced Controllers series. This module is installed inside an IndraDrive compact drive to execute axis control, field-oriented regulation, and device-level safety in industrial automation lines. By combining network communication, feedback processing, and discrete I/O on one board, it lets machine builders integrate servo motors, external sensors, and supervisory PLC commands without additional interface cards, reducing panel space and wiring complexity.

The analog front end accepts differential signals in the range of ±10 V, permitting connection of transducers. For reference generation, the board sources a regulated 5 V at 1 mA output that can power small potentiometers. Each digital driver can deliver up to 24 V at 0.5 A to actuate contactors or lamps, while the MD2 section provides 16 digital inputs and an equal number of transistor outputs. All field terminals are consolidated on a 44-pin HD D-Sub, so a single cable carries the complete MD2 signal set. Option 3 adds digital I/O plus an SSI interface, and an RJ11 six-pin socket is dedicated to the serial channel. A relay on the board switches auxiliary loads with a 24 VDC, 1 A contact rating, and the STO function connects through a nine-pin female D-Sub plug.

The motion subsystem reads IndraDyn, Hiperface, 1 Vss, and TTL encoders and supplies the transducer with 11.6 V at up to 500 mA over the feedback connector. MultiEthernet support enables simultaneous protocols across the onboard 100Base-TX port, allowing the drive to share status data with plant networks. Functional safety is implemented through the certified Safe Torque Off circuit, which removes drive energy through hardware gating without affecting control logic. Dedicated STO and SSI connectors simplify separate cable routing away from the main power conductors.
