Product Description:

The CSH01.1C-SE-EN1-NNN-MD2-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It is a plug-in automation module for IndraDrive power units that coordinates servo axes, collects discrete signals, and handles real-time bus communication inside automated machinery. By combining motion processing, encoder evaluation, and fieldbus routing on one card, it reduces the need for separate interface hardware and supports synchronized operation in packaging lines, machine tools, and material-handling systems. This arrangement helps keep cabinet layouts compact and reduces the number of additional interface modules around the drive system.

The EN1 feedback channel terminates at a 15-pin female D-Sub socket. It supplies 8 V DC for incremental encoders and a 18.2 Vpp carrier for resolver windings, while the selectable HSF or resolver mode allows the drive to process either digital high-speed feedback or analog resolver signals. Network integration is handled through the SERCOS master interface over fiber-optic cable, providing synchronous communication for multi-axis platforms. An RS-232 port supports service connections up to 15 m, and the housing measures 241 × 49.5 × 103 mm to remain within standard drive footprints in compact control cabinets.

The MD2 section offers 2 x 8 optically isolated digital inputs and routes sixteen transistor outputs through a 44-pin high-density D-Sub connector arranged in four groups of four. Fast position latching can be linked over the SSI channel, which terminates on a 6-pin RJ12 socket and is powered by 24 V so connected sensors can draw supply directly from the board. Input changes propagate across the SERCOS ring in one millisecond, while the outputs can drive 24 V contactors or status lamps. SSI devices can be placed up to 40 m from the controller, and the RS-232 link remains stable to 15 m without signal repeaters, which supports flexible placement of connected devices within the machine.
