Product Description:

The CSH01.1C-SE-NNN-NNN-MD2-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for use within the CSH Advanced Controllers series. Fitted to an IndraDrive power module, it executes motion sequences, supervises I/O, and relays diagnostic data to the plant PLC. In an industrial cell, the card translates program instructions into drive-level commands, letting the axis amplifier concentrate on torque generation while the controller maintains deterministic timing. This arrangement keeps command processing and drive control closely linked inside the axis system.

A baseline demand of 7.5 W powers the logic and communication circuits, and a momentary inrush of 4 A occurs when the backplane energizes, so supply breakers must tolerate that peak. The analog front end presents 160 kΩ of input resistance to minimize sensor loading, while the isolated output supplies reference levels up to 5 V / 1 mA for external amplifiers. Real-time data exchange travels over the SERCOS II fiber ring, giving cycle-synchronous access to parameters. Local machine wiring terminates on the plug-in MD2 module, which offers 16 digital inputs and 16 digital outputs; despite the channel count, the add-on draws only 1 W, which helps limit enclosure heating.

Each input channel is rated at 24 V / 3 mA, and the transistorized outputs can source up to 24 V / 0.5 A. The lines are organized as two input groups and four output groups to simplify common supply routing. The optical ring clocks at up to 16 MBaud, maintaining low jitter when the Option 3 Digital-I/O + SSI interface captures absolute encoder frames. Additional timing logic resides on the Se daughterboard, which dissipates 2 W and adds synchronous serial capability without expanding the slot footprint. For risk-reduced machinery, the integrated Safe Torque Off function disables drive power through certified solid-state paths, eliminating the need for separate contactor circuits.
