Product Description:

The CSH01.1C-ET-EN2-NNN-MD1-S2-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It fits into IndraDrive modular drives and directs servo or linear axes in automated machinery. By providing processing power, fieldbus links, and functional safety on one compact card, it acts as the decision layer between higher-level PLCs and the connected power stage.

In normal operation, the card draws 7.5 W of base power, so cabinet heat dissipation remains low, yet a brief startup demand of 4 A must be supplied by the bus capacitors during inrush. Command exchange with drives and remote PLCs is handled through the Multi-Ethernet interface, supporting EtherCAT, PROFINET, or EtherNet/IP communication without changing hardware. Position feedback arrives through the EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface that is routed to a D-Sub 15 female connector; the channel provides 5.0 V at 350 mA to energize typical rotary or linear encoders. For time-critical sequences, the control section can generate output pulses up to 100 ms wide, which is useful for synchronizing pneumatic clamps or tool changers with axis movement.

The plug-in modules mounted on the control section are separately supplied so that their loads do not interfere with logic circuits. The EN2 feedback extension consumes 6 W, while the network-oriented ET option needs 2.2 W. The MD1 I/O slice draws 1 W yet provides 12 x 24 V digital inputs and 8 x 24 V sourcing outputs; each output can deliver 0.5 A for pilot valves or relays. Safe Motion functions supervise speed and position and, when limits are violated, activate a safety relay rated at 24 VDC, 1 A to cut power to external contactors. This hardware segregation keeps deterministic real-time control intact even when mixed signal, encoder, and safety channels are active in the same drive stack.
