Product Description:

The CSH01.1C-CO-EN2-ENS-MD1-S1-S-NN-FW is a control option card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted in an IndraDrive frame, the board manages servo feedback, cyclic fieldbus traffic, and fast safety-related signaling, allowing a single axis to be coordinated with a PLC or higher-level control. Its purpose in industrial automation is to link motion hardware to deterministic networks while processing encoder information and discrete machine states.

Base power consumption on this card is 7.5 W, so the host power supply only needs to handle a small thermal load. A fixed 124-ohm, 1%, 200 mW bus terminator is included to match the CANopen line impedance and reduce signal reflections. On that network, the controller can appear among up to 127 nodes and still exchange cyclic data within the standard bit-rate envelope. A second DeviceNet stack lets the same hardware coexist on as many as 64 nodes when that protocol is required. Supply rails are separated: the EN2 encoder interface electronics operate from 5 V ±5%, while the ENS channel for safety-rated encoders needs a stable 12 V feed. These independent domains prevent ripple on the logic rail from affecting position feedback accuracy.

The drive-side timing resources allow output pulses as wide as 100 ms, enabling latch, trigger, or step-direction sequences without external timers. Motion-related status can be sampled through 12 x 24 V digital inputs, while actuator commands are driven by 8 x 24 V sourcing outputs. The dedicated X41 D-Sub connector routes safe-torque-off signals with a 24 V, 3 mA input level and a 0.5 A output capacity for the internal safety chain. During power-up, the board draws a typical inrush of 4 A, so supply fusing and cabling must accommodate that transient. The board also supports EnDat 2.1, 1 Vpp, and TTL encoder options for deterministic axis control in compact machines.
