Product Description:

The CSH01.1C-CO-EN1-EN2-NNN-S1-S-NN-FW is a motion-control interface card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is mounted inside Rexroth drive racks to orchestrate axis positioning, execute encoder evaluation, and bridge field networks to the power section. By processing feedback from resolver and serial encoders and by exchanging deterministic data with higher-level PLCs, it issues drive commands that coordinate automated handling, packaging, and machining cells. These capabilities allow multi-axis machines to maintain repeatable trajectories and cycle times.

The controller supplies an analog input stage with an impedance of 160 kΩ, ensuring that external sensors do not load the measuring circuits. Its analog output channel is limited to 1 mA, sufficient for reference signals destined for drive inverters. Core electronics draw a base power of 7.5 W, so cabinet designers can size auxiliary supplies with minimal overhead. Field communication is handled through the dual-protocol bus stack; selecting CANopen/DeviceNet on the X60 spring-clamp terminal allows rapid integration with decentralized I/O. For rotor position feedback, the EN1 resolver interface excites the transducer at 4 kHz, enabling stable angle calculation even at low speed.

When all encoder and bus options are active the board’s configured consumption rises to 21.5 W, a value that guides thermal planning for densely populated drive bays. The EN1 channel provides an excitation rail of 8 VDC at up to 250 mA, while the secondary EN2 channel offers a separate 5 VDC line for devices that require EnDat 2.1, 1 Vpp, or 5 V TTL feedback. Safety Technology I/O is implemented through a D-Sub 9 Female connector; its inputs accept control signals at 24 V / 3 mA and the mirrored outputs can switch 24 V at 0.5 A, allowing the module to participate in hard-wired emergency-stop chains without additional relays.
