Product Description:

The CSH01.1C-SE-EN1-EN2-MA1-S1-S-NN-FW is a compact motion-control card from Bosch Rexroth Indramat's CSH Advanced Controllers series. Installed in an IndraDrive modular rack, the card acts as the central processor that coordinates servo axes, handles fieldbus traffic, and links feedback devices to the drive inverter. Its role in industrial automation is to execute interpolated positioning, velocity loops, and synchronized cam profiles so that multi-axis machinery can meet cycle-time and accuracy requirements on assembly lines, packaging stations, and processing equipment. Because control, communication, and feedback processing are handled on one card, the drive system can coordinate multiple machine functions with consistent timing.

The card's base power draw is only 7.5 W, which helps minimize panel heat and supports dense stacking of additional option cards in compact cabinets. Motion commands and parameter data are exchanged over the SERCOS II fiber-optic ring, which provides real-time deterministic communication between the drive, PLC, and HMI. The fiber-optic link also avoids the electrical noise sensitivity associated with conventional copper communication wiring. The first encoder port supplies DC 8 V for resolvers or HSF transducers, and that interface accepts position data from Resolver and HSF devices so legacy motors can be used with newer feedback types. For analog process variables, the board accepts an input span of ±10 V, allowing an external tachometer or force sensor to feed the control loop. A matched 5 V reference is available on the analog output channel for drive-based setpoint generation or monitoring tasks.

The second feedback port furnishes DC 5 V for TTL-level encoders and supports the multi-protocol EnDat 2.1 / 1 Vpp / 5 V TTL interface, so absolute and incremental devices can be used on the same control platform. All analog inputs have a high impedance of 160 kOhm, which reduces loading errors when high-resistance sensors are connected. Safety technology I/O functions use a dedicated terminal block that accepts a safety input of 24 V / 3 mA. The same block provides a dual-channel safety output rated at 24 V / 0.5 A, and an auxiliary relay contact of DC 24 V / 1 A allows hardwired shutdown of external contactors. That output can be used in safe torque off chains or other hardwired shutdown paths within the drive system.
