Product Description:

The CSH01.1C-ET-EN1-NNN-MD1-NN-S-NN-FW is a programmable control section supplied by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive power unit, this module executes motion sequences, evaluates encoder feedback, and communicates with higher-level PLCs to synchronize axes in automated machinery. By combining fast digital I/O with integrated analog channels, it supplies the command logic that links servo drives to sensors, valves, and actuators in assembly lines, packaging equipment, and material-handling cells. This arrangement lets the controller manage local drive functions while still responding to machine-level coordination commands.

The control section has a base power demand of 7.5 W, with additional consumption assigned to the EN1 encoder interface and the ET communication board. An analog output provides a stable 5 V reference for speed or torque trim. Twelve digital inputs switch state when the on-level reaches 15 V, while eight digital outputs can switch loads up to 0.5 A each. Incoming analog values are sampled at 12-bit resolution, allowing finer setpoint scaling than coarse 8-bit devices. Resolver or HSF signals are excited at 4 kHz with 18.2 Vpp, and the EN1 section adds 6 W to the total demand.

For networked machines, the integrated fieldbus is selectable as Multi-Ethernet, letting the same hardware participate in different real-time Ethernet topologies. During power-up, the board tolerates an inrush of 4 A, and its pulse generator can issue command bursts as short as 100 ms. The MD1 add-on provides 12 additional digital inputs and eight further outputs while consuming only 1 W. Because the fieldbus and I/O functions reside in the same section, the controller can exchange status signals and motion commands without separate interface modules. This expansion supports extra sensors and control signals in compact multi-axis cabinets while keeping thermal loading predictable.
