Product Description:

The CSH01.3C-ET-ENS-MA1-CCD-S2-S-NN-FW control section is produced by Bosch Rexroth Indramat as a member of the CSH Advanced Controllers series. It is installed in modular drive stacks, where it executes motion profiles, manages fieldbus communication, and supports integrated safety functions for multi-axis machinery. By combining local processing with dedicated encoder and I/O ports, the unit coordinates drives, sensors, and actuators so automated lines can follow deterministic commands. Because the controller resides in the drive stack, signal paths between feedback devices and axis electronics remain short. It can serve as a local coordination point for motion commands, feedback evaluation, and axis-related I/O handling inside the same assembly.

For power distribution, the section connects to a DC 24 V logic rail and has a typical inrush current of 4 A when first energized. Once stabilized, the electronics draw a base load of 8.5 W. A dedicated encoder supply provides 11.6 V at up to 500 mA, allowing incremental or absolute sensors to operate without an external regulator. Additional internal domains support the Ethernet-TCP, CCD diagnostics, and MA1 analog I/O functions, and those internal loads do not change the external supply requirement. Separating the logic and encoder supplies helps maintain stable sensor operation while the main electronics handle communication and processing tasks, and it reduces the need for separate auxiliary regulation hardware in the cabinet.

The MA1 option offers two input channels and two output channels, and each channel uses 12-bit conversion for analog signal handling. Its conditioner can switch up to 16 kHz and reports over the Sercos bus with a minimum cycle time of 250 µs. Power use for this slice is limited to 2 W, while the embedded Ethernet circuitry remains within 2.2 W. The short bus update interval supports fast reaction to changing machine states. Safe Motion supervises limit monitoring, speed-dependent functions, and quick-stop logic, while the remaining internal timing functions are handled automatically during operation.
