Product Description:

The CSH01.1C-PL-ENS-EN2-CCD-S1-S-NN-FW is a single-axis controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into IndraDrive power sections and coordinates motion, safety, and feedback channels for electric drives used in packaging, printing, and handling systems. The module distributes logic power, interprets encoder signals, and manages safe I/O, allowing the drive to execute position, velocity, and torque loops without an external PLC. That combination makes the controller suitable for applications that need coordinated motion and integrated safety handling inside the drive platform.

The base board draws 7.5 W, so cabinet thermal planning can account for a low continuous load. All logic circuits are supplied from a 24 VDC feed, keeping the controller independent from the main bus voltage during standby. Inside the ENS option slot the module provides 6 W for its En2 interface, and that channel is terminated by a 35-ohm load that matches the differential line drivers used with BiSS or SSI encoders. The same En2 port sources up to 5.0 VDC, allowing direct power to external sensors while staying within extra-low-voltage limits. The port can deliver 350 mA of current, which is adequate for most multi-turn absolute encoders. For additional feedback, a standard encoder header supplies 6 W, and the Safety I/O rail reserves 1 W for light curtains or e-stops that report through safe logic inputs.

During power-up the controller can draw an inrush of 4 A for an interval of 100 ms; auxiliary supplies and fusing should tolerate that short surge without tripping. That brief surge is limited to startup, so normal operation does not place the same demand on the control supply. The ENS circuitry consumes 300 mA at runtime from its dedicated rail, which is regulated at 11.6 VDC to keep safety processors isolated from user I/O. After the initial inrush, steady-state consumption remains predictable because the optional feedback, encoder, and Safety I/O sections add only small fixed loads.
