Product Description:

The CSH01.1C-ET-ENS-EN1-MEM-L2-S-NN-FW is a modular drive controller module manufactured by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. Designed for use inside IndraDrive servo inverters, this card handles axis control, fieldbus exchange, and safety monitoring within a compact slot. In automated production cells, it processes position loops and forwards encoder data so that high-performance drives follow programmed motion profiles with deterministic timing.

It draws a base power consumption of 7.5 W, minimizing internal heat generation while the logic circuits remain energized. Motion commands and diagnostic data are exchanged over the integrated Multi-Ethernet interface, allowing network protocols such as EtherNet/IP, PROFINET, and EtherCAT to be selected with parameters instead of hardware changes. Physical signaling conforms to the 100Base-TX standard, so standard Cat5e cabling carries real-time packets between the controller and higher-level PLCs. At power-up, the module momentarily demands an inrush of 4 A, a figure that guides fuse sizing and cabinet power-bus design. For personnel protection and machine compliance, the card delivers the certified Safe Torque Off function, which disables gate firing in the connected power stage without delaying energy removal.

Position feedback and simulated encoder signals are handled through additional front connectors. The emulation output can switch at up to 1 MHz, enabling high-resolution feedback to downstream devices that expect incremental or SSI timing. When a remote encoder adapter is required, the permissible emulation cable may extend to 40 m without degrading edge fidelity. Primary feedback supplies deliver 11.6 V at up to 500 mA for IndraDyn or HIPERFACE sensors, while the secondary channel provides 8 V and 250 mA for resolver or HSF transducers; an internal oscillator drives the resolver windings with 18.2 Vpp at 4 kHz so analog sine-cosine signals can be digitized without external electronics.
