Product Description:

The CSH01.1C-SE-ENS-MEM-NNN-S2-S-NN-FW is a single-axis controller card from Bosch Rexroth Indramat and is part of the CSH Advanced Controllers series. Designed to plug into IndraDrive units, it executes motion commands, interfaces with field networks, and supervises safe operating states. In automated cells, this board handles trajectory generation and feedback processing so servo drives can follow command profiles with the tight tolerances required in packaging, printing, and assembly machinery.

At idle, the electronics draw 7.5 W from the internal 24 V backplane, which helps limit cabinet heat. Command exchange with higher-level PLCs occurs through the SERCOS II interface, and this deterministic bus supports bandwidth up to 16 MBaud across fiber-optic rings. Integrated encoder evaluation is performed by a 12-bit A/D converter that samples the sinusoidal feedback channels, and its analog front end has a cutoff of 500 kHz to preserve signal fidelity at high spindle speeds. The encoder supply rail can deliver 500 mA, allowing incremental or absolute sensors with higher load to be powered directly from the board. During power-up, the module tolerates a typical inrush current of 4 A for a maximum pulse width of 100 ms without tripping fuses, and Safe Motion logic remains isolated from the main control path.

For position emulation, the MEM channel provides square-wave reference signals that mirror real axis movement. Its driver sources up to 20 mA and can toggle at 1 MHz, supporting high-resolution capture cards over cable runs reaching 40 m without signal boosters. The emulated outputs are powered from a dedicated 11.6 V rail so disturbances on the logic supply do not skew pulse timing. All safety inputs and outputs are referenced to a separate DC 24 V domain that hosts the Safe Motion circuitry, while the optical SERCOS medium maintains galvanic isolation between the machine and the supervisory network.
