Product Description:

The CSH01.2C-NN-ENS-ENS-CCD-L1-S-NN-FW controller belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. Installed in an IndraDrive inverter stack, it issues motion commands, processes feedback, and manages safety interlocks for multi-axis machines. By combining control logic with fast fieldbus links, the unit serves as the coordination layer between drive power sections and higher-level PLCs in automated assembly lines, packaging systems, and material-handling cells.

For local status processing, the acknowledgment input expects 24 V / 1 A. Two analog outputs are available, including a 1 mA current source and a 5 V voltage source for drive-level diagnostics or setpoint transfer. Cross-communication to neighboring drives occurs over the IEEE 802.3 physical layer through the Ethernet-based engineering port. The internal backplane can supply field I/O with up to 1.1 A, and the digital output group delivers 500 mA. At power-up, the module allows a startup window of 100 ms before the watchdog releases motion. The logic capture inputs accept edge frequencies up to 400 kHz without pulse loss.

During steady operation, the controller draws a typical 23.5 W, and its power stage can briefly accept an inrush of 4 A without tripping a fuse. Encoder channels are stabilized by an isolated supply of 11.6 V with a current limit of 500 mA, so absolute and incremental feedback devices receive clean power even when the combined load approaches 1000 mA. A starting-lockout input rated at 24 V and 3 mA lets external safety relays hold the drive disabled until machine guards are confirmed closed. When the analog, digital, and feedback outputs are active at the same time, the combined load stays within the controller's output current limits, which helps maintain voltage stability across the backplane and reduce thermal drift inside the housing.
