Product Description:
The CSH01.1C-NN-EN2-NNN-NNN-S2-S-NN-FW is a plug-in motion logic controller card produced by Bosch Rexroth Indramat for modular drive stacks in the CSH Advanced Controllers series. Acting as the central processor for multi-axis machinery, it interprets encoder feedback, executes PLC sequences, and issues torque, position, and velocity commands to connected servo inverters, enabling coordinated motion in packaging lines, handling robots, and automated assembly stations. This arrangement allows one controller card to coordinate several machine functions from a single slot in the drive stack.
The module accepts differential analog command signals, and the input circuit presents an impedance of 160 kΩ with a tolerated span of ±10 V, so sensors are lightly loaded while bipolar references are handled directly. Discrete sensor lines are supported through the same logic level, and each digital input operates at 24 V while sinking 3 mA for direct connection to PNP proximity switches. Cabinet space is conserved by the narrow face width of 49.5 mm and a front-to-back depth of 103 mm, permitting dense side-by-side mounting inside drive racks. It also provides two buffered analog outputs rated at 1 mA source capability and centered on a 5 V full-scale signal for speed references to legacy drives.
On the actuator side, transistor outputs can switch up to 0.5 A for lamp stacks or small relays. Safety-related axes are monitored by the integrated Safe Motion (SIL2 / Cat. 3 PL d) circuitry, enabling certified stop and speed functions without external safety relays. Position feedback from motors is received through the primary encoder interface, which recognizes EnDat 2.1 / 1 Vpp / TTL signals and supports mixed-sensor installations. For compact vertical mounting, the board height of 241 mm aligns with standard IndraDrive power sections, while diagnostics can be accessed through a built-in RS232 port and an isolated relay contact rated at 1 A for drive-ready signaling.
