Product Description:

The CSH01.1C-NN-EN2-NNN-NNN-L1-S-NN-FW is an axis control unit manufactured by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed as the intelligence layer of an IndraDrive modular stack, it executes position, velocity, and torque loops for one servo or spindle while enforcing the Starting Lockout safety state before motion is enabled. By processing encoder feedback and issuing precise switching commands to the power section, the module maintains coordinated movement across automated presses, pick-and-place stations, and conveyor cells in general industrial automation.

The controller operates from a bus-side supply of DC 24 V, and this low-voltage line energizes logic circuits, internal relays, and the front-panel indicators. Overall power draw is limited to 7.5 W, so cabinet heat buildup remains minimal even in continuous duty. On initial energization, the unit draws an inrush current of 4 A, which is relevant when calculating fuse ratings and power-supply sizing. Motion tasks that rely on time-critical events can use the programmable pulse output, which accepts command widths up to 100 ms for triggering external brakes or valves. For incremental or absolute encoders that require sensor power, a stabilized output of 5 V is provided on connector X4.

Feedback signals enter through an interface that supports EnDat 2.1 / 1 Vpp / TTL, giving flexibility to pair the controller with high-resolution optical or magnetic encoders. Parameter downloads and diagnostics can be carried out over the RS-232 service port, which communicates at up to 115 kbaud when the cable length does not exceed 15 m. The unit mounts on a backplane and occupies only 103 mm of panel depth, while its 49.5 mm width and 241 mm height leave space for adjacent drive sections and ventilation channels.
