Product Description:

The CSH01.3C-PL-ENS-NNN-CCD-S2-S-NN-FW is a drive controller from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. The unit functions as the command section inside an IndraDrive power stack, processing motion commands, feedback signals, and safety data for servo axes. Within an automated line, it receives encoder signals, translates them into velocity and torque references, and sends corresponding gate commands to the power electronics so that motors follow the programmed trajectory with deterministic timing.

The controller accepts two differential analog command channels spanning ±10 V, a range suited for proportional speed or torque references coming from PLC analog modules. Each channel is buffered by an input impedance of 160 kΩ, so external sources are not heavily loaded and signal fidelity remains high. Analog feedback can be re-transmitted through an output port rated at 1 mA, while a separate voltage output supplies a fixed 5 V level for sensor potentiometers or reference circuits. For discrete signaling, the logic stage offers seven fixed inputs plus four software-configurable lines, and these inputs expect 24 V signals for direct connection to standard industrial PNP proximity switches without intermediate relays.

Physical integration is simplified by a height of 241 mm, a depth of 103 mm, and a narrow 49.5 mm front width, allowing two controller sections to occupy the space of a single drive inverter in a control cabinet. Encoder slot one is equipped for IndraDyn, Hiperface, 1 Vpp, or TTL formats, while the second slot remains vacant for expansion. Diagnostic data moves outward on the RS232 service port, whereas high-speed peer exchange is handled by the Cross Communication Drive bus and a parallel master interface. Functional safety is embedded through Safe Motion (SIL2/Cat. 3 PL d), so axis-related stop or limited-speed functions can be executed without external safety relays.
