Product Description:

Bosch Rexroth Indramat manufactures the CSH01.1C-PL-EN1-EN2-NNN-S1-S-NN-FW controller within the CSH Advanced Controllers series. The module serves as a central processing layer inside multi-axis drive systems, executing position loops, managing encoder feedback, and passing deterministic commands to power stages. By combining motion coordination and integrated safety channels, the unit helps streamline cabinet layouts for packaging, handling, and assembly lines that require rapid cycle times and synchronized axes.

During steady operation, the electronics consume 7.5 W, yet power-up places a temporary 4 A load on the control supply that must be accounted for when sizing cabinet breakers. Axis commands are exchanged over a parallel interface, while the auxiliary serial port supports diagnostic traffic up to 115 kBaud. The primary En1 feedback connector energizes resolvers with DC 8 V / AC 18.2 Vpp at a carrier frequency of 4 kHz, allowing absolute rotor position capture. Sixteen high-speed, opto-isolated inputs, listed as 16 parallel digital inputs, can latch machine sensors with deterministic response, and the internal resolver/HSF converter streams position words directly to the motion kernel.

Secondary functions are handled on a separate channel that delivers 5.0 V to incremental or EnDat encoders and can source 350 mA without external boosters. The controller outputs synchronized drive data as 16 parallel digital outputs and captures fine position data through EnDat 2.1, 1 Vpp, or 5 V TTL signals to support mixed feedback topologies. Integrated Safety Technology I/O is routed through a D-Sub 9 female connector, where logic entries are read at 24 V / 3 mA and actuator commands are furnished at 24 V / 0.5 A for interlock relays. By housing both feedback supplies and safety levels in one compact card, the hardware reduces wiring density and separates high-energy drive conductors from low-level logic paths.
