Product Description:
The CSH01.1C-SE-ENS-EN2-MA1-S2-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in IndraDrive modular inverters, it supplies closed-loop motion commands and drive diagnostics for automated packaging, assembly, and material-handling stations. By combining high-speed processing with dedicated encoder inputs, the card acts as the central coordinator between the host PLC and individual servo amplifiers in applications that require deterministic position and velocity control.
This control section communicates with the drive stack over SERCOS, and its fastest network refresh uses a 1000 µs cycle time to support synchronized multi-axis moves. Internally, the torque regulators update on a 125 µs current loop, so the drive reacts quickly to load changes within one servo period. When energized but unloaded, the board has an idle draw of 7.5 W idle draw, which helps minimize cabinet heat. A built-in relay with one normally open contact can switch auxiliary actuators, while the MA1 mezzanine provides two differential analog inputs, two analog outputs, and 12-bit conversion accuracy. The certified Safe Motion package monitors encoder data and disables power channels when velocity, direction, or position limits are exceeded.
Two separate encoder channels widen the range of feedback devices. The auxiliary interface provides a 5 V auxiliary supply and accepts EnDat 2.1, 1 Vpp, or 5 V TTL signals for linear scales or secondary axes. The main motor port offers a 12 V motor encoder rail and supports IndraDyn, HIPERFACE, or 1 Vpp feedback for precise rotor position. The analog input stage uses 12-bit input resolution, while matching 12-bit outputs can drive proportional valves or reference transducers. For discrete automation tasks, the card provides four digital I/O lines that can be configured as inputs or outputs.
