Product Description:
The CSH02.1B-CC-EC-EM-L3-NN-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed on an IndraDrive power unit, it provides coordinated motion control, closed-loop regulation, and signal conditioning for industrial machines. The board interprets encoder feedback, computes torque setpoints, and distributes them to connected inverter stages so packaging cells, material-handling gantries, and processing stations can maintain precise position and speed profiles. It supports machine sequences that depend on synchronized speed regulation, position feedback evaluation, and responsive command processing during continuous operation. This arrangement allows one control section to manage motion functions that would otherwise require separate interface hardware. By consolidating these control duties into a single module, it helps reduce cabinet space in automated production.
Two differential analog inputs operate with a bandwidth of 1.3 kHz and are digitized at 14-bit resolution, enabling high-fidelity acquisition of pressure or tension references. The internal DAC generates command voltages in increments of 24 mV per increment, giving the drive fine setpoint granularity when external devices depend on analog command levels. This analog stage is useful when upstream sensors or control loops provide continuous reference signals rather than network-only commands. Base consumption is 17 W, which limits the control section's demand on the shared DC bus. A 5 V supply line delivers 500 mA to encoder heads, while eight transistor outputs each provide 500 mA for contactor coils or indicator lamps. Programmable limit outputs can switch an external relay for status signaling or interlock functions.
As a Sercos III master, the controller exchanges cyclic data with connected inverters, while the EM option adds an SSI interface that clocks position words at 1 MHz. The L3 interface supplies incremental encoder signals, consumes 1.0 W, and can source 350 mA on its 15-pin connector. Engineering access is through a 100Base-TX (IEEE 802.3u) link on an RJ-45 eight-pin jack, with a maximum cable run of 100 m to the programming workstation. The on-board relay can switch currents up to 1000 mA. The resolver channel drives a carrier at 8 kHz for legacy feedback devices. This mix of communication and feedback interfaces allows the controller to work with both newer networked axes and older feedback hardware.
