Product Description:
Bosch Rexroth Indramat’s CSH02.1B-ET-EC-NN-NN-NN-NN-FW controller belongs to the CSH Advanced Controllers series. Designed for multi-axis drive systems, this unit coordinates motion, handles feedback, and bridges higher-level networks in industrial automation cells. It fits into a modular drive platform and serves as the central processing board that distributes setpoint data to power sections while collecting encoder information for closed-loop regulation.
Its electrical loading is modest, with total internal demand peaking at 20.8 W, which supports cabinet layouts that rely on convection or simple fan trays. All cyclic traffic passes through a Multi-Ethernet backplane that follows the IEEE 802.3 physical layer, and the front port accepts sercos III, EtherCAT, EtherNet/IP, and PROFINET IO. Analog feedback from sine encoders is digitized with 12-bit resolution, while the associated input stage uses a 120-ohm termination to help prevent signal reflections. For pulse-based sensors, the capture circuitry tolerates pulse widths down to 1 ms and supports 12 V or 5 V rails, each sourcing 500 mA to connected encoder heads. Digital outputs can also deliver 500 mA when driving optocoupler boards or low-power relays.
High-speed applications benefit from an EC square-wave channel that records edge transitions up to 1000 kHz. A resolver carrier synthesized at 8 kHz is available for rugged rotor-reference devices, and the X32 analog monitor offers 14-bit voltage granularity for fine torque observation. The X35 current feedback path contains a 300-ohm shunt to translate motor phase current into a measurable voltage. A relay contact on the I/O cluster handles up to 1000 mA for interlocking tasks, and the Multi-Encoder Interface permits mixed use of TTL, HTL, and EnDat sensors within the same control system.
