Product Description:

The CSH01.2C-CO-ENS-EN1-CCD-NN-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive modular inverter, this section executes motion, current, and position loops for synchronous and asynchronous servo motors used on packaging lines, handling robots, and general factory automation. It hosts a SERCOS III backplane interface so that the inverter can exchange real-time process data with other drives and a higher-level PLC. By combining encoder evaluation, high-speed analog channels, and fieldbus connectivity, the unit acts as the central coordinator for one motor axis.

This control section provides one differential analog input with an impedance of 160 kΩ, preventing loading of delicate sensor circuits. Two analog outputs deliver reference values, and each channel can source up to 5 V at 1 mA for closed-loop setpoint generation. The current loop is updated every 62.5 µs, allowing tight torque regulation, while the position loop refreshes at 250 µs to maintain precise profiling at high speeds. For binary actuation, it offers protected low-side digital outputs, and each output can switch up to 0.5 A for relay coils, contactors, or signal lamps without external amplifiers.

System integration is handled through the master interface that supports CANopen / DeviceNet for diagnostics and parameter transfer when SERCOS is unavailable. The housing occupies only 103 mm in width, 241 mm in height, and 49.5 mm in depth, so multi-axis cabinets can meet tight enclosure requirements. Internal relay contacts rated at DC 24 V and 1 A let the controller forward status signals to safety chains or power interlocks without auxiliary hardware. The shallow housing also helps the control section fit into closely spaced modular drive arrangements.
