Product Description:

The CSH02.1B-CC-EC-NN-NN-NN-NN-FW is a motion-logic controller produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. In an automation cell, this unit manages axis coordination, cycle logic, and real-time feedback handling so connected drives can maintain precise torque, speed, and position. It operates between field communication networks and the drive power section, allowing deterministic synchronization across multi-axis machines.

The controller supplies two programmable voltage channels with a resolution of 24 mV/incr across a range of ±10 V, allowing fine analog reference signals for external actuators. Motion commands are distributed through a SERCOS III master interface, and the current loop refreshes every 62.5 µs so torque commands can react quickly to changing loads. Internal electronics draw from a DC 24 V control supply, which separates logic power from the main supply. The unit also accepts eleven digital inputs, while five additional lines can be used as configurable digital I/O for auxiliary functions such as gate control or fault reset. A multi-encoder interface supports incremental, absolute, and serial feedback formats, so one hardware platform can work with different motor feedback devices.

High-level data exchange runs on a 250 µs communication cycle, which stays aligned with the position loop for stable control timing. The controller also uses a 125 µs velocity control cycle, helping the cascaded loops respond consistently during dynamic motion. Two analog channels, listed as 2 analog outputs, can be reassigned to process variables when motion references are handled digitally. Three backplane bays provide up to 3 optional slots for added fieldbus or safety modules. An RJ-45 8-pin engineering port with 100Base-TX support allows direct Ethernet access for setup, diagnostics, and network integration.
