Product Description:

The CSH01.3C-CO-ENS-EN2-CCD-L2-S-NN-FW is a compact motion-logic controller manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, the board manages axis coordination, handles field-level signals, and forwards real-time data to plant networks. Its role is to execute drive commands, safety interlocks, and I/O processing so that servo motors and actuators follow command sequences issued by higher-level PLCs. The controller serves as the logic layer inside the drive, keeping motion control tasks closely linked to the associated power section and feedback channels.

At a base consumption of 8.5 W, the module adds little thermal load while still providing 2 integrated analog outputs that can be mapped to velocity or torque setpoints. The controller also has 4 configurable I/Os for local status capture or handshake signals, and these lines can support simple machine interlocks or ready-state exchange. Fieldbus connectivity is provided through CANopen/DeviceNet, and the cross-communication bus complies with IEEE 802.3 for deterministic networking over the 100Base-TX engineering port. Serial maintenance is available through an RS-232 interface that supports cable lengths up to 15 m at 115 kbaud, and the Safe Torque Off function terminates on a D-Sub 9-pin connector.

The En2 channel delivers 5.0 V at 350 mA and supports feedback lines up to 75 m long when sense leads are used, making it suitable for larger gantry layouts. The Ens channel provides 11.6 V at 500 mA for resolvers or multi-turn encoders that require higher excitation. To protect upstream power supplies, the controller’s typical inrush current is limited to 4 A, and power-up stress is further limited by a 100 ms maximum inrush pulse. Separate encoder supplies let the controller support different feedback devices without requiring an external excitation module.
