Product Description:

The CSH01.1C-SE-ENS-NNN-MD2-L1-S-NN-FW controller section is manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is mounted inside Rexroth drive systems to execute motion commands, manage feedback channels, and coordinate multiple axes through fiber-optic SERCOS networks. Within an automation cell, the unit operates as the central processing node that links a drive to the higher-level PLC, translating setpoint data into precise current loops while supervising safety interlocks during power-stage startup.

Real-time communication is handled over the SERCOS II interface, letting the module exchange process data and service channels within a minimum network period of 1000 µs. Inside that bus window, the drive executes a current control loop every 125 µs, allowing fast torque corrections during dynamic positioning. A serial diagnostic port supports parameter access at up to 115 kBaud, which is useful for setup with a laptop or service tool. Discrete automation signals are added through the built-in digital I/O and SSI expansion, and the analog stage can source 1 mA for external meters or transducers. These timing values and I/O features support close synchronization with motion profiles and connected field devices.

Sensor channels accept a differential range of ±10 V and are buffered by a high input impedance of 160 kΩ, which helps minimize loading on precision feedback elements. When a command reference is required, the module provides a regulated output of 5 V. Motion-ready relays are rated for 24 V DC, 1 A, enabling direct switching of contactors or brakes, and the integrated safety circuit applies a Starting Lockout to block unintended energizing of the power stage. The SSI encoder port supplies 24 V with 0.2 A available, supports clock frequencies up to 1000 kHz, and permits cable runs as long as 75 m for absolute position feedback devices.
