Product Description:

The CSH01.3C-CO-NNN-MA1-CCD-NN-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It functions as the central motion processor in distributed drive platforms, generating the command signals that synchronize axes and field devices across modern automation lines. By combining high-speed control loops with fieldbus routing, the module replaces multiple stand-alone boards and simplifies cabinet layouts in packaging, material handling, and light machining cells where coordinated motion is required.

The controller draws only 8.5 W at idle, which helps reduce heat in compact panels. Within every torque update, it executes the current loop in 62.5 µs, and the embedded Ethernet service port supports 100Base-TX for parameter setup and diagnostics. During power-up, the supply can momentarily demand 4 A for 100 ms, so input fusing must accommodate that pulse. The controller supports a maximum switching frequency of 16 kHz, which helps produce smooth motor currents when low-inductance windings are used. A CCD network interface built on IEEE 802.3 handles line diagnostics, and separate CANopen and DeviceNet masters share internal bandwidth through the same scheduler.

Network density reaches 127 remote nodes on the CANopen bus and 64 on the DeviceNet side without additional repeaters. For analog feedback, the MA1 channel accepts a differential span of ±10 V and digitizes it with 12 bit resolution; the same resolution is available on its voltage-mode output path. Standard onboard terminals mirror that range for direct sensor connections, while digital command voltages are available from 0 to +5 V for compatible control inputs. Position interpolation closes in 250 µs, and velocity regulation follows every 125 µs. These response times support tightly synchronized motion in applications that require fast control updates and stable analog signal handling.
