Product Description:

The CSH01.3C-SE-ENS-EN2-CCD-S2-S-NN-FW is a modular drive controller section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power unit, it performs real-time command processing for multi-axis equipment by coordinating torque, speed, and position loops while supervising integrated safety functions. The module also links servo drives to plant-level networks and accepts both primary and secondary feedback devices to maintain deterministic motion control in industrial automation.

During operation, the controller draws a base power of 8.5 W, which indicates the internal consumption required for logic and encoder supplies. Axis data are exchanged over the SERCOS II fiber-optic ring, and the device can update drive parameters at a minimum Sercos cycle of 250 µs. Inside the control loop, current commands are recalculated every 62.5 µs, a rate that supports low torque ripple in high-bandwidth applications. Gate patterns for the attached power stage can be switched up to 16 kHz, which helps support smooth motor operation with low-inductance windings. When the unit is first energized, the DC-link filter charges with an inrush current of 4 A, so upstream protection must tolerate this brief surge.

Diagnostics are available through a 100Base-TX engineering port that accepts standard Ethernet cabling. The secondary encoder interface labeled EN2 can source up to 350 mA, while the primary channel provides 12 V for SinCos, HIPERFACE, or IndraDyn feedback. Integrated Safe Motion technology provides functions such as safe torque off, and the relay output is configured as 1 N/O contact for hard-wired status reporting. Cross-communication as a SERCOS III master passes synchronized position data to neighboring drives, and a dedicated 5 V rail powers incremental encoders without extra wiring.
