Product Description:

The CSH01.2C-SE-ENS-EN1-CCD-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Housed inside an IndraDrive power module, this board executes axis control algorithms, conditions I/O signals, and links the drive system with plant networks. Its role in industrial automation is to synchronize servo motion, handle safety-related inputs, and translate encoder feedback into deterministic position data for packaging, forming, and robotic work cells. It provides the computational layer between high-level PLC instruction sets and the power electronics that energize the motor, so speed, torque, and position commands are processed with minimal latency.

At the analog layer, the module offers an input resistance of 160 kΩ, allowing standard sensor transmitters to be read without excessive loading. A dedicated output stage can source reference signals up to 5 V for external devices such as torque followers. During normal operation, the board draws 8.5 W of base power from the attached supply, which helps limit cabinet heat rise. Control traffic to the drive is mediated through SERCOS II fiber-optic communication for cycle-synchronous data exchange. Local machine signals enter through digital inputs rated at 24 V, 3 mA, while actuators can be driven by transistor outputs rated at 24 V, 0.5 A. These channels let the controller monitor limit switches and analog references while switching external devices with predictable timing.

Additional communication versatility is supplied by the cross-link port, which complies with IEEE 802.3 over a 100Base-TX engineering interface and allows parameterization through standard Ethernet tools. Encoder channel 1 furnishes 12 V to resolvers or HSF sensors and accepts position data through a Standard Encoder Evaluation path, while a second port provides Resolver/HSF evaluation for redundant feedback. When the drive first energizes, an inrush of 4 A is expected before settling to nominal draw. Discrete machine states can be routed through an onboard relay rated at DC 24 V, 1 A, which adds galvanic isolation for safety chains. Serial diagnostics remain available through an RS-232 interface that reaches 115 kBaud. The embedded Safety Technology I/O resources support category-oriented stop and enable functions without external safety relays.
