Product Description:

The CSH01.2C-PB-EN2-MA1-CCD-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. As a modular controller, it installs next to power inverters and coordinates motion functions within automated machinery. The board handles command preprocessing, manages local diagnostics, and passes status data to higher-level supervisors. This arrangement separates axis regulation from plant sequencing while retaining deterministic exchange across the drive bus. The card is intended for applications that require continuous, dependable communication between drives, encoders, and integrated safety circuits.

Fieldbus connectivity is delivered through PROFIBUS-DP, allowing cyclic process data to be exchanged over the D-Sub 9-pin female connector. For drive-to-drive coordination, the unit operates as the cross-communication master and follows the IEEE 802.3 Ethernet framework. The engineering port supports 100Base-TX, so configuration software can upload or download settings at 100 Mbit/s without an external switch. Feedback devices attach through the EnDat 2.1 / 1 Vpp / 5 V TTL encoder interface, and the integrated 5 V sensor supply powers the transducer directly, which helps reduce extra wiring. This layout supports orderly signal routing between the control section, the encoder, and the surrounding drive hardware.

The MA1 option board adds analog processing capabilities. It provides 2 differential channels for voltage measurement, and each channel accepts a span of ±10 V and digitizes signals with 12 bits of resolution for tasks such as torque or pressure command capture. Two matching analog outputs share the same voltage window for drive reference generation, which allows external devices to exchange low-level control signals with the system. Functional safety is handled through Safety Technology I/O; inputs are rated at 24 V / 3 mA, while solid-state outputs can source up to 24 V / 0.5 A for actuator release or enable lines. These functions reduce the need for separate I/O cards in compact cabinets and keep related control signals on the same module.
