Product Description:

The CSH01.2C-CO-ENS-MA1-CCD-L1-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for integration in multi-axis drive assemblies within the CSH Advanced Controllers series. Installed on an IndraDrive power module, it executes motion commands, processes encoder feedback, and enforces the built-in starting lockout for functional safety. The unit connects to upper-level PLCs, field sensors, and servo feedback devices for coordinated axis control in material handling, packaging, and general factory automation tasks. Its role is to provide the logic and interface layer between the power section and the surrounding machine network.

The module’s base circuitry draws only 8.5 W, so cabinet thermal load remains low even during continuous operation. Parameterization is completed through the engineering port, which uses an RJ-45 100Base-TX link that follows the IEEE 802.3 standard for Ethernet signaling. During power-up, the supply can momentarily reach an inrush of 4 A, a figure used when sizing upstream protection. The MA1 analog board provides two differential inputs and two outputs that accept or source signals in the ±10 V range, with conversion accuracy set by a 12-bit resolution. Additional serial access is available through an 8-pin MiniDIN RS-232 connector, which supports service diagnostics without occupying the fieldbus and keeps local access separate from the main control network.

The controller’s mechanical outline measures 103 mm in depth, 241 mm in height, and 49.5 mm in width, permitting high-density stacking on DIN rails inside narrow electrical enclosures. Master communication to external drives or I/O stations is handled over CANopen/DeviceNet, enabling deterministic bus cycles alongside digital encoder protocols such as IndraDyn, HIPERFACE, and 1 Vpp. The encoder interface supplies 11.6 V and up to 500 mA, so most incremental or absolute transducers can be powered directly from the card. This reduces the need for a separate auxiliary encoder supply in many cabinet layouts. The analog, serial, and Ethernet connections allow the control section to exchange commands, feedback, and service data through separate interfaces.
