Product Description:

The CSH01.1C-NN-EN2-NNN-MA1-L1-S-NN-FW control section is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It serves as a plug-in axis controller for IndraDrive drive units. The module provides command processing, feedback handling, and field-level interfaces for industrial automation tasks that require coordinated position, velocity, or torque loops.

It draws a base power of 7.5 W, keeping internal logic consumption low inside a shared power rail. For discrete sensors and actuators, the digital I/O header accepts an auxiliary feed of DC 19 to 30 V, 1.1 A max so the board does not load the drive bus. The embedded EN2 encoder port distributes a regulated 5.0 V (with Sense) reference and can source up to 350 mA for external feedback devices. It supports the EnDat 2.1 / 1 Vpp / TTL signal formats for incremental or absolute position capture. Analog resources include one ±10 V base input, two 0–5 V base outputs, two differential ±10 V MA1 inputs, and two ±10 V MA1 outputs, allowing direct connection to torque, velocity, or process transducers. This configuration does not include master fieldbus communication, so real-time commands must arrive through the analog or encoder channels.

Resolution of 12 bit is implemented on both the MA1 input and output converters, yielding 4096 discrete steps for scaling command and feedback voltages. A front-edge service port exposes RS232 for setup and service access when fieldbus modules are absent. The on-board relay can switch loads up to DC 24 V / 1 A, suitable for motor contactors or hydraulic valves. Functional safety is limited to the Starting Lockout feature, which prevents unintended energization after power-up until an explicit enable signal is received. These I/O and control functions make the module suitable for multi-axis drive racks that require deterministic encoder capture and fine-resolution analog control.
