Product Description:

The CSH01.1C-NN-ENS-EN2-MA1-S1-S-NN-FW is a control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. As a modular drive controller card, it coordinates axis feedback, discrete I/O, and analog processing inside IndraDrive stacks. It plugs into compatible power sections and provides the local control needed for coordinated axis groups and safety interlocks in automated machinery. This arrangement allows motion control, signal handling, and interface functions to remain within one compact drive assembly. It is well suited to systems that need centralized signal routing without adding separate interface hardware for each axis.

Base electronics draw 7.5 W, so cabinet thermal load stays low. The board exposes 11 digital inputs for limit switches or PLC status bits and 4 digital outputs for relay or transistor signaling; each output can source up to 500 mA per point. This mix of channels supports common machine signals such as home switches, interlocks, and simple actuator commands. Two probe inputs capture high-speed position events, and four safety-mode inputs support STO chains. The En2 feedback port powers its encoder with 5.0 V at up to 350 mA, giving incremental or absolute devices a stable supply. The MA1 module adds two analog inputs and two analog outputs, and the control section also provides filter and debounce logic for the discrete channels.

The separate ENS interface is intended for SinCos or Hiperface transducers and can deliver 11.6 V at 500 mA, which supports encoder operation over longer cable runs and keeps onboard identification electronics supplied. Analog front-end circuitry offers a 1000 kΩ input impedance to minimize sensor loading when external reference devices are connected. Both the A/D and D/A converters resolve signals at 5 mV/inc, which supports stable processing of command and feedback values in analog control loops. Output channels can source 10 mA references, making the card suitable for interface tasks that require low-level analog signaling. That combination allows the unit to exchange process signals for velocity or tension control while also managing encoder feedback, event capture, and safety-related inputs in the same multiaxis cabinet.
