Product Description:

The CSH01.1C-CO-ENS-EN2-MD1-S2-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into a compatible IndraDrive power module and supervises a single motor axis, processing fieldbus commands and real-time encoder feedback to regulate torque, speed, and position in automated packaging, printing, and handling machinery. By housing motion logic on the card itself, the unit frees the central PLC from high-frequency calculations and lets machine builders scale axis capability by selecting the appropriate drive stage without altering cabinet wiring.

Its base electronics draw just 7.5 W, yet the controller supports extensive field networking. The CANopen interface can manage up to 127 nodes and is cabled through a 5-pin spring terminal, while the DeviceNet port addresses 64 devices. Eight transistor outputs share a channel limit of 500 mA, and twelve digital inputs accept limit, probe, or start signals directly from sensors. A typical inrush of 4 A is seen when the 24 V control bus is connected, after which internal rails stabilize and communication, logic, and Safe Motion supervision become active.

The module distributes isolated encoder supplies. Channel EN2 delivers 5 V DC at 350 mA and supports load resistances down to 35 ohms, whereas channel ENS supplies 11.6 V DC at 500 mA for SinCos or Hiperface transducers. Capture inputs recognize reference edges with a maximum pulse width of 100 ms, ensuring position latches are accepted even at low shaft speeds. Safe Motion disables torque internally if monitored limits are exceeded, providing integrated functional safety. All circuitry operates from a cabinet supply of 24 V DC, allowing multiple axes to share the same low-voltage source while remaining galvanically separated from the DC link that feeds the power section.
