Product Description:

The CSH01.1C-SE-ENS-EN1-MD2-L2-S-NN-FW is a single-axis motion and logic controller produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It coordinates servo drives and peripheral devices in automated assembly lines, packaging stations, and material-handling cells. By combining fieldbus communication, encoder processing, and expandable digital I/O on one compact board, the unit serves as the central command layer that schedules motion profiles, gathers feedback, and issues real-time control signals to the drive train.

The controller draws a base power of 7.5 W, so cabinet power planning can be completed without heavy derating allowances. Its expansion card provides 16 digital inputs and 16 digital outputs through the Digital I/O and SSI option, allowing position latches and cam switches to share one module. Each input sinks 3 mA, while each output sources up to 0.5 A for pilot valves or contactors. The integrated fieldbus is SERCOS II, and the optical ring can be energized safely because the electronics tolerate an inrush of 4 A at power-up. The primary encoder interface is ENS, which supports SinCos feedback used by IndraDrive motors.

Pulse-generation capability includes a maximum output width of 100 ms, permitting axis-specific homing or probe functions without external timers. The encoder supply rails are separated, with the primary channel providing 12 V to the encoder and the secondary channel supplying Resolver/HSF feedback with DC 8 V. For resolver support, the board delivers an excitation carrier of AC 18.2 Vpp, enabling differential pickup at high rotational speeds. When a multi-axis network is required, the control bus can transmit telegrams at 16 MBaud, which helps reduce cycle time in tightly synchronized position loops.
