Product Description:
The CSH01.1C-SE-ENS-MA1-MD1-L2-S-NN-FW is a drive controller command section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It occupies the left-hand slot of an IndraDrive power unit and supervises motor torque, velocity, and position loops in automated machinery. By exchanging real-time data with the power section and field devices, the unit coordinates axis motion, process timing, and the integrated safety channel used in modern industrial automation. Its modular design lets machine builders tailor I/O density and communication protocols while keeping cabinet space to a minimum.
Electrical loading at start-up is limited by a base inrush current of 4 A, and continuous electronics demand stays near 7.5 W, reducing heat inside the control cabinet. Fieldbus messaging is handled through SERCOS II; this interface carries cyclic setpoints and feedback, and its bandwidth scales up to 16 MBaud so multiple axes can be updated each millisecond. The controller can generate output pulses as long as 100 ms, a feature used for cam switching and probe functions. Two differential analog inputs and two analog outputs reside on the MA1 board, and the MD1 board contributes twelve 24 V digital inputs with eight transistor outputs that support task-synchronized machine sequencing.
Feedback wiring is carried on a 15-pin D-Sub female connector, allowing direct attachment of standard encoder cables without intermediate breakout. The analog channels work at 12 bits of resolution, giving adequate granularity for tension or pressure loops that depend on small voltage changes. When the controller drives solenoids or relays, each MD1 output can supply up to 24 V / 0.5 A, enough for most pneumatic valves. Functional safety is delivered by the certified Safe Torque Off circuit; its acknowledgment line accepts 24 V at 1 A while the control line draws only 3 mA.
