Product Description:

The motion control module CSH01.1C-PB-EN2-EN2-NNN-L1-S-NN-FW is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in IndraDrive systems, it acts as the control section that processes feedback, executes axis algorithms, and forwards commands to the associated power unit. Separate fieldbus and feedback connections let the controller manage motor position data while remaining linked to the higher-level control network. This separation allows the paired power section to focus on current delivery while the controller handles motion logic and signal evaluation. By hosting fieldbus and encoder interfaces in a plug-in card format, the unit streamlines cabinet layouts in multi-axis industrial automation.

The module exchanges cyclic data over a PROFIBUS network and refreshes its current loop every 125 µs, enabling tight torque regulation on high-performance drives. Internal logic draws a base requirement of 7.5 W from the control supply. Output stages can switch up to 8 kHz, a frequency that supports smooth control of permanent-magnet servo motors. During power-up, the electronics briefly demand an inrush of 4 A, and the short pulse is limited so standard cabinet fusing can tolerate the surge. A D-Sub 9-pin female connector labeled Pb carries the fieldbus signals, while an L1 connector in the same format routes local service communication and auxiliary inputs.

The card provides two encoder-supply rails; the first delivers 5.1 VDC without remote sensing and the second maintains 5.0 VDC when sense leads are used. EN2 can source up to 350 mA, and the discrete digital output block is rated for 500 mA of total sink current through optically isolated channels. When an incremental encoder is wired, the recommended line receiver presents a load of 35 ohms to support signal integrity. Control electronics are fed through the L1 pins at a nominal 24 VDC with a permitted continuous draw of 1.1 A. The initial energization window is limited to a 100 ms pulse so downstream supplies can stabilize before the axis enables are released.
