Product Description:

The CSH01.1C-PL-ENS-EN2-MA1-L1-S-NN-FW is a single-axis motion controller module produced by Bosch Rexroth Indramat and included in the CSH Advanced Controllers series. It plugs into a compatible drive inverter and executes position, velocity, and torque commands for servo motors in automated machinery. By combining field logic, encoder support, and analog processing on one board, the unit provides deterministic control inside cabinets where space and power budgets are limited. It is intended for installations that need compact motion coordination together with direct access to local I/O and feedback channels.

At idle, the module draws 7.5 W from the internal DC bus, and the initial energizing event is limited to 4 A of inrush current, so supply sizing can follow standard 24 V cabinet conventions. Command data reach the board through a Parallel Interface, while discrete machine signals are handled by a programmable bank of 16 In / 16 Out lines on the PL connector. The MA1 channel provides 2 Differential analog inputs for noise-resistant feedback such as torque potentiometers, and a 12-bit successive-approximation converter provides 12 Bit resolution for signal conversion and scaling. The same MA1 section also offers two analog outputs so the controller can feed reference voltages to external actuators or data loggers. Because the digital and analog functions are grouped on the same board, wiring between the inverter and the control section remains compact.

Separate encoder supplies stabilize sensor loops and keep feedback devices on dedicated auxiliary rails. Channel EN2 delivers 5.0 V at up to 350 mA, whereas the ENS rail supplies 500 mA at 11.6 V for transducers that require a higher bias. For safety acknowledgments, the L1 terminal furnishes DC 24 V / 1 A, and it recognizes return pulses drawn at only 3 mA. The MA1 input and output stages both operate across a ±10 V span, giving equal headroom for bipolar process signals. Pulse outputs from the controller can be stretched to 100 ms, which suits drives that need a longer latch window during homing.
