6. CEA DSM Irfu BMAC BMAC module is a digital indexer and microstep amplifier with integrated DSP controller. It can drive any bipolar stepper motor (4, 6 or 8 wires). Thanks to its smart processing unit, BMAC is suitable for both simple mono-axis applications and complex mutli-axis systems Features –2.5A stepper motor driver. open loop or closed loop control. –Optimized current management to minimize thermal losses. – Smart move functions. –Hardware and Software end-stops. User configurable. – Integrated sequencer. PLC-like functions. –DSP controller. – Brake driver (option). July 19th 2013Adelino GOMES6

8. CEA DSM Irfu Conclusion Work in progress The settings run well without any problem There is a problem with the reading by Streamdevice.  We are working with Midi Ingenierie to solve this issue, and they provide us an excellent support. Nevertheless, this should not prevent us from searching other solutions. July 19th 2013Adelino GOMES8
