tweekzilla Posted September 11, 2012 Share Posted September 11, 2012 Hi All, I have two version of the Acc24E3: 1) Sinusoidal Feedback with 16-bit ADC Digital PWM 2) Sinusoidal Feedback with 16-bit ADCs Two Phase 16-bit DAC Is it possible to do step and direction on an Acc24E3 using either of the above options or do I need a Digital Feedback Mezzanine Board?

curtwilson Posted September 12, 2012 Share Posted September 12, 2012 In your first configuration, you can bring out pulse and direction either on the "Phase D" pins of the PWM amplifier connector, or on the T/U/V/W pins of the feedback board. To do the second, you must set Acc24E3.Chan[j].OutFlagD to 1 to enable the output buffers. (Note that this flag value is not saved, so you must set it after every power-on/reset. In the second configuration, you can also bring these signals out on the T/U/V/W pins of the feedback board by setting OutFlagD to 1. In all of these cases, the value in Acc24E3.Chan[j].Pfm determines the frequency and direction of the output. Bit 3 (value 8) of Acc24E3.Chan[j].OutputMode must be set to 1 to select PFM, not PWM, for this register. Link to comment Share on other sites More sharing options...
