Hello,
I am working in MATLAB 2012a and using E60H incremental encoder (see Attached file 'E60HCatalog') with NI 9411 module
so I am acquiring data from the encoder and I could plot it. the plot is on the attached file (see Encoder_output) using this code:
daq.getVendors();
daq.getDevices();
s = daq.createSession('ni');
s.Rate=16000;
s.DurationInSeconds = 1.0
s.addAnalogInputChannel('cDAQ1Mod2','ai0','Voltage'); % NI 9234 vibration signal_1
s.addAnalogInputChannel('cDAQ1Mod2','ai1','Voltage'); % NI 9234 vibration signal_2
s.addCounterInputChannel('cDAQ1Mod1','ctr0','Position'); % NI 9411 Speed signal
[data,time] = s.startForeground();
%[data1,time1] = s.startForeground();
figure(1);plot(time) % ploting time
figure(2);plot(data(:,1)) % ploting vibration signal_1
figure(3);plot(data(:,2)) % ploting vibration signal_2
figure(4); plot(data(:,1)); hold on; plot(data(:,2),'r') % ploting both vibration signal_1 and vibration signal_2
figure(5);plot(data(:,3)) % ploting Speed signal
1- Really I am not sure what this output represent? (is it output A , B or Z).
and why the pules are increasing with the time and looking as stairs?
2- the most important is that I want to get and plot all encoder outputs, A, B, and Z. so how can I get and plot all of them?
3- how I can find the speed?
I really appreciate your help
thank you
