Reading a variable from drive is easily accomplished by using SimpleMotion V2 function smRead1Parameter, smRead2Parameters or smRead3Parameters. Usage is looks like:
//read raw value of current smint32 readout; smRead1Parameter( handle, nodeAddress, SMP_ACTUAL_TORQUE, &readout );
This C++ example shows how to read actual current driven into motor and convert it to amperes.
//read raw value of current smint32 readout; smRead1Parameter( handle, nodeAddress, SMP_ACTUAL_TORQUE, &readout ); //as raw value is integer in "hardware units" scale, convert it to amperes float actualcurrent; const float HWcurrentScale=560;//counts/A, this conversion value is for Argon actualcurrent=float(smint16(ana2))/HWcurrentScale; //current in amps is now in actualcurrent //TODO, do error checking for all sm commands
