writing power

mgoiogana Posts: 2 Rating: (0)	I have a 840D and I would like to output a system variable (i.e. Z axis power (&AA_POWER[Z])) in a document that I will be able to work with in my computer. Is there any variable or command that creates this kind of document? The WRITE command is able to do this? If this is not possible, is there any other option to know the absorbed power apart from an analog output ( $AA_OUTA[1]=&AA_POWER[C1] )? Thanks,

mgoiogana Posts: 2 Rating: (0)	Thanks you for you reply, but I've not very clear how to program yet. with the comands $MA_DRIVE_SIGNAL_TRACKING and $AA_POWER would be enough to create the wanted removable document? All of this is new for me, so I can be asking stupid questions... Many thanks again,

Usually it's useful to useSYNACT therefore. e.g: .. ID=1 $R[0]=$AA_POWER[X1] ; writing every IPO-cycle the "X1-axis power" into R0 ... replacing the "$R[0]" by another variable is possible as well - just make sure the variablecan be used in coordination with SYNACT (see documentation)
