watch - real time motion inspection

watch [motor=1] [nstep=1000] [span=10] [graph=1] [period=100] [mode=jog]

watch puts out a file watch.log which contains:

time(ms) command_position actual_position, difference, DAC_output

It then displays the results graphically.

mode= the default mode jog performs a jogged move mode program performs a programmed move.

graph= default plots adjust plot scale to command position, value of 2 adjusts plot scale to observed range.

period= changes the rate of sampling compared to the servo cycle of .24mS.

span= changes the observation time default value of 10 seconds.

motor= changes the motor from the default value of 1.

nstep= changes the motion step the default value of 1000. Setting to zero will not send any jog or program move command.
