Operation
8) Setting the Position Error Limits
Look at the position error waveform on the oscilloscope. Note the maximum time that
position errors exist (from the time axis of the scope) and the maximum peak errors
being seen (from the value at the top of the screen). Use this values to set the position
error limits to provide suitable position error protection for the application.
Open the ‘Limits’ folder and ‘Position Limits’ sub-folder within the MotionView node tree
and set suitable values for the ‘Position Error’ and ‘Max Error Time’ parameters.
Maximum error and time period for error
existing.
In this particular example maximum error in pulses is 95.0. The time this peak error
occurs can be read from the oscilloscope at approximately ½ of a division with each
division equal to 100ms, hence the error pulse lasts approximately 50mS. Suitable
settings for position error within this application might be as follows, although looser or
tighter limits could be applied depending on the requirements of the application.
Description Value
Position Error 100
Max Error Time 50
9) End Tuning
Remove the Enable Input from input A3 (disable the drive).
