desired). It is OK to allow some following error in the system. However, if
using multiple axes for simultaneous contoured moves, it is desirable that
each axis will have the same following error.
10. Increase the VGain servo loop parameter to minimize the position error during
the constant veloicty portion of the move. Typically, VGain will be set less than
500.
11. Turn the Position Error and Integral Error Traps on by returning to the
AerDebug utility and using the ParmSet command as follows:
ParmSet A FaultMask ####
“####” represents the number returned by the ParmGet command in step 2 of this
tuning procedure.
This will re-enable these fault conditions.
