11. CONTROL FUNCTION
181
The following functions have been added to high–speed positioning
control for the table axes (X– and Y–axes):
1. Velocity loop gain switching according to the positioning distance
(seven levels)
2. Nibbling constant positioning time control (three levels)
3. Position gain switching speed and PI/IP control selection
During automatic operation, the velocity loop gains (PK1V and PK2V)
for the X– and Y–axes can be set to one of seven levels, according to the
positioning distance, specified with existing parameters (No. 16055 to
No. 16066). Upon a reset, the standard parameter settings (No. 2043 and
No. 2044) are selected.
Bit 5 (VGC) of parameter No. 16051 is set to 1 and bit 7 (KLV) of
parameter No. 16050 is set to 1.
Positioning distance : No. 16055 to No. 16066
Velocity loop gain (integral) PK1V : No. 16828 to No. 16834
Velocity loop gain (proportional) PK2V : No. 16835 to No. 16841
