VGC During automatic operation, the function for selecting the velocity loop
gain, position gain switching speed, and PI/IP control for the X– and
Y–axes is:
0 : Disabled.
1 : Enabled.
When this parameter is set to 1, parameters N3S (bit 2 of No. 16050), KLV
(bit 7 of No. 16050), PIN and PIP (bits 3 and 2 of No. 16054), and Nos.
16828 to 16843 are also used.

[Data type] Bit axis
Use this parameter to select PI or IP control separately for ordinary
machining mode and nibbling mode during automatic machining. Only
the settings for the X– and Y–axes are valid.
PIP Velocity control in ordinary machining mode is:
0 : IP control.
1 : PI control.
PIN Velocity control in nibbling mode is:
0 : IP control.
1 : PI control.
16800 Nibbling pitch for level 1 (metric input)
16801 Nibbling pitch for level 2 (metric input)
16802 Nibbling pitch for level 1 (inch input)
16803 Nibbling pitch for level 2 (inch input)
[Data type] Two–word
Increment system IS–A IS–B Unit
Metric input 0.01 0.001 mm
Inch input 0.001 0.0001 inch
[Valid data range] 0 to 99999999
When using three–level switching for constant positioning time control
for the X– and Y–axes during nibbling, use these parameters to set the
nibbling pitches (common to the X– and Y–axes).
The value set for level 1 must be smaller than that set for level 2.
If level 3 is not used, set 99999999 for level 2.
