SV006 VGN2

Set the speed loop gain at the motor limitation speed VLMT (maximum rotation speed x 1.15) with
"VCS(SV029: Speed at the change of speed loop gain)".
Use this to suppress noise at high speed rotation during rapid traverse, etc. Then, the speed loop gain de-
creases at faster speed than the setting value of VCS. When not using, set to "0".

#2207

SV007 VIL

Set this when the limit cycle occurs in the full-closed loop, or overshooting occurs in positioning. The speed
loop delay compensation method can be selected with SV027/bit1,0.
Normally, use "Changeover type 2". Changeover type 2 controls the occurrence of overshooting by lowering
the speed loop lead compensation after the position droop gets 0.
When setting this parameter, make sure to set the torque offset (SV032).
---Setting range---
0 to 32767
#2208

SV008 VIA

Set the gain of the speed loop integral control.
Standard setting: 1364
Standard setting in the SHG control: 1900
Adjust the value by increasing/decreasing this by about 100 at a time.
Raise this value to improve contour tracking accuracy in high-speed cutting.
Lower this value when the position droop does not stabilize (when the vibration of 10 to 20Hz occurs).
---Setting range---
1 to 9999
