If noise is bothersome during high speed rotation, it may be reduced by lowering the speed loop gain at high
speed.
Set this value to ensure the adequate response by suppressing noise and vibration at low speeds and in-
creasing the speed loop gain at high speeds for a high-speed spindle of machining center, etc.
As shown below, set the speed loop gain rate for the overspeed detection speed in SP073 (VGVN), and use
with SP074 (VGVS).
When not using, set to "0".
The overspeed detection speed (VLMT) is 115% of the maximum motor speed (TSP).
This function can be used when either Speed loop gain set 1 or Speed loop gain set 2 is selected.
---Setting range---
0 to 999 (%)
