5.3.3. Adjustment of Velocity Loop Integration Frequency (VI)
l
Perform the adjustment of velocity loop integration frequency (VI) after the adjustment of the
velocity loop proportional gain (VG).
1 ） Start the program for adjusting the parameter VI.
The screen displays the message as shown below and you can change the VI setting up and down
using the (+) and the (-) keys.
(Actually the VI parameter differs with a load inertia and rotation angel.)

: Press the key to store the VI setting.
(2) This part indicates the current setting of VI.
(3) This part indicates the changing resolution of VI data when the (+) or the (-) key is
pressed. (VI changing resolution)
(4) Response index number: Small number denotes better response to the command.
(5) Positioning index number: Smaller number requires less time to complete a
positioning.
！
Caution : Pressing the SP key will alter the changing resolution of VG for one
press of the (+) or the (-) key to 1/10 of the current setting.
Pressing the BS key will alter the changing resolution of VG for one
press of the (+) or the (-) key to 10 times of the current setting.
2) Press the (+) key several times observing motion of the Motor.
