(c)-2 Effect of gain adjustment
According to the description in 3-1), the final value of parameter No.
2048 must be determined to be 100. However, small protrusions are
still left at the reverse points. This is because the gain adjustment is
insufficient in this example. The power to suppress the position gain
and velocity loop gain protrusions is strong and stable. Therefore, it is
necessary to make gain adjustments thoroughly before the backlash
acceleration adjustment.
The figure shown below is the result of the gain adjustment, where
backlash acceleration is not used. Even when backlash acceleration is
not used, protrusions are almost eliminated. Therefore, the importance
of gain adjustment can be understood.
(Adjustment items)
• Application of high-speed HRV current control
• Velocity loop gain: 600% (200% in the above example)
• Position gain: 100/s (30/s in the above example)
