Speed Loop Proportional Gain vs. Response Characteristics
Motor
speed
Speed loop proportional gain is high.
(Machine vibration will result if gain is too high.)
Speed loop proportional gain is low.

Speed Loop Integral Gain vs. Response Characteristics
Motor
speed
Time
Speed loop integral gain is high.
(Integral time constant value is small.)
Speed loop integral gain is low.
(Integral time constant value is large.)

Position Loop Adjustment
·
Adjust the position loop after adjusting the speed loop.
·
Good response characteristics are obtained by increasing the position loop proportional gain provided
that the overshooting or undershooting of the Servo System does not result.

Overshooting
Position loop proportional gain is high.
Position loop proportional
gain is low.
Undershooting
·
Overshooting and undershooting can be easily checked by checking the output voltage of the NM ter-
minal with an oscilloscope.
