6 PARAMETERS FOR POSITIONING CONTROL
6.3.2 Position control gain 1, 2
(1) Position control gain 1
(a) This gain is set in order to make the stabilization time shorter.
(b) If this gain is too high, it could cause overshoot and the value must therefore
be adjusted so that it will not cause overshoot or undershoot.

Time
Undershoot
(2) Position control gain 2
(a) This gain is set in order to increase position response with respect to load
disturbance.
(b) This gain is calculated and set with the load inertia ratio and the speed
control gain 2.
Speed control gain 2

Position control gain 2 =
1 + Load inertia ratio

POINTS
(1) If the position control gain 1 is too low, the number of droop pulses will increase
and a servo error (excessive error) will occur at high-speed operation.
(2) The position control gain 1 setting can be checked using a peripheral device.
(Refer to the help for each software for the checking method of the position
control gain 1 using a peripheral device.)
