PI/P control mode selection (Section A)
Automatic gain 1& 2 switch (Section B)
The selection of PI/P control mode switch and Automatic gain 1& 2 switch by parameters or from
input terminals can be used in following conditions.
(1) In speed control, to restrain acceleration/deceleration overshooting.
(2) In position control, to restrain oscillations and decrease the adjusting time.
(3) To decrease the possible noise caused by using Servo Lock function.
(A) Switching between PI/P Control modes
Switch over from PI to P mode is determined by setting of parameter Cn015.0 and according to
the selection options below:
Parameter
Signal
Name Setting Description
Control
mode
0
Switch from PI to P if the torque command is
greater than Cn016
1
Switch from PI to P if the speed command is
greater than Cn017
2
Switch from PI to P if the acceleration command is
greater than Cn018
3
Switch from PI to P if the position error is greater
than Cn019
