Large torque
command
In the previous 1
st
gain, if the absolute value of torque command exceed
(level+delay) [0.1%], it will switch to 2
nd
gain.
In the previous 2
nd
gain, if the absolute value of torque command keeps
below (level-delay) [0.1%] in the delay time, it will return to 1
st
gain.

Large speed
command
In the previous 1
st
gain, if the absolute value of the speed command
exceed (level+delay) [r/min], it will switch to 2
nd
gain.
In the previous 2
nd
gain, if the absolute value of the speed command
keeps below (level-delay) [r/min] and such state in the delay time, it will
return to 1
st
gain.
5
Large
position
deviation
In the previous 1
st
gain, if the absolute value of the position deviation
exceed (level+delay) [pulse], it will switch to 2
nd
gain.
In the previous 2
nd
gain, if the absolute value of the position deviation
keeps below (level-delay) [pulse] and such state in the delay time, it will
return to 1
st
gain.
Note: The unit of level and lag [pulse] acts as encoder resolution unit
during position control and as linear encoder resolution unit during
