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

Speed
command
variable
In previous 1
st
gain, if the absolute value of speed command variable
exceed (level+delay) [10r/min/s], it will switch to 2
nd
gain
In the previous 2
nd
gain, if the absolute value of the speed
command variable keeps below (level-delay) [10r/min/s] in the
delay time, it will return to 1
st
gain.
5
Speed
command
In the previous 1
st
gain, if the absolute value of the speed command
exceed (level+delay) [r/min/s], 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/s] and in the delay time,
it will return to 1
st
gain.
Note:
The parameter is invalid for the position gain. The actual position gain is always 1st gain.

In the speed control, if set P2.27 to 3~5, it is necessary to set triggering condition of gain
switching. The unit will vary with the switching mode and setting.
