value
100 PB30 Position loop gain after gain switching
Used to set the position loop gain when gain switching is
enabled.
When a value smaller than 1.0 rad/s is set, the value will
be the same as the setting value of [Pr. PB08].
This parameter is enabled only when "Manual mode
(_ _ _ 3)" is selected in "Gain adjustment mode selection"
of [Pr. PA08].
100 PB31 Speed loop gain after gain switching
Used to set the speed loop gain when gain switching is
enabled.
When a value smaller than 20 rad/s is set, the value will
be the same as the setting value of [Pr. PB09].
This parameter is enabled only when "Manual mode
(_ _ _ 3)" is selected in "Gain adjustment mode selection"
of [Pr. PA08].
100 PB32 Speed integral compensation after gain switching
Used to set the speed integral compensation when gain
switching is enabled.
When a value smaller than 0.1 ms set, the value will be
the same as the setting value of [Pr. PB10].
This parameter is enabled only when "Manual mode
(_ _ _ 3)" is selected in "Gain adjustment mode selection"
of [Pr. PA08].
