Speed control gain1
If auto tuning 1 or 2 (parameter 8) or interpolation mode is selected, then this parameter will optimise itself
automatically. If auto tuning or interpolation mode is de-selected, then this parameter should not be changed.
Higher setting increases the response level but is liable to generate vibrations.
15
Position control gain 2
Set this parameter to increase position response to load disturbance. Higher setting increases the response level but
is liable to generate vibrations.
If auto tuning 1 or 2, manual setting method or interpolation mode (pr. 8) is selected, then this parameter will
optimise itself automatically. If auto tuning 1 or 2, manual setting method or interpolation mode is de-selected, then
the position control loop must be set via this parameter.
16
Speed control gain 2
Set this parameter to increase position response to load disturbance. Higher setting increases the response level but
is liable to generate vibrations.
If auto tuning 1 or 2 or interpolation mode (pr. 8) is selected, then this parameter will optimise itself automatically. If
auto tuning 1 or 2 or interpolation mode is de-selected, then the revolution speed control loop must be set via this
parameter.
17
Speed integral compensation
If auto tuning 1 or 2 or interpolation mode (pr. 8) is selected, then this parameter will optimise itself automatically.
