218 Parameters
Defines the proportional gain (K
p
) of the speed controller. Too
high a gain may cause speed oscillation. The figure below
shows the speed controller output after an error step when
the error remains constant.
10.00
If gain is set to 1, a 10% change in error value (reference -
actual value) causes the speed controller output to change by
10%, ie. the output value is input × gain.
0.00…250.00
Proportional gain for speed controller.
100 = 1
No.
