25.02 Speed proportional
gain
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;
5.00
(95.21 b1/b2)
If gain is set to 1.00, a 10% error (reference - actual value) in
the motor synchronous speed produces a proportional term of
10%.
Note: This parameter is automatically set by the speed
controller autotune function. See section Speed controller
autotune (page 38).
