232 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;
5.00
(
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
).
0.00 …250.00
Proportional gain for speed controller.
