214 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.
Note:
This parameter is automatically set by the speed
controller autotune function. See section
(page
).
0.00…250.00
Proportional gain for speed controller.
