KI
FUNCTION: Integrator
DESCRIPTION:
The KI command sets the integral gain of the control loop. It fits in the control equation as
follows:
D(z) = KP + KD(z-1)/z + KI z/2(z-1)
The integrator term will reduce the position error at rest to zero.
ARGUMENTS: KI n,n,n,n,n,n,n,n or
KIA=n where
n is an unsigned numbers in the range 0 to 255 with a resolution of 0.001.
n = ? Returns the value for the specified axis.
