Example:
A filter consists of one second-order block and one first-order block. The second-order
block is a notch filter with a 300-Hz notch frequency and a damping of 0.14. The sample
time is 360 microseconds. The discrete equivalent of the filter is parameterized by:
k1 = 0.3372, k2 = 0.4573, k3 = -0.7277 and k4 = 0.5222.
The second block is a simple pole with a 400-Hz frequency. It may be represented by:
k1 = 0.1341, k2 = 0, k3 = 0 and k4 = 0.
The KV parameter vector should be programmed as follows:
Parameter Value Description
KV[0] 100
KV[1] 12 Last index used
KV[2] 16 First block, non-scheduled
KV[3] IQ25(0.3372) Parameter 1 (k1)
KV[4] IQ25 (0.4573) Parameter 2 (k2)
KV[5] IQ25 (-0.7277) Parameter 3 (k3)
KV[6] IQ25 (0.5222) Parameter 4 (k4)
KV[7] 16 Second block, non-scheduled
KV[8] IQ25 (0.1341) Parameter 1 (k1)
KV[9] 0 Parameter 2 (k2)
KV[10] 0 Parameter 3 (k3)
KV[11] 0 Parameter 4 (k4)
The value of KV[N] parameters for N = 12…47 is not important.
Above, IQ25(x) simply means
25
(2 )round x .
Be aware that the KV[N] manual programming is not required because the Composer
program performs it manually.
