The sensor filter parameters are:
Parameter Description Value Range
KV[44] Is filter active? 0: Filter not active and bypassed. All
other filter parameters are ignored.
100: Filter is active.
KV[45] Last index in KV[N] used
for this filter 45+5n, where 1 ≤ n ≤ 2 is the number of
used second-order links. The
maximum resulting filter order is 4.
KV[46]…KV[50] Parameters of first link
KV[51]…KV[55] Parameters of second link

The parameters of the analog speed reference filter are:
Parameter Description Value Range
KV[56] Is filter active? 0: Filter not active and bypassed. All
other filter parameters are ignored.
100: Filter is active.
KV[57] Last index in KV[N] used
for this filter 57+5n, where 1 ≤ n ≤ 2 is the number of
used second-order links. The
maximum resulting filter order is 4.
KV[58]…KV[62] Parameters of first link
KV[63]…KV[67] Parameters of second link

7.1. Internal Structure of a Filter Link
There are two types of filter links:
Type 16, a fixed link for which the next four link parameters are the filter coefficients.
A filter link has five parameters:

are stored inside the SimplIQ drive as integers. As a
result, when you read back these coefficients, they may have slightly different
values than those that you programmed.
