Very high-order control filters can be used with the
SimplIQ
drive.
The parameters of all filters are programmed into the vector KV[N], as follows:
Filter Parameters
Maximum
Order
Speed controller high-order filter
KV[0]…KV[21]
Position controller high-order filter
KV[22]…KV[43]
Analog position sensor filter
KV[44]…KV[55]
Order 4 (2 blocks)
Analog reference to speed controller
KV[56]…KV[67]
Order 4 (2 blocks
Table 7-1: KV[N] Filter Parameters
The high-order filter parameters of the speed controller are as follows:
Parameter Description
Value
Range
KV[0]
Is filter active?
0: Filter not active and bypassed. All
other filter parameters ignored.
100: Filter is active.
KV[1]
Last index in KV[N] used
for this filter
1+5n, where 1 ≤ n ≤ 9 is the number of
used second-order links. The
maximum resulting filter order is 18.
KV[2]…KV[6]
Parameters of first link
KV[7]…KV[11]
Parameters of second link
KV[12]…KV[16]
Parameters of third link
KV[17]…KV[21]
Parameters of fourth link
Table 7-2: Speed Controller High-order Filter Parameters
The high-order filter parameters of the position controller are as follows:
Parameter Description
Value
Range
KV[22]
Is filter active?
0: Filter not active and bypassed.
All other filter parameters ignored.
100: Filter is active.
KV[23]
Last index in KV[N] used
for this filter
23+5n, where 1 ≤ n ≤ 5 is the number of
used second-order links. The
maximum resulting filter order is 10.
KV[24]…KV[28]
Parameters of first link
KV[29]…KV[33]
Parameters of second link
KV[34]…KV[37]
Parameters of third link
KV[38]…KV[43]
Parameters of fourth link
