SSI
SSI encoders normally use gray code data format. However, some encoders use binary format which may be selected by setting this parameter to
one.
0 = 0ms, 1 = 1ms, 2 = 2ms, 3 = 4ms, 4 = 8ms, 5 = 16ms
A sliding window filter may be applied to the feedback. This is particularly useful in applications where the feedback is used to give speed feedback
for the speed controller and where the load includes a high inertia, and so the speed controller gains are very high. Under these conditions, without a
filter on the feedback, it is possible for the speed loop output to change constantly from one current limit to the other and lock the integral term of the
speed controller.
