1155 [Line Spd Thresh]

Line speed detecting threshold. When the value of Par 1286 [Ref Line Speed] is
lower than the value of [Line Spd Thresh], the diameter calculation stops and the
diameter is kept at a constant value. When the value of [Ref Line Speed] overcomes
the threshold, the diameter calculation is enabled with an initial filter
corresponding to the value in Par 1206 [Diam Init Filter] for the time set in Par 1207
[Diam Stdy Delay]. At the end of this time the filter will be set to the value of Par
1162 [Diameter Filter].

1156 [Line Spd Gain]

Calibration value used to obtain Par 1160 [Line Speed Pct] = 100% at its maximum
value. The value of this parameter depends on the value of Par 1284 [Ref Spd
Source]:
[Line Spd Gain] = [32768 x 16384 / (maximum value of [Ref Spd Source] x 8)] -1
