1154 [Roll Diameter]
Displays the calculated roll diameter. Note: This parameter can be
assigned to an analog output as a percentage of Par 1153 [Max
Diameter].

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

1157 [Diameter Reset]
Diameter reset. When this parameter is set to “1”, the diameter
starting value is set to the value in Par 1168 [Diam Preset Sel].

1158 [Diam Threshold]
Diameter threshold as a percentage of Par 1153 [Max Diameter]. Par
1159 [Diameter Reached] is set to “1” when the value in this
parameter is exceeded.

1159 [Diameter Reached]
Indication that the diameter threshold set in Par 1158 [Diam
Threshold] has been exceeded.
• “0” = The diameter threshold has not been exceeded.
• “1” = The diameter threshold has been exceeded.

1161 [Diam Calc Dis]
Enables/Disables the diameter calculation (see also Par 1155 [Line

parameter is changed to 0 “Off” while the diameter is being
calculated.
