Output 1 as a 0-10V signal.
Parameter Settings
Parameter Value Description
[Trim In Select] 11, Preset 1 Preset 1 becomes the trim speed
[Scale1 In Hi] 10.0 V Hi value of Analog In 2
[Scale1 In Lo] 0 V Lo value of Analog In 2
[Scale1 Out Lo] 0 RPM Lo value of desired Trim
[Scale2 In Hi] 1800 RPM Hi value of Commanded Speed (Max Speed)
[Scale2 In Lo] 0 RPM Lo value of Commanded Speed
[Scale2 Out Hi] 180 RPM 10% of Max Speed
[Scale2 Out Lo] 0 RPM Corresponds to lo value of Commanded Speed
Destination Parameter Source Parameter Description
[Scale1 In Value] [Analog In2 Value] We are scaling Analog In 2 for our trim
[Scale2 In Value] [Commanded Speed] Use Commanded Speed as Input to Scale Block 2
[Scale1 Out Hi] [Scale2 Out Value] Use the output of Scale Block 2 to set the upper
limit of Scale Block 1 output
[Preset Speed 1] [Scale 1 Out Value] Use the scaled analog input as the trim reference
into Preset Speed 1
