Can be set when Pr. 291 = "1, 11, 21, or 100".

Setting Pr. 785 = "2" sets the taper ratio setting as the terminal 4 input regardless the Pr. 733 setting.
REMARKS
• While the dancer/tension control selection X83 signal is ON, the setting values of Pr. 731 to Pr. 734 and Pr. 763 have higher precedence
over the other assigned terminal settings such as Pr. 868, Pr. 785 = "1", and Pr. 406. (Example: When Pr. 731 = "5" and Pr. 868 = "0", the
terminal 1 is set to the dancer signal input.)
• For the taper setting analog input, the setting of Pr. 785 Terminal 4 function setting has higher precedence.
• While tension control is valid (Pr. 800 = "6 or 16"), the following parameter settings are invalid: Pr. 731 Dancer signal input selection,
Pr. 732 Dancer main speed command input selection, and Pr. 734 Dancer tension setting input selection.
• The dedicated-function parameters take the following precedence over each other. When several functions are assigned to a terminal,
input to the function of lower precedence is regarded as 0.
Terminal 4 function setting (Pr. 785 = "2") > Pr. 731 Dancer signal input selection > Pr. 763 Line speed input selection > Pr. 732 Dancer main speed
command input selection > Pr. 733 Taper setting analog input selection > Pr. 734 Dancer tension setting input selection.
