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.
