3.10.6 Analog output signal for dancer tension setting (Pr. 718, Pr. 719, Pr. 733, Pr. 734,
Pr. 785, Pr. 787 to Pr. 789)
Dancer is controlled with an air cylinder. Set an analog signal, which is output for tension setting to control the air cylinder,
with terminal FM/AM.
Set Pr. 785 Terminal 4 function setting and Pr. 733 Taper setting analog input selection to use the taper setting analog input signal
with an analog input terminal.
(1) Control diagram
(2) Connection example
When potentiometer is input
(3) Tension output command setting
To output tension commands from an inverter, set the AM and FM output terminals as follows.
Use
Pr. 900
to calibrate the terminal FM, and
Pr. 901
for the terminal AM.
