Parameter
Dancer roller position detection signal adjustment
When terminal 4 input is voltage input, 0 V is minimum position and 5 V (10 V) is maximum position.
When current is input, 4 mA is minimum position and 20 mA is maximum position (initial value). When
0 to 7 V is output from the potentiometer, it is necessary to calibrate C7 (Pr. 905) at 7 V.

Example Control at a dancer center position using a 0 to 7 V potentiometer
After changing the current/voltage input switch to "V", set "2" in Pr. 267 to change terminal 4 input
to voltage input.
Input 0 V to across terminal 4 and 5 to calibrate C6 (Pr. 904). (% display displayed at analog
calibration is irrelevant to % of the feed back value.)
By inputting 7 V to across terminal 4 to 5, calibrate C7 (Pr. 905). (% display displayed at analog
calibration is irrelevant to % of the feed back value.)
Set 50% in Pr. 133.
NOTE
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different
setting may cause a fault, failure or malfunction. (Refer to page 6-178 for setting.)
