Line speed input setting (Pr. 763 to Pr. 768)
(1)
Line speed input selection (Pr. 763)
Select input terminal of line speed command to perform winding diameter calculation.
When material thickness is set to Pr. 752 Material thickness d1 (Pr. 752
speed but from the addition of material thickness and rotation number of a roll, but not from line speed. (Refer to page 35).

To switch among 0 to 5VDC, 0 to 10VDC, and 0 to 20mA, use Pr. 73 setting as well as voltage/current input switch. (Refer to the Instruction Manual for
details.)
*3
To switch among 0 to 20mA, 0 to 10VDC, and 0 to 5VDC, use Pr. 267 setting as well as voltage/current input switch. (Refer to the Instruction Manual for
details.)

Unit conversion for line speed (Pr. 764, Pr. 765, Pr. 766, Pr. 767)
Convert pulse input unit (kpps) and analog input unit (%), which are selected in Pr.763 Line speed input selection, to line
speed unit (mm(m)/min(sec)).

Input filter (Pr. 768)
Set the time constant of the first-order lag filter. Set a large time constant when you want to delay the tracking of the
speed command, and when the analog input voltage fluctuates, etc.
Filters can be applied to pulse train input when Pr. 763 = "1, 2 or 7" by using Pr. 768 Line speed input filter time constant.
Filters can be applied to analog input with input filter time constant of Pr. 74 when Pr. 763 = "3, 4, 5 or 6".
