Minimum/maximum winding diameter (Pr.1235, Pr.1236)
• Winding diameter calculation values are limited at the maximum diameter set in Pr.1235 Maximum winding diameter 1, or
the minimum diameter set in Pr.1236 Minimum winding diameter 1.
• The winding diameter after the averaging process (Pr.1249) is limited at the minimum/maximum diameter.

Minimum/maximum winding diameter selection (Pr.1237 to Pr.1242, X107
signal, X108 signal)
• Turn ON/OFF the Minimum/maximum winding diameter selection (X107 and X108) signals to select the maximum and
minimum winding diameters set in Pr.1237 to Pr.1242.
• For the X107 and X108 signals, assign the function by setting "107 (X107)" or "108 (X108)" in any of Pr.178 to Pr.189
(input terminal function selection).
