• If the 1st digit “x” of Frequency Offset Selection (n146) is 1 or 2 (fre-
quency offsets enabled), the set values of constants n083 to n085 will
function as frequency offsets.
• In order to activate the offset frequencies 1 to 3 of the Multi-function
Input Selections (n050 to n056) must be programmed to 30, 31 or 33.
Depending on the input status following combinations of the offset
frequencies can be used. Note that the sign specified with “y” is used.
• The enabled offset amount can be monitored on the display of U-12
on the Digital Operator.
