■ (Example 1) Logical conjunction (AND) operation example
 Set the "signal that turns on when the output current drops while the output frequency is above
the set value" to [LOG1] and output it from the output terminal [11].
■ (Example 2) Logical disjunction (OR) operation example
 Set the "signal that turns on when the output current is outside the range while either overload
or electronic thermal overload state is occurring" to [LOG2] and output it from the output
terminal [11].
■ (Example 3) Exclusive disjunction (XOR) operation example
 Set the "signal when the output current is within the specified range" to [LOG3] and output it
from the output terminal [12].
