DIV (divider)
Significance of other outputs:
• YIN: Integer quotient
• MOD = (Y - YIN) × X0 (remainder of the division)
• QF: The inverter sets QF = 1 when output value Y exceeds the permissible value range
or for division by zero.

INT (integrator)
The inverter limits output Y to values LU and LO. Also see limiter LIM.
As long as S = 1, then the inverter sets Y = SV.

Y = X0 / X1
The function block divides the inputs and limits the
result in the range -3.4E38 ... 3.4E38. With a divi-
sion of 0/0, Y remains unchanged.
