Logical Multiply/Divide Function Block
The logical multiply/divide function can be performed as either
standard math or per unit math. Per unit math lets you multiply/divide
internal drive units on a per unit basis, where 4096 is equal to one
unit. With per unit math, 4096 x 4096 = 4096, because you actually
multiply 1 unit by 1 unit to get 1 unit. The equation used for per unit
math is as follows:
