Operation
Description
ABS(A)>
ABS(B)+/-C
OUTPUT
| INPUT A |
| INPUT B |
INPUT C
The OUTPUT is
TRUE if the magnitude of INPUT A is greater than or equal
to the magnitude of INPUT B - INPUT C.
The OUTPUT is FALSE if the magnitude of INPUT A is less than the magnitude of INPUT B - INPUT C. Otherwise the
OUTPUT is unchanged. In this way the block acts as a magnitude comparator with a comparison level of INPUT B and a
hysteresis band equal to +/- INPUT C.
ABS(A)>
=ABS(B)
OUTPUT
| INPUT A |
| INPUT B |
The OUTPUT is TRUE if the magnitude of INPUT A is greater than or equal
to the magnitude of INPUT B, otherwise the OUTPUT is FALSE.
A(1+B) The OUTPUT is set to INPUT A + ( INPUT A * INPUT B / 100.00 ).
IF(C) HOLD A If INPUT C is zero, the OUTPUT is set to INPUT A, otherwise the OUTPUT is unchanged.
On powering up the drive, the output will be pre-loaded with the last saved value of input B.
BINARY DECODE The OUTPUT is set according to which of the INPUTs are non-zero.

In the above table, 0 indicates that the corresponding input is not zero.
