605C Frequency Inverter
Functional Description
OUTPUT is generated from the inputs according to the operation type selected. The output is
always limited to be within the range -300.00% to +300.00%.
Operation
Description
IF(C) -A
If INPUT C is not zero the OUTPUT is minus INPUT A, otherwise the
OUTPUT is the same as INPUT A.
ABS(A+B+C)
The OUTPUT is set to the absolute value of INPUT A + INPUT B + INPUT
C.
SWITCH(A,B)
OUTPUT
INPUT A
INPUT B
INPUT C
If INPUT C is zero the
OUTPUT is set to INPUT A,
otherwise the output is set to
INPUT B
(A*B)/C
The OUTPUT is set to (INPUT A * INPUT B) / (INPUT C). The algorithm
compensates for the remainder term.
Parameter Descriptions
