12.23 Combining and outputting two
output signals
Ｑ
• I want to combine the output terminal function to
make signals.
Ａ
• You can combine the operation of the output
terminal function to perform a logical operation for
output signals in the inverter to output various
signals.
• You can select three types of operators: AND, OR,
and XOR.
Selected signal
068: Logical output signal 1
(LOG1)
069: Logical output signal 2
(LOG2)
070: Logical output signal 3
(LOG3)
071: Logical output signal 4
(LOG4)
072: Logical output signal 5
(LOG5)
073: Logical output signal 6
(LOG6)
074: Logical output signal 7
(LOG7)
Example 1) Use a signal for which an AND operation
has been performed with a frequency equal to or
above the set frequency (003: FA2) and a low current
signal (033: LOC), and, when a current lowers after
the frequency has been determined, output the signal
as Logical output 1 (LOG1) to Output terminal
function 1.
• Output terminal function 1 [CC-01]: 062 (LOG1)
• Logical output signal 1 selection 1 [CC-40]: 003
(FA2)
• Logical output signal 1 selection 2 [CC-41]: 033
(LOC)
• Logical output signal 1 operator [CC-42]: 00
(AND)
Example 2) Use a signal for which an OR operation
has been performed with an overload advance notice
signal (035: OL) and a thermal warning signal (026:
THM), and, when a current falls outside the range,
output the signal as Logical output 3 (LOG3) to
Output terminal function 2.
• Output terminal function 2 [CC-02]: 063 (LOG3)
• Logical output signal 3 selection 1 [CC-43]: 035
(OL)
• Logical output signal 3 selection 2 [CC-44]: 026
(THM)
• Logical output signal 3 operator [CC-45]: 01
(OR)

About the inverter function
！
• All output signals are subject to operation. However,
you are not able to include the results of logical
operations [LOG1] to [LOG7] into the targets of
arithmetic operation.
