Combined Terminal Function (cont.)
If set to My Function With TB Signal, set a discrete input terminal
to My Function Run Signal and connect it to CC to enable My
Function. Connect S1 to CC to activate the ST+F function. A dis
-
connection at either terminal will terminate the My Function pro -
gramming (discrete input terminal My Function Run Signal is
Anded with discrete input terminal S1).
Connect S1 to CC and the F-to-CC + the ST-to-CC functions will
be carried out using only S1.
With the aforementioned setup completed, provide a Frequency
Command (
F004 ) and the motor will run at the commanded fre -
quency.
Output terminals may also be combined to produce one output
response to multiple conditions using the computational opera
-
tors of Table 15 on pg. 262 .
Assigning more than one function to a discrete output terminal
provides two advantages: it effectively expands the number of
input terminals, and it reduces the number of cables required to
support the input/output functions (e.g., assigning Low-Speed
Detection and Low Current Detection to one output terminal).
Using Virtual Terminals 1 – 4 (
F973 – F976 ) is required to use
this function.
In the example below, the Low-Speed Signal (detection) terminal
assignment and the Low Current Detection terminal assignment
will be combined as one terminal output to illustrate this feature.
However, any two of the discrete output terminal assignments
listed in
Table 12 on pg. 257 may be combined in this manner.
Setup (example)
1. Disable the My Function parameter at F977 to prevent the
system from starting upon completion of the setup.
2.From Program

Unknown Numbers, select
Enabled.
3.Set the OUT1 terminal ( F130 ) to My Function Output 1 (222).
4.Set Input Function Target 1 ( F900 ) to 1004 (Low-Speed Signal
detection). See Table 12 on pg. 257 for a complete listing of
available settings.
5.Set Input Function Target 2 ( F902 ) to 1026 (Low Current
Alarm). See Table 12 on pg. 257 for a complete listing of avail -
able settings.
6.Set Input Function Command 1 ( F901 ) to AND (3). This set -
ting assigns an operator to the Input Function Target 1 and the
Input Function Target 2 settings.
7.
Set Output Function Assigned (
F905
) to 1222. This setting will trans -
fer the results of the logical AND to My Function Output 1 (OUT1).

Changeable During Run —
No
This parameter must always be
set to
None at the start of the My
Function setup and remain set to
None until all of the My Function
parameter settings have been con -
firmed as being correct.
If enabled for normal operation
using settings
1 or 2 , the motor
may start and engage the driven
equipment unexpectedly upon
receiving a
Run signal during the
My Function setup.
