Combined Input Terminal Function (Cont.)
6. Enable the My Function parameter at
Always On or selecting My Function With TB Signal.
If set to My Function Always On, the combination of Accel/Decel
Switching 1 and Accel/Decel Switching 2 are always On (both are
activated during the I1 activation).
If set to My Function With TB Signal, set a discrete input terminal to My
Function Run Signal and activate it to enable My Function. Activate I1
to activate the Accel/Decel Switching 1 and Accel/Decel Switching 2
functions. A disconnection at either terminal will terminate the My
Function programming (discrete input terminal My Function Run Signal
is Anded with discrete input terminal I1).
Activate I1 and the Accel/Decel Switching 1
functions will be carried out using only I1.
With the aforementioned setup completed, provide a Frequency Command
(F004) and the motor will run at the commanded frequency.
Combined Output Terminal Function
Output terminals may also be combined to produce one output response to
multiple conditions using the computational operators of
Assigning more than one function to a discrete output terminal provides two
advantages: it effectively expands the number of input terminals, and 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
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 may listed in
combined in this manner.
Setup (Output Terminal Example)
1. Disable the My Function parameter at
starting upon completion of the setup.
From Program  Direct Access  Unknown Numbers, select Enabled.
2.
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 10 on pg. 242
settings.
5. Set Input Function Target 2 (F902) to 1026 (Low-Current Alarm). See
Table 10 on pg. 242 for a complete listing of available settings.
6. Set Input Function Command 1 (F901) to AND (3). This setting 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 transfer
the results of the logical AND to My Function Output 1 (OUT1).
8. Enable the My Function parameter at
Always On.
With the aforementioned setup completed in the example, once the Low Speed
Signal AND the Low-Current Alarm are active, the OUT1 terminal is
activated for the duration of the Low-Speed/Low-Current condition.

DANGER
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 confirmed 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.
