Combined Terminal Function
Output terminals may also be combined to produce one output response to
multiple conditions using the computational operators of
Table 16 on pg. 244
.
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 13 on pg. 239
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
Direct Access
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 13 on pg. 239
for a complete listing of available
settings.
5.
Set
Input Function Target 2
(
F902
) to
1026
(Low Current Alarm). See
Table 13 on pg. 239
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
F977
by selecting
My Function
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.
See the
My Function Instruction Manual
(P/N E6581335) for a complete
description of the setup requirements and operational information of the
My
Function
parameter.
Direct Access Number — F977
Parameter Type —
Selection List
Factory Default —
None
(Disabled)
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 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.
