My Function
The
My Function
feature is configured using the settings of
F900
to
F977
and
is used to enhance the programmability of the
Q9 Plus ASD
by performing two
programmable functions: 1) the Combined Terminal Function, and 2) Logic
Operations.
Combined Terminal Function
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 ST and F to one terminal). Using
Virtual Terminals 1
–
4
(
F973
–
F976
) is required to use this function.
In the example below, the
ST
terminal assignment and the
F
terminal
assignment will be combined as one terminal 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.
Assign the
ST
function to the
S1
terminal (
F115
).
3.
Assign the
F
function to
Virtual Input Terminal 1
(
F973
).
4.
Set
Input Function Target 1
to
5
(
F900
). This setting assigns
S1
as the
control input terminal.
5.
Set
Output Function Assigned
to
21
(
F905
). This setting is a command
that writes the
F115
selection (S1) to
Virtual Input Terminal 1
, activating
both.
6.
Enable the
My Function
parameter at
F977
by selecting
My Function
Always On
or selecting
My Function With TB Signal
.
If set to
My Function Always On
, the combination of
ST
and
F
are
always On (both are connected to CC only during the S1
activation).
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
disconnection at either terminal will terminate the
My Function
programming (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 frequency.

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.
