This parameter Enables/Disables the configured My Function fea-
ture of the Q9 Plus ASD.
Settings:
0 — None (Disabled)
1 — My Function with Terminal Board Signal (discrete terminal)
2 — My Function Always On
My Function
The My Function feature is configured using the settings of
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
required to use this function.
In the example below, the ST terminal assignment and the F ter-
minal assignment will be combined as one terminal to illustrate
this feature. However, any two of the discrete output terminal
assignments listed in
Table 12 on pg. 257
this manner.
Setup (Example)
1. Disable the My Function parameter at
system from starting upon completion of the setup.
2.Assign the ST function to the S1 terminal
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
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 activa-
tion).

This parameter must always be
set to None at the start of the My
F900
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.
