Step 5 — Standard application
Force open/force close selection
The Force Open Selection would make the selected
function always off. Essentially this is a virtual switch that
is always open. The Force Close Selection would make the
selected function always on. Essentially this is a virtual
switch that is always closed. These options are assigned
to a function if we want to force a state without using a
hardware input.
The standard options are DigIn: Force Open - indication that
the parameter function is always going to be open, that
being said depending on the logic of the function this could
mean the function is always not active or always active.
When the selection of a function is DigIN: Force Closed -
indication that the parameter function is always going to be
closed, that being said again depending on the location of
the function this could mean the function is always active
or not active. Examples of these options would be P3.2
Start Signal 1, when set to “Force Open” and the drive is
looking at I/O terminals for control, in this case the drive
would never start since this Function is always Open. If this
function is set to “Force closed” the drive would always be
in a start mode when in that control location.
Example:
If we set Run Enable to Force Closed the drive is always
enabled. If we set the same function to Force Open the
drive would never be Enabled. If a Digital input is to be used
to activate this Run Enable the function should be assigned
to a hardware input(See below for DIGIN Selections).
DIGIN selection
This allows Assignment of a hardware digital input to a
function, this is set in a format of DigIN:X where X is one of
the 8 Digital inputs on the Main control board.
Example:
If we set Run Enable to DigI N:6 the drive will be enabled
when digital input 6 (Terminal 8) is closed, and would not be
enabled when digital input 6 (Terminal 8) is open.
Option board digIN selection
This allows Assignment of a hardware digital input on an
option card to a function, this is set in a format of DigIN:
Y:IO1:X where Y is the slot the option card is inserted on
the Main control board and X is the Input on the Board and
IO1 is the type of option board used.
Example:
If we set Run Enable to DigIN:A:IO5:6 the drive will be
enabled when digital input 6 is closed on the IO5 option
card which is inserted in Slot A, and would not be enabled
when digital input 6 on the option card is open.
Timer channel selection
A Time Channel is a virtual path to link the digital
output of a timer function to a digital input function. To
utilize this feature a timer or interval would need to be
assigned to a time channel 1 through 3, and the input
function to be controlled would need to be assigned to the
same time channel.
Example:
If we set Run Enable to DigIN:TimeChannel1 the drive will
be enabled when the timer assigned to Time Channel 1 is
active or High, and would not be enabled when the Time
Channel is inactive or Low.
