The i500 series inverters have default parameter settings to
allow for basic out of the box operation as follows:
The parameter settings that by default assign the digital
I/O above shown to DI1-DI5 are:
P400.001 (ENABLE) = 1 [TRUE]
P400.002 (RUN) = 11 [digital
input 1]
P400.004 (RESET FAULT) = 12
[digital input 2]
P400.013 (REVERSE ROTATION
DIRECTION) = 13 [digital input 3]
P400.018 (ACTIVATE PRESET (BIT
0)) = 14 [digital input 4]
P400.019 (ACTIVATE PRESET (BIT
1)) = 15 [digital input 5]
While this allows a great many applications to be run right
out of the box with minimal programming, users may experience confusion when
applying settings for their own application as double assignment of functions
to I/O is possible.
For example if a user left the default setting of P400.013 (REVERSE ROTATION DIRECTION) = 13 [digital input
3] and also set P400.009 (RUN REVERSE) also
= 13 [digital input 3] both functions would be triggered simultaneously
by asserting DI3. Reversing the
direction of RUN REVERSE would make the drive run in the forward direction.
Users must clear unwanted functions (set = 0 [not
connected]) when developing their own configurations. An easy way to ensure unwanted double
assignments of I/O is not programmed the user can check the I/O tab display in
the Diagnosis tab of Easy Starter. Here
all I/O are shown with a listing of assigned functions. If an I/O point has more than one assignment
a box with a “…” appears next to the assignment.
Clicking on the “…” button will display a list of all the
functions which have the I/O point in question assigned.
Checking these assignments prior to commissioning is good
practice when developing configuration files for the i500.
If an error is seen the user can quickly correct the
situation by visiting the Flexible I/O configuration screen, clicking on the
function they want to remove and setting that to [0] not connected.
