Operator Programming Errors - Omron VARISPEED L7 Manual

Operator Programming Errors

An Operator Programming Error (OPE) occurs when two or more parameter related to each other are set inap-
propriate or an individual parameter setting is incorrect. The Inverter does not operate until the parameter set-
ting is set correctly; however, no other alarm or fault outputs will occur. If an OPE occurs, change the related
parameter by checking the cause shown in
to see U1-34 (OPE Detected). This monitor displays the parameter that is causing the OPE error.

Probable Causes
The control board was replaced and the
kVA parameter (o2-04) is incorrect.
A not suitable software has beenn
installed on the inverter.
Parameter setting was outside of the
allowable range.
One of the following errors has been
made in the multi-function input
(H1-01 to H1-05) settings:
• Functions were selected duplicative.
• External Baseblock NO (8) and
External Baseblock NC (9) were
selected at the same time.
• The Emergency Stop Command NO
(15) and NC(17) are set simulta-
neously.
Option board is not installed or is
installed incorrectly
One of the control methods needing a
PG feedback was selected (A1-02 =3/
6), but a PG option board is not
installed.
A setting has been made, which is not
applicable with the current control
method.
Example: A function used only with
open loop vector control was selected
for V/f control.
Corrective Actions
Enter the correct kVA setting by
referring to page 5-63, Factory Set-
tings Changing with Inverter
Capacity (o2-04)
Compare U1-14 and the software
number in the nameplate. Replace
the software if necessary.
Verify the parameter settings.
Verify the parameter settings in H1-
Verify that the board is installed.
Remove the power supply and re-
install the option board again
Recheck the setting of b1-01 and
b1-02.
Verify the control method selection
in parameter A1-02 and/or the
installation of the PG option board.
Verify the control method and the
function.
