Operator Programming Errors - YASKAWA Varispeed L7 Instruction Manual

Operator Programming Errors

An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual param-
eter setting is inappropriate. The Inverter will not operate until the parameter is set correctly; however, no
alarm or fault outputs will occur. If an OPE occurs, change the appropriate parameter by checking the cause
shown in Table 7.3. When OPE error is displayed, press the ENTER key to display U1-34 (OPE Detected).
This monitor will display the parameter that is causing the OPE error.

The control board was replaced
and the kVA parameter (o2-04) is
set incorrectly
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:
• Duplicate functions were
selected.
• UP/DOWN Command(10 and

neously.
• The up/down commands (10
and 11) and Accel/Decel Ramp
Hold (A) were selected at the
same time.
• More than one of the Speed
Search inputs (61, 62, 64) were
set simultaneously.
• External Baseblock NO (8) and
External Baseblock NC (9)
were selected at the same time.
• The up/down commands (10
and 11) were selected while
PID Control was enabled.
• The Emergency Stop Com-
mand NO (15) and NC(17) are
set simultaneously.
• PID is enabled and UP and/or
DOWN (10 / 11) command are
set.
• HSB (68) and KEB (65/66)
command are set simulta-

Corrective Actions
Enter the correct kVA setting
(o2-04) by referring to the
table „Factory settings that
change with the Inverter kVA
setting" on page 5-60.
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.
