Table 31 Fault Diagnosis and Corrective Actions (Cont’d)
Fault Display Description Details Corrective Action Rank*
Option reference selection
fault (OPE05)
• C-option is not connected although run
command from C-option is selected.
• C-option is not connected although fre−
quency reference from C-option is se−
lected.
• Check and set the constant data.
• Connect the C-option.
D
Control method selection fault
(OPE06)
PG contorl card is not connected during
flux vector control.
Connect PG control card. D
Multi-function analog input
selection fault (OPE07)
C-option is AI-14B and option/inverter
change is selected.
Check and set the constant data. D
Multi-function input/output
selection fault (OPE08)
Any of the following setting faults has oc-
curred:
• The setting unused in the control method
is selected for F4-01 and F4-04.
• The setting unused in the control method
is selected for F5-01 and F5-02.
• The setting unused in the control method
is selected for H1-01 to H1-06.
• The setting unused in the control method
is selected for H2-01 to H2-03.
• The setting unused in the control method
is selected for H3-05 and H3-09.
• The setting unused in the control method
is selected for H4-01 and H4-04.
• The setting unused in the control method
is selected for o1-01.
Check and set the constant data. D
R/min setting fault (OPE10)
The settings of E1-06 to E1-08 d o not satis-
fy the following conditions:
E1-06 ≧ E1-07 ≧ E1-08
Check and set the constant data. D
Energy-saving control
constants setting fault
Energy-saving control constant values are
out of range.
Check the motor nameplate values and in-
verter constants (E-constants) settings.
D
Digital operator fault (OPr)
The digital operator was disconnected dur-
ing operation by run command from the
digital operator.
• Check the wiring cable and the digital
operator connection.
• Replace the control card.
A
*1: The ranks are classified as follows:
A : Major fault (Motor coasts to a stop, digital operator indicator lights, and fault contact
is output.)
B : According to the constants for major/minor fault selection (constants underlined in the
table), major fault (Motorcoaststo a stop or decelerates to a stop, digital operatorindica
tor lights, and fault contact is output.) or minor fault (Rank C) can be selected.
C : Minor fault [Operation continues, digital operator indicator blinks, no fault contact is
output, and minor fault contact is output (when multi-function output is selected)].
D : Warning (Operation cannot be performed, digital operator indicator lights, no fault
contact is output, no minor fault contact is output.)
*2:
is displayed for the fault trace (U2 constant) and fault record (U3 constant).
*3: A load of 30% or less may result in incorrect detection of the load.
*4: The display is applicable for software No. 1033 or later (FLASH side). To check which ver-
sion is being used, refer to U1-14.
*5: If replacing the motor, contact your YASKAWA representative.
