7 Troubleshooting

Operator Programing Errors
An Operator Programming Error (oPE) occurs when an inapplicable parameter is set or an individual parameter setting is
inappropriate. When an oPE error is displayed, press the ENTER button to display U1-18 (oPE fault constant). This
monitor will display the parameter that is causing the oPE error.
Digital Operator
Drive capacity and value set to o2-04 do not match.
oPE01
oPE02 Parameters were set outside the allowable setting range.
A contradictory setting is assigned to multi-function contact
inputs H1-01 through to H1-08.
• The same function is assigned to two inputs. (this excludes
"External fault" and "Not used")
oPE03
• Input functions which require the setting of other input
functions were set alone.
• Input functions that are not allowed to be used
simultaneously have been set.
• The run command source (b1-02) or frequency reference
source (b1-01) is set to 3 but no option card is installed.
oPE05
• The frequency reference source is set to pulse input but
H6-01 is not 0.
Settings to multi-function analog inputs H3-02 and H3-10
and PID functions conflict.
• H3-02 and H3-10 are set to the same value. (this excludes
oPE07
settings 0 and F)
• PID functions have been assigned to both analog inputs and
the pulse input at the same time.
A function has been set that cannot be used in the control
oPE08
mode selected.(might appear after control mode change)
The V/f pattern setting is incorrect.
oPE10
One of the following setting errors has occurred while Online
Tuning is enabled in OLV (A1-02 = 2):
• E2-02 has been set below 30% of the original default value
oPE18
• E2-06 has been set below 50% of the original default value
• E2-03 = 0

Auto-Tuning Errors
Digital Operator
Motor data fault
The input motor data are not valid. (e.g. the base frequency
Er-01
and base speed do not fit).
Minor Fault
Er-02 • The wiring is faulty.
• The load is too heavy.
The STOP button was pressed and Auto-Tuning was
Er-03
canceled.
Resistance fault
• Wrong input data.
Er-04
• Auto tuning exceeded the given time frame.
• Calculated values out of range.
No-Load Current Error
• Incorrect data was entered.
Er-05
• Auto tuning took too long.
• Calculated values out of range.
Rated Slip Error
• Wrong data input.
Er-08
• Auto tuning exceeded the given time frame.
• Calculated values out of range.

Corrective Action
Correct the value set to o2-04.
Set parameters to the proper values.
• Fix any incorrect settings.
• Refer to the Technical Manual for more details.
• Install the required option card.
• Correct the values set to b1-01 and b1-02.
• Fix any incorrect setting.
• Refer to the Technical Manual for more details.
• Fix any incorrect setting.
• Refer to the Technical Manual for more details.
• Check the V/f pattern settings.
• Refer to the Technical Manual for more details.
Make sure E2-02, E2-03, and E2-06 are set the correct values.
Corrective Action
Re-enter the data and repeat Auto-Tuning.
• Check the wiring.
• Check the load. Always perform Auto-Tuning with the load
uncoupled from the motor.
Repeat the Auto-Tuning.
• Check the input data.
• Check the wiring.
• Re-enter the data and repeat the Auto-Tuning.
