Operator Programming Errors (OPE)
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 the table below. When an OPE error is displayed, press the ENTER
key to see U1-34 (OPE Detected). This monitor displays the parameter that is causing the OPE error.

Meaning
The fuse in the main circuit is blown.
Warning:
Never run the Inverter after replacing the DC bus
fuse without checking for shorted components.
The built-in dynamic braking transistor failed.
No output contactor response S1-16 or longer.
The output current at start was below 25% of no-load
current.
The output current during run was below 25% of no-
load current.
The motor position moved during Zero Servo Opera-
tion.
The DC bus voltage is below the under voltage
Detection Level
(L2-05). The default settings are:
200V class: 190 VDC
400 V class: 380 VDC
Main Circuit MC Operation Failure
No MC response during Inverter operation.
Control Power Supply Undervoltage
Undervoltage of the control circuit while the Inverter
was running.
Meaning
Corrective Actions
• Check the motor and the motor cables for short cir-
cuits or insulation failures (phase-to-phase).
• Replace the inverter after correcting the fault.
• Cycle power to the Inverter.
• Replace the Inverter.
Check the output contactor.
Check the output contactor.
Check the output contactor.
• Increase the torque limit.
• Decrease the load torque.
• Check for signal noise.
• Check the input voltage.
• Check the wiring of the input terminals.
• Check the input voltage and the wiring of the input
terminals.
• Extend the settings in
• C1-01/03/05/07
Replace the Inverter.
• Remove all connection to the control terminals and
cycle the power to the Inverter.
• Replace the Inverter.
Corrective Actions
Enter the correct kVA setting in o2-04.
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.
Check parameters (E1-
). A frequency/voltage value may
be set higher than the maximum frequency/voltage.
