‹ Operator Programming Errors An Operator Programming Error (OPE) occurs when two or more parameter related to each other are set inappropriately or an individual parameter setting is incorrect. The Inverter does not operate until the parameter setting is corrected; however, no other alarm or fault output 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. EN-23 Display Alarm Fault Meaning Corrective Actions PUF DC Bus Fuse Open DC Bus Fuse Open The fuse in the main circuit is blown.
Warning: PG (encoder) pulses have not been received for a time longer than the setting in F1-14. • Check the motor and the motor cables for short circuits or insulation failures (phase- to-phase). • Replace the inverter after correcting the fault. RR DynBrk Transistr Dynamic Braking Transistor The built-in dynamic braking transistor failed • Cycle power to the inverter. • Replace the inverter. UV1 DC Bus Undervolt (only in stop condi- tio) The DC bus voltage is below the Undervoltage Detection Level (L2-05). The default settings are: 200V class: 190 VDC 400 V class: 380 VDC • 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 Main Circuit MC Operation Failure No MC response during Inverter operation. Replace the Inverter. UV2 CTL PS Undervolt Control Power Supply Undervoltage Undervoltage of the control circuit while the Inverter was running. • Remove all connection to the control termi- nals and cycle the power to the Inverter. • Replace the Inverter. Display Meaning Corrective Actions OPE01 kVA Selection Inverter kVA Setting Error Enter the correct kVA setting in o2-04. OPE02 Limit Parameter setting is out of its range Verify the parameter settings.
OPE03 Terminal 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 11) were not selected simultaneously. • 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 Command NO (15) and NC(17) are set simultaneously. • PID is enabled and UP and/or DOWN (10 / 11) com- mand are set.
• HSB (68) and KEB (65/66) command are set simulta- neously. Verify the parameter settings in H1- OPE05 Sequence Select RUN/Reference Command Selection Error The Reference Source Selection b1-01 and/or the RUN Source Selection parameter b1-02 are set to 3 (option board) but no option board is installed. • 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 OPE06 PG Opt Missing Control Method Selection Error One of the control methods needing a PG feedback was selected (A1-02 = 1 or 3), but a PG option board is not installed.
Verify the control method selection in parameter A1-02 and/or the installation of the PG option board.
