Operator Programming Errors
n oPE Codes
An Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to an
inappropriate value.
The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, does not
trigger an alarm or fault output. When an oPE appears on the operator display, press the ENTER button to view U1-18 and
see which parameter is causing the oPE.

YASKAWA TOEP YAIP1W 02E YASKAWA AC Drive - iQpump1000 Installation & Start-up Guide
Motor Switch during Run
A command to switch motors was entered during run.
MEMOBUS/Modbus Communication Test Mode Error
Note: This alarm will not trigger a multi-function output terminal that is set for alarm output
(H2-oo = 10).
Suction Pressure Loss
Wire-break detection for suction pressure.
Thermistor Disconnect
The thermistor used to detect motor temperature has become disconnected.
IGBT Maintenance Time (90%)
IGBTs have reached 90% of their expected performance life.
Undertorque Detection 1
The current has fallen below the minimum value set for torque detection (L6-02) for longer than the allowable time
(L6-03).
Undertorque Detection 2
The current has fallen below the minimum value set for torque detection (L6-05) for longer than the allowable time
(L6-06).
Motor Underload
The load has fallen below the underload curve defined in L6-14.
Undervoltage
One of the following conditions was true when the drive was stopped and a Run command was entered:
• DC bus voltage dropped below the level specified in L2-05.
• Contactor to suppress inrush current in the drive was opened.
• Low voltage in the control drive input power. This alarm outputs only if L2-01 is not 0 and DC bus voltage is
under L2-05.
Output Voltage Detection Error
Problem detected with the voltage on the output side of the drive.
Water Level Loss
Analog Water Level / Suction Pressure / Aux PI Feedback Lost
Network Water Level / Suction Pressure / Aux PI Feedback is now being used because a wire-break was detected
with the analog signal.
Water Level Analog Input Wire Break (WL Wire Break) is effective when Q4-16 is set to 1 (Alarm) or 2 (Fault).
Suction Pressure Analog Input Wire Break (SP Wire Break) is effective when Q5-19 is set to 1 (Alarm) or 2 (Fault).
Waiting for Run
Drive Capacity Setting Fault
Drive capacity and the value set to o2-04 do not match.
Parameter Range Setting Error
Use U1-18 to find parameters set outside the range.
Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01 to H1-08.
