◆ Operator Programming Errors

oPE Codes, Causes, and Possible Solutions
■
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. If an oPE occurs, investigate the cause and

Undertorque Detection 1
UL3
Drive output current (or torque in OLV, CLV, AOLV/PM, CLV/PM) less than L6-02 for longer than L6-
03 time.
Undertorque Detection 2
UL4
Drive output current (or torque in OLV, CLV, AOLV/PM, CLV/PM) less than L6-05 for longer than L6-
06 time.
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.
Uv
• 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.

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.
Initialization required.
Run Command/Frequency Reference Source Selection Error
Control Method Selection Error
Correct the setting for the control method.
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs
H3-02, H3-06, or H3-10 and PID functions conflict.
Parameter Selection Error
A function has been set that cannot be used in the motor control method
selected.
PID Control Selection Fault
PID control function selection is incorrect. Requires that PID control is
enabled (b5-01 = 1 to 4).
V/f Data Setting Error
The following setting errors have occurred where:
• E1-04 is greater than or equal to E1-06, E1-06 is greater than or equal
to E1-07, E1-07 is greater than or equal to E1-09, or E1-09 is greater
than or equal to E1-11.
• E3-04 is greater than or equal to E3-06, E3-06 is greater than or equal
to E3-07, E3-07 is greater than or equal to E3-09, or E3-09 is greater
than or equal to E3-11.
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
