SE
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).
TdE Time Data Error
TrPC
IGBT Maintenance Time (90%)
IGBTs have reached 90% of their expected performance life.
UL3
Undertorque Detection 1
The current has fallen below the minimum value set for Torque Detection Level 1 (L6-02) for longer than the allowable time
(L6-03).
UL4
Undertorque Detection 2
The current has fallen below the minimum value set for Torque Detection Level 2 (L6-05) for longer than the allowable time
(L6-06).
UL6
Underload Det 6
Motor Underload
The load has fallen below the underload curve defined in L6-14.
Uv
Control Circuit Undervoltage
One of the following conditions occurred:
• 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.
u 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.

Error Name
oPE01
Drive Capacity Setting Fault
Drive capacity and the value set to o2-04 do not match.
oPE02
Parameter Range Setting Error
Use U1-18 to find parameters set outside the range.
oPE03
Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01 to H1-07.
oPE04 Initialization Required, Term <–> Ctrl Chg
oPE05 Run Command/Frequency Reference Source Selection Error
oPE07
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02 or H3-06 and PID functions conflict.
oPE08
Parameter Selection Error
A function has been set that cannot be used in the motor control method selected.
oPE09
PID Control Selection Fault
PID control function selection is incorrect. Requires that PID control is enabled (b5-01 = 1).
oPE10
V/f Data Setting Error
One of the following setting errors has occurred:
E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
oPE11
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
oPE33
Net Incompatible
Parameter selection is incompatible with the selected network P9-99
