oPE03
Terminal
Multi-Function Input Setting Fault.
Set values
other than “F” and “FF” are duplicated.
1.
Check the settings for H01.01 to H01.07, verify
that the same input is not used twice.
oPE04
Terminal
Parameters do not match.
The VFD, control
board, or terminal board has been replaced, and
the parameter settings between the controller
board or terminal board do not match.
1.
Press ENTER to view the parameter.
2.
Change parameter(s) to appropriate settings.
3.
Set A01.05 = 5550.
oPE07
Analog Selection
Multi-Function Analog Input Setting Fault.
Set
values other than 00 and 0F are duplicated.
1.
Check setting for H03.02 and H03.10. Verify that
the same value is not used twice.
oPE08
Terminal
Selection Parameter error.
A parameter has
been changed that is not available in the present
control method.
1.
Undo the last parameter change (if known).
2.
Scroll through modified parameters for obvious
setting errors.
3.
Perform a user initialize (A01.05=1110).
CAUTION: All settings will be restored to the
factory defaults.
oPE10
V/f Ptrn Setting
V/f Parameter Setting Error.
1.
Check Parameters E01.04 to E01.11.
oPE23
Load Check
Load Check setting error.
1.
Check C05.04 < C05.07 < C05.09.
OT1
Overtorque
Det 1
Overtorque Detection Level 1 Fault.
Current is
higher than set value (L06.02) for more than set
time (L06.03).
1.
Check for proper programming of L06.02 and
L06.03.
OT2
Overtorque
Det 2
Overtorque Detection Level 2 Fault.
Defined
by L06.05. Alarm default defined by L06.04.
1.
Check for proper programming for L06.05 and
L06.06.
oV
DC Bus Overvolt
Overvoltage Fault.
The DC bus voltage
exceeded the overvoltage level. Detection level:
230V class—approx. 410V
460V class—approx. 820V
1.
Extend the deceleration time.
2.
Check for proper DBU operation.
3.
Check the resistor.
4.
Check the line voltage.
5.
If on a load brake hoist, check the gear box.
oV
(flashing
)
DC Bus Overvolt
Overvoltage Fault.
Overvoltage occurs during
stop. Main circuit DC voltage rises above the
detection level while the VFD output is off.
Detection level: 410V or more for 230V, 820V or
more for 460V.
1.
Check the line voltage.
PF
Input Pha Loss
Input Phase Loss Fault.
VFD input power
supply has open phase.
1.
Check the line voltage.
2.
Remove power.
3.
Re-tighten the input terminal screws.
4.
Check line fuses.
rr
DynBrk Transistr
Braking Transistor Fault.
Internal Braking
transistor failed.
1.
Verify that the external braking resistor is con-
nected to the proper terminals.
2.
Confirm that the proper resistor is installed.
3.
Check for a short circuit across the braking
resistor.
UL1
Upper Limit 1 Err
Upper Limit 1—SLOW DOWN Indicator.
Upper
Limit 1—SLOW DOWN switch status is changed.
1.
May not require corrective action.
2.
Check the position of the Limit Switch.
3.
Check the condition of the Limit Switch.
4.
Check the conditions of/for terminal H01.XX
(U01.10).
Fault
Fault or Indicator Name/Description
Corrective Action
