LED Display ALM FLT
• Input voltage drop or phase imbalance.
Input Phase Loss
• One of the input phase is lost.
• Loose wires at the drive input.
Braking Transistor
Fault
The internal braking transistor is broken.
The voltage in the DC bus fell below the undervoltage detection level
DC Undervoltage
(L2-05).
• The power supply failed or one input phase has been lost.
• The power supply is too weak.
Controller
Undervoltage
The drives controller power supply voltage is too low.
DC Charge Circuit
Fault
The charge circuit for the DC bus is broken.

Operator Programming Errors
An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual parameter setting is inappropriate. When an
OPE error is displayed, press the ENTER button to display U1-18 (OPE fault constant). This monitor will display the parameter that is causing the
OPE error.

oPE01
Drive capacity and value set to o2-04 do not match.
oPE02
Parameters were set outside the allowable setting range.
A contradictory setting is assigned to multi-function contact inputs
H1-01 through to H1-06.
• The same function is assigned to two inputs. (this excludes
oPE03
"External fault" and "Not used")
• Input functions which require the setting of other input functions
were set alone.
• Input functions that are not allowed to be used simultaneously
have been set.
• The run command source (b1-02) or frequency reference source
oPE05
(b1-01) is set to 3 but no option board is installed.
• The frequency reference source is set to pulse input but H6-01 is
not 0.
Settings to multi-function analog inputs H3-02 and H3-10 and PID
functions conflict.
oPE07
• H3-02 and H3-10 are set to the same value. (this excludes settings
"0" and "F")
• PID functions have been assigned to both analog inputs and the
pulse input at the same time.
oPE08
A function has been set that cannot be used in the control mode
selected. (might appear after control mode change)
oPE10
The V/f pattern setting is incorrect.

Corrective Action

• Check the power supply.
• Make sure that all cables are properly fixed to the correct terminals.
• Cycle the power supply.
• Replace the drive if the fault reoccurs.
• Check the power supply.
• Make sure, that the power supply is strong enough.
• Cycle power to the drive. Check if the fault reoccurs.
• Replace the drive if the fault continues to occur.
• Cycle power to the drive. Check if the fault reoccurs.
• Replace the drive if the fault reoccurs.
