Description Causes and Solutions
Load is too heavy.
• Reduce the load.
Accel/decel ramp is too short.
• Lower the settings for the acceleration and deceleration in the A2
sub-menu.
The output voltage is too high.
• Adjust the preset V/f pattern by reducing Motor Mid Frequency A (A5) and
Motor Min Frequency (A5).
Note: Do not lower this parameter excessively, as this will
reduce load tolerances at low speeds.
Drive capacity is too small.
• Replace the drive with a larger model.
Overload occurred when operating at low speeds.
• Reduce the load when operating at low speeds.
• Replace the drive with a model that is one frame size larger.
• Lower the Carrier Frequency.
Excessive torque compensation.
• Reduce the Torq Comp Gain (A1) until there is no speed loss but less
current.
Output current fluctuation due to input phase loss.
• Check the power supply for phase loss.
Parameter settings are not appropriate for the load.
• Check the settings of parameters.
Fault on the machine side (e.g., machine is locked up).
• Check the status of the load. Remove the cause of the fault.
Parameter settings are not appropriate for the load.
• Check the settings of parameters.
The drive model selection (U6) and the actual capacity of the drive are not the
same.
• Correct the value set as Drive Model Selection (U6).
Parameters were set outside of the possible setting range.
• Power cycle the drive.
• Set parameters to the proper values.
Note: Use oPE Flt Parameter (F2) to find which parameter is
causing the oPE02 to be declared. When multiple errors
occur at the same time, other errors are given precedence
over oPE02.
The same function is assigned to two multi-function inputs (excludes "Brake
Feedback NO" and "Brake Feedback NC."); the Brake Feedback is assigned
to three or more multi-function inputs.
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.
Contact CNFM NO and Contact CNFM NC are selected simultaneously.
• Check for contradictory settings assigned to the multi-function input
terminals simultaneously. Correct setting errors.
The drive, control board, or terminal board has been replaced and the
parameter settings between the control board and the terminal board no
longer match.
• To load the parameter settings to the drive that are stored in the terminal
board, go to the U6 menu and select Term -> Ctrl Int. Initialize parameters
after drive replacement by setting U5 to Factory Defaults.
Speed reference is assigned to an option card but an input option card is not
connected to the drive; the Up/Down command is assigned to an option card
but an input option card is not connected to the drive.
• Reconnect the input option card to the drive.
A control method has been selected that requires a PG option card to be
installed, but no option card is installed.
• Connect a PG option card.
