Selecting retry generating faults (Pr.65)
• Using Pr.65, you can select the fault that will cause a retry. No retry will be made for the fault not indicated. (For the fault

When Pr.249 Earth (ground) fault detection at start = "2", retry is not performed.
NOTE
• Use the retry function only when the operation can be resumed after resetting a protective function activation. Making a
retry against the protective function, which is activated by an unknown condition, will lead the inverter and motor to be
faulty. Identify what condition the protective function was activated, and eliminate such condition before resuming the
operation.
• If the retry function operates during PU operations, the operating conditions (forward/reverse rotation) are stored; and
operations resume after retry reset.
• Only the fault details for the first fault that occurred are stored in the fault history.
• The reset by the retry function does not clear the accumulated data of the electronic thermal O/L relay. (This is different
from power supply reset or reset by RES signal.)
• When the Parameter storage device fault (control circuit board) (E.PE) is occurring and reading of the retry-function-related
parameters is not possible, retry cannot operated.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
CAUTION
• When the retry function is set enabled, stay away from the motor and machine in the case of an inverter trip. The motor and machine will
start suddenly (after the reset time has elapsed) after the inverter trip. When the retry function is set enabled, apply in easily visible
places the CAUTION stickers supplied to this product.
