(H) Protective function parameter
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
details, refer to page 629.)

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, regenerative brake
duty, etc. (This is different from power supply reset or reset by RES signal.)
• When the parameter storage device fault (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.
