5.3 (H) Protective function parameter
Selecting retry generating faults (Pr.65)
• Using
Pr.65
, the fault that causes a retry is selectable. No retry is made for the fault not indicated. (For the fault details,

●
indicates the faults selected for retry.
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 converter unit to be faulty. Identify
and remove the cause of the protective function activation before restarting the operation.
• Only the first fault is recorded in the fault history during retries.
• 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 (E.PE) is occurring and reading of the retry-function-related parameters is not
possible, retry cannot be operated.
• Changing the terminal assignment using
Pr.190 to Pr.195 (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 output shutoff. The motor
and machine will start suddenly (after the reset time has elapsed) after the shutoff. When the retry function has been
selected, apply the CAUTION sticker(s), which are supplied with the inverter, to easily visible places.
