 Reset limit function (P.E107)
• When P.E107 = "1" or Pr.75 = any of "100 to 103 and 114 to 117", if an electronic thermal O/L relay or an overcurrent
protective function (E.THM, E.THT, E.OC[]) is activated while one of them has been already activated within 3 minutes,
the inverter will not accept any reset command (RES signal, etc.) for about 3 minutes from the second activation.
• The reset limit function is available with the FR-F860-01080 or higher.
NOTE
• Resetting the inverter power (turning OFF the control power) will clear the accumulated thermal value.
• When the retry function is set enabled (Pr.67 Number of retries at fault occurrence  "0"), the reset limit function is
disabled.
CAUTION
• Do not perform a reset while a start signal is being input. Doing so will cause a sudden start of the motor, which is dangerous.
