How to restart after stopping with
(PS) release method)
● PU stop release method for operation panel (FR-DU08)
After completion of deceleration to a stop, switch OFF the STF and STR signal.
Press PU/EXT key three times. (
(When Pr. 79 "Operation mode selection" = "0 (initial value) or 6")
When Pr. 79 = "2, 3, or 7", PU stop can be released by pressing one time.
● PU stop release method for parameter unit (FR-PU07)
After completion of deceleration to a stop, switch OFF the STF or STR signal.
Press EXT key. (
Fig. 5-77:
● The motor can be restarted by resetting the power supply or resetting with a RES signal.
Even when Pr. 250 "Stop selection" ≠ "9999" is set and coasting stop is selected, deceleration stop
NOTE
and not coasting stop is performed in the PU stop function during External operation.
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-A820-03800(75K) or higher and FR-A840-
02160(75K) or higher.
NOTES 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.
