PARAMETERS
(4) Restarting method when stop was made by pressing from the PU during external
operation
• The motor can be restarted by making a reset using a power supply reset or RES signal.
(5) Reset limit
• Setting can be made for the 02160 or more.
• You can set Pr. 75 to disable reset operation until the thermal cumulative amount reaches 0 when a thermal trip
(THM, THT) or an overcurrent trip (OC1 to OC3) occurs consecutively twice.
• When Pr. 75 = "100 to 103, 114 to 117", reset limit is made valid.
(a) When operation panel (FR- DU07) is used
1)After the motor has decelerated to a stop, turn off the
STF or STR signal.
2)Press to display .••••••( canceled)
3)Press to return to .
4)Turn on the STF or STR signal.
(b)
Connection of the parameter unit (FR-PU04/FR-PU07)
1)After the motor has decelerated to a stop, turn off the
STF or STR signal.
2)Press .••••••( canceled)
3)Turn on the STF or STR signal.
CAUTION
⋅ If Pr. 250 Stop selection is set to other than "9999" to select coasting to a stop, the motor will not be coasted to a stop but
decelerated to a stop by the PU stop function during external operation.
To restart after the inverter is stopped by PU with PLC function, reset using a power supply rest or RES signal. (sending stop
signal from GX Developer, can also perform the reset.)
CAUTION
Do not reset the inverter with the start signal on. Doing so will cause the inverter to start immediately after a
reset, leading to hazardous conditions.
REMARKS
When the power-on reset (no control power is supplied) is made, the thermal cumulative amount is cleared.
