 How to restart the inverter which has been stopped in the External
operation mode by using
("PS" (PU stop) warning reset method)
• For the operation panel (FR-DU08)
1.
After completion of deceleration stop, turn OFF the STF and STR signals.
2.
Press
when Pr.79 Operation mode selection = "0 (initial value) or 6".
When Pr.79 = "2, 3, or 7", the PU stop warning can be cleared with one keystroke.
• For the parameter unit (FR-PU07)
1.
After completion of deceleration stop, turn OFF the STF or STR signal.
2.
Press
EXT
• The inverter can be restarted by performing the reset operation (by turning OFF and ON the power or inputting the RES
signal).
NOTE
• Even when Pr.250 Stop selection ≠ "9999" is set and coasting stop is selected, using the PU stop function in the External
operation mode does not provide coasting stop but deceleration stop.
 Reset limit (P.E107)
• Setting P.E107 = "1" or Pr.75 = any of "100 to 103, or 114 to 117" will make the inverter to refuse any reset operation (RES
signal input, etc.) for 3 minutes after the first activation of an electronic thermal O/L relay or protective function (E.THM,
E.THT, E.OC[]).
• The reset limit function is available with the FR-F820-03160(75K) or higher and the FR-F840-01800(75K) or higher.
NOTE
• Resetting the inverter power (turning OFF the control power) clears 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.
