2.
Press the PU/EXT key three times (the PS warning is reset)
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.
• 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) (for the safety communication model only)
• When "10" is set in P.E107 or any value from "10000 to 10003, 10014 to 10017" is set in Pr.75, the reset command input
(using the STOP/RESET key or the RES signal) is disabled when the protective function (E.SAF) is activated. Turn ON the
power supply of the inverter again to reset the inverter.
NOTE
• When a communication option is installed, reset is enabled when the protective function (E.SAF) is activated regardless of
P.E107 or Pr.75 setting.
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.
