NOTE
• When the "retry" (Pr.523 = "200") is selected, it is recommended to use the automatic restart after instantaneous power
failure function at the same time.
• Parameter setting is not available during emergency drive operation.
• To return to the normal operation during emergency drive operation, reset the converter unit or the inverter, or turn OFF the
power supply. (The operation will not be returned to normal only by turning OFF the X84 signal.)
CAUTION
 When the emergency drive operation is performed, the operation is continued or the retry is
repeated even when a fault occurs, which may damage or burn the inverter, converter unit and
motor. Before restarting the normal operation after using this function, make sure that the inverter,
converter unit and motor have no fault. Any damage of the inverter, converter unit or the motor
caused by using the emergency drive function is not covered by the warranty even within the
guarantee period.
